Electric tractors may be coming to UK farms at least 10 years sooner than anticipated, according to the NFU.
A NFU paper, Electric tractors by 2020? – a review of advanced vehicle technology in the agricultural sector (PDF), describes the possible technology options of electric tractors.
The research was published as John Deere unveiled its Sustainable Energy Supply for Agricultural Machinery tractor at the SIMA farm machinery show in Paris this week.
The Deere tractor, based on the company’s 6R Series tractor chassis, incorporates a 130-150kW-hour battery, which can deliver 174hp of continuous power and run for four hours on a three-hour battery charge.
The NFU anticipates that diesel-electric hybrid and battery-electric tractors will be widely available from 2020 onwards.
The paper says biobased low-carbon fuelling of agricultural vehicles “may remain more of a niche opportunity”.
However, autonomous aerial and ground vehicles are expected to make “a growing contribution to farm management”.
Jonathan Scurlock, NFU renewables expert, said: “Imagine a farm where electric agricultural vehicles, some autonomous, some conventional, are connected to charging points in large solar PV equipped ‘carport-style’ machinery sheds, earning additional income from so-called ‘vehice-to-grid’ network balancing services while they are on charge.
“This may no longer be science fiction, but instead the technology of the near future.”
The benefits of electric tractors over diesel-powered tractors include reduced running costs, fewer emissions and possibly less maintenance, as well as the considerable safety aspects of switching from mechanical pto to electrical interfaces.
