A researcher at the International Institute for System Analysis in Austria named Marchetti argued for H 2 economy in an article titled "Why hydrogen" in 1979 based on proceeding 100 years of energy usage [7].The essay made predictions, which have been referenced in studies on the H 2 economy, that have remarkably held concerning the
Hydrogen can also be used for seasonal energy storage. Low-cost hydrogen is the precondition for putting these synergies into practice. • Electrolysers are scaling up quickly, from megawatt (MW)- to gigawatt (GW)-scale, as technology continues to evolve. Progress is gradual, with no radical breakthroughs expected. Electrolyser costs are projected to halve by 2040 to 2050,
