DESCRIPTION:Journal Club: Natural Gas\, Electrolysis\, Photocatalysis and M
 ethane Pyrolysis based Hydrogen Production in the UK a comparative life cy
 cle analysis of carbon emissions for future electricity and natural gas su
 pply scenarios\nThe Imperial Network of Excellence in Sustainability throu
 gh Life Cycle Approaches will host Louis Schilders \, who will present on
  his PhD work on hydrogen production in the UK. \nAbstract\nHydrogen can 
 decarbonise hard-to-abate sectors\, but its life-cycle climate performance
  depends on the production technology and the energy and feedstock systems
  in which it operates. This study presents an attributional cradle-to-gate
  life cycle assessment of seven hydrogen production routes under UK condit
 ions: alkaline\, proton exchange membrane and solid oxide electrolysis\; m
 ethane pyrolysis\; steam methane reforming (SMR)\; SMR with carbon capture
  and storage (SMR-CCS)\; and photocatalysis\, treated prospectively becaus
 e of its low technological readiness. SimaPro and ecoinvent were used to m
 odel 1 kg H₂. Scenarios varied UK electricity mixes for 2018\, 2025 and 
 2035 and 100% wind\; UK-market\, North Sea\, Norwegian and Russian gas sup
 plies\; production-stage methane leakage\; and component recycling. Global
  warming potential was assessed alongside ReCiPe midpoint impacts\, pertur
 bation sensitivity analysis and 1\,000-run Monte Carlo uncertainty analysi
 s. Results show context dependence. With North Sea gas and wind electricit
 y\, SMR-CCS produced 1.52–1.55 kg CO₂-eq/kg H₂\, compared with 1.70
 –1.87 for alkaline and proton exchange membrane electrolysis. Grid decar
 bonisation reduced 2035 electrolysis impacts to 3.40–4.32 kg CO₂-eq/kg
  H₂\, around 20–28% of 2018 values. Gas provenance changed SMR-CCS res
 ults by up to 4.65 kg CO₂-eq/kg H₂\, while higher methane leakage disp
 roportionately increased its footprint. Monte Carlo results confirmed SMR-
 CCS as lowest in the baseline case but showed overlapping uncertainty rang
 es among electrolyser technologies. Technology selection should be conditi
 onal on electricity carbon intensity\, gas provenance\, methane leakage an
 d capture performance\, rather than technology labels alone. Photocatalysi
 s remained infrastructure-dominated and recycling-sensitive\, requiring se
 parate interpretation as a prospective assessment.\n \nLouis Schilders is
  a 2nd year PhD student in Environmental Policy his interest is in hydrog
 en production technologies and life cycle analysis methods. His previous s
 tudies were at Durham University and LSE\, and he has work experience at L
 ongevity Partners (ESG) and the European Commission DG INTPA. \n \nPleas
 e note attendance to the Journal Clubs are limited to around 20 people to 
 ensure the quality of the discussions. If there are no open spaces you wil
 l be added to a waiting list and spaces allocated upon cancellations on a 
 first come basis.
