Local concerns about the safety of carbon sequestration are blocking European power giant Vattenfall’s plan to close the loop on greenhouse gas emissions from its coal-fired carbon capture and storage (CCS) pilot plant in Schwarze Pumpe, Germany. The ‘oxyfuel’ plant has been burning coal in pure oxygen since starting up last fall, making its CO2 exhaust easy to capture. But burial of the CO2, set to begin this spring, is now on hold according to the U.K.’s Guardian newspaper. Staffan Gortz, Vattenfall’s CCS spokesperson, told the paper that, “people are very, very skeptical.” Continue reading “Schwarze Pumpe Hits a Bump”
Europe Shortlists Capture Projects for Stimulus
European leaders shortlisted a dozen proposals to demonstrate large-scale carbon capture and storage at coal-fired power plants last month as eligible to share €900 million of the EU’s €5-billion stimulus funding package. The goal is to bring down the cost of carbon-neutral coal power — which the European Commission expects to continue to exceed the cost of conventional coal power in 2020 — and to gain more experience with underground storage of CO2.
Seven propose to capture CO2 post-combustion from the exhaust of conventional coal-fired power plants, a relatively inefficient process that nonetheless costs less up front — an attractive feature given today’s financial mess. Three are Integrated Combined Cycle Gasification or IGCC power plants that would pull CO2 out of coal-derived gases prior to combustion, akin to the U.S. FutureGen project that Bush killed and Obama may be reviving. Two more would concentrate their CO2 exhaust by burning coal in purified oxygen — the oxyfuel approach that Sweden’s Vattenfall is testing at a pilot plant in Germany.
