Decarbonisation of carbon-intensive industries (Iron and Steel Industries) through Power to gas and Oxy-fuel combustion

      From a carbon-neutrality and economic perspective, synthetic fuels should be targeted on industries that are inaccessible to direct electrification (e.g., steel, cement, glass, paper mills). The approach is to use these fuels in market niches that cannot decarbonize their processes by renewable electricity, either because CO2 is naturally produced from the chemical reactions during raw material processing or because the required operating temperatures are much easier to achieve through combustion than through electrification. In that sense, DISIPO project covers the design and analysis of the integration of synthetic natural gas in iron and steel industry, as competitive alternative against renewable electrification. Since the consumed synthetic fuel is produced again by Power to Gas from the industry’s emissions, carbon remains in a closed loop (synthetic fuels are recirculated to the industry itself or injected into the natural gas grid).

      The project presents a novel concept that combines Power to Gas (PtG energy storage) and oxy-fuel combustion (carbon capture) to decarbonise iron and steel industry. Power to Gas consumes renewable electricity to produce H2 (stored energy) and O2 (byproduct). This O2 is fed in the oxy-fuel furnace in the iron industry to attain a high concentrated CO2 stream, thus avoiding the energy penalization of requiring an air separation unit. Besides, the stored H2 and the captured CO2 are combined via methanation to produce synthetic natural gas to be used in the industry or distributed through the gas network. The overall objective of the project is to reach TRL 2 in the novel PtG–Oxy-fuel–Iron/Steel concept.

  • To design, simulate and optimize the integrated layout of the novel proposed concept, which combines Power to Gas with iron/steel industries operating in oxy-fuel combustion regime.

  • To assess the maximum feasible CO2 abatement under advanced control strategies adapted to the requirements of the iron/steel industry and the availability of the renewable energy resource.

  • To compare the proposed concept with iron/steel industries operating with conventional CCS (amine carbon capture and underground storage), under life-cycle analysis and economic assessment.
