  • The 270bhp tractor runs on fuel captured from cow dung.
  • Cow dung is treated, compressed, and turned into low-emission fuel using a processing unit.
  • The tractor can reduce carbon dioxide emissions from 2,500 to 500 tonnes a year.
Cow waste or cow dung has been traditionally used as a crop fertilizer for decades because of its organic content. But now, a British company has created a ‘New Holland T7’ tractor that runs on cow dung. This tractor could be a game changer in the green energy-striving agriculture industry.

Agricultural company CNHA Industrial partnered with Bennamann, a company that specializes in methane energy products, to create this green-energy tractor. The New Holland T7 tractor boasts 270 horsepower and runs on fuel captured from farmyard manure. The tractor is said to match the performance of standard diesel-powered versions.

How does it work?

It works by collecting waste by-products from cows into a biomethane storage unit. The cow waste product releases a gas known as fugitive methane that is then treated, compressed, and turned into the low emission fuel using a processing unit.

The cryogenic tank fitted on the tractor keeps the methane in liquid form at -162 degrees giving the tractor significant power and emission savings. Furthermore, methane can be transported similarly to diesel using the cryogenic storage tank.

The machine is developed by the Cornish company Bennamann, which has been researching and developing biomethane products for decades.

The tractor was put in a pilot run on a farm in Cornwall where carbon dioxide emissions were slashed from 2,500 tonnes to 500 tonnes in just a year.

Bennamann co-founder Chris Mann said, “The T7 liquid methane-fuelled tractor is a genuine world-first and another step towards decarbonising the global agricultural industry and realizing a circular economy.”

This new fuel technology will be scalable and affordable energy option for farmers. It will also provide new opportunities and revenue models to monetize cattle by-waste products. Other than this, it will open doors for using 100% natural fertilizers and converting excess methane into electricity that can be used to power farms in remote and rural areas.
