Johnson Matthey and Hoeller Electrolyzer partner to focus on next generation electrolyser stacks with greater efficiency, driving down the cost of green hydrogen

Johnson Matthey (JM), a global leader in sustainable technologies, today announced the agreement of a Memorandum of Understanding with Hoeller Electrolyzer GmbH who have more than 25 years of expertise and pioneering work in PEM technology. Under the agreement, JM will collaborate with Hoeller Electrolyzer to provide catalyst coated membranes (CCMs) for their innovative PROMETHEUS range of proton exchange membrane (PEM) stacks developed for electrolyser systems. Both companies are committed to supporting the transition to net zero by providing high quality stacks for a range of applications, while continuing to develop the next generation of innovative stacks and CCM components for the future.

The collaboration will focus on joint research and development in conjunction with a fast-track manufacturing scale-up programme that will accelerate the launch of the PROMETHEUS stacks range within the next 12 months. In addition, the partnership will continue to develop next generation electrolyser stacks with greater efficiency levels, ultimately helping lower the costs associated with green hydrogen production.

Neither Johnson Matthey nor Hoeller is new to electrolysis; instead, both will build on their vast experience and proven track record developing innovative, high-performance components for fuel cell applications. Johnson Matthey is also driving the transition to net zero by creating closed loop recycling systems within the electrolysis supply chain that will recycle and re-use as much of the key raw materials contained in the CCM as possible.

“Everything we do contributes to our vision of a cleaner, healthier world, so I am incredibly pleased that we are working with Hoeller Electrolyzer to accelerate the commercialisation of their high quality, innovative PROMETHEUS stacks”, commented Ralph Calmes, Managing Director, Hydrogen Technologies. “Building on our collective experience in membranes, we are confident that we will deliver on the aims of the MoU, reducing the cost of green hydrogen and, in doing so, accelerating the transition to a net zero world.”
