Zelk is diversified energy platform that provides low-cost hydrogen from industrial waste heat and biomas, offering an opportunity to stabilize the grid with clean power for cities and transport systems.

Using electrolysers to produce green hydrogen via solar and wind power is too costly and inconsistent to be viable at scale and meet demand over the next decade.

Zelk brings together the latest technology for steam methane reforming with waste heat and provides co-combustion engine technology that provides an immediate market for the hydrogen produced for our project partners.

Our team has over 100 years of collective experience in combining entrepreneurial strategies to societal problems–from energy to recycling to transport.
