Biohydrogen produced from biogas combined with carbon dioxide removal (CDR) can provide renewable energy whilst generating negative emissions. This study evaluates production costs and climate impacts of biogas-based hydrogen via steam methane reforming (SMR), electrified SMR (e-SMR), and plasma methane pyrolysis (PMP), together with CDR based on either CO₂ or solid carbon, across three production scales.
