Ocean GeoLoop CCS
Ocean Geoloop has developed a new and unique process for capturing and storing CO2 emissions (CCS) from point sources. Such emissions are considered to be the dominant reason for the accelerating increase of atmospheric CO2, representing up to 70% of all annual anthropogenic emissions (26 gigatons).
The Ocean GeoLoop CCS is characterized by several unique capacities:
The separation of CO2 from flue-gas uses no harmful chemicals, no toxic materials and produces no pollutants.
As close to 100% removal of CO2 from the flue-gas as practically measurable.
Integrated in the future GeoLoop CCS will be an electricity generation module, the e-Loop, a novel and proprietary hydropower system. The e-Loop can produce electricity from low grade (< 100 C) waste heat sources (e.g. flue-gas) and is designed to deliver a capacity sufficient to supply all power required by the carbon capture and storage process. In addition, sale of surplus power will allow coverage of related capex/opex costs. The e-Loop puts the GeoLoop CCS in a unique and highly competitive position.
Other features of the GeoLoop solution help manifest the superiority of the technology. The approach represents a standardized and modular "one plant-fits-all" solution, meaning that there will be no need for special adaptations or other arrangements in most cases. All types of flue-gas CO2 contents, from less than one percent to more than 50%, can furthermore be handled in an economically viable manner.
Point Source Carbon Capture Pilot
Ocean GeoLoop introduces a new approach to permanent storage of captured CO2. Access to large volumes of safe storage space is a substantial challenge when highly compressed and pure CO2 is to be stored permanently underground.
Ocean GeoLoop favors a different route, avoiding the use of pure CO2. Instead, we use diluted CO2 dissolved in sea water, as ultrasmall, inert and buoyancy neutral gas nanocavities. This solution has much lower demands on the quality of the storage volume, since the nanocavities will not escape to the atmosphere via any known natural mechanism, even if stored in the open sea. This makes two storage options particularly attractive:
- Abandoned oil-gas reservoirs, which can be used without the strict security qualifications that follows the storage of highly compressed, pure CO2
- Deep ocean (sea floor), at depths of more than 2,000 m
In oil-gas reservoirs a CO2 percentage of 1 - 10% per cubic meter of water is deemed feasible, subject to local conditions. In the deep ocean this is reduced even further, to 0.7g CO2/m3 of water, equal to the CO2 per m3 of air mixed into the ocean through natural processes. This amount of CO2 represents just a fraction of the CO2 already present in every m3 of the ocean (average 140 - 160g/m3. In both cases the diluted nanocavity CO2 will rapidly be further converted into pH stabilizing, acid-base balance maintaining bicarbonate or be permanently mineralized as calcium carbonate rock (CaCO3).
Regarding deep sea storage, there are few, if any, documented occurrences of anthropogenic CO2 at ocean depths larger than one thousand meters. It is estimated that the oceans only upwell water from 1,000 m depths once every thousand years at the most (ref. IPPC 5th assessment report). At depths of 2,000 m or larger no substantiated information is available, but the lack of human CO2 indicates that CO2 deposited at such depths, at least will stay there for very long periods of time, possibly permanently.
The enabler step, the CO2 nanocavity conversion, is proprietary to Ocean GeoLoop.
e-Loop electricity enables 100% clean, large scale hydrogen production through water electrolysis. Hydrogen gas can be cooled into liquid state.
Ethanol can be made from CO2, water, and e-Loop electricity, supported by an electro-catalyst made from atomically dispersed copper on a carbon powder support.
Methanol can be made from the same CO2 & hydrogen.
Such ethanol and methanol used as e-fuel shall represent a uniquely clean and environmentally friendly alternative to other e-fuel options if so decided. The storage option is possible due to the low cost of the GeoLoop production of the two critical fuel components (CO2 and hydrogen).
Just as important as the removal of surplus CO2 from the atmosphere, is yet another capacity of the GeoLoop: Permanent supply of oxygen to the entire ocean column, enabled by the nanocavity technology.
Often overlooked is the fact that the health of the oceans and their life forms is closely related to the oxygen levels. Oxygen is the basis for all higher forms of life in the ocean. However, the oxygen content of the oceans is in decline, as a result of human induced run-offs of nutrients from land to sea, in particular nitrogen and phosphorus, from agriculture, industry, sewage leakages, etc. This has resulted in a growing number of oxygen depleted or dead zones in the oceans (no oxygen left). A driving force is the breakdown of organic material by bacteria, which consume the oxygen, and then use sulphates as an oxygen source instead, producing hydrogen sulfide. This is a very negative trend, since hydrogen sulfide is poisonous to all higher organisms, and high levels lead to the dead zones on the sea floor.
This situation is hugely problematic and a major climate change concern. The GeoLoop nanocavity concept is an excellent tool in addressing this. Oxygen nanocavities have neutral buoyancy and stay where they are deposited, supplying oxygen to the surrounding water volume over prolonged periods of time.
The ocean oxygenation and CO2 storage can be performed via the "Geoloop Column", a newly developed, multi-functional, ocean-based dome-system, designed to manage inter alia the following additional tasks:
- Ocean filtration (capturing of run-offs from land)
- pH stabilization – acidification prevention
- Nutrient redistribution
- Primary production stimulation (CO2 fixation enhancement)
- Biomass farming (within the Column)
- Biomass harvesting (within the Column)
- Fecal matter capture (within the Column)
- Strengthening of the natural ocean pumps (biological/physical/solubility/carbonate)
A full scale Geoloop Column prototype system has been installed (June, 2021) at a selected location in the Trondheim Fjord, Norway. This prototype unit is now undergoing an extensive test program, estimated to be finished by mid 2022). The key functionalities shall then be verified, and 24/7 monitoring and operating equipment installed.
The Geoloop Column is planned to be commercially available to customers in Q4 2022 subject to component deliveries. It is intended to be a platform vehicle for a number of applications, with significant market potentials.
The future is all-electric
Capturing CO2 is a necessary initial step to combat climate change.
The only permanent solution is to electrify the world. Electricity is by far the most efficient form of energy known to mankind.
What is needed, is a non-intermittent, 100% clean and renewable energy source. Ocean GeoLoop claims to have the solution, the e-Loop.
Powering Carbon Capture, Storage & Utilization is a start.
