Subsea Hydrogen Storage and Infrastructure – for stable energy as electricity or hydrogen to consumers in the ocean space
Taking advantage of years of knowhow and experience from subsea and combining with new knowledge, enables new possibilities in the energy transition journey
6 years ago we asked the question: How could we utilize the competency within subsea to enable CO2 reduction? Later the idea of Deep Purple was incepted.
Deep Purple is about researching the problem of reducing CO2 and finding solutions. We started by looking at the Oil & Gas domain on the Norwegian Continental Shelf where we identified interesting concept for reducing significant C02 emissions.
NCS have excellent wind conditions however this energy source is highly intermittent and energy storage is inevitable. Since Hydrogen is noted as a candidate for seasonal GWh energy storage medium, we looked into how this could be realized. Compressed Hydrogen with GWh capacity was studied. By utilizing subsea knowledge to place the storage under water, we get access to lots of space to place large size storage tanks in a safe and stable environment.
For the subsea hydrogen infrastructure, the scope is to select concepts and qualify technology to TRL level 6 EU scale which means: tested in realistic simulated environment. Selected elements to be qualified are connection system, pipelines, risers, storage tanks, and storage system. The presentation will cover status on how far we have come and what the learnings are so far.
