CNG Fuels, the supplier of biomethane fuel, and Waitrose, have announced that the supermarket group has introduced Europe’s most advanced fleet of CNG (compressed natural gas)-powered trucks with a range of up to 500 miles.
Ten new Scania-manufactured CNG trucks entered operation for Waitrose in January and will be used to make deliveries to the company’s stores in the Midlands and the North. They are the first in Europe to use twin 26-inch diameter carbon fibre fuel tanks which store gas at 250 bar of pressure to increase range from around 300 miles to as much as 500. It will allow them to always run entirely on biomethane, which CNG Fuels says is 35% to 40% cheaper than diesel and emits 70% less CO2.
The carbon fibre tanks, which are already in use in the US, offer significant advantages over the standard European set-up of eight steel gas tanks. The vehicles are half a tonne lighter, hold more gas and can cover a greater distance depending on the load being carried. They are quicker to refuel and easier to maintain.
Each of Waitrose’s new CNG trucks costs 50% more than one which runs on diesel, but will repay the extra costs in two to three years with fuel savings of £15,000 to £20,000 a year depending on mileage.
Its vehicles are likely to operate for at least five more years, generating overall lifetime savings of £75,000 to £100,000 compared with a diesel equivalent. Each lorry will save more than 100 tonnes of CO2 a year (versus diesel).
Justin Laney, general manager central transport for the John Lewis Partnership, said: “With Europe’s most advanced CNG trucks, we will be able to make deliveries to our stores without having to refuel away from base. Using biomethane will deliver significant environmental and operational benefits to our business. It’s much cleaner and quieter than diesel, and we can run five gas trucks for the same emissions as one diesel lorry.”
Philip Fjeld, CEO of CNG Fuels, added: “High pressure carbon-fibre fuel tanks demolish the ‘range anxiety’ concerns that have made many hauliers reluctant to move away from diesel to CNG. Renewable biomethane is far cheaper and cleaner than diesel, and, with a range of up to 500 miles, it is a game-changer for road transport operators.”
