The European energy system is in the midst of a green transition, where battery energy storage systems will play a central role, and we need you to make it happen!
Capture Energy, a fast-growing Swedish company founded in 2023 and with 38 employees currently, aims to become a market leader in the Nordics in providing battery energy storage systems (BESS) for energy flexibility services - a market that is expected to experience significant growth in the coming years. With innovation at our core, we're building the digital infrastructure that powers the clean energy transition - starting with our next-generation platform, Capture Cloud.
As a small company today, we are able to operate very differently compared to the larger players on the market, which gives us a great competitive position. We are committed to bringing good energy to every setting where we operate: from our customers, partners, to our employees.
