Green hydrogen is produced from renewable energy sources and one of the few technologies able to offer long-term energy storage, green fertilisers and green steel, so it鈥檚 a hot topic as Aotearoa strives to become a net-zero carbon economy by 2050.
UC鈥檚 Deputy Vice-Chancellor Research听Professor Ian Wright听says the MBIE funding is a huge endorsement. 鈥淲e鈥檙e very proud that University of mini传媒 researchers are taking a leading role in this important area. Internationally there is growing interest in green hydrogen as concern rises about climate change and these projects could bring exciting and much-needed breakthroughs.鈥
UC Civil Systems Engineering academics Drs听Rebecca Peer听补苍诲听Jannik Haas听are leading a project that aims to develop an integrated energy system model for New Zealand that could provide sustainable transport, heating, and electricity.
The project 鈥 in partnership with one of the leading energy modelling groups in Europe, the听听鈥 will receive $2 million in funding over three years from MBIE and 鈧300,000 (NZ$478,700) from the German Ministry of Education and Research.
Dr Haas says their work will provide scientific evidence to inform a comprehensive green hydrogen strategy for New Zealand.
鈥淭he industry and transport sectors currently emit a high proportion of New Zealand鈥檚 greenhouse gases. We want to understand the role of green hydrogen in meeting New Zealand鈥檚 net-zero goal. How much we can use it cost-effectively and what for 鈥 including its potential as a fuel for planes and ships or potentially export it to the Pacific Islands - is what our project is designed to assess and quantify.鈥
UC Chemical and Process Engineering听Professor Aaron Marshall听is leading another Kiwi-German collaborative project that has been awarded $2 million funding over three years. The project鈥檚 goal is to develop a new type of electrolyser 鈥 a tool that splits water into hydrogen and oxygen 鈥 to produce hydrogen energy in a more cost-effective way.
Currently the most effective electrolysers are also the most expensive to make, but Professor Marshall says the team has the expertise to dramatically boost the efficiency of low-cost anion exchange membrane electrolysers, making them more financially viable.
鈥淭he people involved in the project have complementary skills and expertise. We鈥檒l be doing nano-scale imaging of electrochemical reactions to identify where gas is produced and understand what makes the reaction better. The findings from this could lead to further research into energy production and utilisation.鈥
