Synergies among electricity, gas and district heating in high RES worlds

21 November 2017 | EN | News

— Artelys is pleased to announce the publication by the ADEME of a follow-up study on a 100% RES power mix by 2050. This new study assesses how the gas and heat systems can be decarbonised in systems with high shares of renewable electricity generation.

The study relies on the Artelys Crystal Super Grid modelling platform, which has enabled us to represent the power system and its interaction with gas and heat vectors with an unprecedented level of detail thanks to its advanced features such as multi-energy modelling, investment planning, and ability to use high-performance computing infrastructure.

In fact, the study relies on the optimisation of the electricity mix (generation, storage, network) and of its ability to produce and inject synthetic natural gas (via electrolysis and subsequent methanation) and heat (via heat pumps and electric heaters) in gas and district heating networks. The investments and their management to ensure the power demand-supply equilibrium is met at all times are jointly optimised with an hourly time resolution over the whole year, using a spatial resolution where France is split in 21 regions.

The study shows that at the 2050 horizon in the context of a fully decarbonised power sector, the decarbonisation of the gas and heat sectors mainly depends on the CO2 price. For CO2 prices above 100 €/tonne, heat and hydrogen production become economically viable, and for CO2 prices above 300 €/tonne the production of synthetic natural gas from renewable electricity to replace fossil gas is found to be profitable.
