Indirect gasification of residual biomass coupled with sorption-enhanced water-gas shift : A cost-effective platform for negative CO2 emissions and climate-positive hydrogen
Among options to deliver negative emissions cost-effectively, the coupling of sustainable bioenergy with CCS (BECCS) is particularly attractive. More specifically, biomass gasification with pre-combustion CCS allows for the production of H2 through the capture and sequestration of biogenic CO2. Thus, the term climate-positive H2 has been coined for a H2-rich fuel stream that has been created from sustainable residual biomass, produced by a system with a net reduction in atmospheric CO2 through the capture and sequestration of biogenic CO2. In this work, the indirect gasification of biobased residual streams (Milena) is combined with the efficient pre-combustion capture of CO2 from syngas by high-temperature adsorption (C-Shift) – two technologies that are steadily developing towards widespread commercial implementation and the combination of which creates an economically attractive route for climate-positive H2. The resulting technical and economic KPIs yield a cold gas efficiency of 64%, and a product yield of 91grammes of hydrogen per kilogram of demolition wood. While efficiency penalties arise from the compression needs for the transport and storage of CO2, the overall CO2 balance is very promising: for every kg of dry demolition wood processed, 1.3 kg of CO2 are effectively removed from the atmosphere. The CO2 price is a very important driver for the economy of the hydrogen production, as is the economy of scale. Accounting for market developments, and plants scaled-up to 150 MWLHV of biomass input, the production of hydrogen from biomass with CCS will have production costs down to 10 €/GJ or even below – close to or below the wholesale natural gas price in Western Europe
