Hydrogen from Wood Gasification with CCS - a Technoenvironmental Analysis of Production and Use as Transport Fuel

In the presented work, we performed an integrated techno-environmental assessment of hydrogen production from woody biomass gasification, combined with CO₂ capture and storage (CCS). We have included three different types of gasification technologies for syngas production. CO₂ is captured from the syngas with conventional amine-based technology. Based on our integrated approach linking detailed process simulation with Life Cycle Assessment, we are able to quantify benefits and potential trade-offs of a wide range of process configurations from both technical and environmental perspectives in a consistent way. We have also performed a comparative evaluation of hydrogen use in fuel cell electric vehicles (passenger cars and freight trucks), to investigate the role of hydrogen in decarbonizing the transport sector.
