Prof Kelly Chibale (centre front) and his team have brought the world closer than ever before towards finding a cure for malaria.(Image: H3-D) The female Anopheles mosquito picks up the disease when she drinks the blood of an infected person and transmits it when she moves to the next person..(Image: Centres for Disease Control)MEDIA CONTACTS • Elaine Rutherfoord-JonesAdministrator, H3-D Drug Discovery andDevelopment Centre+27 21 650 5495Lorraine KearneyA malaria-free world: this is a tantalising possibility that may be now within our grasp. And it’s a proudly South African project, says Prof Kelly Chibale, the director and executive committee member of the Drug Discovery and Development Centre (H3-D) at the University of Cape Town (UCT).Last week, flanked by the professor, Science and Technology Minister Naledi Pandor announced the discovery at the centre of a potential single oral dose cure for malaria, the holy grail in lightening the world’s disease burden.Chibale, who is the lead researcher of the collaborative research project, explains: “This is a potential cure for malaria. It is now entering the clinical trial phase – clinical trials should begin at the end of 2013. If the trials are successful, then not only will we have a cure for malaria, but it will also have the potential to stop person-to-person transmission of the parasite.”The breakthrough is huge: at stake is the possibility of eradicating malaria at some stage in the future, he stresses.“With this molecule, we have a potential drug that works at all life cycle stages of the parasite, including at the blood stage, and at the stage where transmission back to the mosquito occurs.”Essentially, this means that it would stop the parasite from infecting mosquitoes when they bite people who have malaria.Work started on the discovery back in early 2008, in Geneva, Switzerland. Dr Tim Wells, the chief scientific officer at the Medicines for Malaria Venture (MMV) was about to start a campaign to test chemical samples to find new compounds that would act against the human malaria caused by the Plasmodium falciparum parasite. He was working with Prof Vicky Avery at the Eskitis Institute at Griffiths University in Brisbane, Australia.The H3-D was set up in April 2010 through the joint efforts of MMV, UCT and other international stakeholders, as well as the South African government. They included Cape Biotech Trust, which is now part of the Technology Innovation Agency.The project that led to the discovery of MMV390048 in September 2010 began on 1 April 2009, and became a purely South African venture in January 2012.Professor Chibale explains that the discovery, which happened at UCT, was particularly significant because it was the first-ever clinical molecule discovered by Africans. It will be the first clinical candidate researched in Africa.How malaria worksOnce a person is bitten by a carrier mosquito and is infected, the parasite attacks the person’s liver. Malaria is transmitted by mosquitoes of the Anopheles genus, and in Africa the culprit is the A. gambiae complex of seven indistinguishable insects.At this stage, there are no symptoms of the disease. It multiplies rapidly in the liver and invades the blood, causing red blood cells to explode. Debilitating sickness sets in, often leading to death, particularly among children. But the MMV390048 molecule could also potentially work as a prophylaxis, Chibale points out.Taken before you entered a malaria area, it could prevent the parasite from multiplying if you were bitten. And for those people who lived in malaria areas, who can have several episodes of the disease a year, it could protect them from reinfection.The potential cure can make other claims: it works on all strains of the disease, including that found in Africa, which is mostly from P. falciparum, the most deadly, and that found in Asia, mostly from P. vivax, which is responsible for relapse. And it works on drug-resistant strains of malaria. But perhaps most importantly, it is a potential cure.“Our definition of a cure is that after 30 days there is not a single parasite in a sample from a live animal. Chloroquine, one of the drugs used now to treat malaria, does not cure in the same animal model; there are still some parasites in the blood of animals treated with chloroquine 30 days after treatment,” the professor explains.“This is very exciting. It is a single dose, while other drugs need high multiple doses in the same animal model. This has huge cost and compliance [medicine adherence] implications. People often take a drug, feel better and stop taking the medication. But they still have the parasite in their systems. This leads to drug-resistance. This molecule could stop this.”Cost is a big issue. “We want it to be a single oral dose costing less than a dollar per treatment. This was one of the issues we identified in the lead optimisation phase of development.”The molecule is synthetic, from the aminopyridine class, helping to keep costs down. It is made in the laboratory from readily available resources. Supply issues are very important in drug manufacture, and this molecule can be made in a few steps, which makes it cheaper, Chibale stresses.