Making maritime mobility sustainable, not by 2030, not by 2050, but right now!

We provide affordable and readily installed marine engine retrofit kits to enable hydrogen combustion, providing savings on fuel and maintenance costs while eliminating the environmental impact of navigation

More than a solutions provider, we are an ecosystem developer

Reinforcing the operational independence of maritime and riverside communities is our credo. We leverage and cultivate the existing skill-sets and knowledge-base of community stakeholders around the use of their internal combustion engines.

In addition to providing our engine retrofit kits, we will teach you how to install and maintain components yourself as well as how to work with hydrogen safely. And if you’re wondering where to source hydrogen fuel, our partners are here to ensure longterm availability.
