Saltlagring

MOSS is a new type of cost-efficient molten salt storage based on hydroxide salts, which will make molten salt storage commercially viable. It is based on a patented technology on how to control corrosive salts and use their superior characteristics for giga-sized storage. The initial use case will be in combined heat-and-power production, and we expect to be able to build the first commercial plant in 2024. In compact storage tanks, MOSS can store 1 GWh of energy (or more) and use this to even out daily peaks in consumption and to store for up to 2 weeks to bridge periods of weak wind. For each 1 GWh storage plant in operation, we will deliver annual C02-reductions of 32,000 tonnes. With several plants in operation this will be a major contribution to meeting climate targets nationally and internationally.

This project builds upon the achievements of the successfully concluded ‘MOSS’ and ‘Seacore’ EU Regional Fund projects and will:

• Finalise the design of all subsystems to function in sync with the novel chemistry control system developed by the partner, Seaborg
• Test and validate sub-systems and components and their scalability
• Demonstrate the world’s first energy storage facility based on inexpensive hydroxide salts

• Present a case study for implementation in the asset portfolio of one of the partners – to be a guide for other district heating companies
