Prospects for US Electricity Generation: Carbon Capture &/or Natural Gas


 David Gerard

Lawrence University

What will be the technology of the future for US electricity generation? Although  carbon capture and sequestration (CCS) has the potential for steep reductions in CO2 emissions, CCS faces many potential regulatory hurdles and public acceptance issues. Moreover, the technology is expensive – both in terms of additional capital costs and the additional fuel needed to capture, compress and transport the CO2.  I talk through some of my recently published work that assesses the decision to build new natural gas and coal-fired plants given future market and regulatory uncertainty, particularly uncertainty about future natural gas and carbon prices. I conclude that  CCS will not be commercially viable without beaucoup public financial support or outright mandates. I finish with some speculation on how the current fracking boom will affect energy and electricity markets. It appears that it will be natural gas all the way down as the principal source of new added generation capacity.
