Plymouth Citybus and Plymouth City Council are trialling technology known as an EXO
cell developed by Atmos-Clear Limited (www.atmos-clear.com) on 5 vehicles each, with the aim of reducing the production of toxic emissions from engines.
Installing at Plymouth Citybus depot on the 1st of 5 vehicles.
Case Study Description
The system works by adding hydrolysed gas to the regular fuel/air mixture. The result is a faster, cooler fuel burn which eliminates almost all waste gases produced and provides overall better fuel economy
Different cell sizes can be used for various vehicles, all the way from car derived vehicles and those with small engines to larger commercial vehicles with larger engines
Trials have previously taken place in locations such as Paris and are now taking place in Plymouth
How this has helped the South West of England
This trial shows how Plymouth is at the forefront of the development of these new technologies to help Plymouth and the wider region to develop a route to net-zero
Technologies that can help reduce emissions of diesel and petrol vehicles can offer a quicker solution in comparison to alternatively fuelled vehicles which may be more expensive and take longer to come through
This also offers a versatile solution that can help a number of vehicle types with different engine sizes, offering a possible solution to a wide variety of vehicles within the freight sector

Note: This case study has been developed as part of the South West Freight Strategy for Peninsula Transport and Western Gateway Sub-National Transport Bodies by AECOM and WSP transport consultancies.
