This combination of cheaper input energy and more efficient, cost-effective hardware is creating a powerful synergistic effect that is anticipated to propel the market growth over the forecast period.
MARKET CHALLENGES
High Capital Expenditure and Supply Chain Immaturity Challenge Widespread Deployment
Despite the promising growth trajectory, the AEM electrolyser market faces significant hurdles related to cost and supply chain readiness. The capital expenditure (CAPEX) for AEM systems, while potentially lower than some mature alternatives in the long term, remains high due to the nascent stage of manufacturing scale-up and the cost of critical materials. While alkaline and PEM electrolysers benefit from established supply chains, the specialized components for AEM systems, such as advanced anion exchange membranes and non-precious metal catalysts, are not yet produced at the gigawatt scale required for mass deployment. This immaturity leads to higher costs and potential bottlenecks. Scaling production from the current megawatt scale to the multi-gigawatt scale needed to meet global hydrogen ambitions requires massive investment in manufacturing infrastructure and a reliable, resilient supply chain for raw materials, which is still under development.
Other Challenges
