摘要

Encouraging the adoption of sustainable energy sources and lowering the pollutants generated by fossil fuel use have emerged as crucial priorities for the international industrial sector. Sustainable clean hydrogen (green hydrogen), derived from sustainable energy resources (SERs), offers a favourable alternative energy carrier and storage when compared with conventional methods. This study performs an environmental evaluation of the life cycle (EE-LC) of a sustainable clean hydrogen (SCH2) producing process through the Water Electrolysis system (WES), provided with energy from SERs. The cases in which the use of wind and geothermal to make hydrogen is compared to the conventional steam methane method (known as Gray hydrogen). The Climate Warming Impact (CWI), which represents global warming and climate change, was evaluated via SimaPro software, considering both the materials used for construction and the running the project requirements of a 20 MW hydrogen-producing plan. The results show that wind energy results in the lowest CWI at 1.75 kg CO2/kg of H2, then the geothermal comes at 3.2 kg CO2/kg of H2, notably reduced compared to the transformation of steam methane into hydrogen that reaches 11.9 kg CO2/kg of H2. This research supports the use of the sustainable energy sources sector and the development of green hydrogen initiatives across various applications, advancing efforts aimed at reducing carbon emissions and fostering environmental responsibility.
