-The HYPOP consortium has published Guidelines for public engagement on hydrogen technologies’ implementation, now available for download from the HYPOP project website (hypop-project.eu).
-The guidelines are based on extensive evidence from public engagement activities, including co-creation workshops, webinars, public opinion surveys, social media analysis, and a social life-cycle assessment.
-The document translates this evidence into practical public engagement tools and recommendations for people involved in the delivery, policy and communication of hydrogen-related projects.
It provides a step-by-step toolkit with templates and checklists to plan, implement and evaluate engagement activities, ensuring processes are safe, inclusive, accessible, and perceived as legitimate by communities.
Transparent, sustained engagement is highlighted as key to building public trust in hydrogen technology over the long term.
Europe needs the public on board if hydrogen is to live up to its promise of cleaner air, energy security, and industrial growth in support of the green transition. That is why the EU-funded HYPOP (HYdrogen Public Opinion and accePtance) project spent the past two years gathering insights from citizens across Europe. Those insights have now been distilled into a comprehensive set of guidelines for public engagement on hydrogen technologies, published earlier this month on the HYPOP website. These guidelines provide a practical toolkit for anyone designing and delivering hydrogen-related projects, ensuring meaningful public engagement and trust from local communities.
Readers will find advice on how to plan outreach, how to tailor materials for different audiences, how to run safe, accessible and inclusive engagement sessions, and how to monitor and evaluate their impact. The 40-page document comes with ready-to-use templates, checklists and example materials, so that policymakers, municipal officers, project developers, non-profits and industry teams can readily adopt best practices. From preparing transparent information on hydrogen safety to setting up feedback surveys, each part of the toolkit is practical and backed by evidence of what works in practice. Everything is geared towards helping hydrogen initiatives engage communities early, openly and continuously making new technologies easier to trust and local projects smoother to implement.
Why it matters
As the EU aims to produce 10 million tonnes of renewable hydrogen by 2030, public acceptance will determine whether these projects thrive or face opposition. Poor or late engagement can lead to mistrust, delays and costly setbacks, while good engagement builds understanding and support. HYPOP’s findings point to three essentials for keeping communities on side:
–Be transparent. Set out benefits, costs, risks and uncertainties plainly, and address difficult questions without hedging.
–Use evidence with stories. Pair sound data with clear, relatable examples and visuals that connect to everyday life.
–Make it two-way. Involve people early and throughout, creating real opportunities for input and shared problem-solving.
Now published, the HYPOP guidelines put these principles into practice, helping ensure Europe’s hydrogen roll-out is people centred from day one. By involving communities at each stage, from planning and design through to operation and decommissioning, project teams can surface concerns early, adapt to local needs, and build the sustained trust required for large-scale deployment.
“By distilling extensive public insight into a single, practical resource, these guidelines make it easier for every hydrogen project to engage its community early and effectively,” said Daniela Martin, Director of Communications at the Institute for Methods Innovation (IMI), who leads HYPOP’s public engagement efforts.
“Meaningful, transparent engagement over the long term is not a tick-box exercise; it is how public trust is built so hydrogen technologies can succeed.”

About the Institute for Methods Innovation (IMI)
Founded in 2017, the Institute for Methods Innovation (methodsinnovation.org) is a scientific, charitable, and non-profit institute working internationally to advance the use of evidence in real-world decision-making. We specialise in practical research and evaluation methods that support learning, strategy, and impact across various fields, including policy, education, science communication, and public engagement. Through expert-led training, collaborative research, and tailored support, we help our partners apply evidence to design more effective programs, engage communities, and assess what works. Our team brings deep expertise in social science, participatory methods, and evaluation, helping others build their capacity to use evidence with confidence.
