Biohydrogen: A life cycle assessment and comparison with alternative low-carbon production routes in UK

This study focuses on the production of hydrogen from municipal solid waste (MSW) for applications in transportation. A life cycle assessment (LCA) was conducted a semi-commercial advanced gasification process Biohydrogen (Bio-H 2 ) MSW to evaluate its environmental impact five categories: Climate Change, Acidification, Eutrophication Fresh Water, Ecotoxicity Freshwater and Photochemical Ozone Formation (human health). The biogenic composition effect carbon sequestration were analysed Bio-H , uncovering net-negative process. counterfactual case incineration further bolsters savings associated . is proven be competitive against alternative productions routes, namely blue (Blue-H produced via steam methane reforming/autothermal reforming coupled with capture storage (CCS), green (Green-H solar offshore wind, respect climate change. These change advantages are shown carry forward context decarbonisation electricity grid mix, as by scenarios taken 2030 ‘net-zero’ 2050. • LCA applied Municipal Solid Waste gasification. pronounced negative footprint CCS. provides valid landfill incineration. outcompetes H routes impact. benefits future grid.
