Life cycle assessment of the natural gas supply chain and power generation options with CO2 capture and storage: Assessment of Qatar natural gas production, LNG transport and power generation in the UK

Abstract Fossil fuel-based power generation technologies with and without CO 2  capture offer a number of alternatives, which involve different fuel production and supply, power generation and capture routes with varied energy consumption rates and subsequent environmental impacts. The holistic perspective offered by Life Cycle Assessment (LCA) can help decision makers to quantify the trade-offs inherent in any change to the fuel supply and power production systems and ensure that a reduction in greenhouse gas (GHG) emissions does not result in increases in other environmental impacts. Beside energy and non-energy related GHG releases, LCA also tracks various other environmental emissions, such as solid wastes, toxic substances and common air pollutants, as well as the consumption of resources, such as water, minerals and land use. In this respect, the dynamic LCA model developed at Imperial College incorporates fossil fuel production, transportation, power generation, CO 2  capture, CO 2  conditioning, p...
