Hyundai Motor and Kia collaborate with Next Hydrogen to develop advanced alkaline water electrolysis system.
- Hyundai Motor, Kia and Next Hydrogen sign MOU to develop an advanced alkaline water electrolysis system that helps produce green hydrogen economically
- The companies aim to develop a more efficient stack for the system, and explore potential technological applications and commercial arrangements in the future
Hyundai Motor Company and Kia Corporation have signed a memorandum of understanding with Next Hydrogen Corporation, a Canadian company specialising in water electrolysis technology and a subsidiary of Next Hydrogen Solutions Inc., bolstering their efforts to usher in a global hydrogen society through cost-effective production of clean hydrogen.
Under the agreement, the companies will jointly develop an alkaline water electrolysis system1 and its related stack for the purpose of generating green hydrogen economically and exploring new business opportunities and technological applications.
Today it is expensive and time consuming to produce clean hydrogen. Due to this reason, Hyundai Motor, Kia, and Next Hydrogen are looking to improve the price competitiveness of clean hydrogen in consideration of regional climate and environmental characteristics. The companies, which are expanding their base by examining the strengths and weaknesses of various water electrolysis technologies, agreed to explore the possibility of alkaline water electrolysis system among various water electrolysis technologies this time.
Among the various methods of water electrolysis, the alkaline water electrolysis system is regarded as technologically one of the most rigorously tested and proven means with a long track record of research and development. Also, it has the advantage of being able to produce large-scale hydrogen and using relatively inexpensive catalysts, making facility costs low.
The aim is to advance stack-related technologies that are at the core of the alkaline water electrolysis system to reduce the cost of building the system and maintaining/operating the system. The key benefit to be derived from the project is that by enhancing the performance of stack-related technologies in the alkaline water electrolysis process, it will be possible to develop a new stack which can be operated at high current density2 and produce green hydrogen economically.
1 Alkaline water electrolysis system: A hydrogen production method that electrolyzes water using an alkaline electrolyte such as potassium hydroxide (KOH) or sodium hydroxide (NaOH).
2 High current density:The more electricity available, the more hydrogen the alkaline water electrolysis system produces. Thus, an alkaline water electrolysis system equipped with a stack capable of carrying high current density can achieve higher economic efficiency by producing more hydrogen while taking up the same area.
