Major MeerKAT tender awarded

7 August 2009

South Africa's Square Kilometre Array project team has awarded a R46-million contract to build a specialised overhead power line and fibre-optic cable system for the MeerKAT radio telescope to local company Optic 1.

The MeerKAT (also known as the Karoo Array Telescope) will operate 24 hours a day for 20 to 30 years, and will need up to four megawatts of power when the instrument is fully operational.

Completion of the construction of MeerKAT is scheduled for December 2012, with commissioning in 2013. The MeerKAT telescope is a precursor instrument to the world's largest radio telescope, the Square Kilometre Array (SKA), which will be built either in South Africa or Australia.

Optic 1 is a leader in the field of supplying and securing power lines.

"The power line has required a unique design, sophisticated hardware and metering equipment, as well as novel insulation and bonding methods, to suppress any radio waves that may interfere with the sensitive receivers of the MeerKAT," SKA South Africa infrastructure manager Tracy Cheetham said in a statement this week.

Karoo substation upgrade

The new 33 kV power line will run from the Karoo substation just outside Carnarvon in the Northern Cape to the SKA site about 80 kilometres away. Once complete, the new overhead line will be operated and maintained by state company Eskom.

Installation of the power line will kick off with the construction of 73.5 kilometres of wooden pole structure from Carnarvon to the site, followed by 35 kilometres of steel monopole structures to the core of the SKA site.

The transition from wooden pole structures to steel pole structures provides better earthing, an important design consideration to reduce sparking that could cause unwanted radio frequency interference.

The new transmission line will initially be operated at 22 kV and should be complete by December 2009. The second phase of the project entails the upgrade of the Karoo substation from 5 MVA to 10 MVA, and operating the new transmission line at 33 kV.

"We are investigating a hybrid final power solution for MeerKAT that will combine the use of grid power with solar energy," Cheetham said.

The Centre for Renewable and Sustainable Energy Studies at Stellenbosch University, along with a team from Hatch Africa, are currently doing a feasibility study on supplying concentrated solar power to MeerKAT.

Fibre optic connection

The telescope will be connected to a control centre in Cape Town by an optical fibre cable, and this tender includes the construction of the optical fibre from Carnarvon to the site. The fibre-optic cable will be operated by state-owned connectivity provider Broadband Infraco.

"This is a great challenge and one of our most remarkable projects ever," said Dirk Van der Westhuizen, technical director of Optic 1, which is based in Brits in North West province.

"We are delighted to be a part of building the MeerKAT telescope, a project that all South Africans can be proud of."

CleanTech Achates Power

San Diego based startup is one of 15 companies the Cleantech Group spotted in the past week looking to raise money. Find out more in the Pitch o’ the week.

The same fuel efficiency that drew Europeans to embrace diesel engines is taking hold of the U.S., and startup Achates Power is ready to pounce.

The San Diego, Calif-based company spent four years developing a diesel engine technology that  offers 50-percent improvement in fuel economy at a cost premium of 30 percent, said CEO David Johnson.

The company is seeking $25 million round to get validation of its multi-cylinder engine technology. The company previously raised $35 million from investors including Sequoia Capital, Rockport Capital Partners, Madrone Capital Partners and Gary Convis, vice chairman of Dana Corp. and former chairman of Toyota Motor North America.

Johnson said he has secured commitments from some existing investors but is searching for a a new lead for the round, expected to close by the third quarter.

The fuel efficiency gains are achieved, in part, because the two-stroke engine lacks a cylinder head, an engine component that loses 8 percent of energy as heat. Instead, there are two pistons, which offer twice the power density, in the engine, which is lighter and smaller than its competition, Johnson said.

The company is now launching testing of a four-cylinder engine with eight pistons using the same technology. The power-dense, lighter engine balances force and torque in its streamlined, symmetrical design. The technology is designed so that it can be used alongside batteries in hybrid engines.

Johnson said he expects increasingly stringent fuel economy standards to put the spotlight on diesel engines (see Hottest startups woo cleantech investors with wide-ranging tech). Problem is, he said, the U.S. doesn’t have the necessary manufacturing facilities because domestic demand favors gasoline engines.

“There’s not a single U.S.-based plant that makes diesel engines, except for commercial trucks, which is a field already driven by economics,” he said. “[Manufacturers] are going to change, so the question is: Will it be to regular diesel engines or Achates Power diesel engines?”

