A collaborative research initiative to trial and test hydrogen use in a high-pressure direct injection (HPDI) fuel system for Scania's internal combustion engines.

High Pressure Direct Injection fuel systems designed to run on hydrogen, offering advantages for heavy-duty vehicles in terms of performance, emissions, and cost-effectiveness.

A high pressure direct injection system that enables internal combustion engines to run on alternative fuels such as liquefied natural gas, biogas, and hydrogen.

An internal combustion engine designed for heavy-duty vehicles that runs on hydrogen fuel. It is claimed to offer increased performance and a lower-cost pathway to CO2 reduction.
