At the beginning of 2021, the energy storage company SaltX Technology began collaboration with LuleKraft, Luleå Energi and the metal research institute Swerim, to reduce CO2 emissions for the industrial sector in the region. A pre-study has been carried out, that clearly shows that SaltX energy storage can increase energy efficiency and lower climate impact for the steel industry. The industry and energy actors in the region have decided to further investigate future energy demand and supply needs. As a consequence of this new direction, the planned pilot plant will be postponed. Instead, SaltX intensifies its work for the steel industry's green transition.SaltX’s solutions for long- and short-term energy storage make it possible to utilize surplus energy from the steel manufacturing process and reduce global CO2 emissions. Swerim works intensively in this field and sees many future possibilities for this technology.SaltX and Swerim are now focusing on a further study on energy storage for the steel industry in Sweden. The dialogue about Luleå City's future energy system with LuleKraft and Luleå Energi, will continue with the ambition of resuming the cooperation as the new conditions are clarified.SaltX Technology develops and sells patented energy storage solutions. SaltX works to develop and offer sustainable technology and solutions that benefit customers, the climate, and society.Swerim is a leading metal research institute that conducts industrial research and development around metals and their path from raw materials to finished products. The organization wants to strengthen the industry's competitiveness through increased product quality, higher resource efficiency, and more sustainable manufacturing processes. Its vision is a fossil-free and circular industry.
