“Clean fuel made by splitting water with clean electricity.” Green hydrogen is hydrogen gas produced through electrolysis powered by renewable energy — emitting no carbon dioxide in the process.
Executive Summary
Green hydrogen has attracted enormous policy enthusiasm as a potential solution for decarbonizing industries that cannot easily electrify — steel, cement, shipping, aviation, and long-haul freight. Unlike “grey” hydrogen (made from natural gas with high emissions) or “blue” hydrogen (natural gas with carbon capture), green hydrogen carries no direct carbon footprint. But as of 2025, the reality is sobering: production costs remain two to four times higher than grey hydrogen, scaling has been far slower than projected, and the geopolitical map of future green hydrogen trade is starting to resemble the dependency structures of the fossil fuel era.
The Strategic Mechanism
- Electrolysis basics: An electrolyzer uses electricity to split water (H₂O) into hydrogen and oxygen. The process is carbon-free only when the electricity input is from renewable sources (solar, wind, hydro).
- The cost curve: Green hydrogen cost is primarily driven by electricity price and electrolyzer capital cost. The target for commercial viability is approximately $1–2/kg; current global average production cost is $3–6/kg, though leading projects in sun-rich locations approach $2/kg.
- Transport challenge: Hydrogen has low energy density by volume, requiring compression, liquefaction, or conversion to ammonia for transport — each step adding cost and energy loss.
- New trade geography: Belfer Center analysis indicates future green hydrogen trade will concentrate in countries with abundant cheap renewables and water — Australia, Morocco, Chile, Oman — creating new energy export champions and new importers (Europe, Japan, South Korea).
- Policy scaffolding: The EU Hydrogen Bank, Germany’s H2Global program, and U.S. Inflation Reduction Act hydrogen production tax credits are the primary demand-creation mechanisms globally.
Market & Policy Impact
- As of 2025, the global green hydrogen market remains in a pilot-project phase, dominated by sovereign wealth fund-backed initiatives in the Gulf and state-backed programs in Europe and Australia.
- Germany has established bilateral hydrogen partnerships with over 20 countries — including Namibia, Morocco, Brazil, and South Africa — positioning itself as the anchor importer for a new green hydrogen supply chain.
- Japan and South Korea have signed hydrogen import agreements with Australia, with liquefied hydrogen and ammonia carrier infrastructure under active development.
- Green hydrogen creates new geopolitical dependencies that mirror oil’s structural logic: resource-poor industrialized importers will become strategically dependent on a small number of renewable-resource-rich exporters.
- Projects in politically unstable or poorly governed countries have struggled to attract private financing, limiting green colonialism fears but also constraining the Global South’s export revenue opportunities.
Modern Case Study: Morocco’s Green Hydrogen Ambitions (2024–2026)
Morocco has positioned itself as one of the most credible emerging green hydrogen export hubs, leveraging its exceptional solar and wind resources in the southern Sahara and its geographic proximity to European markets. The Moroccan government has attracted major European energy companies and signed framework agreements with Germany and the EU under the H2 Mediterranean initiative. The planned NOUR and Aman hydrogen projects envision large-scale electrolysis facilities feeding ammonia export terminals. However, significant financing gaps remain, and the country’s infrastructure investment requirements — desalination capacity for water feedstock, upgraded port terminals, dedicated pipeline corridors — are substantial. Morocco’s trajectory illustrates both the genuine potential of green hydrogen to reshape energy geopolitics and the multi-decade, capital-intensive nature of realizing it.
