Accelerating the Transition
To the Hydrogen Economy
Our Story
Hydrogen On Demand Technologies is an early-stage Silicon Valley-based original equipment manufacturer (OEM) that provides sustainable hydrogen solutions to bring about a sensible transition towards clean energy, resulting in a triple bottom line improvement for diesel fleet operations and our planet.
Our Diesel Hydrogen Assist Technology (D-HAT™) generators are independently verified to improve the combustion efficiency of large diesel engines, thereby, increasing fuel mileage, decreasing engine maintenance, and significantly reducing harmful diesel emissions.
The Problems We Solve
Hydrogen is not only the universe’s most abundant element, it’s also the world’s cleanest source of energy. For decades hydrogen has held the greatest promise for a clean energy future. But its potential has been throttled by the practicalities of production, storage and distribution.
-
Expensive to produce:
Producing pure hydrogen currently remains a highly centralized and expensive process that requires more resources to produce than it returns in energy value.
-
Difficult to store:
Formerly, when stored as a gas, hydrogen broke down most containers. Stored as a liquid, it requires expensive cryogenics and intensive safety infrastructure.
-
Expensive to transport:
Centrally produced in volume, today’s hydrogen must be transported to the infrastructure and compressed in tanks from which it is ultimately consumed.

Our Vision
We’re here to bring about a sensible transition from a hydrocarbon economy to a Hydrogen Economy through innovative fuel solutions to meet existing and future global demands.
Our Mission
We are an environmentally impactful company whose mission is to improve environmental outcome of diesel operations while transitioning into the future of zero emissions operations.
