Chinese capital is finally flowing into the U.S. clean energy market. Chinese direct investment in the U.S. clean energy economy has grown from just $4 million annually in 2006 to over $260 million in 2011. That increase is attracting attention, and not all of it is positive.
[Last week] Third Way released a report concluding that U.S. private-sector investors are losing interest in investing at home due to the fickle American policy environment, leaving Chinese companies to fill the gap. The report's authors worry that increasing Chinese participation in the U.S. clean energy market will "dramatically hamper U.S. companies' ability to compete" and "slow economic growth and American leadership."
Rather than welcome Chinese direct investments as job-creating, there is a tendency here in the United States to take a zero-sum view and assume that Chinese enterprise successes in this country are not good for American competitiveness. Last month, when China's ENN Group announced plans to build a massive solar power R&D, manufacturing, and generation complex in Clark County Nevada, some U.S. commentators suggested that the ENN facility would force solar panel prices down even further and drive U.S. firms into bankruptcy.
When it comes to the U.S. clean energy market, Chinese companies must feel like they cannot catch a break.
Over the past few months, many voices in the United States—myself included—have called for stronger U.S. trade enforcement vis-à-vis China, particularly in clean energy manufacturing. It appears that in at least some cases, Chinese manufacturing companies may be breaking global trade rules. If that is true, then U.S. policymakers have to do a better job protecting American companies and making sure WTO-illegal trade behavior does not erode U.S. competitiveness in this sector.
Playing by the rules goes both ways, however. If Chinese companies are willing to come over to the U.S. market and compete on an equal playing field, we should welcome that with open arms, not with knee-jerk protectionism.
Chinese competition is not the problem. As long as the field is level, U.S. companies can handle the competition. And if we open up new clean energy opportunities here in the U.S., ideally that will give the Chinese companies that are willing to play by the rules a pathway for opting in to our rules-based system. If those companies are successful, that success will be a positive contributor to the U.S. market, and it may also help convince Chinese leaders that heavy government subsidization is not the best pathway forward toward Chinese clean energy success.
In reality, the real problem isn't that Chinese companies are investing too much in U.S. clean energy technologies. The real problem is that they are not investing enough.
The United States does not have a clear policy framework on foreign direct investment. That makes our market difficult to traverse, and that means that in many cases, the only Chinese firms that can succeed here are the well-connected state-owned enterprises who are much more interested in fossil fuels than clean energy.
Growth rates for Chinese clean energy investments in the United States only look impressive when viewed in isolation. When you compare those numbers to the numbers for fossil fuels, clean energy is still just a drop in the bucket. In 2011, for example, China invested just under $2 billion USD in American fossil fuel sectors. Most of those investments went toward U.S. shale gas assets. The $260 million that went toward clean energy projects pales in comparison.
If we want to accelerate the clean energy market, we need to do more to level that playing field for U.S. and Chinese investors alike.

Here’s a little more info on this from KMB48:
Now, Japan, which is putting full blast on renewable energy, has a lot of pumped hydro and is likely to see a similar trend occur. “Cheap solar power during afternoon peaks could double the number of pumped hydro cycles from one to two times per day” in Japan, KMB48 adds.
This is one of those rather hidden but huge benefits of large-scale solar power implementation.
Thank to the reader who passed this one on to me!

Two great bodies, Lawrence Berkeley National Laboratory and CalCEF, have teamed up to give battery production and development a big boost in California. Here’s the news release just a few minutes off the press:
SAN FRANCISCO and BERKELEY, Calif. – May 29, 2012 – CalCEF, which creates institutions and investment vehicles for the clean energy economy, and Lawrence Berkeley National Laboratory (Berkeley Lab) today announced a partnership to launch CalCharge, a consortium uniting California's emerging and established battery technology companies with critical academic and government resources. By bringing together the dozens of battery companies and institutions in California working on applications for consumer electronics batteries, electric/hybrid vehicle transportation and the electric grid, Berkeley Lab, CalCEF, along with other Bay Area academic institutions, aim to create a regional ecosystem for innovation in energy storage that will not only jumpstart a new era of battery technologies but also help ensure that U.S. companies succeed in this highly competitive environment.
"The next decade will be critical for this industry and this region," said Berkeley Lab Director Paul Alivisatos. "With our highly regarded battery scientists and state-of-the-art equipment at Berkeley Lab, the CalCharge consortium will be able to leverage these resources to enable the development of battery solutions for electric transportation and other clean energy applications in California."
CalCharge is a first-of-its-kind public-private partnership working to accelerate the timeline of energy storage commercialization and market adoption through technology assistance, workforce training and market education. Members will have access to Berkeley Lab's world-class scientific facilities and personnel, including testing and diagnostics equipment not available to many start-up companies. CalCharge offers a streamlined and more affordable channel for Cooperative Research and Development Agreements (CRADAs) and similar arrangements. These allow firms to access technical resources at the Lab, which will help scale battery innovations from the bench to the market.
