The Stronghouse Hydrogen Tour
The main reason for this tour was to gain more practical insights into the hydrogen chain, which is of great importance when connecting neighbourhoods and individual houses to green hydrogen. Topics such as the required hydrogen network, hydrogen equipment, training and public support were all tackled during the course of the event.
Starting early, the first stop on day 1 found the participants at the Hydrogen Tiny House in Hoogeveen. Here, various partners and associates from the Waterstofwijk Hoogeveen presented different aspects of this innovative project and the roles played by a number of organizations. Within the Stronghouse project, Hoogeveen shares their hydrogen knowledge and expertise with the other partners and will illustrate the important contribution green hydrogen can make to the natural gas-free, Dutch housing stock by:
• reusing the existing natural gas network
• installing a new hydrogen central heating boiler
Kees Boer, Project Manager and tour organizer from the Municipality of Hoogeveen, introduced an impressive line-up:"It's very energizing to be able to facilitate this kind of exchange between local, national and international stakeholders." Besides speakers from the Municipality, participants were treated to presentations from representatives of the residents of the Waterstofwijk Hoogeveen, RENDO (gas network), Alfacollege (Technical College developing new educational courses on H2), REMEHA (installation company) and entrepreneurs excited to share the potential of hydrogen as a sustainable energy source.

EnTrance Centre of Expertise
The journey then continued towards Groningen for a session at the EnTranCe Centre of Expertise. Lecturers from the Hanze University of Applied Sciences shared their insights on a series of projects and research, while Stronghouse partners from the Robert Gordon University (Scotland) and Vives Hogeschool provided a transnational perspective. Next on the programme - a guided tour of the hydrogen test centre (WING) and BuildinG! where sustainable innovations are developed, applied and shared.

Gasunie & HEAVVEN
Finally, between courses at dinner in Groningen, the group was also treated to more inspiring presentations from the Gasunie and HEAVENN The Gasunie aims to develop the hydrogen market and stimulate supply and demand so hydrogen becomes just as affordable as green gas and electricity. HEAVENN is a large-scale, six-year programme of demo projects in the Northern Netherlands which is bringing together the production, distribution, storage and local end-use of hydrogen into a fully-integrated and functioning “H2 valley” (H2V), that can serve as a blueprint for replication across Europe and beyond. The hydrogen neighbourhood in Hoogeveen is also part of the HEAVENN programme.
GAE - Hydrogen Valley Airport
"On the second day of the tour, we were intrigued to learn more from our German partners in Bremerhaven about the hydrogen initiatives in that region," Kees continues."But first we had a planned stop at Groningen Airport Eelde to learn more about their future plans." Jonas van Dorp - the regional airport's Commerce, Communication and Business Development Manager - presented the H2 Ground Power Unit (GPU), shared the latest updates as the first Hydrogen Valley Airport and provided a tour of the facilities. Kees: "We were really grateful for this behind-the-scenes view. It was great to see such innovative sustainable initiatives up close and learn more about GAE's role as an aviation test bed."

H2 in Bremerhaven
In Bremerhaven, Stronghouse colleague Till Scherzinger had arranged a series of visits. First stop was the 'MICROGRID' sub-project at Bremerhaven University of Applied Sciences. A cycle has been created in which green hydrogen is produced and stored with the help of renewable energy sources. If necessary, this can also be used as an energy source for the supply of electricity and heat to a wide variety of building structures.
Microgrid, production, storage
Till explains: "With the help of the model setup in the MICROGRID container on the university campus, it's possible to make statements about storage density, safety, service life, user-friendliness, freedom from maintenance and the energy self-sufficiency of so-called island grids in the future. This could be used to promote 'green electricity' supply to households. We see the connection with what our Stronghouse partners in Hoogeveen are doing. We can always learn more from each other."
Wind & hydrogen
At Fraunhofer IWES the participants heard more about the Hydrogen Lab Bremerhaven and the interaction between wind turbines and electrolytic hydrogen production. The test site is still under construction but, once complete, this will offer a highly innovative infrastructure where scientists can test the interaction between a wind turbine and electrolyzer on a real scale, among other things. The deep, cross-sector integration of electrolysis (e.g., through the use of by-products) as well as the use of reconversion technologies for microgrid and grid-supporting applications, is also part of the scientific work being carried out here.
With the Hydrogen Lab Bremerhaven, Fraunhofer IWES is advancing the integration of hydrogen technologies into the energy-economic system at both a national and an international level, as well as accelerating green hydrogen production.
Testing H2 applications
The last tour stop was the ttz Bremerhaven, part of the project Grüner Gas für Bremerhaven. This facility is for testing hydrogen components and integrated systems in 3-dimensional space - a unique trial infrastructure, available to test new technologies with hydrogen applications. Here again, the group were treated to many fascinating examples of what is potentially possible using H2 as an energy source in the near future.
All in all, this was a truly inspiring event for all delegates - although a few did sometimes struggle with the amount of technical details. Certainly, it was a remarkable, knowledge-packed event - a Stronghouse exchange highlight!
