SBL Automotive has announced a significant milestone: the bi-fuel evolution of the LEVC TX is now available for vehicles licensed by Birmingham City Council.

This development marks a big step in further reducing emissions and operating costs for taxi drivers in the city. The new system enables the LEVC TX to run on either LPG or biopropane, instead of traditional petrol.

This change offers notable environmental benefits, with a 10% reduction in net CO2 emissions when using LPG and an impressive 99% reduction when using biopropane. SBL Automotive also claim operators can expect a 20% or more decrease in operating costs. As production volumes of biomethane and biopropane increase, further savings are anticipated.

The initiative extends the fossil fuel-powered range extender engine of the TX and VN5 to use compressed natural gas (CNG), biomethane, LPG, and biopropane. These fuels serve as drop-in replacements, requiring no further modifications to the vehicle.

The bi-fuel system utilises Prins Alternative Fuel Systems VSI-3 hardware, including fuel tanks, bi-fuel ECU, gaseous fuel injectors, and specific regulators and vaporisers, all compliant with relevant safety standards. For CNG/biomethane, a pressure regulator is used, while LPG/ biopropane systems use a vaporiser. The system's design enhances the vehicle’s operating range significantly - by approximately 90% for LPG/ biopropane and 70% for CNG/ biomethane, thanks to the retention of the original petrol tank.

These lower-carbon and renewable fuels are available today, offering a practical solution for reducing emissions from internal combustion engines. The bi-fuel evolution allows existing petrol or diesel engines to transition seamlessly to these alternative fuels, ensuring a sustainable future for urban transport.

An SBL Automotive spokesperson said: “Delighted to announce our bi-fuel evolution of the LEVC TX is now available for TXs licensed by Birmingham City Council.

“Adopting LPG or biopropane in place of petrol lowers net CO2 emissions by 10% (using LPG) or 99% (using biopropane) and lowers operating costs by 20%+.”

CNG Fuels are pleased to announce that we have now completed the development and commissioning of our latest Bio-CNG Refuelling Station in Newton Aycliffe. The station is now fully operational and open to all current and future customers.

The address for the new site is:

CNG Fuels. Newton Aycliffe, Newton Park,

Coatham Mundeville, Darlington, DL1 3NL

The station is located directly off Junction 59 of the A1(M). This station will serve both local businesses with large HGV fleets and passing fleets using the A1(M) and will introduce fleets from Newcastle, Sunderland, Middlesbrough, and Darlington to Bio-CNG as a transport fuel for HGVs.

The station at Newton Aycliffe comprises 14 refuelling dispensers, allowing more than 60 trucks to be refuelled per hour with a total capacity of more than 27 million kilograms (kg) of Bio-CNG annually, making it CNG Fuels’ highest capacity station to date.

Bio-CNG is considered the lowest carbon and most cost-effective alternative HGV fuel to diesel, reducing emissions currently by 90% vs Diesel, whilst also providing 30-40% lifetime fuel cost savings.

This is now CNG Fuel's 11th large-scale public access Bio-CNG Refuelling station to become operational, the other locations include; Warrington, Avonmouth, Bellshill (Scotland), Leyland, Erdington (Birmingham), Northampton, Crewe, Newark, Knowsley (Liverpool) and Castleford.

CNG Fuels are currently in build with two other Bio-CNG stations, located in Corby & Bangor (North Wales) and expect to have these operational over the next few months. There are many more other locations in our development pipeline, with some of them due to go into construction imminently.
