Day 5 Australia-Netherlands Hydrogen Research Delegation: Wageningen and Eindhoven Our last day! What a whirlwind it’s been, so many different people and places. Thanks for joining the journey with me through these posts. I hope that those who we’ve connected with can stay in touch beyond this delegation, and that people from both countries have found some value in this knowledge sharing. If there is one overarching theme we have found in this delegation it is that hydrogen is a team sport. We succeed together, or not at all. We need collaborations, consortiums, partners, common use infrastructure, shared visions and a collective will to tackle this global challenge head on. Day 5 was packed with travel, starting with a visit to Wageningen University and Research with the team specialising in separation and purification, particularly closed water and mineral loops. Gerhard De Ruiter started us off with an overview of the institute while Irma Steemers-Rijkse and Norbert Kuipers walked us through the groups circular approach to hydrogen production. Jolanda van Medevoort showed us their pilot plant which integrates waste heat, potentially from electrolysis, with a membrane distillation approach to water purification. The idea is to use temperature difference driven membrane distillation to purify sea water to be fed directly to electrolysis, using 1/10th of the energy required for traditional RO approaches. There were also multiple additional options that could be considered such as brine crystallisation for mineral recovery, as well as a small kick back of energy recovery to increase overall efficiency. It was even possible in some scenarios to use waste heat from electrolysis to generate 2-3 times as much pure water as required for the electrolyser. Potentially, this could be a win-win for water scare communities to produce both hydrogen and water efficiently. In the afternoon we visited TU Eindhoven and the team of Professor Philip De Goey, working on iron as an energy carrier. Vet Piet-Jan (Metalot) and Guy Willems (IRON+) and PhD student Nicole Stevens assisted in a tour from Jesse Hameete of the Zero Emission Lab. The novel approach uses successive iron oxidation and reduction to potentially export energy long distances the end goal being mostly for efficient industrial heat generation. The technology is being scaled and commercially explored with Metalot and as well as seeing the labs at TU Eindhoven we trekked out to the pilot facility of Metalot to see the iron combustion process in action. An interesting proposition to use iron as an energy carrier, I’ll be watching the technology progress with great interest! The team certainly provided the best snacks of the tour… Over and out! See you on the other side (of the world).