“During the crucial lead optimisation phase, we tested for cardiotoxicity and drug-drug interaction risks. Then, the penultimate phase was the candidate profiling stage, when we gathered data, mostly on safety – because the safety of future patients is the most important thing. Once we had a dossier, we presented it to Medicines for Malaria Venture’s expert scientific advisory committee in July. They approved the molecule for clinical development.”MMV’s funders include BHP Billiton and Exxon Mobile.Clinical trials nextThe next step, now being taken, is preparing for clinical trials: patients and volunteers need to be recruited and permission needs to be granted by the authorities. A commercial venture also needs to be found to manufacture the drug at scale.“This is being discussed now. The idea is to do as much as possible in South Africa.”Developing the molecule has been a steep but worthwhile learning curve for the scientists at UCT.“We have no guarantee on the clinical trials,” Chibale says. “But we have so many positive spin-offs so far. We’ve been able to develop skills and expertise. Lessons have been learned. And the skills are now being used for other illnesses. Now we know how to discover drugs – it is not only a gift to Africa, but a gift to the world.“It also provides employment, such as in manufacturing. And we now have back-ups. We have a healthy pipeline to keep discovering and making useful drugs. Because it is a continuous war against the organisms. They want to live, and they are very clever, so we need to keep finding new ways to beat them, because we want to live too.”Funding for the project came from the Department of Science and Technology, which invested R25-million (US$3-million). Chibale also has a research chair from the department. MMV invested about R15-million ($1.8-million), and UCT provided the infrastructure and some funding. A partnership has also been set up between MMV and the department’s Technology Innovation Agency, and the project is now being funded by the two entities on a one for one basis. It has been scaled up with this new funding, and the team has been able to expand from four to 10 scientists.If MMV390048 indeed proves to be a cure, the implications will be far-reaching. Malaria plays a big role in the cycle of poverty, Chibale points out. It debilitates its victims; they cannot work and take weeks to recover. Without proper nutrition and the ever-present possibility of reinfection, the disease’s toll is massive in human terms and on productivity.A child dies every 46 seconds from malaria in sub-Saharan Africa, and 90% of malaria deaths take place in sub-Saharan Africa, Dr Tom Ellman, head of Medecins Sans Frontieres South African Medical Unit, was quoted as saying in the Daily Maverick. It was estimated that African economies lost up to R100.5-billion ($12-billion) a year directly related to malaria and its impact on productivity.Malaria fact sheetThe World Malaria Report 2011 issued by the World Health Organisation in December 2011 reported:There were 216 million cases of malaria in 2010; 81% of these were in the WHO African Region.An estimated 3.3 billion people were at risk of malaria in 2010.An estimated 655 000 people died of malaria in 2010; 86% of the victims were children under 5 and 91% of malaria deaths occurred in the WHO African Region.In 2010, there were 46 malaria-endemic countries in sub-Saharan Africa; 43 of these belong to the WHO African Region, and three (Sudan, Somalia and Djibouti) were in the WHO Eastern Mediterranean Region.45 countries around the world have identified resistance to at least one of the four classes of insecticides used for malaria vector control; 27 of these are in sub-Saharan Africa.Estimated malaria cases and deaths by WHO Region, 2010Region Estimated cases Estimated deathsAfrican Region 174-million 596 000Americas Region 1-million 1 000Eastern Mediterranean Region 10-million 15 000European Region 20 0South-East Asia Region 28-million 38 000Western Pacific Region 2-million 5 000
