Caltex taps solar PV, so it can pump more diesel at remote fuel stations

Caltex uses solar and battery storage to power portable diesel pumping stations – an “environmentally friendly” initiative to supply 24-hour diesel fuel in remote WA.

Australian oil major Caltex has built what it claims to be the world’s first “portable solar-powered diesel fuel outlets”, designed to provide easy, 24-hour access to diesel fuel to trucks in remote parts of Western Australia’s Pilbara region.

Caltex Australia’s diesel refuelling sites at Tom Price and Onslow, both more than 1300km from Perth, are not connected to mains power, instead using solar and battery storage technology to drive the pumps.

The stations will be unmanned, offering diesel 24 hours a day via a card payment system.

The company said in a statement on Monday that it had pioneered the “environmentally-friendly initiative” to further extend the reach of its National Truck Network – the largest truck refuelling network in Australia, comprising 200 dedicated truck stops and 300 truck-friendly sites across the country.

Whether using clean energy to provide around-the-clock access to heavily polluting diesel fuel can actually be described as “environmentally friendly” might be open to debate, but it is at least a step in the right direction by a company whose primary business is in fossil fuels.

According to Caltex network development manager WA, Leon Calvetti, the biggest challenge of supplying diesel fuel in remote parts of Australia isn’t about logistics, but about remote energy supply, as well as staffing.

“The obstacle is powering the pumps so the fuel can get into the customer’s tank – it’s very expensive and inefficient to run a generator when there are only a handful of customers every day.

“By creating what we believe are the world’s first fully solar-powered fuel facilities, we can efficiently provide diesel in some of the most remote locations of Australia,” he said.

A further environmental benefit of the portable diesel pumping stations is that they can be easily decommissioned when no longer needed in any one particular spot.

“If that happens we can simply relocate the entire facility to a new part of the country, as everything on the site is easily transportable by truck,” Calvetti said.

“The whole design is tailored to Australian conditions, given the abundant sun and the long distances between service stations.”

Presumably, when Australia’s truck transport fleets switch to electric vehicle technology, they might not be be needed at all.

    Well you may complain about the CO2 emissions from diesel, for the moment it is one of the only fuels which is able to fuel transport in the outback. All credit to Caltex for this development.

      Actually diesel has a problem as NO2 are not exactly good for humans.

        NO2 isn’t much of an issue in the outback though.

        In cities it’s a tradeoff with internal combustion engines. Diesel means less CO2 and CO but more of some other nasties when compared to petrol.

    Looking at the panels it looks like 21 possibly 250v so expected outcome is a 5 KW plus system which will deliver possibly average of at least 23 to 25 KwH per day.
    As to what type of pumps they have perhaps about 1 Kw then this will be able to work as heaps of power during daylight hours with battery back up trimming off the excess there is no reason this will not work as the amount of power being created exceeds the demand not a hard exercise in utilisation of solar power by a long shot.

    A 5kW solar diesel hybrid plant was installed in 2001 at an Indian Oil petrol station near Gaya to pump fuel when grid electricity failed. The project was executed by Advanced Energy Systems, a Perth based Australian company. So, this project is not world’s first.

    if there was grid connectivity out there, I bet your life they would use that instead.
