Clean energy blues

A few items of interest about clean energy:

* Technology Review has a pretty balanced report on the German experiment in boosting solar power generation by generous "feed in" tariffs for your domestic solar cells. On the one hand:

The German grid now gets more than 16 percent of its electricity from these sources, and the government has raised its target for 2020 from 20 percent to 30 percent. The country avoided pumping about 74 million metric tons of carbon dioxide into the atmosphere in 2009. The German environment ministry also touts a side benefit: nearly 300,000 new jobs in clean power.

But on the other hand, some say:

..the German policy is a government boondoggle. "It's not surprising that if you throw enough money at a certain technology, people will use it," says Severin Borenstein, codirector of the Energy Institute at UC Berkeley's Haas School of Business. Yes, the incentives triggered a frenzy of renewable-power installations, but at "very high prices," says Henry Lee, director of the Environment and Natural Resources Program at Harvard's John F. Kennedy School of Government. The spending on photovoltaics has been especially cost-inefficient in terms of producing power, Lee adds, because "Germany is the cloudiest country in Europe." Despite the weather, Germany now accounts for half the world's 20 gigawatts of installed solar capacity. "What that gets you," says Lee, "is high prices for electricity, locked in for 20 years, from technology that will be out of date within three years." Concludes ­Borenstein: "That's a failure of public policy."

I do find it particularly odd that cloudy old (northern) Europe is the part of the world really going for solar. I remain sceptical of the wisdom of the program, although I presume it would all make more sense in places like the top half of Australia.

* Technology Review also has a long article about Zhengrong Shi, the Chinese businessman (but Australian citizen) and his hopes for improved solar cell efficiency in the not so distant future. Still no real talk in the article about how you store the electricity once the sun goes down, though.

* The 7.30 Report featured a story about an Australian company which is going off to Europe to build its ceramic fuel cells. These seem very promising, yet are getting little support from the Australian government because they run on natural gas. This seems pretty silly to me, especially if these claims are true:

Ceramic Fuel Cells claims its Blue Gen unit is much more efficient than the current power grid where up to 80 per cent of the energy can be lost in transmission and it says the unit produces two thirds less carbon dioxide emissions than coal fired generators.

Interestingly, the Greens think fuel cells should get feed in tariffs, and Senator Nick Xenophon points out that if the government is going to not pay feed in tariff for energy from natural gas, why do they pay renewable energy money on heat pump hot water systems, which run on electricity from coal? Fair point, and it certainly seems true that no single party has all the answers to sensible clean energy policy in Australia.

I first mentioned this Australian company here 2 years ago. Seems that they are moving slowing towards large scale production.
