ULEMCo signs MoU with ENGV Pty Ltd to open the market for hydrogen conversions in Australia

UK-based ULEMCo signed an exclusive MoU with ENGV Pty Ltd to collaborate on developing a market for its hydrogen dual fuel technology in Australia. The scope of the agreement extends across Australia and into commercial vehicles, particularly heavy-duty applications like refuse collection, urban trucks, buses and prime movers.

By using hydrogen to displace diesel directly in the engine, ULEMCo’s dual fuel technology H2ICED enables vehicle owners to reduce their carbon emissions by up to 40%, as well as offering a practical solution that is immediately available.

Additionally, by providing a low-risk option for fleetwide conversion, it can provide demand for investment in hydrogen refueling infrastructure that can accelerate the overall take up of hydrogen technologies globally.

ENGV developed and now operates Australia’s first public hydrogen refueling station (HRS) in Canberra, with plans to support the growth of industry by the deployment of best-in-class HRS solutions for both public and depot-based refueling.

The existing diesel fleet replacement cycle in Australia is generally between 7-20 years. We see the unique ULEMCo technology as providing a hydrogen load for infrastructure investment whilst also delivering immediate CO2 and tailpipe emission reduction benefits. ENGV has many years of experience with the development and deployment of gas heavy vehicles in Australia. We were previously involved with LNG and CNG truck installation and operation in Australia. We see this technology as a natural extension of our core business and competencies.

We were discussing hydrogen ICE emissions of NOx in another thread, and apparently emissions are substantial unless either more air is used than needed for combustion, which unfortunately reduces power, or a more sophisticated design is used with water injection, which it was claimed more or less eliminate them altogether.

So I had a look on the ULEMco site to see what they had to say about NOx, and this is what I found:

' Other conclusions from the work were that tail pipe emissions in a number of specific applications such as refuse trucks were significantly better than the EURO 6 base vehicles, with the NOx emissions reduced by between 29-85% across the range of cycles tested. If deployed full time, the vehicles would not only save carbon but also provide improvements to local air quality. At least 96% of the hydrogen used in the trial came from on-site electrolysis from renewable electricity.'

So nothing really specific on the technological choices employed, but interesting just the same.


Hydrogen combustion produces NOx



Yeah, but how much of them?

The discussion was indeterminate in the other thread, and techniques to minimise them show, but not in enough detail to put numbers and costs on them.


Do the research


EGR brings hydrogen down to gasoline level NOx


I watched a webinar presentation from a German company developing the same thing, H2 conversions for commercial vehicles. The top question asked was - NOx. They said existing catalytic converter technology will work, so there will be no increase in NOx over diesel. Since Dieselgate I expect the regulators at least here in Europe will be hot on that and the converters have it as a top priority.



This is a discussion forum. If you don't want to be helpful, just show off how knowledgeable you are, then you are wasting everyone's time, as well as being absurdly unpleasant.
