Scientists at the University of Aberdeen are spearheading technology that could redefine the region’s energy landscape, turning depleted oil and gas reservoirs into green hydrogen banks. This innovation not only aligns with Scotland’s ambitious net-zero goals but could also position the nation as a net exporter of hydrogen.
At its core, this research aims to convert excess electricity generated by renewables into green hydrogen, effectively storing it in depleted oil and gas reservoirs. This visionary approach not only mitigates the need for constraint payments to wind farm operators but also provides a second life for aging reservoirs, aquifers, and their associated infrastructure.
The first phase of this groundbreaking project involves the development of digital tools for transporting hydrogen through the North Sea pipeline network, both onshore and offshore. This digital infrastructure will play a pivotal role in supplying homes and businesses with green hydrogen.
Venturing into uncharted territory, the second phase of the project explores the co-storage of hydrogen and carbon dioxide (CO2) in depleted hydrocarbon reservoirs and aquifers. By utilizing CO2 as a “cushion” gas, this technique could scale up the storage of blue hydrogen and its associated CO2 emissions.
Scotland’s dedication to becoming a net exporter of green energy is underscored by the Hydrogen Backbone Link project, funded by the Scottish Government. This initiative sees hydrogen as a linchpin in Scotland’s renewable energy export ambitions.
Support from Key Stakeholders
Crucially, this research has received backing from the Net Zero Technology Centre’s (NZTC) Net Zero R&D Programme, a collaborative effort funded by the Scottish Government, Scottish Funding Council, and Scottish Enterprise. Industry partners, including North Sea operators and energy consultants, are also contributing to the project’s success.
According to Dr. Prashant Jadhawar from the University of Aberdeen, this research is a potential “game-changer” for Scotland’s energy future. With estimates of up to 20TWh of hydrogen storage capacity and the permanent sequestration of 50 million tons of CO2, the project could play a pivotal role in meeting Scotland’s ambitious target of 5GW of green and low-carbon hydrogen production by 2030.
As Dr. Jadhawar presents this groundbreaking research at the Offshore Europe conference, the world watches with anticipation. Scotland’s journey from oil and gas reservoirs to green hydrogen banks could be a blueprint for a sustainable energy future, bridging the legacy of the North Sea with the promise of a greener tomorrow.
