LNK Energies Says Hydrogen Retrofit Cuts Class 8 Truck Costs 13%
MIT startup LNK Energies says its liquid hydrogen carrier can retrofit Class 8 diesel trucks, cut ownership costs 13% and bypass 11,000 psi compression.
Summary
MIT startup LNK Energies says converting existing Class 8 diesel trucks to hydrogen can cut total ownership costs 13%, reduce pollution and limit exposure to fuel shocks linked to the war in Iran. Its liquid organic hydrogen carrier, or LOHC, stores hydrogen in liquid form inside conventional fuel tanks and uses diesel-style pumps, avoiding dedicated hydrogen stations and compression above 11,000 psi, or 800 bar, about 800 times normal air pressure. Hydrogen interests long-haul operators because refueling is faster than charging massive truck batteries, but conventional pressure tanks are large and costly.
LNK reduced the reactor that releases hydrogen from shipping-container scale to mini-fridge size, allowing onboard installation. A lightly modified internal combustion engine can burn the hydrogen and supply waste heat to the reactor, while fuel cells could power electric motors without combustion emissions. CTO Alexis Huynh and co-founder and CEO Sayandeep Biswas have demonstrated the system on a lawnmower engine and plan a commercial-truck installation within 18 months. Although converted trucks will cost more upfront, LNK projects undercutting diesel at $6.50 per gallon after producing 50 to 100 trucks, without subsidies. The company will pitch at Startup Battlefield during Disrupt in San Francisco from October 13 to 15, as governments release stockpiled fuel following recent record diesel prices.
Positives
- LNK projects 13% lower total ownership costs for converted Class 8 trucks than diesel models.
- The mini-fridge-sized reactor replaces LOHC systems previously as large as shipping containers.
- Liquid storage eliminates compression above 11,000 psi and can use conventional fuel tanks and diesel-style pumps.
- Fuel cells could eliminate combustion emissions, while modified engines offer operators a less disruptive conversion path.
- LNK expects to beat diesel at $6.50 per gallon after producing only 50 to 100 trucks, without subsidies.
Risks & concerns
- Only a lawnmower engine has been powered so far, leaving commercial-truck performance unproven.
- The first commercial-truck installation remains 18 months away.
- Converted trucks will carry a higher upfront price despite projected operating savings.
- The 13% ownership advantage and $6.50-per-gallon threshold are company projections, not results from deployed fleets.
- Recent record diesel prices and the war in Iran show operators remain exposed to volatile fuel markets during development.
