Clear Hydrogen UK Ltd has announced an expansion of its agreement with Proton Technologies. In 2021, Clear Hydrogen UK’s founders invested CAD 3.7 million in Proton to obtain a 20 tonne per day production license for use in the UK and Ireland. The expansion announced is 250x larger, giving an implied total license value as high as USD 925 million CAD for 5000 tonnes per day. Terms include 45% ownership of CHUK going to Proton, who will be providing increased technical support and governance oversight to CHUK’s team. Two of Clear Hydrogen UK’s founders will also be joining the board of Proton.Proton has the lowest-cost method for producing Clear Hydrogen, which is the most environmentally friendly and lowest cost method to make hydrogen. The plan is to produce Clear Hydrogen from the UK’s aging offshore oil assets while sequestering vast amounts of CO2 as solid carbonate within the same systems.
