Hydrogen trade and regulatory risk revolve around the challenges and uncertainties in the international exchange of hydrogen as a clean energy carrier. As hydrogen gains prominence for decarbonizing sectors like transport, industry, and power, cross-border trade of hydrogen and hydrogen-derived fuels (e.g., ammonia) is expanding. However, regulatory frameworks remain fragmented and evolving, creating risks for investors and traders. Key risks include inconsistent standards for hydrogen production methods (green, blue, grey), certification and guarantees of origin, safety and transport regulations, and tariffs or trade barriers. Divergent national policies can lead to market distortions, limiting hydrogen’s scalability and economic viability. Additionally, regulatory uncertainty complicates long-term contracts and infrastructure investments, potentially slowing market development. Addressing these risks requires international cooperation to harmonize standards, create clear certification systems, and align safety and trade regulations. Establishing transparent, stable policies will reduce investor risk, support supply chain development, and enable a robust global hydrogen market critical for achieving climate goals.
