Hydrogen cities
Twins Hydrogen Valleys with cities that want to decarbonise hard-to-abate local industry and heavy transport and improve air quality.
Description
Expected outcome
A growing number of cities across Europe is developing hydrogen strategies, either for mobility applications or for decarbonising their local and peri-urban industries and hard-to-abate sectors. By acting as experimentation and innovation hubs, these cities can be testbeds for the energy transition, balancing decarbonisation with competitiveness and social cohesion. Project results are expected to contribute to the following expected outcomes: Investments in - and deployment of - hydrogen applications and infrastructure for hard-to-abate sectors in and around cities to mitigate local air pollution and lead to economic growth and jobs, bringing urban environments at the forefront of sustainability and innovation. Communities of practice to foster the interaction between stakeholders from cities, ports, industry, local and regional government, as well as researchers and citizens. Enhanced synergies between the Climate-Neutral and Smart Cities Mission and the Horizon Europe Clean Hydrogen Partnership.
Scope
The selected project is expected to establish ‘twinning’ of Hydrogen Valleys (in particular those that have elements relevant for cities or ports) with cities that are interested to decarbonise their local and peri-urban hard-to-abate sectors using hydrogen and to improve air quality. Focus should be on hard-to-abate and/or hard-to-electrify sectors, such as industrial uses, heavy-duty and long-distance transport, aviation, maritime uses, or any combination thereof. The use of hydrogen for heating purposes is out of scope. Twinning will help cities to access the best available expertise and tools that can enable them to identify and implement decarbonisation strategies based on renewable hydrogen. To foster cooperation between cities and Member States, it is encouraged that there is a geographical balance between the participating authorities to foster learning from different projects and approaches. This twinning should be based on mentor-mentee pairings; these could also target enlargement countries, such as the Western Balkans, Ukraine, and Moldova. The project is expected to: Organise a selection procedure (for example in the form of public calls for expression of interest) to identify the most promising twinning pairs that will be selected to develop collaborative activities; Develop and implement for each twinning pair a tailor-made set of collaborative activities; Deliver for each twinned city a detailed roadmap outlining the future steps to integrate renewable hydrogen in their industrial decarbonisation; Facilitate the interaction between participating cities to address shared challenges and solutions; Collaborative activities can address for example: Feasibility assessments (including technology choices, sources of renewable hydrogen, business cases, regulatory issues and stakeholder engagement); Designing a detailed implementation plan (including funding strategy, permitting, infrastructure requirements, supply chain integration); Environmental and socio-economic impact assessment; Sharing best practices and lessons learned; Education and training. At least one of the cities selected for twinning is expected to be one of the 112 cities selected for the EU Mission on Climate-Neutral and Smart Cities . The project is expected to enhance the synergies between the Horizon Europe Clean Hydrogen Partnership and the EU Mission on Climate-Neutral and Smart Cities by making optimal use of the information available through the Hydrogen Valley Platform and the Cities Mission Platform . Under the guidance of the Cities Mission Platform, the selected project will engage in clustering activities with other relevant projects supported under the Cities Mission to promote synergies and complementarities. Proposals should ensure that appropriate provisions for activities and resources aimed at enforcing these synergies as well as clustering activities are included in the work-plan.
What this means for cities and regions
Cities and ports with heavy industry or long-distance transport that want access to Hydrogen Valley expertise for their own decarbonisation strategy. One coordination action is funded; heating with hydrogen is out of scope. Topic budget €5 million; 1 grant expected; around €5 million per project. Opens 9 February 2027; closes 7 October 2027. Copernicus atmosphere data can document the local air-quality gains that the topic asks cities to demonstrate.
