In a groundbreaking trial at the Very Light Rail National Innovation Centre in the West Midlands, Advanced Hydrogen Technologies (AHT) Group successfully demonstrated the effectiveness of their Engine Carbon Clean and Capture device on a Class 08 locomotive. Collaborating with the Harry Needle Railroad Company (HNRC), the trial revealed impressive results, including a 22% reduction in exhaust gas emissions, a 20% decrease in heavy particulates, and an 8% improvement in diesel efficiency. AHT's innovative technology, featuring a four-cell hydrogen generator, efficiently removed carbon build-up in diesel engines, followed by a bespoke capture device that further reduced harmful emissions and particulates, showcasing the technology's efficacy. Positive feedback from industry professionals and AHT's CEO underscores the device's potential to help businesses reduce their carbon footprint, lower fuel costs, and align with net zero goals. The trial also highlighted substantial decreases in various emissions, such as carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, and formaldehyde, with a specific focus on targeting particulate matter known for its adverse health effects. Notably, the non-invasive application of the technology ensures no damage to engine components, making it suitable for a wide range of locomotives without requiring parts removal or harsh chemical treatments. AHT plans to expand the deployment of their system, aiming for mainline certification in the future to further validate its economic and environmental benefits. This trial marks a significant milestone in railway technology innovation, offering practical solutions that enhance operational efficiency and promote environmental stewardship in the industry.
