Introduction
2024 was a very eventful year for the hydrogen electrolyzer market, a year undeniably headlined by( 1) news of high-profile hydrogen project cancellations,( 2) premonitions of the impending consolidation of electrolyzer manufacturer businesses( amidst a widely reported state of production overcapacity), and( 3) political winds of change that have reinvigorated debate on the green energy transition itself.
In response, some have declared such market developments to be entirely expected – consequences of an inevitable maturation phase for the hydrogen industry. Readily infused with Darwinian language of the‘ survival of the fittest’, 2025 is commonly regarded as a year where there is now a laser focus on not only commercial deployments( hydrogen projects are still moving forward, and new orders for 2025 are being declared) but also the supporting commercial strategies and financial residence of hydrogen electrolyzer vendors across the board.
