Conventional turbines are often unsuitable for small-scale, medium-temperature heat sources – leaving most industrial waste heat unused or diverted to low-value applications like district heating. etavalve is developing a compact, containerized heat-to-power system based on a piston-driven Brayton engine with patented electro-hydraulic valve actuators – enabling efficient electricity generation even from fluctuating heat sources. Backed by strong technical expertise, key partnerships, and Letters of Intent from potential customers, etavalve is positioning itself to capture a significant share of the CHF 42.3 bn waste heat recovery market by 2030 – advancing energy efficiency and CO2 reduction goals.