"To broadly scale renewable energy requires tackling the challenges of energy storage, and no technical community is better suited to those challenges than California's battery engineers and scientists," said Dan Adler, CalCEF's president. "The companies and organizations that make up CalCharge will be central to forging a renewable energy future."
California has emerged as the epicenter of battery innovation in the U.S., with more than 30 startups and large companies concentrated in the Bay Area alone. The state has consistently led battery technology patent registrations, reaching 258 filings from 2008 to 2010—more than the next three leading states combined—according to the 2012 California Green Innovation Index, an annual economic filing published by Next 10. What's more, in 2011 venture capital investment in energy storage grew thirteen-fold over the previous year, making up 11 percent of the total VC investment in clean technology for the state.
"There's a lot of battery know-how in California, specifically the Bay Area, but technology startups need an ecosystem to thrive," said Venkat Srinivasan, head of Berkeley Lab's energy storage research program. "The Berkeley Lab battery program, long known for its deep expertise in solving the problems in advanced batteries, is ideally positioned to work with battery companies in the region. We look forward to building this ecosystem with CalCharge."
A thriving regional ecosystem for battery development requires contributions from diverse partners, including companies involved in advanced battery technology, customers who will use that technology, and research institutions that can offer expertise and equipment to accelerate development of new technology as well as an educated workforce pool—all supported by local governments that will provide the policies and incentives to foster a regional energy storage industry.
"We wanted to start CalCharge because we know that emerging energy storage companies are facing a complex market and major technical challenges," said Doug Davenport, development lead for energy storage at Berkeley Lab. "CalCEF is an ideal partner for us because they bring a focus on policy and markets that truly complements our science and technology orientation."
Cheaper and higher-performing batteries are critical to our nation's clean energy future—underscored by the White House's call for decreasing greenhouse gas (GHG) emissions and putting one million electric vehicles on the road by 2015. Nationwide efforts are also underway to modernize our antiquated electric grid for increased renewable energy integration and grid-scale batteries are an essential element. California has also made strides to support battery technology development this year. It adopted the world's first energy efficiency standards for battery chargers and enacted the second round of the Advanced Clean Car Rules, which targets a 34 percent reduction in GHG emissions from 2016 levels by 2025.
CalCEF and Berkeley Lab will be presenting the CalCharge launch at the Silicon Valley Energy Storage Symposium, Wednesday, May 30 at 9:40am. Please direct CalCharge membership inquiries to email@example.com
CalCEF works to promote the transition to a clean energy economy by creating institutions and investment vehicles that grow markets for clean energy technologies. CalCEF is a non-profit umbrella organization that pursues statewide and national agendas via two affiliated entities governed by separate boards of directors comprised of prominent policy makers, scientists, entrepreneurs, and financial professionals. CalCEF Innovations, a 501(c)(3), leads CalCEF's analysis and product development, designing real-world solutions—market strategies, business models, and public policies—that rapidly advance clean energy adoption. The California Clean Energy Fund, a 501(c) (4), executes and scales the CalCEF investment strategy via a fund-of-funds model, partnering with leading investment managers.

The fourth annual GEA International Geothermal Energy Showcase concluded Wednesday, May 23, in Washington DC. The conference featured countries and projects in 6 different regions of the world: Asia and the Pacific, Europe, Turkey, Latin America, the Caribbean, and East Africa. Presentations by corporate and country leaders, for many of the projects, were very similar, but a few had unique challenges. Ultimately, what started out with policy, charts, and graphs ended up with a human face and concerns in Nevis and East Africa. The showcase was well-organized, resulting in a virtually flawless program.
Keynote Speaker: Sen. Jeff Bingman
Sen Jeff Bingaman (D-NM), Chairman of the Senate Energy and Natural Resources Committee, provided the keynote address. Highlights of his speech were echoed throughout the presentations:
Geothermal Power Development Dates from the 60′s
The US began development of utility-scale geothermal in the 60's and has the most installed generating capacity at 3187 MW. When referring to geothermal, a distinction is made between uses for power generation and “direct usage” (as heat energy). China uses more geothermal energy than us, but primarily for heating, and it is only beginning to use geothermal for electrical generation. In association with the conference, an International Geothermal Overview was concurrently released. Worldwide, there are approximately 11 Gigawatts installed.
With limited growth in geothermal power in the US, the focus was on exportable technology. "One of the best aspects geothermal has to offer is that it is very exportable," remarked Halley Dickey, Director Geothermal Business Development, TAS Energy, headquartered in Houston, Tex. “We build the entire plant here in the U.S. and export it abroad.”
