abstract = {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.},
