CO2-Enhanced Oil Recovery For Decarbonization May 3, 2021 6:30:pm Summary In a future in which the energy system faces dual challenges – addressing carbon concerns and transitioning away from hydrocarbons altogether – reducing the carbon impact of fuels will become a key tool in meeting climate and energy goals. by: Colin Ward, OXFORD INSTITUTE FOR ENERGY STUDIES (OIES) Posted in: CO2-Enhanced Oil Recovery For Decarbonization As an example, jet fuel is very difficult to substitute due to the low energy density of batteries and the high cost of alternatives like hydrogen, making an upstream solution the only option until technology and costs evolve. Thus, making the best of the existing energy supply chain through decarbonization is a realistic and cost-effective option for the mid-term and warrants investigation.