Achates plans to license its technology to engine manufacturers and vehicle makers for $50 million, plus a 5-percent royalty per unit.

“We plan to turn companies that would otherwise be competitors into our customers,” Johnson said.

The technology has applications in standard vehicle engines, as well as jet engines and unmanned military vehicles. Johnson estimated the global market at $235 billion, with about 90 percent addressable by Achates Power’s technology.

Achates Power is one of 15 potential new investment opportunities the Cleantech Group added to its dealflow database this week, available exclusively to members of the Cleantech Network. Members can click here to search the dealflow database.

Renewables and cleantech: picking a winner is still an uncertain ...

Renewables and cleantech: picking a winner is still an uncertain business 07 August 2009 When waste processing outfit Bioganix plc ran into funding trouble earlier this year it became the latest in a string of businesses to find itself on the compost heap.

Despite pumping several million pounds into designing and building plants that turn household waste into compost using anaerobic digestion technology, Bioganix struggled to get many local authorities to embrace the idea.

While a handful of customers agreed to deliver truck-loads of organic rubbish to the company’s industrial-size composters, most were taking far too long to make a decision – despite looming government rules forcing them to cut back on landfill. Those customers were simply not ready, it seemed, to start sorting out piles of rotting banana skins and last night’s vegetable curry.

The twist in the Bioganix story is that last month the UK government laid out plans for how it will reduce the country’s CO2 emissions by 34% on 1990 levels over the next 12 years. Five per cent, it declared, will be achieved by cutting emissions from agriculture, land use and waste – and a big part of that is support for anaerobic digestion.

Whether or not the new government backing would have changed things for Bioganix is a moot point. But in a wider context it emphasises the fact that while renewable energy and clean technology have emerged as hot topics for investors in recent years, picking a winner remains perilous. Not only are many companies developing technologies that may or may not prove to be the next big thing, entire industries can be made or killed off by the decisions of government.

Market uncertainty

In an interview with SmallCapNews.co.uk in January this year, Peter Linthwaite at CT Investment Partners, the investment arm of government-backed low carbon economy cheerleader, Carbon Trust, spelled out the problems faced by investors.

He said it was critical to be able to identify when the technology development and the market demand were coming together. “It is no use having a great piece of technology if the market is very conservative and companies are afraid to buy it because they are unsure whether or not it will work,” he said.

As a seasoned VC investor, Linthwaite’s investment approach towards infant companies in emerging market sectors echoes the lessons learned from mistakes made by other investors during the dotcom boom of the late nineties. While many argue that the tangible benefits of renewable and cleantech technologies companies are much easier to identify, others point to the fact that finding a company able to deliver long-term profits is a tricky business – and that makes investing in one of these businesses a particularly risky proposition.

A case in point is AIM and Nasdaq listed wave power specialist Ocean Power Technologies plc, which last month unveiled record losses – doubling in two years to $18.3m. Despite never making a profit, the company’s PowerBuoys, which generate electricity from waves, are in use in Hawaii, Spain and the UK and the company has some big defence customers, not least the US Navy.

More importantly for Ocean Power is the fact that key governments are making the right sounds about its technology. In its domestic market it has attracted US federal grants and is now piling more resources into making sure that its existing projects also get government support. In the UK, the government has earmarked up to £60m for wave and tidal energy projects, which includes up to £9.5m in the Wave Hub sub-sea socket off Cornwall, where Ocean Power is playing a key role.

It is a similar story at Tanfield Group plc, the British engineering group that makes electric vehicles. Last year it slumped to an £88.5 million loss because of the economic downturn following after three successive years of profits. Despite that, the company has received government funding support on both sides of the Atlantic. Indeed, this week it picked up US$10m from the US Department of Energy as a subsidy for private sector procurement of up to 100 electric vehicles.

While government support is underpinning interest in some sectors, others are being fuelled by mergers and acquisitions activity. Last month Solar Integrated Technologies plc, an American company that builds roofs with built-in solar panels, agreed to be taken over by Nasdaq-listed solar specialist Energy Conversion Devices. Energy Conversion’s £6.8m offer valued the company’s shares at 6.75p – close to its then trading price, but someway off its 90p per share value 12 months earlier. It appeared that shareholders had lost interest but a US group with an eye on the potential for solar power saw an opportunity.

