Hitachi Energy and University of Vaasa Partner on Transformer Efficiency for Hydrogen Production

Hitachi Energy and the University of Vaasa have signed a research collaboration agreement to enhance transformer efficiency and heat recovery in hydrogen production. The project, named Optimized Electric Power Chain for Electrolyser Systems (OEPCES), aims to utilize waste heat to improve energy efficiency, potentially reducing electricity consumption by up to 35% and increasing net efficiency to 85%. This initiative is part of the HEROES project, supporting Finland and EU climate strategies and advancing low-carbon industry.

Currently, around 70% of a hydrogen plant's operating costs are attributed to electricity, with significant losses due to heat. The project will develop a model for transformers to enhance their efficiency and integrate waste heat recovery systems. This effort is part of the HEROES project, aligning with Finland's and the EU's climate and hydrogen strategies.
