Howard Tenens rolls out dual fuel HGVs across its fleetHoward Tenens vehicle


Howard Tenens is leading the logistics industry in low carbon transport with the rollout of dual fuel (gas/diesel) vehicles across its HGV fleet. The rollout follows a successful trial period and this low carbon strategy is now supported with the installation of refueling stations – one of which is already in situ at Howard Tenens, Andover with a further two stations planned for 2011.

Case study

Howard Tenens has introduced dual fuel vehicles to its fleet of HGVs as part of its sustainable development plan. Howard Tenens takes its corporate, social and environmental responsibility seriously and has made a commitment to reduce the carbon footprint of storing and transporting its customers’ products.

Following discussions with Mercedes-Benz UK, Howard Tenens engaged in a two vehicle trial. The vehicles were fitted with Hardstaff Dual Fuel OIGI technology using the umbilical trailer system and Compressed Natural Gas cylinders for fuel containment.

As part of the Group’s sustainable development plan, research was carried out into all available road transport fuels (biodiesel, hybrid, hydrogen, fuel cell etc) and determined that natural gas was the only readily available low carbon alternative suitable for HGVs.

Truck manufacturers have made significant changes in technology to meet Euro standards. Howard Tenens has taken a further step towards improved environmental performance by investing in dual fuel conversions and going beyond existing good practice.

During the trial Howard Tenens went through a 6 month development process with the manufacturer to allow optimisation of the technology.

In the not too distant future the natural gas will be replaced with biomethane a renewable version of natural gas.

The trial resulted in a further 12 dual fuel vehicles being ordered and Howard Tenens has a roll out plan for vehicles across the fleet. Howard Tenens has had much interest from other transport companies and expect many to follow its lead.

While running the two trial vehicles, Howard Tenens saved 36,036 kg of CO2. Since the trial the Group has increased the number of dual fuel vehicles to 14.

Howard Tenens expects to replace 518,966 litres of diesel with an equivalent energy value of natural gas which has lower carbon content. This will potentially achieve a saving of 302,700kg of CO2 per annum.

Once rolled out across the group, it anticipates over 1 million kg saving per annum.

In support of its low carbon transport strategy, Howard Tenens has invested in a refueling station at its Andover depot in April 2010 with a further two installations planned for 2011 at its London and Boston depots. Howard Tenens believes that it is sharing best practice by permitting third party access by arrangement so that others can operate gas vehicles without the incurring the capital outlay.
