Hydrogenation-Derived Renewable Diesel [HDRD]

By Anthony Crawford |

Not sure about Biofuel or specifically, biodiesel? Neither are we, but HDRD could end up as the new clean fuel that can rid the planet of fats and vegetable oils by turning them into a diesel fuel.

Of course, biodiesel isn’t exactly new. Scientists E. Duffy and J. Patrick carried out the process of Transesterification of a vegetable oil in 1853 long before Rudolf Diesel’s first diesel engine ran on its own power using nothing but peanut oil in 1893.

HDRD is what is known as a ‘second-generation biodiesel’ because it refines fats and vegetable oils in a standard oil refinery. It can also use the same pipelines, petrol stations and the road transport system as conventional diesel.

Not only will HDRD drastically reduce CO2 emissions due its ultra-low sulphur content, provided the production process relies on feedstocks, performance and economy should be excellent given the fuel’s high cetane number (diesel’s combustion quality) of between 55-60.

That cetane rating is much higher than today’s low-sulphur diesel fuel and has far better lubricating properties and offers reduced wear on the fuel system.

Clearly, biofuel has some excellent properties, just ask Peter Bethune, who piloted the spectacular earthrace boat around the world running only on 100 percent biodiesel.

It all sounds great, but until our petrol stations can offer a ‘clean fill’ experience for drivers as well as plenty more diesel bowsers in plenty more stations, then I doubt the punters will be all that interested.

    There are so many Alternatives out there such as CNG, LPG Biodiesel etc, but us Aussies dont seem to care or even know about them. Why Arent we adopting all these clean fuels? I for one would love a large diesel car, but no one offers one at a competitive price.

      It’s not that we don’t care or know about them Shak, it’s that there isn’t sufficient demand from the market to justify all the money spent on infastructure to develp them here.
      Skoda Superb diesel is reasonably affordable for a large car.

      LPG is awesome, a well tuned liquid phase injection LPG engine can provide more torque than petrol whilst providing similar L/100km figures.

      It has the concentrated charge and cooling benefits of direct petrol injection but it’s cheaper.

    Shak:

    Most constituents of the ‘Australian’ car are developed and refined overseas. The local publically funded incarnations of international cartels cannot afford to develop diesels and thus we are laboured by mutations such as Toyota hybrids. Sad.

    My brother used to close last shift at Maccas. He would have to clean the grease trap. Awful

    now that stinky grease might be worth something.

    Mc BioDiesel?

      Oh, great, so now everytime I fill up with fuel I’ll get asked whether I want fries with that?

      • Martin

        I’m not complaining. haha!

    100 percent biodiesel was available here in SA at SAFF (fully licenced for it), however that has since been discontinued as it was sold off.

    In this article, I don’t think they are referring to used oil. Used oil, both vegetable and petroleum based, already is utilised as a fuel for industrial founderies and kilns. The oil is cleaned beforehand, and is still cheaper than gas and other energy sources for these kilns and founderies. Food oil is too contaminated with food scraps and water (believe it or not) in its normal state to put straight into an unmodified refinery.

    LPG absolutely stinks! Petrol smells ok. That’s one of the main reasons why I didnt get my car fitted with a LPG conversion.

    The natural gas from my kitchen stove doesnt stink, it smells like a match.

    Lets replace LPG with LNG!!!
