Solar’s New Competitor

Last week, Kate Galbraith wrote an article in the New York Times with the headline A Competitor Emerges for Solar Panels, which is  somewhat nonsensical.

It’s about the small co-heat and power (C.H.P) electric generator and hot water systems available for residential homes. This technology is not just emerging. I wrote an article about these five or six years ago when they were first marketed in Japan.

The article suggests that you can sell your excess power back to the grid (which I could not confirm), like is done with solar panels, and I suspect that is why she thinks they compete with solar, but solar panels “generate” zero emission renewable energy. These C.H.P units “consume” a non-renewable GHG emitting fossil fuel. Cogeneration competes with other energy consuming devices like 95% efficient condensing forced air gas furnaces and heat pumps. It’s an apples to orange comparison when it comes to solar.

Soliciting Reader Input for Bioenergy Chapter

9/8 Update: Lichtblick/VW announcement is now in the English version of Der Spiegel: A Power Station in Your Basement Green-energy provider Lichtblick and German automaker Volkswagen are joining forces and promising to stir up the energy market with an unusual plan. Instead of relying on massive energy facilities, the average consumer may soon have a miniature power station in their basement. Chief executives of Germany’s major energy suppliers usually don’t have much time for their junior counterpart, Lichtblick. The Hamburg-based green-electricity provider’s half a million customers may be “impressive,” they say, but Lichtblick works in a niche market and is no competition for the larger companies in the industry. The ambitious new project could be worth billions of euros and… Continue»

Wood Gasification Plant Opens

Been really tied up, but saw this story yesterday and wanted to bring attention to it. I think it is significant, and a sign of things to come. Not much time to comment, but some excerpts from the article: Plant making gas from wood opens in Austria GUESSING, Austria (AFP) – A new plant that produces gas from wood was opened in Austria on Wednesday, paving the way towards new possibilities in renewable energy. According to its backers, the gas produced at the plant can be used in urban heating systems, for gas-powered cars or by power stations that work on gas. “The gas produced has the same quality as natural gas,” said Richard Zweiler, from the European Centre for… Continue»
