Assessing the prospective environmental performance of hydrogen from high-temperature electrolysis coupled with concentrated solar power

Hydrogen is currently being promoted because of its advantages as an energy vector, potential to decarbonise the economy, and strategical implications in terms security. from high-temperature electrolysis coupled with concentrated solar power (CSP) especially interesting since it enhances last two aspects could benefit significant technological progress coming years. However, there a lack studies assessing future environmental performance. This work fills this gap by carrying out prospective life cycle assessment based on expected values key performance parameters 2030. The results show that parabolic trough CSP solid oxide electrolyser promising solution under aspects. It leads hydrogen carbon footprint (1.85 kg CO2 eq/kg H2) which be classified low-carbon according current standards. benchmarking study for year 2030 shows assessed system significantly decreases compared steam methane reforming (81% reduction) grid (51%), even considerable penetration renewable sources.