It wasn’t the only one. In June, AIM-listed cleantech investor Low Carbon Accelerator Ltd increased its stake portfolio company Quantasol Ltd, investing £1.175m as part of an overall £1.975m funding round with Imperial Innovations. The move took Low Carbon’s investment in the company to £2.375 million for 41.4% of the equity. Quantasol is behind a third generation system of solar photovoltaic cells for use in concentrating photovoltaic systems.

Low Carbon’s shares have been on a rollercoaster during the last 12 months – starting at 50p last August, they have since dropped to 16.5p, jumped back to 50.5p, slumped to 18.5p and are now trading at around 30.4p.

Investment headache

While wild share price movements and feverish activity in the renewables and cleantech sectors has got some investors jumping for their wallets, others have been left rueing their misfortune. Just ask those that took a punt on Biofuels Corporation plc a few years back.

Biofuels was behind the construction of a massive biodiesel processing plant at Seal Sands in Middlebrough, which was officially opened by then Prime Minister Tony Blair in 2006. The company’s share price once hit 300p-plus before tumbling back down to 5p shortly before it self-combusted. Despite the good intentions, Biofuels never made a profit and was labouring under nearly £100m of debt before Barclays put it out of its misery.

Elsewhere and more recently US fuel cell developer PolyFuel Inc had its AIM shares suspended last month after failing to attract any more investment. Despite securing US$5m of grant aid from the US Department of Energy, the company behind energy saving laptop batteries was still scrambling for cash. Its shares endured a year-long decline from 10p to 4.4p, leaving it to claim that raising equity capital for AIM listed development stage companies was very difficult in the current economic environment. That was despite the fact that AIM companies raised a very healthy £1.4bn in secondary fundraising during the first half of 2009.

According to Niki Dixon, the head of technology at business advisory firm Grant Thornton, companies in the cleantech sector can still rouse the interest of investors despite a slowdown in the sector.

“Looking to the future, clean energy will become a crucial component of our global energy infrastructure and portfolio,” she said “Despite there being only a 5% growth in the sector between 2007 and 2008, where previously there had been a 56% level of growth between 2006 and 2007, interest from a range of investors remains strong.”

These views are reinforced by findings on the other side of the Atlantic which show that US venture capital investments in cleantech companies improved to $572m in the second quarter of 2009, up 73% over first quarter investment totals. Of note, however, is that while investors are showing a keener interest in the sector, the US venture capital numbers are still down on a year earlier.

Back in the UK, and Grant Thornton’s analysis indicates that despite the uncertainties of the renewables and cleantech markets, it is clear that a great deal of opportunity exists for running and investing in companies in the space. In particular, it reckons that UK businesses have the chance to exploit trends in the cleantech sector despite the economic slowdown.

Dixon said: “UK businesses have the opportunity to take advantage of new trends but must be ready to deal with global competition for investment.

“The UK government commitment to creating a low carbon economy will reinforce the appetite for investment in wind, biomass and waste to energy projects at home but UK business also has the expertise to benefit from the global focus on low carbon technologies such as carbon capture, energy efficient building technologies and energy storage and distribution.”

Meanwhile investors will be left pondering which of those sectors will offer the best gains. With markets widely expected to start settling down during 2010, and government support for renewables and cleantech companies beginning to build, there are bound to be some big winners and some equally big losers in the years ahead.

First US solar towers produce home electricity

Solar080609

The first U.S. solar "power towers" have produced electricity for commercial use, Scientific American reports.

The feat occurred yesterday in the Antelope Valley, north of Los Angeles on the edge of the Mojave Desert. Sunlight reflected off 24,000 silver mirrors was concentrated on two 150-foot-tall towers, producing steam that turned a turbine and generated electricity. The mini-plant can produce five megawatts, enough for full power to about 4,000 residential customers of Southern California Edison.

The demonstration project offers a blueprint for larger plants in California and New Mexico. Fourteen towers will be added to create a 46-megawatt plant (with 200,000 mirrors) capable of generating 90 gigawatt-hours of electricity over a year, according to the start-up firm behind the power plant.

Here's a video.

Three cheers for Nersa for Refit II

Last month’s column reflected on the sources and types of funding that are becoming available to promoters of businesses in the cleantech sector. This article reflects on the progress being made with the renewable-energy feed-in tariff (Refit) in South Africa.

The reason for offering further insights into this theme is that it is both topical and important – topical in that, late last month, the National Energy Regulator of South Africa (Nersa) announced the addition of six renewable-energy categories or subcategories to the list of the four existing qualifying categories of wind, small hydro, landfill gas and concentrating solar, as announced on March 31. Refit is important because its progress is a healthy indicator of a more progressive and responsible policy stance towards a low-carbon future.