Ramatlhodi was the ANC president’s speechwriter. He recalls a sharp dresser who was meticulous in his attention to detail and unwaveringly dedicated to liberation.Ngoako Ramatlhodi remembers Oliver Tambo as meticulous, in dress and turn of phrase. (Image: Ngoako Ramatlhodi)Amukelani ChaukeThe late struggle stalwart Oliver Reginald Tambo was a perfectionist – he was so thorough and meticulous that in the late 1980s and early 1990s, he would make his speechwriters rewrite drafts until he was satisfied.In some instances, he would end up only reading the opening paragraphs of the speech and deliver the remainder of his address off-the-cuff.Before the era of computers, former public service and administration minister advocate Ngoako Ramatlhodi, who was a youth activist in his thirties at the time, was appointed speechwriter to the then exiled ANC president at a time when political parties were banned.Between 1987 and 1993 – during which time Tambo’s health took its toll following a stroke in the mid-1980s – Ramatlhodi, who had gained much political insight through his work in youth structures in exile, grew close to Tambo.The president was navigating sensitive political terrain while South Africa was on a knife’s edge and was on the verge of opening negotiations that would dismantle the apartheid regime.In an interview Ramatlhodi said that looking back on that period, writing for a selfless, great struggle stalwart such as Tambo was at times challenging and in some instances, very insightful.The advocate was part of a committee in the Presidency with veteran struggle stalwarts Jack Simons, Edwin Mabitse (real name Edward Mabitsela) and the first Speaker of the democratic parliament Frene Ginwala, who was based in London.“The two of us [Ramatlhodi and Mabitse] were made the president’s speech writers and secretaries and then we formed a committee in the Presidency with Jack Simons.“[We] would be faced with typewriters on a daily basis and the old man was a perfectionist – he would mark us red – there were no computers in those days. So if it is marked red, that means you are going to start afresh on the typewriter all over again.“But he would give us work quite ahead of time. Let’s say he was going to make a speech in May, he would then say a month before we should start drafting that speech, or a month and a half before. Then we kept on taking the drafts to him and he looks at them, asks you questions like ‘Do you understand what you are saying? Do you think the president of the ANC would say this like that?’“If you were properly dressed he would take off his glasses and say: ‘You look so smart.” (Image: Brand South Africa)“Then he puts you back in line and says I think you should articulate this thing this way and this way. And you would go and do a rewrite,” he said.In February, President Jacob Zuma declared 2017 the year of OR Tambo to recognise the struggle stalwart’s contribution to the liberation struggle. Ramatlhodi said Tambo was “a patriot” who cared about language.“He knew the politics, he had the content… He was very passionate about the liberation of our people and even in hard times, when he [fell ill] before 1985, he had a stroke and then we went to this conference in… Zambia and there he said ‘My body is weak; it is limping. But what remains of it shall be consumed in the struggle.’“He was definitely clear that he was going to fall with his boots on and I think that is what happened.”The rise of OR TamboBorn on 27 October 1917 in Kantilla, Bizana, in Mpondoland in the Eastern Cape, Tambo ran an attorney’s practice with Nelson Mandela in central Johannesburg in 1951 before Mandela was banned. This was after he joined the ANC in 1940.In 1953, Tambo’s profile as an anti-apartheid activist rose and he replaced the then national secretary, Walter Sisulu, who had been banned by the government for his role in the 1952 Defiance Campaign. In 1957, Tambo was elected deputy president of the ANC.Subsequent to the Sharpeville Massacre on 21 March 1960, Tambo embarked on a Mission in Exile to gain international support for the South African liberation movement. He became ANC president in 1969, a position he kept until 1991, making him the longest-serving president of the ANC.Ramatlhodi handed the penIn the late 1980s he recruited Ramatlhodi as his private secretary and speechwriter. At the time, Ramatlhodi was head of the ANC’s Regional Political and Military Council of the Zimbabwe Mission. He had spent time in Lesotho, where he was the student representative council (SRC) president at the National University of Lesotho. Former Reserve Bank governor Tito Mboweni was the secretary responsible for publicity in the same student body.Usually, Ramatlhodi would travel to Angola for military training and return to Lesotho to continue his studies. But on one occasion, he was told to go to Lusaka in Zambia because he “was needed” there.He was taken to the ANC’s headquarters in exile, where the liberation movement’s top officials were waiting for him, as was Mboweni.Ramatlhodi and Mboweni were briefed about what has taking place in Lesotho. Times were tense: the South African Defence Force had massacred ANC members in Lesotho, Botswana and Mozambique.Their appointment as envoys was mainly the result of the access they had to frontline leaders and ministers, including the prime minister of Lesotho at the time, through their SRC positions.Ramatlhodi was later deported from Lesotho and was sent to Russia. There, he did military combat work and on his return to Africa, he was put in charge of the council in the Zimbabwe Mission, when the ANC was devising a strategy to start negotiations with the apartheid regime.In 1987, he was appointed speechwriter to Tambo and formed part of the team that went on to draft the Harare Declaration.The Constitutional PrinciplesRamatlhodi said one of the most important documents he wrote under Tambo’s watch was the Constitutional Principles, which he co-drafted under the ANC Constitutional Committee to define a debate on the country’s new constitution.