The containerised MC500 unit will be delivered to the Association for Waste Disposal in Buchs. The electrolyser will produce green hydrogen using renewable power from a 190,000-tonne-per-year waste incineration plant.

Rather than letting residual electricity go unused or into the grid, the project diverts that power to produce green hydrogen, closing a circular loop by fuelling regional demands, such as the local waste collection fleet.

H2 Energy’s electrolyser order represents the second MC500 system it has ordered from the Norwegian OEM, alongside a containerised MC400 and a smaller C30 PEM unit.

“H2 Energy has a long history of trusted cooperation with Nel dating back to 2016… we have installed and operated an MC400 PEM electrolyser for over 30,000 hours… and racked up over 12,000 hours on an MC500 with our customer WPO,” explained Rolf Huber, H2 Energy founder and Chairman.

“These two H2 plants form the backbone of the Swiss green hydrogen ecosystem, fuelling a network of 18 refuelling stations and propelling a fleet of heavy-duty fuel cell trucks over 14,000,000km.”

The MC500 is part of Nel’s next-generation PEM portfolio, and can reportedly produce up to 1,100kg of hydrogen per day under optimal conditions, making it well-suited for light industrial fleet refuelling or supporting regional hydrogen hubs.

With Nel’s 2025 Q2 revenues down 48% and project execution delays weighing on its alkaline segment, the company has emphasised the relative stability of its PEM business, which saw flat revenues and 11% year-on-year backlog growth.
