ETI, Loughborough University, Johnson Matthey & Caterpillar launch £4.5M project to improve effectiveness of SCR aftertreatment systems for heavy-duty vehicles
The UK public-private partnership Energy Technologies Institute (ETI), Loughborough University, Johnson Matthey and Caterpillar have launched a new £4.5-million (US$7.2-million) technology project to improve the effectiveness of Selective Catalytic Reaction (SCR) aftertreatment systems for NOx reduction in heavy duty vehicles (HDVs).
The project aims to help HDV fuel efficiency by developing a more efficient exhaust aftertreatment system. Often diesel engine fuel efficiency is reduced by having to comply with exhaust emission standards. It is hoped that the new exhaust system developed by this project will effectively remove this constraint. The project aims to deliver fuel efficiency and CO2 benefits of between 3%-4%.
The ETI commissioned and funded project will be led by Johnson Matthey, which in addition to collaborating with the university, will also work alongside ETI member Caterpillar. The work by the university will be carried out by the School of Mechanical and Manufacturing Engineering.
Within the project, the University’s research team will develop some unique optical test facilities for the analysis of HDV exhaust after-treatment systems, with the aim of developing world-leading exhaust emission standards reduction technology.—Loughborough University Professor Graham Hargrave
The project will mark the first collaboration between Loughborough University—which is part of the project consortium—and the ETI. The ETI, which is based at Holywell Park in Loughborough, is hosted by the universities of Loughborough, Birmingham and Nottingham as part of the Midlands Energy Consortium.
The ETI is a public-private partnership focused on the acceleration of the development of affordable, secure and sustainable technologies that will help the UK meet its long term emission reductions targets. ETI industry members include BP, Caterpillar, EDF, E.ON, Rolls Royce and Shell.
Energy efficiency is a big challenge facing the UK. Our modeling work points to efficiency in transport and in the HDV sector as an area that can make a meaningful difference in helping to reduce carbon emissions. However, we have to achieve our CO2 goals whilst meeting the cost, reliability, space and exhaust emission standards constraints that exist within the HDV market. To help industry embrace new exhaust systems designs we need to ensure that the efficiencies created come with an affordable price tag—so our work with Loughborough University, Johnson Matthey and Caterpillar will be focused on delivering an economically viable solution.—Chris Thorne, Program Manager, HDV Efficiency at the ETI
This project is part of a £40-million (US$64 million) ETI program focused on increasing HDV efficiencies. Officially launched last year, the program aims to improve systems integration and technology development across the HDV sector (including trucks, buses, agricultural machines, construction equipment, quarry and mining machines, and marine transportation)—with an aim to increase the efficiency of land and marine vehicles by up to 30%.
