Technology group Wärtsilä has teamed up with a consortium led by the University of Vaasa to develop the Integrated Hydrogen-Argon Power Cycle (iHAPC) with the aim of enhancing engine efficiency and driving Net Zero power generation. This innovative approach involves replacing traditional air with a mixture of argon and oxygen in internal combustion engines, along with hydrogen fuel. The use of argon's inert properties allows for higher efficiency, with water being the only by-product in a closed-loop system where argon is continuously recycled. The project aligns with Wärtsilä's commitment to accelerating the transition to renewable energy and improving the efficiency of engines crucial for stabilizing grids reliant on wind and solar energy. The iHAPC initiative is part of the broader WISE programme and involves collaboration with various partners to advance sustainable energy solutions. Professor Maciej Mikulski of the University of Vaasa emphasized the transformative potential of the hydrogen-argon power cycle in achieving unparalleled power generation efficiency. The project aims to capitalize on the increasing global production of sustainable hydrogen to enable the widespread adoption of green technologies.
