Port Talbot-based R-Tech Materials (
www.r-techmaterials.com) has won an award for its work on a safety sensor for hydrogen fuel cell storage tanks in cars.
Working with TWI, Pancom and Arcola Energy, the company used its testing expertise to develop an early-warning system to alert drivers to any damage to the cell while in service.
R-Tech director Tony Franks said: “We are delighted to have won this award, which recognises our expertise in both testing and R&D.
Hydrogen is a very clean fuel, and it enables vehicles to run for long distances, but the public perceive it to be incredibly dangerous, thanks to the Hindenburg disaster in 1937.
"Our early-warning sensor system aims to redress the balance by reassuring drivers that hydrogen fuel cell vehicles can be safe as well as clean.”
Using sensors and expertise provided by Pancom, R-TECH conducted a number of different static and dynamic mechanical tests in order to produce a characteristic acoustic-emissions ‘mother curve’ for the hydrogen fuel storage cylinder typically used in cars.
The failure modes and locations detected by acoustic emissions were then confirmed by X-Ray CT at TWI in Port Talbot.
A prototype of the early-warning system has now been produced; it is currently undergoing field trials.
