But that isn't the only reason it's more efficient, as the company says the fuel can easily be produced by methane from cow pies, allowing for a more circular economic model in the most circular of industries.

The pioneering 270hp tractor is claimed to be a match for the performance of standard diesel-powered versions. The groundbreaking machine was developed by British company Bennamann, which has been researching and developing biomethane production for over a decade.

Waste byproducts from a herd as small as 100 cows are turned into a fuel called fugitive methane in a biomethane storage unit based on the farm.

A cryogenic tank fitted on the tractor keeps the methane in liquid form at -162 degrees°C giving the vehicle as much power as a diesel but with significant emission savings.
