The NH3 Car – an alternative way to power our future

A prototype vehicle powered by an ammonia fuel engine (AFE) is being built by a research team from Ohio University’s Russ College of Engineering and Technology. 
The fuel-cell electric vehicle requires no hydrogen storage – it is generated on board via an ammonia electrochemical reformer.


Stage 1 of the project (led by Grad student Christopher Gregg) involves the development of The Ohio University “Alternative Energy Testbed Electric Vehicle”

Why an ammonia car? Where will the ammonia come from? Does it lessen our reliance on petroleum?  Can we make enough to cover a big part of our transportation fuel needs?

An ammonia car has potentially high energy efficiency and could use ammonia from waste sources, so it is an important part of the future transportation picture.


When will the prototype be finished?

Projected completion of phase 1 by June 2007


What is its fuel economy?  What is its range?

60 mpg_ge (based on 90 mpg for a hydrogen-based fuel cell car)


What is the advantage over other on board reformers that produce hydrogen?


Is it safe? Is the fuel dangerous? What happens in a wreck?


What would a fuel station look like?


What are the biggest technical challenges to overcome before this technology

could be on the market?
