New hydrogen dual fuel engine tech could cut emissions and extend vehicle range: Molecular Energies-owned firm plans Paraguayan truck roll-out

A Molecular Energies-owned company says its hydrogen dual fuel technology could cut heavy-duty diesel engine emissions while also increasing vehicle range, as it plans a Paraguayan roll-out for 2024.

Dual Fuel Limited (DFL) – a wholly owned subsidiary of Molecular Energies’ alternative energy division Green House Capital Group – earlier this year (2023) carried out trials of its hydrogen injection technology.

Conducted by Helical Technology, the trials reportedly confirmed that around 20% hydrogen can be safely introduced into a heavy-duty diesel engine resulting in a “proportionate reduction” in emissions. Furthermore, DFL said the solution could “significantly” extend the range of vehicles.

H2 View has reached out to DFL for confirmation on how bigger percentage of emissions could be cut by the solution.

The testing evaluated the engine and test cells, running the engine on diesel alone and then progressively introducing hydrogen until the fuel entering the engine become “disproportionate to its power output.”

DFL now plans to undertake a test of the dual fuel solution in a live “rolling road environment” in Q1 2024, which is hoped to complete the calibration of the system’s software.

Upon completion of the trials, DFL hopes to deliver its first retrofits to customers in Paraguay in Q3 20434, with its first customers “already identified.”

The company says the retrofit deployments will be supported by the supply of 100% green hydrogen generated by Green House’s G-Mobility.

Christopher Raggett, CEO of Green House said DFL’s technology has a “significant advantage” over other hydrogen mobility solutions.

“It can use existing vehicles at a modest retrofit cost, avoid having an expensive hydrogen refuelling network whilst at the same time importantly reduce carbon emissions as a transition to Net Zero,” he said.

Green House plans to go through an IPO in Q1 2024.

With no active railway network, Paraguay uses fleets of around 75,000 long-range heavy-duty trucks and 3,000 barges for its logistics. Molecular Energies, through its current and historic network, as well as its sister company Atome Energy, says it is “particularly well” positioned to gain traction in the Paraguayan market.

Atome is currently undertaking a green hydrogen-based fertiliser project in the South American nation. The company plans to install 145MW of electrolysis to produce the green hydrogen feedstock.
