Dual fuel
Hydrogen / Diesel dual fuel conversion
h2ec is seeking heavy vehicle partners who are looking to meet near term emissions reduction targets.
h2ec will convert existing heavy vehicles to run “dual fuel” using a blend of renewable green hydrogen and diesel. We will supply the hydrogen and re-fueling facilities, achieving ~30% average CO2 emissions reductions for our partners.
How does it work?
Gaseous hydrogen storage tanks are mounted behind the cab or side mounted on the chassis, and hydrogen is fed via a control and safety system into the engine air intake, pre-mixing hydrogen and air prior to combining with diesel in the combustion chamber. A supplementary engine control unit regulates the rate of hydrogen flow maintaining original vehicle performance. The vehicle can still run on 100% diesel – no hydrogen – with no impact if required, for example if hydrogen is unavailable or the tanks are empty.
Why dual fuel?
h2ec believes this “hybrid” approach makes it a perfect stepping stone towards a future where 100% hydrogen heavy vehicles are available in Australia and competitively priced. It allows operators to partially decarbonise their fleet – around 30% carbon reduction on average – whilst also safely integrating hydrogen into their operations for when zero emission hydrogen vehicles arrive in larger numbers.
What type of truck can be converted?
Much of the existing heavy vehicle fleet in Australia can be converted. Typically, the best use case is for prime movers, but rigid trucks are also in scope for conversion. The system can be used with all the major OEM vehicles seen in Australia including Volvo, Scania, Kenworth, Mack and Mercedes.
Is it safe and what will it do to truck performance?
We know that safety and vehicle performance are top of mind for all truck operators and h2ec and our technology suppliers can work with interested operators to address any concerns. The technology is already available and proven internationally and has undergone rigorous testing. The impact on payload is small, if any at all (additional weight < 1 tonne) and axle weight constraints are typically unaffected.
How to get involved
h2ec is seeking interest from partners to undertake conversions of existing heavy vehicles and to work with us to map out key routes for decarbonisation and identify locations for hydrogen refuelling stations. If this sounds like you, please complete our short survey and we’ll be in touch to provide further information.