Different Types of “Geothermal”
The GEA website contains a tutorial that outlines the various technologies used to tap the Earth’s heat energy. As we drill deeper into the Earth’s crust anywhere, temperatures will rise. In some places, that heat is closer to the surface. If the heat is also associated with water, drilling will release steam that can be used for direct heating or in a Dry Steam Power Plant. Other locations will need to manipulate the energy to make it useable.
A Flash Power Plant separates steam from hot water. A binary power plant uses an organic Rankin cycle (like a heat pump) to use low heat energy sources. In some places, there is enough heat but no water to produce steam. Deep in the Earth the rock may be fractured and water injected. This is known as Enhanced Geothermal Systems (EGS). All of the above systems use deep wells that can be over 2 miles into the earth. These tap into the Earths natural heat. Useable temperatures may be from 150 deg F to 700 deg F.
Geothermal wells for heat pump systems are more shallow, in the range of 150 to 600 feet. These wells take advantage of the relatively constant “surface” temperatures of around 55 deg F (depending upon location) and the magic of heat pumps to heat and cool homes and businesses. The Earth’s surface temperatures would be more than 20 degrees less without the additional heating effect of the sun. To some extent, then, Geothermal heat pumps are like wind energy, an adaptation of solar radiation, but far more constant due to the thermal mass of the Earth.
Nevis and East Africa
While every project presents a unique situation, two were particularly interesting. As with many islands, Nevis must produce its electricity without the benefit of a substantial grid. Similar to many islands, that power is produced with diesel generators. At $0.37 per kWh (equiv) that power is costly and polluting. This conflicts with tourism, the island’s principal source of income that capitalizes on the island’s natural beauty and greenery.
Land and equipment is limited, but reliability is paramount for the primary electrical production plant. With a capacity factor that can reach 96%, geothermal is an excellent option. With steam venting here at 485 deg F, this is a potent resource. Peak load is about 8.5 MW with a resource potential of up to 150 MW.
East Africa has many natural resources, including geothermal energy potential. There are hydroelectric plants, but these are actually unreliable with the extended dry periods. Economics and land use are significant concerns. Geothermal collects a concentrated energy source when compared to solar or wind. The land use is therefore much less. When enough land is set aside for geothermal, as it was in Kenya 30 years ago, it can support multiple uses. As if to proclaim the cleanliness of geothermal energy, Kenya’s first geothermal power plant is now located in the middle of a nature preserve.
But East Africa also needs employment. Electrification can support higher technology and a better standard of living, but employment is addressed with direct geothermal projects that use the heat and humidity in greenhouses and fish farms.
An Issue of Pollution
Prior to the showcase, I added to the comments section in another CT article that suggested that geothermal in Hawaii was not a workable plan. At a media roundtable, I was able to ask about emissions from some geothermal power plants.
First, we have to keep in mind that geothermal is an improvement over diesel generation. On islands like Nevis and Hawaii, where there is not a large grid, baseload power may be required and geothermal fits that description. An older plant like PVG may not be as adaptable as new construction, but the technology exists to capture emissions and, in some cases, turn chemicals into marketable products for industry. In the US, geothermal plants are required to contain emissions. At the roundtable I was offered and hope to yet receive the GEA’s response to complaints like these. Look for further updates.
Into the Future
Geothermal energy can be adapted to produce electricity in a number of ways. It can also condition our environments and provide jobs. Worldwide, there is enough easily obtainable geothermal energy to satisfy all of our electrical energy demands. In choosing geothermal, we take advantage of a more concentrated type of clean alternative energy with a smaller footprint. Geothermal is an exportable technology that can also be used to generate not only electricity but jobs around the world.

Developed at the request of Credit Suisse, EPFL researchers created the Power Monitor System and Management (PMSM) to monitor and track the power consumption of a data center. More than that, however, the PMSM also has the capacity to distribute the workload among several servers, and vice versa: “Two servers running at 40% of their capacity each, consume much more than only one at 80%” explained David Atienza, director of the Embedded Systems Laboratory (ESL), where the program was created.
According to David Atienza the PMSM can achieve energy savings “of at least 30%, and even up to 50% less of what is consumed today.”
The PMSM has already been installed on the racks of approximately 5200 servers in Credit Suisse’s data center in Zurich. According to Marcel Ledergerber, responsible for the management of this complex, the solution proposed by the ESL laboratory is particularly attractive to them since it contributes to a process of “server virtualization” that the bank has been undergoing for some years already. Such a process aims at progressively reducing the number of servers hosting a gradually greater computing power. “The PMSM system allows us to concentrate our machines in a smaller space,” he said. “The specific information that it provides allows us to better control the issues of temperature, and thus manage our installations more safely.”
