The offshore carbon capture and storage (CCS) projects of Norway’s Sleipner and Snøhvit are often cited as good case studies for the viability of the technology. Other CCS hubs are being proposed from Malaysia to the North Sea to the Gulf of Mexico, larger by factors of 10 or more. But how viable are they? Grant Hauber at IEEFA summarises his in-depth report on the risks. Both Sleipner and Snøhvit, operating since 1996 and 2008 respectively, have … [Read more...]
CCS: Identifying the best underground locations for storing CO2 can take 10 years, so let’s start now
Underground geological formations have more space to store CO2 than we’ll ever need, by orders of magnitude. But the process of assessing the best locations can take up to ten years, so that work needs to start now, say Raimund Malischek and Samantha McCulloch at the IEA. The main constraints are technical (which porous rock formations absorb CO2 most easily, etc.), while the displacement of land use and public acceptance must also be considered. … [Read more...]
A pathway for profitable CCS in California
A study from the energy departments of Stanford University, from where Kara Glenwright writes, lays out a pathway for California to capture and store up to 60 Mt (million tonnes) of CO2 a year. 76 site locations have been identified where work could start immediately to store 20 Mt/yr profitably under the existing low carbon rules. But first a raft of clarifications on the laws is needed, showing that the success of CCS doesn’t just depend on the … [Read more...]
UK fracking earthquakes: why the world’s “toughest” safety rules failed to predict them
In August this year Lancashire experienced the largest fracking-induced earthquake recorded in the UK. Fracking was suspended. Legislators discussed a complete ban. As a result, serious questions are being asked about the effectiveness of the safety regulations, given the operating company, Cuadrilla, predicted there was a “low-likelihood” of such events occurring. And given the UK’s “traffic light system” (TLS) is the most stringent TLS in the … [Read more...]