“We used to write [a lot of documents] but one of them had to do with the conditions for negotiations, which was a statement issued by the ANC on the conditions of negotiations, release of political prisoners, the unbanning of political organisations, all those things.“There are many, many documents that I wrote. For example, the Constitutional Principles of the region, which I participated in even when I was in Harare.”The Harare DeclarationIn 1989, Ramatlhodi was part of the team that drafted the liberation movement’s Harare Declaration, a historic paper that laid the basis for negotiations between the apartheid regime and the liberation movement.He said this was one of the most important pieces of writing that he was part of as Tambo’s speechwriter.“When we were drafting the Harare Declaration in 1989, we did a tour of the frontline seat – …Tanzania, Zimbabwe… for a week.“What happened was we wrote a draft… and sent it to people in South Africa and the neighbouring states for their comment and then we followed up to engage with the authorities so that they made their inputs into the final outcome of that document.”After the roadshow, they returned to Luanda in Angola to draft the final document before proceeding to Lusaka. In the group was former president Thabo Mbeki; ANC strategist and former head of policy and in the co-ordinating advisory unit in the Presidency Joel Netshitendzhe; intellectual and activist Pallo Jordan, former member of parliament and minister; and former justice minister Penuell Maduna.Ramatlhodi said Tambo was of the opinion that the document underemphasised the role of the armed struggle in the liberation war. He instructed Ramatlhodi to return to the team and raise the view as his own.“That’s Oliver Tambo for you. He did not want it to come from him because they would easily be persuaded because the president said so. So I had to go argue on that point on his behalf. So it illustrates the point that he was not self-imposing,” he said.The stroke and the comeback speechTambo suffered a mild stroke in 1981; eight years later, on 9 August 1989, he suffered a more severe stroke in Lusaka and was rushed to London. During his recovery, Ramatlhodi was sent to the British capital to help him regain his speech, as Tambo was only comfortable with people familiar to him.“Towards December that year the ANC was going to have a conference in South Africa, so I went back to help him regain his speech because he was comfortable with familiar surroundings.“We prepared the speech, which was a comeback speech, after 27 years, and he delivered it at the ANC conference at Nasrec, which was the first legal ANC conference in South Africa since 1960.“I showed him that speech on the machine manually. But the good thing about him – he was a fighter – by the time he returned [to South Africa], he was reading the speech. And he made many other speeches across the country subsequently,” said Ramatlhodi, who was 39 at the time.This followed then state president FW de Klerk unbanning all anti-apartheid political parties in February 1990, paving the way for negotiations that would end apartheid.Tambo delivered the speech on 16 December 1990 at a rally following the close of the ANC elective conference. It was at this gathering that Mandela was elected Tambo’s deputy president.In his speech, Tambo said: “South Africa is at the crossroads. Our struggle, complemented by efforts of the international community, has rendered apartheid unworkable. Thus, those who rule us without our consent have been compelled to accept the humanity of a black person in this country. For the first time in a period of 70 years, the legitimate aspirations of the overwhelming majority of our people have possibilities of being realised.”Tambo made several more speeches written by Ramatlhodi and at the ANC’s 48th National Conference in Durban in July 1991, he delivered what seemed to be a farewell speech in his opening address. He later told delegates of his intention to step down, urging them to support Mandela as his successor.After he declined a nomination to be president again, delegates created the national chairperson position in honour of Tambo.In the early hours of 24 April 1993, Tambo suffered his third and fatal stroke – two weeks after the assassination of Chris Hani, then leader of the SA Communist Party and Umkhonto we Sizwe chief of staff.Tambo the smart dresserRamatlhodi said while it was usually all hard work and putting pen to paper to craft speeches and document what would later become the liberation movement’s most-prized possessions, he remembered an ANC president who was a smart dresser.