At ScottishPower, he spentfive years leading hydrogen market development and business energy sales, spearheadingtwo multi-megawatt green hydrogen projects totaling more than £220 million.Both projects were government-subsidized and structured around 15-yeardecarbonization offtake deals in the glass and distillery sectors, displacingnatural gas with high-temperature heat and locking in long-term revenuestability. These projects established replicable commercial models forlong-term, high-value hydrogen supply in hard-to-abate industries and deepenedGriffin’s expertise in complex energy transition strategy, risk management, andlong-duration customer partnerships.
Prior to ScottishPower, Griffin spent more than adecade at BOC UK and Ireland, where he transformed a start-up industrial fuelcell business into a consistent growth engine, delivering 20% year-over-yearrevenue growth over six years.
