Renewable energy driven integration of hydrogen in the Danish O&G sector

Anders Koeler, CEO, Floating Power Plant
Offshore facilities like oil and gas platforms need electricity, but due to their location, they are often burning more than 10% of the fossil fuels retrieved from the ground in generators. This is a colossal waste of energy and a huge source of emissions. Combining energy vectors through the integration of a floating wind and wave energy system with a hydrogen "battery" provides a low, potentially zero, intermittency clean energy solution. This enables the effective integration of clean energy into several applications, including: • powering offshore assets, which require a reliable and consistent supply • powering remote islands with small grids, balancing production- and demand profiles without the need for fossil fuels to respond to demand peaks and low resource periods • offshore energy storage in larger grids, avoiding onshore environmental, visual, and social impacts, as well as removing the need to import reactive power The technology developed can also be readily configured to export hydrogen as a product, either to decarbonise the natural gas network or contribute to the growing hydrogen economy. The results of a study for Total Denmark will be presented, in which the partners, including FPP and TechnipFMC, developed the integrated concept for delivering power to an offshore platform and investigated the injection of hydrogen into the natural gas network. The progression of the design beyond this and plans for a demonstration and future commercial applications will also be presented, including a new business model for the system's commercial delivery. x
