Energy Storage Rumors: Deeya Raises a Round; Bloom Piles Up Customers

Michael Kanellos: April 27, 2009, 8:15 PM

Energy storage: It's everyone's favorite topic these days. Renewable power technologies like solar and wind can't be optimized without storage. Unfortunately, rigging up massive lithium-ion battery packs at wind farms would be prohibitively expensive so everyone is looking at alternatives.

And flow batteries are just one of those alternatives. Deeya Energy, one of the few companies that specializes in this area, has closed up another round of funding, according to sources. The company raised $15 million in January 2008 in a B round. The company's L-cells are supposed to cost 10 to 20 times less than lithium-ion batteries. A flow battery sounds sort of like what it does. Electrolyte...

ETV Confirms Quercus Investment From a Few Months Ago

Michael Kanellos: April 27, 2009, 7:47 PM

ETV Motors, an Israeli company that has an electronic propulsion system, confirmed a $12 million dollar first round of funding today.

Although formally announced today, Quercus put money into ETV back in January along with 21Ventures, which tends to invest alongside Quercus. At last count, Quercus had invested in 47 companies, but some have hit some rough sledding. Ondyne, which makes propulsion systems for buses, called it quits in January. Entech Solar, meanwhile, announced layoffs last month. Entech makes solar thermal/PV devices, an interesting twist on solar. Others, however, are jumping into this market.

Like a lot of Quercus companies, ETV is sort of in the science experiment...

SV Solar, R.I.P.?

Eric Wesoff: April 27, 2009, 4:43 PM

The long list of VC-funded solar startups is starting to shrink.  We crossed Optisolar off the list, a victim of hubris (see Inside OptiSolar's Grand Ambitions) and it looks like SV Solar is soon to be history -- a victim of a poorly hatched business plan by neophyte staff and investors who should have known better.

SV Solar received $10.2 million in funding two years ago from partners at Bessemer with scant solar experience. The company funded a low-concentration PV firm (strike one), with a staff that had very little solar experience (strike two), based on some amazing cutting edge technology that they called -- a prism (strike 3).

Tough getting IP protection on a prism, I imagine.


Masdar City Lines Up Green Concrete Developer

Ucilia Wang: April 27, 2009, 4:42 PM

Abu Dhabi plans to work with Al Falah Ready Mix to develop low-carbon concrete for building what the government said will be a carbon-neutral city that would powered by renewable energy and built with cutting-edge green technologies.

Abu Dhabi, part of the United Arab Emirates, began building Masdar City last year, and expects to complete it by 2016. When completed, the 6.5-square-kilometer city could be home to 40,000 people and a host of greentech companies, Masdar officials have said. Masdar already has picked Suntech Power and First Solar to build a 10-megawatt solar farm, which will initially power construction activities. The developer plans to build about 240 megawatts worth...

NRDC’s Renewable Map Links Energy, Renewable Resources

Jeff St. John: April 27, 2009, 3:01 PM

The Natural Resources Defense Council has yet another map showing the connection between natural resources — sunshine, wind, crops and livestock — and the renewable energy potential attached to them.

The map on NRDC's Renewable Energy for America site color-codes the nation according to regional resources and shows the sites of existing and planned wind, biofuel and biodigester plants. Viewers can click on individual states for close-up views.

NRDC also has picked five states — Florida, Nebraska, Ohio, Pennsylvania and Tennessee — to highlight as "battlegrounds in the debate about what sort of action our country should take to stop global warming," according to a Monday blog post by...

Conergy to Sue MEMC to End Silicon Contract

Ucilia Wang: April 27, 2009, 2:42 PM

Conergy said Monday it plans to sue MEMC Electronic Materials to end a 10-year contract for buying silicon wafers, the materials for making solar cells.

Germany-based Conergy, which makes solar cells and assembles them into panels, said efforts to renegotiate the contract and get better terms failed. As a result, it intends to file suit in New York City and ask a judge to invalidate the contract.

The negotiation to amend the contract began earlier this year. MEMC, based in St. Peters, Mo., said last week that the contract talk stalled, and that it didn’t expect to sign a modified contract. MEMC posted $214 million in sales for the first quarter, down nearly 50 percent from the same...
