A new study undertaken at the Aberdeen-based National Subsea Centre (NSC) aims to advance the potential of subsea green hydrogen storage for use in industries such as offshore oil, automotive and aerospace, and household heating.

As demand continues to increase for low and zero carbon energy solutions, green hydrogen technology has shown to be a viable alternative to fossil-based fuel. 

To help fulfil this need for clean energy, a joint research project between Robert Gordon University (RGU) and the Net Zero Technology Centre (NZTC) is exploring the design and optimisation of underwater tanks able to store pure hydrogen at a large scale. 

Stating that hydrogen is ‘at the heart’ of integrated energy, Jemma Reynolds, Integrated Energy Research Assistant, NSC, spoke about hydrogen, adding, “When pressurised or liquefied, it has the highest energy content per unit of weight.” 

“It’s a clean energy source that doesn’t produce any greenhouse gasses when utilised and is essential to meeting the Paris Agreement.” 

Research associated with the multi-million-pound NSC aims to lead integrated marine energy grids from design to construction to support the energy transition by using smart technologies. 

“Using the high-pressure depths of subsea conditions, this project will help to store hydrogen at scale in a clean, efficient, and safe way,” commented Professor James Njuguna, Integrated Energy Lead, NSC. 

“It will also help to reduce carbon emissions by decreasing our reliance on fossil fuels to produce hydrogen and support manufacturing opportunities as we increase efforts to meet demand.”