“He loved his clothes. And he wanted us to dress very well. If you were shabbily dressed he would look at you and [ask] ‘Ngoako, don’t you have clothes?’“I remember on one trip [during] the Harare Declaration, I don’t think I had enough suits with me. He called the late Stanley Mabizela and said ‘Take this man to town and buy him clothes.’ He gave him money. I got about three nice suits that day.“If you were properly dressed he would take off his glasses and say: ‘You look so smart.’”One of Ramatlhodi’s favourite phrases from the speeches he wrote was “United in our diversity”.“That line comes from a paragraph in our speech where we say: ‘We seek to create a united, democratic and non-racial society. We have a vision of a South Africa in which black and white shall live and work together as equals in conditions of peace and prosperity.’ Tambo made this speech at Georgetown University in Washington, DC on 27 January 1987. At this time, South Africa was at the height of the armed struggle.”Following his time as Tambo’s speechwriter, Ramatlhodi stayed on in the office of the Presidency when Mandela for about six months after Mandela took over. This was while Mandela, affectionately known as Madiba, embarked on a world tour as ANC president.Would you like to use this article in your publication or on your website?

Fall herbicide applications are good tool for controlling existing weeds after harvest, which will provide a weed free field in early spring the following year.According to Mark Loux, OSU Weed Specialist, “Even where the herbicides lack residual, the fall treatment seems to enable more effective control of marestail the following season. In some cases, it’s probable that you don’t even know how much the fall treatment helps out, but our research shows that more often than not it does.”University research also suggests that most fall applied herbicides provide minimal residual control in the spring and that the greatest benefit from residual herbicides is gained from a spring application. The timing of fall herbicide applications is important to ensure control of existing weeds.“In our research, herbicides seem to be effective for control of winter annuals and biennials well into December. The rate of plant death can slow considerably, but this is not a problem since weeds just have to die by early spring. Control of perennials typically declines in late November or early December though, depending upon weather,” writes Loux.University experts have published several excellent articles on this subject that go into great detail, all of which are available online. Below are some effective fall herbicide treatments recommended by Ohio State University research. Keep in mind; it is important to make application decisions based on the weeds present and the crop to be planted the following spring.Any Crop Next Spring: -Glyphosate + 2,4-DSoybeans next spring: Canopy EX or DF + 2,4-D Glyphosate + 2,4-D Metribuzin + 2,4-D (excluding dandelions)Corn next spring: Basis + 2,4-D Glyphosate + 2,4-D Simazine + 2,4-D (except dandelion)For more information about fall weed control check out these articles from Purdue and Ohio State.
In the past decade, wind energy production has soared in Spain, rising from 6% of the country’s electricity generation in 2004 to about 20% today. While that is certainly good news for boosters of clean energy, the surge in renewables has come with the challenge of ensuring that electric power is available when customers want it, not just when the wind blows.To help accommodate the increased supply of wind, Spain’s utilities have turned not to high-tech, 21st-century batteries, but rather to a time-tested 19th-century technology — pumped storage hydroelectricity. Pumped storage facilities are typically equipped with pumps and generators that move water between upper and lower reservoirs. A basic setup uses excess electricity — generated, say, from wind turbines during a blustery night — to pump water from a lower reservoir, such as behind a dam, to a reservoir at a higher elevation. Then, when the wind ceases to blow or electricity demand spikes, the water from on high is released to spin hydroelectric turbines. Total capacity is now 142 gigawattsCurrently, 292 pumped storage hydro facilities are in operation worldwide, with a total capacity of 142 gigawatts. Another 46 projects, with a total capacity of 34 gigawatts, are being developed, according to the U.S. Department of Energy’s Global Energy Storage Database.Chemical batteries are typically installed at the electricity distribution level, where in addition to storage they provide other services, such as closing the gap between supply and demand in increments measured in milliseconds, notes Ruud Kempener, an analyst with the International Renewable Energy Agency in Bonn, Germany. The capacity of batteries is typically in the single to tens of megawatts.In contrast, the capacity of pumped storage hydro systems ranges from the hundreds to thousands of