Zero Carbon Electric Grid

Subsurface Carbon Energy Storage

O_1.png

GeoSierra has adapted its multi-azimuth propped vertical sand plane technology to be an effective method for sub-surface closed cycling of supercritical carbon dioxide (sCO2) in legacy oil and gas reservoirs to develop large scale, highly efficient, robust Carbon Energy Storage (CES) schemes to achieve zero carbon electric grids.

 

Excess electricity generated from renewables is stored as potential energy, by pumping the sCO2 from the shallow reservoir down to the deep reservoir, in which the sCO2 has sufficient residence time to be heated to the deep reservoir temperature before being produced for electrical generation. A CES scheme installed in the legacy turbidite oil and gas reservoirs in Bakersfield, California would have an efficiency of 120%, i.e. it generates 20% more electric power than it stores from renewables.

 

The turbidite reservoirs in Bakersfield have produced 15 billion barrels of oil to date, with enhanced gravity drainage by CES, an additional 20 billion barrels of oil can be produced. A CES proof of concept trial is planned for Spring, 2023 in the Bakersfield turbidite reservoirs.

United Kingdom Energy Plan

The British Energy Security Strategy April, 2022 doesn’t mention energy storage, additional wind power is planned along with modular nuclear. A new review of shale fracking has been initiated by the UK BGS and NSTA, both of whom ignored GeoSierra's warnings of induced seismicity prior to the event at Preston New Road. The presence of slickenside bedding planes makes it physically impossible to fracture enhance the Bowland-Hodder shales by conventional hydraulic fracturing.

 

Currently the UK electric grid has 20GWe of gas fired turbines to match electrical supply to demand. The gas fired plants emit 45 million tonnes of CO2 per year directly to the atmosphere, and consume 140 million therms of natural gas per year.

 

If the UK installed 25GWe of subsurface CES in their offshore turbidite oil and gas reservoirs in the central North Sea, the 20GWe of gas fired electrical generation plants could be retired, and no new nuclear plants would be required. Capital and operating costs of offshore CES are much greater than onshore, but with the vast petroleum reserves in place and significant enhanced oil revenue, offshore CES could extend the life of these fields by over fifty years.
