CO₂ Energy Grid Battery Network

Gigaton CO₂ Ltd have developed a method of utilising CO₂ from CCUS and turning it into a giant battery capable of providing enough power to ultimately supply the entire Global Energy grid for at least 8 hours per day by 2050.

The Company recently filed a patent on a concept that takes large quantities of captured CO₂ and pressurises it until it is liquid (or supercritical). This CO₂ is stored in existing fossil fuel pipelines and caverns which could form an interconnected network covering anything from small geographical areas right up to countries and continents in the future where the CO₂ can be moved around to wherever it is needed.

The use of compressed gases to generate electricity is old technology as is manipulating the phase change of liquid to gas but what makes this unique and very exciting is the scale in which this can be deployed using largely existing infrastructure along with some clever manipulation of exactly what pressures to use to maximise results and the fact that CO₂ is a very nice molecule to use as it has a high potential energy store at fairly modest pressures.

The Benefits of this Technology Include:

Creation of a massive battery reservoir that can store very large amounts of energy
Power could be charged and discharged anywhere in the network.
The ability to move the CO₂ geographically could help form the backbone of a new ‘cableless’ energy grid.
Low CAPEX and time to market with a low carbon footprint and environmental impact as infrastructure already exists.
Creation of a network capable of holding Gigatons of CO₂.
Provide a useful application for captured CO₂ and would help kickstart carbon capture as there would be a ready market created for the captured CO₂.
Could provide a use for the massive global array of pipelines/caverns currently used for fossil fuels as we decarbonise.

It is a very neat solution that we believe could become a main linchpin as the world tries to transition from fossil fuels and capture its emissions.