megawatts, providing flexibility to the electric system as a whole, a role that Kempener says will increase in importance in the future. He was lead author of a recent report that found pumped storage hydro would need to increase to 325 gigawatts by 2030 from about 150 gigawatts today in order to double the share of renewable energy in the global mix.Recent energy policy reforms in Spain have halted the hyper growth of renewables there. Still, several new pumped storage projects have recently come online in Spain, with more being developed in Germany, Austria, and Italy. In Italy, Swiss utility Repower is gaining approvals for its planned 572-megawatt Campolattaro pumped storage plant about 55 miles northeast of Naples, which would pump water from a dammed lake to a newly constructed reservoir in nearby hills.Pumped storage hydro is growing fastest in China, according to Chi-Jen Yang, a research scientist at the Center on Global Change at Duke University in Durham, North Carolina. “A new pumped hydro station comes online every several months,” he says, adding that “there are 10 or 15 under construction right now and each one is really huge, like 1 gigawatt or bigger.”China’s 22 gigawatts of installed pumped storage hydro capacity recently surpassed the United States’ 21 gigawatts and will overtake world leader Japan’s 27 gigawatts in 2018, according to Yang. The 3.6-gigawatt Fengning Pumped Storage Power Station under construction in Hebei Province will be the world’s largest when it comes online around 2022. John Roach is a Seattle-based journalist who covers technology, science and the environment. This post originally appeared at Yale Environment 360. Obstacles to new hydro facilitiesBuilding new pumped storage hydro faces numerous obstacles, especially in the United States. Public and private sector support for chemical batteries can outweigh interest in pumped hydro. Other challenges include the hundreds of millions of dollars in upfront capital, long construction times, and market structures that give insufficient value to grid flexibility.These hurdles have hobbled the Klickitat County Public Utility District’s effort to construct the JD Pool Pumped Storage Hydroelectric Project along the Columbia River. Renewed interest is percolating, however, according to Randy Knowles, a commissioner for the utility district who has promoted the project for more than a decade. HydroChina Corp., a major hydropower construction firm based in Beijing, signed a memorandum of understanding with the county this October to discuss collaborating on the project. “They have an interest in entering the U.S. market, and this is a real attractive project given its size,” Knowles says.Since 2000, 47 wind projects have been developed in Washington and Oregon within about 50 miles of the proposed project site. The turbines have a combined capacity of 4,695 megawatts and generate enough electricity to power about 800,000 homes, according to data from the Northwest Power and Conservation Council. Power lines carry the electricity wrung from the wind to high-voltage transmission lines that lead away from the John Day Dam.Most of the time, the dam, and others in the Columbia Basin, work in concert with the wind turbines. When the wind slackens, for example, grid operators send more water through the dams to keep up with demand. When the wind howls, flows through the dams are reduced to save water until it’s needed. In a sense, the dams act as a giant battery that compensates for the intermittency of the wind, ensuring a low-carbon means to keep the lights on from Seattle to Los Angeles.But the capacity of the hydroelectric dams to accommodate wind generation is about maxed out, according to Knowles. In the spring of 2011, for example, the Bonneville Power Administration, the federal agency that operates the dams, ordered many Pacific Northwest wind farms to shut down generation for several hours a day to accommodate water releases (and a resulting surplus of hydroelectric generation) that was legally required to maintain safe passage for migrating fish.The Klickitat County Public Utility District’s proposed 1,200-megawatt project, Knowles says, would reduce the wind sector’s reliance on the dams, allow more wind turbines on the Columbia Plateau, and, in the process, help the United States meet long-term emissions reduction targets.