A breakthrough technology that allows engines to run on excess hot water, decreasing companies' environmental impact while increasing profitability.

After noticing the amount of energy wasted as hot water, Exergyn began finding a way to harness that energy for productive, efficient use. Exergyn has developed an innovative, easy-to-use solution to deliver cost-effective electricity where and when it is needed — without emissions. Until now, there has been no commercially feasible way for hundreds of thousands of companies worldwide to make use of the enormous quantities of wasted hot water (c.90°C, or low-grade waste heat "LGWH") that they produce. The Exergyn Drive™ enables companies to improve energy-efficiency, increase profitability, and deliver environmental CSR objectives by converting LGWH to electricity. If the Exergyn Drive™ was used in all its possible global applications, a 1.2 percent cut in global carbon emissions could be achieved. Exergyn is working toward this goal.
