Hydrogen is largely considered the best means by which to store energy coming from renewable andintermittent power sources such as wind and solar. With the growing capacity of out-spread renewableenergy sources surpassing the gigawatt range, a storage system of equal magnitude is required, suchas the production of electrolytic hydrogen by water electrolysis. Consequently, we envision a rapidmarket penetration of water electrolyzers in the next years. Nevertheless, the deployment of current,commercially available electrolyzer stacks and systems is conceivable for the current initial period ofenergy transition and shall go over the next decades. However, electrolyzers still need transformation,rupturing from small, costly and low-efficiency units into game-change electrolyzers much larger than10 MW, with efficiencies above 80%, power densities greater than 10 W/cm2, and demonstrateddurability above 100.000 hours. To achieve these goals, fast and large R&D investment is necessary,strong commitment from government and society; all tied with focused and intensive internationalcollaboration. Over the past 10 years, new companies and projects have appeared, with new leadersbeing consequently established in this growing “niche”. In this presentation I will show our latest R&Dapproaches; aiming to increase efficiency, improve durability, and reduce the investment/operatingcosts of electrolyzers to allow large market penetration of these systems. We believe that only throughcutting-edge R&D and significant advancements, we will be able to ultimately establish “green”hydrogen as a commodity in the energy storage market, and contribute to our so much desiredenvironmentally friendly hydrogen economy. |
