Comments Off on Power Barge Could Provide Affordable Wave Power

Wave power is an intriguing but difficult proposition. It offers a fairly steady source of power that is more regular than many other renewable power systems, but the marine environment is particularly harsh and difficult to work in. A number of wave power projects have struggled in the past few years, which shows how difficult this approach can be. A mobile wave power generating system proposed by Fraunhofer Center for Manufacturing Innovation would install wave generators along with banks of storage batteries onto ships or barges for portable wave power generation. The ship would go to sea and deploy its generators, and then return back to port and connect its batteries to the grid when it was fully charged. These ships would need to be outfitted with millions of dollars worth of storage batteries, and would have storage measured in megawatt-hours. One advantage an integrated power system incorporating this kind of vessel would have is that it could also serve as a grid-tied power storage system. If other renewable sources were producing additional power, there might be times when it would make more sense to keep the barges tied up at the dock and providing their storage capacity instead of sailing out to generate additional power. The basic premise for this has been around for a few years. Existing ships might be able to be repurposed for use as power stations, rather than requiring that new vessels be built. Additionally, while permanently installed wave power systems need to be robust enough to withstand the strongest storms, the mobility of the ship-based system would allow it to be moved back to safety in a harbor when severe weather threatened, which would allow for lighter weight construction. The cost of electricity generated in this way has been estimated to be as low as 15 cents per kilowatt-hour, as compared with 30 to 65 cents per kilowatt-hour with other wave power systems. There would also be considerably fewer regulatory hurdles that would have to be overcome since the generators would be vessels, rather than permanently installed structures. via: ecomagination

Comments Off on Renault to Build a Solar Roof Project a Big as 63 Football Fields

French car manufacturer, Renault, is about to start building the automotive world’s largest solar roof project that will eventually span the space of 63 football fields. The company is constructing the giant solar array in parts — pieces of the project will be located at six of its French plants — and will generate 60 megawatts of energy when completed. In total, the project will cut Renaults CO2 emissions by 30,000 tons a year.

Comments Off on Storing Renewable Energy in Boxes of Air

Storage is needed to harvest the full yield available from intermittent sources of energy like wind and solar. One of the options is compressed-air storage; till now only possible in underground caverns. But SustainX Energy Solutions; a Dartmouth College start-up  that got $4 million in VC funding from Polaris Venture Partners and Rockport Capital this year is working on compressing and storing air in cheap off-the-shelf shipping containers
