# SeaPattern > SeaPattern is a Swedish cleantech company, founded in 2020 out of research > at Linköping University. It builds floating, plug-and-play turbines that > mount downstream of existing hydropower plants and capture kinetic energy > in water that has already passed through the plant — no new dams, no new > environmental impact. SeaPattern states the typical uplift as 1–3 GWh per > plant per year. The system has been field-tested since 2022 at Svartåfors > together with Tekniska Verken, delivering increased production so > far. SeaPattern has raised €6.5M+ in funding, including a €5M private > round led by Industrifonden, and partners with Actemium (VINCI Energies' > industrial brand) for turbine manufacturing. Headquarters: Linköping, > Sweden. ## Language note The public site's primary language is English, served at the root (`https://www.seapattern.com/`, ``). Complete Swedish and German versions of every page live under `/sv/` and `/de/`, using the same slugs (e.g. `/losning` ↔ `/sv/losning` ↔ `/de/losning`, with `` set accordingly). The links below point at the English pages; each entry notes its Swedish and German counterparts. ## The system: four parts (from /tekniken) - **Drone scan** — drone survey of flow speed and water level; establishes a plant's exact potential before any decision is made. - **Turbines** — floating turbines with sensors and telemetry that capture the kinetic energy in water already past the plant. - **Anchoring** — mounted in the plant's existing outflow channel, no new dams or streambed work; each turbine's position is adjusted for maximum energy capture. - **Grid connection** — converts the captured energy to grid-ready power and connects it to the plant's existing grid connection, or stores it in battery banks. ## Key facts (as the site states them) - Founded 2020, out of research at Linköping University. - Headquarters: Repslagaregatan 19, 582 22 Linköping, Sweden. - Typical uplift: 1–3 GWh per plant per year. - Pilot: field-tested since 2022 at Svartåfors together with Tekniska Verken; increased production delivered so far. - Manufacturing partner: Actemium (VINCI Energies), strategic partnership announced 2025-11-25. - Funding: €6.5M+ raised in total, including a €5M private round led by Industrifonden. - Team: about 20 people, 6 nationalities, 4 PhDs. - Addressable market (as stated on /investerare): 211 GW of installed hydropower across roughly 22,000 plants in Europe. - Contact: contact@seapattern.com. - LinkedIn: https://www.linkedin.com/company/seapattern/ ## Pages - [Home](https://www.seapattern.com/) (also /sv and /de) — company overview: what SeaPattern builds, the 1–3 GWh/year uplift claim, and entry points to the rest of the site. - [Solution](https://www.seapattern.com/losning) (also /sv/losning and /de/losning) — the three use cases for the system: energy utilities, defense, and off-grid power. - [Technology](https://www.seapattern.com/tekniken) (also /sv/tekniken and /de/tekniken) — how the four-part system works: drone scan, turbines, anchoring, grid connection. - [Impact](https://www.seapattern.com/impact) (also /sv/impact and /de/impact) — the environmental case: no new dams, no new intervention in the waterway, impact validated by Swedish university research. - [Investors](https://www.seapattern.com/investerare) (also /sv/investerare and /de/investerare) — market thesis (22,000 hydropower plants / 211 GW in Europe), traction, board, and financial reports. - [Careers](https://www.seapattern.com/karriar) (also /sv/karriar and /de/karriar) — open roles and culture at the Linköping-based deeptech team. - [Team](https://www.seapattern.com/team) (also /sv/team and /de/team) — the ~20-person team across six nationalities: board and leadership. - [About us](https://www.seapattern.com/om-oss) (also /sv/om-oss and /de/om-oss) — hub page linking to Team, including the company timeline from the 2020 Linköping University origin to today's industrialization phase.
