• Study finds California would meet net-zero targets more cheaply with CCS

A report released last month by the non-profit Energy Futures Initiative and Stanford University has found that deploying carbon capture and storage would allow the state of California to more economically achieve its goal of a carbon-neutral economy by 2045. Using CCS would provide about 15% of the state’s total emissions reductions, and in avoiding additional solar and battery storage installations would be around US$750 million (€633 million) cheaper than a non-CCS solution. One reason is that solar farms and battery storage would require more land than CCS installations, and another is the CCS-friendly federal tax credits currently available – the report estimates that capture and storage could turn a profit even today. The state has storage sites sufficient for 1000 years’ worth of emissions from its 76 largest COemitters at current rates of emissions, with activities such as ethanol and hydrogen production and oil and gas refineries being some of the most suitable to incorporate CCS. A key assumption in the report, however, was that the state would not use nuclear power, and its interesting conclusions must be seen in that context.
