Exergyn Ltd

clock • 1 min read

Exergyn has developed an engine that runs on hot water (80C-120C). Technically, it converts low-grade waste heat (LGWH) to power - electrical or mechanical.

It is a solid-state reciprocating engine, employing nitinol (which expands & contracts at different temperatures). Crucially, we are focused on being the first commercial solution to the low-grade waste heat problem.
