In the SER (sorption enhanced reforming) gasification process a nitrogen-free, high calorific product gas can be produced. In addition, due to low gasification temperatures of 600–750 °C and the use of limestone as bed material, in-situ CO2 capture is possible, leading to a hydrogen-rich and carbon-lean product gas. In this paper, results from a bubbling fluidised bed gasification model are compared to results of process demonstration tests in a 200 kWth pilot plant. Based upon that, a concept for the hydrogen production via biomass SER gasification is studied in terms of efficiency and feasibility. Capital and operational expenditures as well as hydrogen production costs are calculated in a techno-economic assessment study. Furthermore, market framework conditions are discussed under which an economic hydrogen production via SER gasification is possible. •A concept for the production of hydrogen via SER biomass gasification is presented.•By using experimental data and a process model, the efficiency was calculated.•Based on the results, net production costs of 9€.kgH2−1 were calculated.•Cost factors & uncertainties were identified to assess cost reduction potentials.•In comparison to alternative technologies, this process is a competitive technology.
