Powering Fire Service vehicles with sustainable fuel

After successful trials using Hydrotreated Vegetable Oil (HVO) in workshop vehicles, Avon Fire and Rescue Service are taking the next step to implement the use of this more sustainable fuel as they strive to reduce the environmental impact of their vehicles. In an exciting collaboration between Fleet and Tech Services, the Environment Team and crews at Avonmouth Fire Station, the first operational trials of this more environmentally friendly fuel will start in February 2026.  

HVO is a renewable diesel substitute producing up to 90% less emissions than traditional diesel. It also releases less tail pipe particulates, has a longer shelf life than diesel, and its production is less environmentally detrimental than fossil fuels. Known as a ‘drop in fuel’ it can be substituted in suitable vehicles with no modifications required and with no impact on performance. This was tested through robust trials by Fleet and Tech Services through 2024-25 to ensure that wider use of the fuel would not impact operations.  

“In an era where environmental concerns and operational efficiency are at the forefront of everyone’s mind, emissions reductions have become a critical focus for us as an emergency service to assist in our sustainability targets. I’m pleased to be starting this phase of the trial, as we’re keen to trial new methods to reduce our carbon footprint as a Service. We’re looking forward to progressing with the use of HVO and other renewable energy sources”.

Matt Derrick, Head of Fleet and Technical Services. 

This Spring crews at Avonmouth station will be part of the next stage of this innovative trial with one vehicle being allocated to run solely on HVO from February. A fuel bowser will be placed onsite, maintained and monitored by Fleet support staff, allowing practical access to the station crews. The initial trial will run for 3 months with feedback from Firefighters informing the next steps of HVO use across the service.   

 “I am pleased to support the trial of HVO fuel at Avonmouth as it offers a practical, low-risk way to reduce lifecycle carbon emissions while maintaining the same performance and reliability as conventional diesel. This trial would provide valuable data to inform future rollout decisions and demonstrate our commitment to more sustainable fuel options without disrupting day-to-day operations”. 

Andy Lewis, Station Manager, Avonmouth Fire Station. 

Vehicle fuel accounts for around 60% of the Service’s carbon emissions and, as suitable low emission operational vehicles are not yet a feasible option, using HVO as an environmentally friendly alternative will play a vital role in reducing the service’s carbon footprint and environmental impact, without compromising operational performance.  

“We are very pleased that this trial is progressing and that the crews at Avonmouth Station have volunteered to lead the way. This collaboration demonstrates the ongoing commitment of AFRS to reduce the environmental impact of activities, explore new ideas and innovations, and work in partnership across the Service.”
