Apollo has conducted a comprehensive DEFINE study on the Hydrogen Offshore Production Project (HOP2) for the Net Zero Technology Centre (NZTC) in the United Kingdom. The project, supported by a £2.12M grant from the Scottish Government’s Just Transition Fund, aims to pioneer large-scale offshore green hydrogen production by repurposing existing oil and gas infrastructure on the UK Continental Shelf (UKCS) and exploring new offshore facility construction. Led by expert engineers, the study meticulously analyzed the HOP2 project, focusing on utilizing offshore structures while prioritizing safety, efficiency, and operational excellence. The evaluation encompassed offshore asset assessment, equipment list development, and layout option assessment, with a specific emphasis on the hydrogen production process involving water treatment, electrolysis, and compression. The study's recommendation included viable options for creating new offshore assets or repurposing existing ones, advocating for collaboration with suppliers to develop tailored electrolyser designs suitable for offshore application. The findings reinforce Apollo's dedication to advancing green hydrogen production in alignment with environmental objectives. Phil Westmorland, Apollo’s Decarbonisation Director, expressed the study's significance in progressing renewable energy technologies and attaining positive economic and environmental outcomes, marking a milestone towards decarbonisation.
