UK green hydrogen company Protium has officially inaugurated its second electrolytic hydrogen production facility, Pioneer 2, in Port Talbot, Wales.
With an installed capacity of 2.5MW and fitted with Nel PEM electrolyser systems, the plant can yield up to 1 tonne of green hydrogen per day at full output, 25 times the capacity of the company’s 0.1MW Pioneer 1 project.
Construction of the facility kicked off in November 2025. It delivered first hydrogen production in May 2026 and was officially commissioned on 30 June. Adopting a containerised modular design, the plant produces hydrogen with a purity of over 99.99%, which will be supplied via tube trailers to end customers in the transport, industrial and off-grid power sectors.
