Limited availability of long-duration energy storage and green hydrogen transport infrastructure also complicates project bankability for developers in regions lacking existing pipeline or shipping access. Because large-scale project permitting and renewable interconnection cycles can take several years, some developers continue favoring smaller, modular electrolyzer deployments over gigawatt-scale greenfield investment.

Opportunities: Green Ammonia Export Growth and Industrial Hub Development

Growing international demand for green ammonia and green methanol as hydrogen carriers represents a significant opportunity, as shipping and power-generation customers increasingly seek certified low-carbon fuel alternatives. Developers positioned early in export-oriented production hubs stand to capture meaningful share as global green hydrogen trade continues expanding through the forecast period.

Expansion of dedicated industrial hydrogen hubs, combining electrolyzer capacity with co-located refining, chemicals and steel offtake, offers a second opportunity for developers able to secure long-term offtake agreements.
