This report, developed within the Interreg Baltic Sea Region H2Deri@BSP project, presents a comprehensive market analysis of hydrogen derivatives across eight countries bordering the Baltic Sea. It examines current and future demand, production capacities, infrastructure readiness, regulatory conditions, and import and export possibilities, providing a solid foundation for strategic decision-making by port authorities, energy companies, and policymakers. The analysis is based on an extensive literature review and desktop research covering more than 490 scientific and industry reports, 26 EU level policies and regulations, national policy documents, as well as market outlooks. It also builds on stakeholder engagement through two structured surveys with responses from 28 ports and 13 energy companies, 14 semi-structured interviews, and two multi-stakeholder workshops. A mapping and synthesis exercise identified nearly 300 hydrogen-related projects across the Baltic Sea Region, of which roughly 240 are still in the planning or feasibility stage, according to open sources. Together, these efforts provide both a quantitative overview of current developments and a qualitative assessment of stakeholder perspectives on opportunities and barriers in the emerging hydrogen derivatives market.
