HiWhyV

High Coast to West Coast Hydrogen Valley

01/01/2026

31/12/2031

HiWhyV will establish Sweden’s first large-scale hydrogen valley, bridging two complementary regional hubs to create a national strategic corridor:

West Coast Hydrogen Hub: Home to the nation’s highest hydrogen demand and its primary industrial infrastructure.
High Coast Hydrogen Hub: One of Europe’s most competitive regions for renewable hydrogen production.

Together, these hubs form a dual-valley model that integrates production, conversion, storage, transport, and end-use across multiple sectors, including industry, transport, and energy. HiWhyV will deploy 994 MW of electrolysis capacity across nine hydrogen nodes, producing up to 132,000 tonnes of renewable hydrogen per year.

The project features a cutting-edge industrial symbiosis approach, repurposing waste oxygen and residual heat for aquaculture and district heating networks, significantly enhancing overall system efficiency and circularity.

Strategic Objectives

Large-Scale Deployment: Install 994 MW of electrolysis capacity and produce 132,000 tonnes of green H₂ annually across 9 usage nodes (including e-SAF, e-methanol, and green fertilizers).
Environmental Impact: Drastically reduce the carbon footprint of the involved Swedish regions through sector coupling.
Safety Excellence: Implement a project-level hydrogen safety management plan with standardized strategies and risk management protocols.
Social Integration: Establish the “HiWhyV Transition Arena”, an inclusive co-creation framework to foster regional hydrogen adoption and social acceptance.
Economic Growth: Strengthen regional innovation ecosystems and create high-skilled jobs by scaling hydrogen value chains.
European Replication: Foster the rollout of Hydrogen Valleys across Europe by transferring the HiWhyV model and tools to 3 replication regions, accelerating the EU’s clean energy transition.

El papel de la fundación

The role of the foundation

In the HiWhyV European project, the Aragon Hydrogen Foundation (FHa) plays a pivotal role in supporting the replication and upscaling of Hydrogen Valleys across Europe. Leveraging its extensive experience in large-scale hydrogen initiatives, FHa translates technical project knowledge into practical, transferable solutions for emerging regions.

Leadership in Replication & Analytical Tools

FHa leads the work package focused on replication activities, bridging methodological development with real-world territorial application. A core contribution is:

HTP Tool 2.0: FHa leads the development and deployment of this web-based analytical tool. Utilizing multi-criteria optimization, it evaluates complex hydrogen value chains across production, storage, transport, and demand.
Decision Support: The tool is applied in replication studies across various European regions, supporting scenario analysis, validation, and informed decision-making in close cooperation with local stakeholders.

Strategic Impact and European Legacy

FHa contributes to the project’s high-level strategic outcomes, ensuring HiWhyV’s influence on the European hydrogen economy:

Standardization: FHa co-develops the HiWhyV White Paper and a European Standard Procedure for the design and deployment of new Hydrogen Valleys, structuring best practices and strategic roadmaps.
Clustering and EU Synergy: FHa leads cross-cutting activities in coordination, communication, and clustering, fostering collaboration with other EU projects and stakeholders to reinforce the long-term legacy of HiWhyV.
