摘要: The UK has an extensive gas system but studies of decarbonisation pathways using the MARKAL least-cost energy optimisation model have concluded that natural will be mostly abandoned by 2050 to achieve a 90% reduction in CO2 emissions relative 1990. In this study we examine possible future role system. Firstly, improve representation and add bio-methane hydrogen injection as options. Secondly, increase flexibility with addition biomass CCS technologies use industrial sector new Both contribute are insufficient alone avoid being reference scenario. However, model, for electricity generation or production, allows remove from atmosphere relaxes emission cuts other sectors economy. decarbonise processes is also strongly favoured model. With these technologies, continues dominate space water heating demand 2050; conversely, if plants prove uneconomic then almost certainly targets.
