A new report from Pike Research of Colorado says the addition of carbon capture systems to power plants will add 50% to 70% to the cost of creating electricity for existing and future plants.

The report, titled “Carbon Capture and Sequestration: Drivers and Barriers, Technology Issues, Key Industry Players, Market Analysis and Forecasts,” adds that such increases in costs will be initially underwritten by governments but gradually passed on to ratepayers.

U.S. researchers have demonstrated a technology that uses the sun’s heat to convert carbon dioxide and water into the building blocks of traditional fuels, a reverse combustion process that may emerge as a practical alternative to sequestration of CO2 emissions from power plants.

The prototype “Sunshine to Petrol” system, developed by Sandia National Laboratories in New Mexico, uses concentrated solar energy to trigger a thermo-chemical reaction in an iron-rich composite located inside a two-sided cylindrical chamber.

The iron oxide is designed to lose an oxygen molecule when exposed to 1,500 degree C heat, and then retrieve an oxygen molecule when it is cooled down, essentially converting an incoming supply of CO2 into an outgoing stream of carbon monoxide.
