The world’s global coal-fired power generation plants provides around 40% of the world’s electricity. This fleet is the youngest it has been for decades, with more than 500 GW added since 2010, mostly in emerging economies. To simply shut these new and in many cases highly efficient plants down to meet climate goals would be a political, social and economic challenge. According to the IEA retrofitting these plants with carbon capture and sequestration (CCS) will need to be a key strategy in many regions.
There are now 17 large-scale CCS projects operating around the world, with at least one more due to be commissioned this year. China has just announced construction of its first large-scale CCS project in the coal-chemicals sector and with seven further projects under early development. The Petra Nova project in Texas was delivered on time and on budget earlier this year. Petra Nova is the second, and much larger, project to retrofit post-combustion CCS technology to an existing coal-fired power station, with costs reportedly around 20% lower than the world-first effort at Boundary Dam in Canada. On the other hand work on the most ambitious carbon capture and storage (CCS) plant in the world at the Kemper County Energy Facility in MIssissippi has been suspended. It turned out that the rapid scale up of a new integrated gasification combined cycle (IGCC) technology from pilot to a 585 MW plant proved to be far more complex and challenging than anticipated.
