This city’s fast becoming Europe’s go-to spot for green hydrogen production, riding high on the EU’s Hydrogen Strategy and a flood of support from Berlin’s Senate Department for Economic Affairs. Industry forecasts predict green hydrogen production will attract billions in investments by 2030, and game-changers like the MoO2/Ni catalyst could be the tipping point in slashing system costs. And in remote communities, pairing solar fields with electrolyzers to store summer energy as hydrogen for winter use could be a real game-changer. With plasma-treated catalysts like MoO2/Ni cutting precious-metal requirements by over half, those numbers suddenly don’t seem so daunting. I won’t sugarcoat it: scaling green hydrogen production is a marathon, not a sprint.
