Nordural and Ocean Geoloop cooperate on carbon capture

Nordural has signed a Letter of Intent (LoI) with Ocean Geoloop for carbon capture at the Grundartangi aluminium smelter in Iceland.

The project aims at reducing Iceland’s carbon emission by around 10 % by deploying Ocean Geoloop’s carbon capture solution. “We are proud to announce this agreement with Nordural, aiming to reduce carbon emissions significantly by deploying our disruptive carbon capture solution. The end-of-pipe technology is planned to be assisted by the E-Loop, a horizontal hydropower unit, enabling electricity production utilizing the CO2 from the aluminium process resulting in a self-energized carbon capture solution at Nordural,” says Odd-Geir Lademo, CEO of Ocean Geoloop.

Ocean Geoloop

develops, pilots and commercializes multifunctional environmental technologies for carbon capture, utilization and storage. The Geoloop carbon capture solution is characterized by several unique capabilities, as the CO2 separation is 100 % clean, can capture 100 % of the CO2, and has no need for special adaptations based on the type of flue gas. The carbon capture process is expected to be assisted by the E-Loop, a proprietary, horizontal hydropower unit, enabling electricity production from low quality heat sources.

The E-Loop can produce electricity from low grade (below 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 and opex costs.

The technological 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 1 % to more than 50 %, can furthermore be handled in an economically viable manner.

Thanks to the use of hydro energy, Nordural produces aluminium with one of the lowest CO2 footprints in the world. With OGL, Nordural, a wholly-owned subsidiary of Century Aluminum, has the ambition to become a carbon neutral aluminium producer.
