Modified John Deere makes tracks as world’s first ammonia-fueled tractor

Interest is rising in different gas sources for tractors that assist sidestep heavy diesel air pollution, and given its widespread use as agricultural fertilizer, ammonia would possibly simply be a main candidate. Brooklyn-based startup Amogy has damaged vital new floor on this space, becoming its zero-emissions vitality system to a John Deere tractor to make the primary ever tracks as an ammonia-powered heavy responsibility car.

We’ve seen plenty of attention-grabbing car ideas aimed toward chopping into the air pollution created by tractors. This consists of plenty of electrical choices, a few of which declare to be the smartest tractors within the room, and even ones powered by methane claimed to emit 80 p.c much less CO2.

Ammonia as a gas supply has began to indicate promise throughout just a few modes of transportation, together with delivery and aviation. Important questions stay over the simplest means to attract vitality from ammonia, and the way we will clear up the energy-intensive processes concerned in its manufacturing, however Amogy believes its know-how is poised to faucet into its huge potential.

Its vitality system consists of a tank to retailer ammonia in liquid kind, which is fed into “highly-efficient” cracking modules that break up it into nitrogen and hydrogen. The ensuing hydrogen is what runs the system’s gas cell, which Amogy says can present ongoing energy for a number of hours at a time. The firm says its resolution provides 5 occasions the system-level vitality density of a lithium-ion battery, at greater than 700 Wh/kg.

This vitality system was built-in into an otherwise-standard John Deere tractor with the power to hold out common farming duties, however with out the same old emissions. Amogy says the tractor was taken on a number of excursions with refueling in between, which it notes is as quick and easy as gasoline refueling of a traditional car.

“We’re thrilled to be demonstrating our zero-emission ammonia power solution in action in a tractor for the first time ever,” said Amogy CEO Seonghoon Woo. “Ammonia is a viable zero-emission fuel for all heavy-duty vehicles, but especially farming and agriculture, where the readily available chemical has been used as a fertilizer for decades.”

The firm says technological enhancements over the previous yr have seen a 20-fold improve within the energy capability of its ammonia-based vitality system. It sees this tractor demonstration as an vital first step in its efforts to decarbonize different heavy-duty transportation resembling trucking and delivery, with additional demonstrations deliberate within the coming yr.

“As we proceed our work to steer improvements in ammonia-based gas options, the Amogy group believes this demonstration and future ones, together with Class 8 vehicles and delivery vessels to be demonstrated within the subsequent 12 months, will speed up the adoption of ammonia as the following era gas to exchange polluting diesel engines with an emission-free resolution amongst transportation business sectors and funding companions,” mentioned Woo.
