MIT startup says it can turn diesel trucks into cheaper hydrogen haulers; see it at Disrupt

Diesel truck conversion to hydrogen is now 13% cheaper to operate than standard diesel.

MIT startup LNK Energies has developed a method to convert existing diesel trucks into hydrogen-powered vehicles, aiming to reduce operating costs and pollution. Their technology uses liquid organic hydrogen carriers (LOHCs) which store hydrogen chemically, allowing it to be transported and dispensed like traditional diesel fuel. A key innovation is a miniaturized reactor, roughly the size of a mini-fridge, that can be installed on-board a truck to release hydrogen as needed. This on-board release eliminates the need for high-pressure compression, which is energy-intensive and costly. The released hydrogen can be used in modified internal combustion engines or fuel cells. LNK Energies claims their converted trucks will have a 13% lower total cost of ownership compared to diesel, even without government subsidies. They plan to demonstrate a larger-scale version of their reactor in a commercial truck within 18 months.

LNK Energies' approach bypasses the significant infrastructure challenges associated with traditional hydrogen transport and storage. By using LOHCs and on-board reactors, the company leverages existing diesel fueling stations, drastically lowering the barrier to entry for hydrogen adoption in heavy-duty trucking. This could accelerate the transition to cleaner fuels by making it more accessible and economically viable for operators who are currently grappling with volatile diesel prices and increasing environmental regulations.

The startup's miniaturized reactor technology is critical, as it makes on-board hydrogen generation feasible for trucks. This contrasts with previous LOHC applications that focused on stationary infrastructure. If LNK Energies can scale its production and achieve its cost targets, it could disrupt the heavy-duty transport sector by offering a compelling alternative that doesn't require a complete overhaul of the existing fueling network, potentially impacting traditional diesel engine manufacturers and established fuel suppliers.
