This second webinar was held on Friday 25th April, for anyone who wasn't able to join us for the previous webinar held on Thursday 20th March. This webinar presented the findings of a study to assess the economic viability of natural gas combined-cycle power plants with CO2 capture and storage (NGCC-CCS) in climate change mitigation strategies, emphasising the use of renewable energy and natural gas for electric power generation. In this study, the cost of NGCC-CCS was compared on a level playing field to those of intermittent renewable energy systems (IRES) and energy storage technologies as a means of reducing power sector greenhouse gas emissions. Specifically, the levelised cost of electricity (LCOE) of NGCC-CCS was compared to that of offshore wind, photovoltaic systems, and concentrated solar power (CSP) together with pumped hydro storage (PHS), compressed air energy storage (CAES), and Li-ion, ZEBRA and Zn-Br battery storage systems. The cost of NGCC-CCS as a backup technology in conjunction with IRES also was assessed. At this webinar, Machteld van den Broek, senior researcher at the Utrecht University, presented the findings of the study. Her expertise is energy systems modelling and CCS. Among others, she is involved in the CATO-2 programme, the second Dutch national research programme on CCS. During the webinar Professor Edward Rubin from Carnegie Mellon University and co-author of this study, will assist during the Q&A session. Niels Berghout, from Utrecht University also contributed to this study.
