Behind the scenes of the innovations that created Rehlko’s 1MW Hydrogen Fuel Cell standby generator—the industry’s first commercialized fuel cell for mission-critical industries.

In 2023, Rehlko supported polar explorer Robert Swan's Undaunted Expedition across the Antarctic landmass to the geographic South Pole with our off-grid sustainable power system.

Renewable hydrotreated vegetable oil (HVO) fuel can power our diesel engines and generators without complications - and with the same energy and reliability you expect.

Best-in-class industrial generators, uninterruptible power systems, complex microgrids, and future-forward solutions for everything from data centers to hospitals.

Robust, innovative power solutions from combustion through hybrids and electrification, to get tough jobs done well.

Commercial-grade home backup generators that ensure quiet confidence that your home will never lose power when the grid goes down.
