Coolbrook
RotoDynamic technology for electrifying high-temperature industrial processes — renewable electricity to 1700°C with zero operational CO2. The first commercial-scale RotoDynamic Heater is deployed with Adani's Ambuja Cement; the FutSteel project with SSAB and Business Finland (6/2026) extends it to steel: blast-furnace processes, reheating, hot-stove pre-heating, DRI and hydrogen-based steelmaking.

How this row was decided
Every row on this map is checked by hand against the trade register and the company's own material, and placed in the sector that best describes its business or its technology. Service firms and consultancies are left out, however advanced the technology they work with — the test is where the revenue comes from. Only funding figures the company or its investor has published are shown. The full rules are on the landscape ↗