“We are just ahead of the curve, frankly, in recognizing the need,” he says. “So at some point everybody will catch up and the project will get built.” The technology dates from the 1890sPumped storage hydro was first used in the 1890s in the Swiss, Austrian, and Italian Alps to provide greater flexibility for the management of water resources. The technology was widely adopted in the 1960s, ’70s, and ’80s to provide load shifting, which transfers electric generation from peak hours to off-peak hours of the day, according to Koritarov. The technique allows utilities to continually operate large, inflexible assets such as nuclear and coal-fired power plants at their optimal efficiency. Surplus generation from these plants is used to fill storage reservoirs; when demand peaks, the water is released to generate additional electricity. When nuclear and coal plants stopped being built, “the pumped storage also quit being built,” he says.Pumped hydro in Spain: The upper reservoir of the Cortes-La Muela hydroelectric station in the municipality of Valencia, Europe’s largest such facility.Today’s growth in pumped storage hydro is strongest where access is limited to inexpensive natural gas-fired “peaker plants,” which are built to run specifically during times of high demand, such as the late afternoon on hot summer days. Peaker plants are also increasingly used to fill the gap when the wind dies or clouds blot the sun, causing a drop in intermittent renewable generation. Pumped storage hydro can perform the same tasks. An added bonus of pumped storage hydro is the capacity to absorb excess electricity, Koritarov says. Wind generation, for example, is typically highest at night, when demand is lowest and the electricity is often unwanted.Pumped storage hydro requires more energy than it produces, notes Yang, meaning that the technology only makes sense in electric power systems that have surplus generation during certain parts of the day and lulls at others.The technology is not without environmental costs. Their operation leads to rapid fluctuations in reservoir water levels as the systems switch between pumping water from dam reservoirs to elevated storage reservoirs, and then lowering those upper reservoirs during electricity generation. “You may have an artificial flood for four hours, and then a drought for 20 hours, and then another artificial flood,” Peter Bosshard, the interim executive director for International Rivers, an environmental advocacy based in Berkeley, California, says. Such fluctuations wreak havoc on the ecologically rich areas where terrestrial and freshwater ecosystems overlap.“We are seeing that there are other, more interesting ways of storing electricity coming up on the horizon, in particular battery storage through distributed systems,” Bosshard says. New projects in the U.S.In the United States, the Federal Energy Regulatory Commission issued licenses for two projects in 2014, both in California. The Sacramento Municipal Utility District’s $800 million, 400-megawatt Iowa Hill Pumped-Storage Project involves construction of a reservoir 1,200 feet above Slab Creek Reservoir, along with an underground powerhouse and tunnels to connect the water bodies. Eagle Crest Energy Company’s $1.4 billion 1,300-megawatt Eagle Mountain Pumped Storage Project involves construction of upper and lower reservoirs at an old iron mine near Joshua Tree National Park.Several dozen other U.S. projects are in the early planning and preliminary study stages. These include the $2.5 billion, 1,200-megawatt JD Pool Pumped Storage Hydroelectric Project in Washington State, which would site a pair of upper reservoirs between strings of wind turbines on the Columbia Plateau and a lower reservoir, located 2,400 feet down the wall of the Columbia River Gorge at an abandoned aluminum smelter near the John Day Dam. Planners envision close coordination among Columbia River dams, large arrays of wind turbines, and the proposed pumped storage facilities, which would hold water in reserve during steady winds and unleash it during calm periods. That’s precisely what the giant Spanish utility Iberdrola has done with the expansion to its $1.3 billion Cortes-La Muela hydroelectric scheme, completed in 2013. The company uses surplus electricity to pump water from the JÃºcar River to a large reservoir on a bluff 1,700 feet above the river. When demand rises, the water is released to generate electricity. The 1,762-megawatt pumped storage generating capacity is Europe’s largest and is part of a hydroelectric complex capable of powering about 500,000 homes a year.While much of the buzz around energy storage today centers on the development of innovative battery technologies, more than 98% of installed storage capacity globally is, in fact, pumped hydro, according to Vladimir Koritarov, an energy systems engineer at the Department of Energy’s Argonne National Laboratory in Illinois. And today, fueled by the world’s embrace of solar and wind power to help combat global warming, pumped storage hydro is in the midst of a surge, with power generators and utilities building new facilities from Italy to China as a way of balancing supply and demand across electric power grids.“Among all energy storage technologies,” Koritarov notes, “pumped storage hydropower is still the only one that is mature, reliable, proven, and commercially available to provide large utility-scale energy storage.” RELATED ARTICLES Spanish Island Kicks the Oil HabitA Novel Way to Store Energy Surge in Renewables Remakes California’s Energy LandscapeUndamming Rivers Could Make Room for PV
