Now this is an intriguing new technology from Germany’s ENERTRAG, via the WindSector blog — the hybrid power plant makes hydrogen from wind power to fuel automobiles! The techies among you will want to click through to see the technical drawings on how it works, but I’m hoping the economic development folks will get busy trying to figure out how we can get one going in Vermont, or at least somewhere in New England….
This is great news because now renewable energy will seem ‘real’ to the public. I’ve been in the workforce long enough to remember IBM’s entry into the personal computer market, which suddenly bestowed credibility on the product category previously occupied by others without household brand names. Here’s hoping the same phenomena happens with clean renewable energy — quickly.
Good news in renewable energy development this week. Minesto, a Swedish start-up and SAAB spin-off, looks to make a new tidal turbine commercially available within four years. Their “Deep Green” technology is a tidal stream system that uses the motion of the tides to generate electricity, similar to wind power generation. Deep Green’s turbines are connected to kites, which are anchored to the ocean floor, and move back and forth in the water to generate electricity (see an animation of this process here).
Minesto is optimistic about Deep Green’s eventual energy production capabilities (via CNN):
Anchoring “Deep Green” and steering the tethered “kite” enables the turbine to capture energy from the tidal currents at ten times the speed of the actual stream velocity…When operational, the turbine is expected to generate 500 kilowatts of power.

I’m fascinated by the possibilities for harnessing energy in new, clean ways. Unlike wind or solar, Deep Green Underwater Kites aren’t a market-ready renewable energy technology yet, but to me there’s hope in the possibility.
