Clyde Hydrogen Systems, based in Glasgow, has partnered with Hebrides-based PlusZero to showcase its decoupled electrolyser technology outside the lab. The collaboration aims to provide high-pressure green hydrogen reliably, safely, and cost-effectively. PlusZero, supported by the Scottish Government, plans to set up a green hydrogen production facility at the Creed Hydrogen Skills and Innovation Centre in Stornoway. The project integrates green hydrogen production, training, research, and field testing of electrolyser technology. On the aviation front, the Sustainable Aviation Test Environment (SATE) in the Highlands and Islands is part of the Civil Aviation Authority's Hydrogen Sandbox initiative to explore hydrogen fuel and propulsion in aircraft. The consortium, led by HITRANS, will focus on implementing hydrogen infrastructure changes at Kirkwall Airport for potential nationwide expansion. The ultimate goal is to enable commercial use of hydrogen-fuelled aircraft at remote and rural airports, contributing to a more sustainable aerospace system and supporting UK economic growth. The projects demonstrate Scotland's commitment to innovation, green energy, and sustainability in both hydrogen production and aviation propulsion.
