STRING

What STRING does

STRING Megaregion is a political membership organization founded in 1999 and headquartered legally in Sorø, Denmark (via Region Zealand as legal body, CVR 29190658), with its operational Secretariat based in Copenhagen. The organization coordinates cross-border cooperation among 16 member entities — 7 cities (Hamburg, Kiel, Copenhagen, Malmö, Helsingborg, Gothenburg, Oslo) and 9 regions across Germany, Denmark, Sweden, and Norway — representing approximately 14 million inhabitants. Its stated mission is to accelerate the green transition by aligning political, industrial, and geographical priorities across the Northern European megaregion, with three strategic pillars: deploying sustainable cross-border transport infrastructure, positioning the region as a globally recognized green hub (cited by OECD as a top-20 global hotspot for green tech patenting), and building a cohesive megaregion through institutional cooperation.

STRING's core products and initiatives center on policy advocacy and project coordination rather than commercial technology offerings. The portfolio includes: the GREATER4H Hydrogen Corridor, an EU CEF-funded cross-border hydrogen refueling infrastructure project from Hamburg to Oslo; H2ignite, an Interreg North Sea Programme project (2024-2027) developing hydrogen business models across Sweden, Denmark, Netherlands, and France; advocacy for major physical infrastructure including the Fehmarn Belt Fixed Link (immersed tunnel opening 2029) and double-track rail upgrades on the Scandinavian-Mediterranean corridor; knowledge products including OECD Strategic Papers, IfW Kiel development assessments, SWECO rail freight analyses, and a Political Innovation Guide; and The Green Industrial Revolution Radio podcast. Underlying technical work focuses on green hydrogen mobility infrastructure, fixed-link construction coordination, and rail interoperability — physical infrastructure rather than digital platforms.

STRING's business model is non-commercial, funded through recurring membership contributions from 16 local and regional government authorities plus competitive EU co-funding (Interreg North Sea Programme, Connecting Europe Facility). The organization generates no product or service revenue and has no disclosed pricing. Go-to-market is structured around quarterly Political Forum governance, an annual State of the Megaregion Day conference in Brussels, international participation (COP29, OECD forums, European Week of Regions), and a portable exhibition deployed at political festivals. The Secretariat of ~11 staff led by Managing Director Thomas Becker implements political decisions and drives day-to-day coordination across a consortium that includes major corporate partners (Volvo Technology, DFDS, Hafen Hamburg Marketing), academic institutions (University of Copenhagen, IfW Kiel, Europa-Universität Flensburg), and pan-regional bodies.

Direct peers

• Greater Copenhagen: Cross-border political cooperation organization covering the Copenhagen-Skåne-Halland region. Directly comparable to STRING as a politically-driven membership body coordinating infrastructure, investment promotion, and green transition across national borders in Northern Europe.
• Mälardalsrådet: Regional political council for the Mälardalen region in Sweden. Recently partnered with STRING on the Political Innovation Guide and operates a comparable political membership model for Swedish regional authorities.
• Kvarken Council: Finnish-Swedish cross-border cooperation body along the Gulf of Bothnia. Co-authored STRING's Political Innovation Guide and operates an analogous political membership model focused on cross-border connectivity in Northern Europe.
• Öresundskomiteen (Öresund Committee): Danish-Swedish cross-border political committee promoting integration between Copenhagen and Skåne. Closely comparable governance model — political members, consensus decision-making, and infrastructure advocacy — and an existing STRING member counterpart.

Broad incumbents

• Benelux Union: Cross-border political and economic union of Belgium, Netherlands, and Luxembourg. Comparable as a multi-country political cooperation model addressing cross-border infrastructure, mobility, and economic integration in Europe.
• Nordic Council: Inter-parliamentary body for Nordic governments (Denmark, Finland, Iceland, Norway, Sweden, Faroe Islands, Greenland, Åland). Operates at a wider Nordic scale than STRING but shares the political cooperation mandate across the same national jurisdictions.
• Euregio Rhine-Waal: Dutch-German cross-border cooperation organization along the Rhine-Waal border. Analogous European cross-border governance model addressing infrastructure, labor mobility, and economic development — a representative peer among many European EGTC-equivalent entities.
• European Union Strategy for the Baltic Sea Region (EUSBSR): EU macro-regional strategy coordinating policy across 8 Baltic Sea countries. Comparable as the supranational coordination layer STRING operates within — particularly relevant for CEF/Interreg funding alignment and Scandinavian-Mediterranean corridor planning.

Emerging players

• Cascadia Innovation Corridor: Cross-border megaregion initiative connecting Oregon, Washington, and British Columbia around innovation and clean economy themes. Conceptually analogous to STRING as a cross-border political-economic megaregion framework, though in a North American context.

Regional players

• ScanMed Corridor (TEN-T): The EU's Scandinavian-Mediterranean Trans-European Transport Network corridor, which physically runs through STRING's geography. STRING's rail advocacy (Oslo-Gothenburg, Fehmarn corridor) directly feeds into ScanMed planning — making it both an infrastructure peer and a coordination counterpart.
