Tarmac Innovation Challenge winner revealed

Hydrogen fuel supplement system

Hydrogen fuel introduction system to be brought to life as winner of Tarmac’s 2022 Innovation Challenge

AN innovative hydrogen fuel supplement system has been named as the winner of Tarmac’s 2022 Supplier Innovation Challenge, an initiative that encourages suppliers, organizations and individuals to submit ideas which can support the acceleration of the company’s journey to net zero.

With entries scored against criteria including technology readiness, potential business impact, and feasibility, the winning and highly commendable entries are refined, developed, and brought to life by Tarmac as part of the scheme.

This year’s winning entry was submitted by Prior Power Solutions for a hydrogen introduction system that can be fitted on to new or existing diesel engines to supplement cleaner hydrogen fuel into internal combustion engines (ICEs), offering CO2 reductions of 8%.


Rather than storing hydrogen in the vehicle, it is produced on demand from de-ionized water. This is then pumped into the engine so that less diesel-based fuels are required, resulting in an 80% reduction in diesel particulates and more than a 20% reduction in nitrogen oxides.

The reduced diesel content also means that engines remain cleaner and, therefore, require less maintenance over time, increasing the lifespan of vehicles with this innovative system implemented.

In addition to the reduction in polluting emissions, the fuel efficiency and torque of vehicles can be increased, leading to ongoing cost savings for vehicle operators.

Jonathan Harry, procurement director at Tarmac, said: ‘At Tarmac, there is a business-wide focus on sustainable innovation and solutions which help customers and clients deliver better outcomes for both the built environment and wider society. It’s important to remember that we are not alone in this ambition and that collaboration with our suppliers is key to meeting sustainable targets.

‘A huge congratulations to Prior Power Solutions for putting forward this innovative technology which can help transform ICE vehicles into more-sustainable, longer-lasting assets. Working in collaboration, we are excited to see the start of the next phase of development.’

James Rix, managing director of Prior Power Solutions, commented: ‘We are delighted by this award, which builds on growing interest and demand for more sustainable power solutions that are available now for existing assets.

‘We believe this hydrogen introduction system will contribute to a lower-carbon economy and we are excited by this award and partnership with Tarmac in bringing this technology to industry.’

Last year’s Innovation Challenge successes include a 100% recyclable, net-zero-carbon cement bag and the UK’s first e-mixer in partnership with Renault Trucks, which is shortly due to be delivered to Tarmac’s Birmingham asphalt plant.
