About
Founded in 2003, Tidetec is a private headquartered in Oslo, Norway with approximately 10-50 employees specializing in Tidal.
Tidetec is an Oslo-based technology SME founded in 2003 and led by CEO Arne Kollandsrud. The company has developed a patented turbine solution specifically designed for tidal range energy schemes. The core innovation is a turnable turret mechanism that houses a propeller-type turbine, enabling optimal efficiency in both tidal directions. The technology consists of three main components: a rotating turret with turning mechanism, turbine, and caisson. Tidetec's solution addresses key techno-economic barriers in tidal energy commercialization, offering 20-30% higher efficiency than existing tidal turbine technologies and improving pumping efficiency for lagoon production schemes. The company has received EU funding through the REALIZE project, Green Offshore Tech Phase 2 grant (€30,000), and Canadian patent protection. Tidetec is preparing pilot projects and has been selected to present at major industry events including ESTEC Amsterdam 2024.