The Refit progress reflects an important bifurcation point in our power generation history. It is a point at which we, as a country, have chosen to shift from sole focus on the end itself towards the importance of the means.

Renewable-energy sources are gaining momentum from both a stronger regulatory push, as a result of more progressive local legislation and global compacts, and the growing economic pull underpinned by changing market fundamentals. Even with the challenges of current price hikes and affordability, the drive from government, particularly Nersa and the Department of Energy (DoE) to ensure that South Africa is true to its local and international commitments, is admirable. But has the time truly come to harness the abundance of national renewable resources for a more integrated energy mix generated by independent power producers (IPPs)? Even the sceptics have to agree – certainly, it is looking promising. But it is not all plain sailing as yet.

Fresh off the press comes Nersa’s consultation paper for the public and interested parties on the addition of new renewable-technology categories for Refit’s second phase. The inclusion of solid biomass technologies provides a clear delineation between allowable renewable and nonallowable cogeneration feedstocks, whereby Refit qualification ensures that power generation technologies use feedstocks from 100% forest wood, disqualifying all mill waste and agricultural plants and residues. Similarly for biogas, all qualifying Refit technologies must use fuels derived from biological treatments of waste – anaerobic digestion and landfill gas.

Owing to economies of scale, Refit Phase II considers only building integrated and ground-mounted large-scale solar photovoltaic systems with a capacity greater than 1 MW. Refit Phase II also includes concentrating photovoltaics (CPV) with a capacity greater than 10 MW, mounted on a two-axis tracker on the ground, and concentrating solar power (CSP) without storage and CSP (central tower technology) with six hours of storage a day. Refit Phase II excludes wave energy, tidal energy and geothermal renewable technologies, labelling them noncommercial but for possible future consideration.

In addition to announcing the new additions to Refit, Nersa has also published, for public review and comment, the proposed draft power purchase agreement (PPA). From an investor’s perspective, the PPA terms are, quite simply, a crucial determinant. At first glance, the PPA seems to reflect an adequate starting point, having been modified from that used for the previous round of proposals requested by Eskom as part of its medium-term power purchase programme, in 2008.

Only detailed, rigorous review will reveal the intricacies of the commercial terms and the overall risk-return profiles for each renewable-energy category for developers and investors alike. In addition, in order to support the growing green electricity market, Nersa has also permitted IPPs to sell power directly to entities willing to buy renewable energy outside Refit, provided that a generation licence has been granted. No surprises here.

In summary, kudos are due to Nersa and to all those advocacy groups for the progressive, collaborative and constructive stakeholder engagements. Now all that is needed is further clarity on key variables, namely the size of each market by renewable-energy category, the Refit licensing process, fixed timelines and the bidding criteria, assuming that Refit will go the competitive bidding route. This column will keep you posted on these important developments.

Show Me the Money: Concentrating Solar Power Generation and ...

FOA: Baseload CSP Generation

The DOE’s Solar Energy Technologies Program ("SETP") entails applied research, development and deployment activities focused on achieving high penetration of solar power technologies across the United States and making electricity generated from the sun cost-competitive with conventional grid electricity. As part of the SETP’s CSP subprogram, this FOA is designed to investigate and accelerate the deployment of advanced solar technologies as alternative heat and energy sources, with the goal of positioning the United States as a leader in the area.

CSP technologies, which can be used in utility-scale power plants (100 MW or greater), are composed of three generic system architectures,1 all of which share two operational characteristics: (1) they concentrate energy from the sun and convert it to heat, and (2) they use the heat to drive a heat engine/generator to produce electrical power.

This FOA involves two topic areas:

Topic 1: Research and Development Concept and Component Feasibility Studies

Under this topic area, applicants are to propose projects involving research, evaluation and testing of concepts and components that will help achieve baseload CSP generation. This topic area focuses more on research to help advance CSP technologies. Successful applicants should demonstrate the potential to significantly reduce the cost of baseload CSP power.

Topic 2: Baseload CSP System Study

This topic area is aimed at development of a complete CSP system that meets baseload criteria. Applicants must have a specific CSP system approach in mind, for which they propose performing a feasibility analysis. Applicants should also identify potential engineering partners and developers that could team up on design, prototype building, testing and evaluation.

