New (Flow) Battery Design Could Help Solar and Wind Energy Power the Grid

22. Um… perhaps they want an actual clean technology

If you create fleets of natural gas fueled ICE cars, that’s what they’ll be.

If you “reform” natural gas and use the hydrogen in a FCEV it’s actually (somewhat) more efficient.

Then, you can “transition” to more and more renewable hydrogen.

When more wind power is available at the site than can be accepted by the network, a series of electrolysers are used to generate hydrogen which is stored on site. This stored energy, effectively acting as renewable base-load energy, is used in a number of ways:

. The hydrogen can be mixed with biogas and fed into cogeneration plants which produce electricity and heat. The electricity can then be fed back into the grid at times when little or no wind is available; the heat is fed into a district heating network, increasing the overall efficiency of the hybrid power plant.

. The hydrogen is also used as a fuel by TOTAL hydrogen refuelling stations in Berlin and Hamburg which support fleets of fuel cell vehicles.

Berlin Brandenburg Airport (BER) is also interested in using hydrogen from this project to fuel its vehicle fleet which is planned to be operational by June 2012.
