Engineering tech firm Advanced Hydrogen Technologies (AHT) Group said an independent trial of its carbon capture device on HGVs found particulate number counts plummeted by more than 90%.

The 18-month trial studied the microscopic particles emitted by control diesel trucks compared to identical vehicles operated by Abels Moving Services fitted with the capturing technology.

It said the control HGVs averaged a particulate number count of 116,300cm³ while those fitted with the AHT carbon capture device peaked at 10,030cm³ - a reduction of 91.4 % and more than 10 times less.

AHT’s testing process uses hydrogen to remove carbon build up, which is worst in diesel and high mileage engines.

The UK Government and similar organisations focus on gases as part of the Euro Emissions Standard initiative, but AHT said its system further reduces harmful fine particulates, less than 2.5 micron in diameter, which are strongly associated with detrimental health effects.

Mark Costa-Rising, CCO at Abels Moving Services’ parent company, AGM Group: said: “We’re delighted with the results and utilising this technology on our vehicles going forward will give us real partnership leverage when it comes to proving ESG compliance and reduction of our carbon output.”

AHT Group’s CEO, Ben Kattenhorn, said: “These results clearly demonstrate how our award-winning proprietary technology harnesses the power of hydrogen to drastically reduce vehicle emissions and over the coming months we will be revealing further evidence following independent trials with other household names.

“We envisage the widespread use of hydrogen as the primary source of safe, economical and sustainable energy, with the potential to reduce not only pollution but also household energy bills: it’s the future of cleantech.”
