Hydra Energy is the world's first Hydrogen-as-a-Service (HaaSTM) provider for commercial fleets looking to reduce costs and emissions today with limited risk and no up-front investment. The company's innovative approach sources green hydrogen from leading chemical partners and provides clean fuel to fleets at below-diesel prices, enabling a rapid and economic transition to cleaner trucking.

In exchange for long-term, discounted fuel contracts, Hydra quickly converts semi-truck fleets to a proprietary hydrogen injection system helping operators optimize truck performance, fuel efficiency, and emissions reduction regardless of payload and weather.

With Hydra Energy's retrofit technology, hydrogen tanks and gas handling components are installed behind the truck cab. This is where the hydrogen is stored. Each truck has 30kg of hydrogen on it. A hydrogen injection manifold is installed in line with the air intake, blends hydrogen and air before entering the engine block. This is how hydrogen is injected.

A dedicated, secondary controller is installed behind the truck dashboard, which controls hydrogen flow. When the driver presses the pedal, it signals the master OEM computer, which the secondary Hydra controller intercepts.

It then injects the required hydrogen needed to produce 40% of the required power demand directly into the air intake, eliminating the need to modify the engine block. By using existing semi-trucks, and Hydra's Hydrogen-as-a-Service infrastructure, you can have hydrogen today. There's no need to wait for entirely new vehicles and fueling infrastructure to be designed and built at some point in the future.

With as high as 40% diesel displacement, Hydra trucks can run up to 1,000 km/a day burning 24 kilos of hydrogen, even with the heaviest payloads and in the heart of winter. There's no need to worry about range either, as Hydra trucks can seamlessly switch to just running on diesel if the hydrogen runs out.

Hydrogen technology for large internal combustion engines enables seamless switchover without losing fuel efficiency, range, power, torque, and payload capacity. I invited Jessica Verhagen to share the story behind the company and how they plan to propel low-carbon hydrogen trucking solutions.
