CSP is the most scalable and affordable baseload (or, even better, load-following) low-carbon supply technology — when used with low-cost, high-efficiency thermal storage. CSP can also share its steam turbine with biomass, a strategy the Chinese are pursuing, or with natural gas.
The Oil Drum wonders if Areva is “losing faith in the oft-predicted but unrealised ‘nuclear renaissance'." Certainly, Areva's best-known product has become very expensive and the cost of a new reactor today would be as much as 6 billion euros, or $8 billion, double the price offered to the Finns.
CSP, on the other hand, has just started down the experience curve and is poised to be one of the major winners in the low-carbon economy. Indeed, Bloomberg/BusinessWeek reports: Areva SA of France predicts the global use of solar-thermal power will grow by about 30-fold this decade, a forecast that spurred the world's largest maker of nuclear reactors to buy a California-based equipment maker.
The technology, which typically uses curved mirrors to focus sunlight to generate electricity, will be installed on plants with 20,000 megawatts of power potential by 2020, Anil Srivastava, Areva renewable energies executive vice president, said in an interview. That compares with about 625 megawatts today, according to Bloomberg New Energy Finance data.
