Abstract
The latest London Atmospheric Emissions Inventory published by the Greater London Authority, indicated that Non-Road Mobile Machinery is a significant source of air pollution. This poses health risks and contributes to poor local air quality.
To reduce emissions linked to construction activities, HS2 has set stringent engine emission standards for all plant and machinery across the programme. As part of the HS2 innovation programme, a retrofit solution was developed and was the first certified solution. This adds exhaust technology to existing engine systems on plant machinery to upgrade them to meet the latest engine emission class, reducing pollution and leading to cleaner air around construction sites.
The retrofit solution was fitted and trialled on a piling rig and rotary rig. The solution was tested to quantify the emission saving potential of the system.
The results were validated and certified making the solution available industry wide. By reducing emissions and embodied carbon, benefits are realised for the environment, communities, and workforce. In addition, bringing significant direct capital savings of up to £300million on the HS2 programme through the reduction of plant scrappage and the need to purchase high volumes of new large specialist plant.
