Techno-economics evaluation of electrolyser technologies: multicriteria decision making with SmartGridEval

The global landscape of hydrogen use has witnessed significant developments. Its high energy density and ability to be stored for an extended period make it an excellent fuel for storage systems. Green hydrogen, produced through renewable electricity, is identified as a crucial complement to optimising renewable energy production via the electrolysis process and provides several benefits to the power system, including avoiding network criticalities (e.g., overvoltages and overcurrents), using the excess energy during renewable energy sources peak generation time, enhanced distribution network hosting capacity, increased system flexibility, and improved system efficiency.
