Carbon capture and storage (CCS) is an energy transition technology allowing the continued use of fossil fuels but removing the emissions from their combustion. Used properly CCS will enable high-energy industries and high emissions industries, time to develop low carbon alternatives to burning coal, oil or gas. However, capturing carbon and geostoring it is energy intensive and hence has a cost. First generation capture technology, retrofitted to conventional power stations from which CO₂ emerges as dilute, low-pressure flue gas pay a 30% energy penalty for the capture and burial of the CO₂. This penalty will reduce with new generation capture, especially when fitted to pre-combustion or oxy-fuel power stations and other industrial plants but it will never be zero – the second law of thermodynamics dictates that.
Currently, humanity captures and geostores about 36 million tonnes of CO₂ per year while it releases to the atmosphere about 36 thousand million tonnes per year. Geostorage of CO₂ is no more a technical challenge than producing petroleum and the petroleum industry has already demonstrated this in CO₂ enhanced oil recovery, a process that was first tried in Hungary back in the 1950s and which today sees millions of tonnes of CO₂ injected into oilfields each year.
The aim of this conference is to explore how best to develop large scale geostorage of CO₂. Prospective contributors should consider one or more of the following questions in preparation of their submission:
- How and where do we inject and store CO₂?
- How do we make sure and know the CO₂ stays in the ground?
- What needs to happen to create a substantial and sustainable CCS industry?
