Tackling long-term climate change together: The case of flexible CCS and fluctuating renewable energy

Prospects of carbon capture and storage (CCS) in China’s power sector – An integrated assessment

“…Furthermore, the role of CCS in the electricity sector needs to be assessed with models with a high time resolution in order to account for the difference between CCS and stochastic renewables in terms of power supply security and stability. First of all, work on the flexible operation of CCS power plants [108,109] should be extended to obtain a complete picture of the possible role played by CCS in an integrated energy system.…”

The multi-period optimisation of an amine-based CO2 capture process integrated with a super-critical coal-fired power station for flexible operation

“…Given the increasing penetration of intermittent renewable electricity generation and the essentially inflexible nature of baseload nuclear power generation, there is increasing focus on the need for decarbonised fossil fuel-fired power stations to operate in a flexible fashion as part of the low carbon energy system of the future (Mac Davison, 2011;Ludig et al, 2011;Kalinin et al, 2012;Nimtz and Krautz, 2013;Domenichini et al, 2013;Oates et al, 2014;van der Wijk et al, 2014;Boot-Handford et al, 2014). It will be important that the flexible operation does not result in an increase in the overall carbon intensity of the electricity generated.…”

Optimizing post-combustion CO2 capture in response to volatile electricity prices

“…Least-cost dispatch modeling has demonstrated CO 2 capture as a base and intermediate load technology in a carbon constrained electricity system (Johnson and Keith, 2004;Luckow et al, 2010;Ludig et al, 2010;Wise and Dooley, 2009). These models enable detailed technology comparisons over long-term market conditions, but they do not represent short-term price volatility and intertemporal plant operating constraints needed to study flexible CO 2 capture.…”

“…Most studies assume that CO 2 capture and compression systems operate continuously whenever the base plant operates, so any energy required for CO 2 capture and compression permanently reduces output and increases electricity production costs (Davison, 2007;Rubin et al, 2007). However, there is a growing attention to the value of operating some or all CO 2 capture systems at partial or zero load and utilizing this flexibility to operate CO 2 capture in response to variable electricity market conditions (Chalmers et al, 2009(Chalmers et al, , 2010Husebye et al, 2010;Ludig et al, 2010).…”
