RONDO ENERGY EUROPE LIMITED

Rondo Energy Europe Limited is a pioneer in electrified thermal energy storage, turning intermittent wind and solar electricity into a reliable, low‑cost supply of continuous industrial heat and power. Their flagship Rondo Heat Battery (RHB) charges for 6‑8 hours a day using renewable electricity, stores the energy in refractory bricks heated to 1 100‑1 500 °C, and discharges super‑heated air or steam 24 hours a day with over 98 % overall efficiency and a lifespan of more than 40 years.

The RHB is a drop‑in, modular solution that can be configured from 2 MWth up to more than 100 MWth, making it suitable for a wide spectrum of sectors—including food and beverage, cement, chemicals, textiles, steel, mining and direct‑air‑capture facilities. With unlimited charge‑discharge cycles, no degradation and zero emissions of NOx, SOx or particulates, the system offers a safe, fire‑free alternative to conventional fossil‑fuel boilers and even lithium‑ion batteries.

Backed by leading global investors and partnerships, Rondo already has 11 commercial developments and eight RHB deployments across five industries, totalling over 200 MWh of announced projects and 3 GWh of partnership capacity. The technology is already operating at scale, exemplified by the groundbreaking at Covestro’s Brunsbüttel site in Germany, where ten percent of the plant’s steam now comes from renewable energy via a
