PML scientists contribute to Royal Society’s Geological Carbon Storage briefing paper

The briefing explores the options for geological carbon dioxide (CO₂) storage, with the aim of permanently removing CO₂ from the atmosphere, and an emphasis on injecting CO₂ offshore into either deep saline aquifers or depleted oil and gas fields.

Head of Science: Marine Systems Modelling, Jerry Blackford said:

“We are proud to have been invited to collaborate on this briefing, needed now more than ever as the temperature on earth continues to rise.”

Global greenhouse gas emissions have increased by 12% in the last decade – amounting to the highest increase in decadal average emissions on record. If we are to limit warming to 1.5°C or less, future projections suggest that global greenhouse gas emissions must peak between 2020 – 2025, fall by 45% by 2030 and reach net zero by 2050.

To achieve these reductions and transition to a net zero energy system, there will need to be a significant decrease in carbon emissions. There will also be some end users, mainly those from industrial processes, agriculture, and heavy-duty transport, that will struggle to decarbonise by 2050 targets.

Jerry continues: “The deployment of carbon capture and storage will be vital to both capture emissions from residual point sources and for CO₂ removal from the atmosphere. CCS is required to achieve net-zero, and a key ally in our fight against climate change”.

What is CCS?

Carbon capture and storage is regarded as one of the more effective tools in the fight against climate change. The process involves separating the CO₂ generated during the industrial process, such as power plants, hydrogen and ammonia production and steel plants, then transporting the gas through pipes, in tankers via roads or ships and finally injecting the CO₂ directly into rock formations or depleted oil and gas reservoirs deep underground.

Is CCS safe?

Plymouth Marine Laboratory has a long research history that demonstrates that there is a very low risk of environmental impact from CCS operations. We are also developing methodologies that allow for both cost effective and sensitive environmental monitoring, providing a high degree of assurance that CCS is safe.

PML are world leaders in offshore CCS environmental research, having led the first ever real world CO₂ release experient in marine waters in 2012 and having leading roles in many CCS R&D projects over the last few years. Recently we were involved in an experiment in the North Sea, 130km northeast of Aberdeen, where a release of CO₂ was simulated over a period of 12 days at a depth of 120 metres and three metres below the seabed, which demonstrated that new technologies were able to detect even small releases of CO₂.