Projects under both of these FOAs will be carried out in three phases. After each phase, DOE will determine whether to fund the next phase. DOE expects to award approximately $15 million in FY 2010 and an additional $19.5-$37.5 million in FY 2011-2014. The deadline for submitting applications is October 15, 2009.

FOA: Community Renewable Energy Deployment

This FOA is designed to provide financial assistance to communities in order to facilitate the widespread deployment of renewable energy installations. The FOA is targeted at communities with existing renewable energy technology plans that can be implemented through swiftly deployable renewable energy installations.

Eligibility is limited to state and local governments, Indian tribes and Tribal Energy Resource Development organizations or groups; however, applicants are encouraged to partner with other state and local government agencies, utilities and renewable energy project developers. Applicants should be able to demonstrate how a comprehensive community energy strategy, adoption of codes and standards to support renewable energy and strategic partnerships can help facilitate large-scale renewable energy deployment.

Up to $21.45 million is available under this FOA, and the cost share must be at least 50 percent of the total allowable costs for demonstration and commercial application projects. DOE expects to issue one to four awards under this FOA. Applications are due on September 14, 2009.

______________________
1 The three system architectures are (1) line focus (trough and compact linear Fresnel reflector), (2) point focus central receiver systems (power towers) and (3) point focus distributed receiver systems (dish engines).

First US "Power Tower" Lights Up California

In southern California's Antelope Valley, 24,000 silver-bright mirrors have been positioned to reflect light on two 50-meter-tall towers. And at 11:08 A.M. local time Wednesday, this concentrated light heated steam in those towers to turn a turbine—the first "power towers" in the U.S. to convert the sun's heat into electricity for commercial use.

Dubbed Sierra SunTower, the power plant can produce five megawatts, enough to power roughly 4,000 local homes at full capacity—and provide the modular blueprint for larger plants in California and New Mexico, according to eSolar, the Pasadena start-up behind the power plant.

"We call this a commercial demonstration," says eSolar senior vice president of engineering Craig Tyner. "A 46-megawatt commercial design will incorporate 16 of these towers, two of which we have at Sierra" as well as more than 200,000 mirrors capable of generating at least 90 gigawatt-hours of electricity per year.

Harvesting the sun's energy as heat is hardly a new idea: During the energy crisis of the 1970s, designs for solar thermal power plants took off. And ever since 1984, vast arrays of curved mirrors have been concentrating the sun's rays on pipelines filled with synthetic oil at the Solar Energy Generating Systems (SEGS) power plant in California's Mojave Desert. But power towers, at least theoretically, would be more efficient than these so-called parabolic trough designs, because all the heating and fluid is contained in one central tower.

The key to eSolar's design are the mirrors—known as heliostats in the concentrating–solar power industry. By precisely calibrating the mirrors with computer algorithms driving shoe box–size motors, eSolar can build its sunlight-harvesting power plants with many more small, flat mirrors, roughly one square meter in size, as opposed to the large, curved specialty mirrors employed in other designs. "We're using more software algorithms and less steel," says Bill Gross, CEO of the Google-backed solar company who, at the age of 15 in 1973, started Solar Devices, a firm which sold plans and kits for solar power, before pioneering pay-to-click advertising for search engines in the 1990s.

But the multiplicity of mirrors could also prove the technology's weakest link. "The question is going to be the maintenance of all those heliostats," says Mark Mehos, program manager for concentrating solar power at the U.S. Department of Energy's National Renewable Energy Laboratory in Golden, Colo. "You have orders of magnitude more heliostats that you're going to have to maintain and that you're going to have to track."

Sierra SunTower has a number of environmental points in its favor in addition to the renewable energy it generates. It employs reclaimed water for its cooling and was built near existing transmission lines on what used to be farmland rather than the pristine desert areas nearby that have provoked opposition to some other planned solar power plants. "This model makes the destruction of public lands unjustified," says David Myers, executive director of nonprofit environmental group the Wildlands Conservancy. "There are 200,000 acres in southern California of lands that are degraded or disturbed that we support for solar electricity."

Gross, for his part, estimates that the entire state of California's peak electricity demand could be generated from an eSolar field of 65 square kilometers. That electricity would cost no more than 13 cents per kilowatt-hour, the current average price of power in the state, although the company refused to reveal how much the existing plant cost to build or what price Southern California Edison is paying for the power. "This is a second industrial revolution to power the planet cost-effectively from the sun," Gross says.
