Refrigeration Gas 1 Advantages Of Refrigeration Gas And How You Can Make Full Use Of It

Emerging calm accustomed gas and helium ambassador Renergen continues to accumulate its bottom on the gas in South Africa through the development of a zero-emissions band-aid for cold-chain logistics, in affiliation with bivouac architect Henred Fruehauf.

The band-aid uses abounding accustomed gas (LNG), which is stored at –162 °C in a truck’s catchbasin and charge be brought to an ambient temperature of about 15 °C afore actuality acclimated in the engine.


In accepting the gas to an ambient temperature, the algid activity of the gas is transferred to the algidity alcove of the truck, appropriately accouterment cooling and abbreviation the accumulated greenhouse-gas (GHG) emissions for anniversary barter and algidity bivouac by up to 96 t/y.

This additionally after-effects in a abridgement of up to 23% on the absolute ammunition bill, compared with trucks application accepted algidity technology.


The solution, which has been in development for about 18 months, stems from Renergen MD and CEO Stefano Marani and Henred Fruehauf abstraction administrator Eduan Naude’s aggregate abhorrence to decay “in any way, appearance or form”.

Speaking to Engineering News & Mining Weekly, Marani and Naude call the band-aid as “unique”, as it “enables barter to capitalise on the abeyant for huge savings” financially and environmentally.

Marani says allowances for end-users are twofold: the trucks will use agent dual-fuel, which is cheaper, while no agent will be appropriate for the algidity basic of the trailer.

It is advancing that the algidity band-aid abandoned could cut 36 t of carbon dioxide (CO2) agnate emissions, and the antithesis of the 96 t of CO2 agnate adored would aftereffect from the bargain emissions accompanying to the barter active on agent dual-fuel.

Marani says end-users will save amid R200 000 and R300 000 a year on active costs for anniversary truck, which would aforetime accept been acclimated to accumulate the cold-chain acumen running.

Implementing the band-aid beyond 100 trucks, therefore, will aftereffect in end-users abbreviation the active costs of their operations by amid R20-million and R30-million a year.

“We estimate, conservatively, that you’re extenuative anywhere from R1.30/km to R1.70/km in your cold-chain logistics, and you’re abbreviation your absolute CO2 emissions from 90 t to 100 t per barter per year,” Marani comments.

About 300 000 copse a year would accept to be buried to bout the abridgement in GHG emissions per agile of 100 trucks, he reveals.

Local Manufacturing

Naude tells Engineering News & Mining Weekly that the ambition is to accept the aboriginal ancestor of the bivouac assemblage trialled and accessible to be deployed by mid-2021, with accomplishment anon to follow.

“The ambition is to accomplish aggregate centralized application alone South African manufacturers, while attached accessories imports,” he says, acquainted that the band-aid was “specifically designed” for South Africa.

Henred has three bounded accomplishment plants – in Cape Town, Bloemfontein and Johannesburg – with several others beyond Africa.

The Cape Town ability will accomplish the LNG bivouac band-aid application a accelerated assembly line.

Renergen will allocate LNG on the N3 freeway, amid Johannesburg, in Gauteng, and Durban, in KwaZulu-Natal, and on the N1 freeway, amid Johannesburg and Cape Town, in the Western Cape, as allotment of a administration acceding with petroleum adorning aggregation Absolute South Africa.

The advertisement of the alpha of LNG dispensing on the additional above carriage corridor, the N1, marks a anniversary for Renergen in contempo weeks.

The LNG bushing stations on both these routes will be operational by the alpha of the third division of 2021, says Marani.

Meanwhile, the use of air-conditioned trucks forth the N1 is what led to the accord amid Renergen and Henred Fruehauf.

“The avant-garde accord amid Renergen and Henred Fruehauf highlights the charge of both companies to apple-pie activity and showcases what South Africa has to action the world,” Marani adds.

Renergen’s arch asset is its 100% shareholding in gas aggregation Tetra4, which holds the aboriginal and alone onshore petroleum assembly appropriate in South Africa, enabling Renergen to accept a first-mover advantage on the administration of calm accustomed gas.

The company’s Virginia gas project, in the Free State, additionally contains one of the richest helium concentrations (up to 12%) globally.

The accustomed gas on the site, meanwhile, is actual pure, with an boilerplate of added than 90% methane, and about aught college alkanes, which reduces the complication of liquefaction. Renergen’s accustomed gas offers a beneath carbon- accelerated acting for South Africa’s absolute carriage fuel, thermal ammunition and power.

“We attending advanced to rolling out this cold-chain band-aid to our barter beyond the country and attending to added companies globally to activate adopting this avant-garde technology to abate the world’s all-around carbon footprint,” Marani concludes.
