Energy Dome

Danish clean energy major Ørsted A/S (CPH: ORSTED) to probe the potential for constructing a 20-MW/200-MWh energy storage facility at one of its sites, utilizing the CO2 innovation of Italian long-duration energy storage firm Energy Dome SpA.

Italy-based energy storage solution company Energy Dome has revealed that it has signed a memorandum of understanding (MoU) with Denmark's Ørsted, which is a global leader in offshore wind. This teamwork is to run a feasibility study on the implementation of a 20 MW/ 200 MWh energy storage facility using Energy Dome's CO2 battery innovation for Ørsted sites.

Italian start-up Energy Dome has actually launched the first demonstrator project of its carbon dioxide-based energy storage space remedy, a 4MWh system in Sardinia, Italy, while also revealing Series B plans.

Carbon dioxide gets a workout in this brand-new long duration energy storage space system that can deliver wind or solar energy 24/7.

Energy Dome's emission-free energy storage space technique utilizes carbon dioxide in a closed loop charge/discharge cycle that can store and also dispatch renewable resource onto the grid over durations from four to 1 day.

In charging mode, the CO2 is drawn from an atmospheric gas-holder, the Dome, compressed and then saved under pressure at ambient temperature level in a high density supercritical or liquid state. When energy needs to be launched, the CO2 is evaporated and also expanded into a generator, and then returned back to the atmospheric gas-holder, prepared for the following billing cycle

The battery is claimed to keep energy at about fifty percent of the expense of keeping with comparable sized lithium-ion batteries. Unlike lithium-ion batteries that experience considerable performance degradation during their 7-10 year layout life, the CO2 Battery keeps its efficiency throughout its expected 25 year functional life, claims the company.
