""Right now natural gas wins that race (for cheap power,)" Dinkel says. "The challenge is no one knows what those economics look like in five years.""
No one knows what those economics will look like tomorrow. Most utilities buy natural gas futures several months or years in advance. The problem with commodities, they may go down after buying and the contracts signed. The difference will be born by the ratepayers. This technology CSP with salt storage does not have to rely on commodity products to generate power. The question is, how long does the special oil last and the heat storage salt? If both products will last the lifetime of the plant, then getting away from a commodity like natural gas would cost less in the long term.
