Green-hydrogen opportunities differ sharply from one market to another because production pathways, demand pools, regulation and international trade roles are evolving at different speeds. NTT DATA supported a global opportunity assessment to give strategic investors a common framework for comparing countries and technologies rather than relying on isolated national studies or headline capacity announcements. The assessment connected supply and demand with each country’s intended position in the emerging hydrogen economy. It examined whether markets were developing primarily as exporters, importers or domestic-demand centers, and placed that positioning alongside legal frameworks and national hydrogen strategies. This made it possible to view market attractiveness as a combination of economics, demand, policy and ecosystem maturity rather than as a single production-cost comparison.
A global hydrogen investment strategy has to normalize information that is fragmented across countries and often expressed through different policy targets, technology assumptions and market structures. The challenge was to create a comparable view without losing the country-specific factors that determine whether a market can become investable.




NTT DATA structured the work as a multi-dimensional market and technology assessment. A consistent set of strategic questions enabled cross-market comparison while preserving each country’s regulatory and market context.
NTT DATA combined market and technology perspectives within a single assessment framework.
Production routes and demand sources were considered alongside country positioning and policy conditions.
The principal green-hydrogen routes were evaluated in relation to the global opportunity landscape.
Major demand sources were analysed to identify where hydrogen adoption could create meaningful market pull.
Decision-makers gained better visibility of where production economics were supported by credible demand, how national strategies and legal frameworks could accelerate or constrain investment and which countries appeared better positioned for deeper commercial or technical evaluation. This kind of assessment improves the quality and repeatability of international portfolio decisions because markets can be compared through the same strategic dimensions rather than through disconnected country narratives. The reviewed reference does not publish a project-specific quantified improvement KPI; the Success Story therefore presents the documented decision-support value without inferring a financial return.
