Vehicle Development

We have expanded our technical team and continue to develop both our vehicles and our business model. We have recorded over 20,000 miles of real-world testing and have successfully deployed remote fault detection and correction through telematics. Ongoing powertrain development has been focused on:

– Energy management software

– Suspension set up and vehicle dynamics

– Hydrogen delivery system

– Fuel cell system integration and temperature control

– Traction motor development

– Cabin heating and ventilation

Successful Public Trials

Built for testing with the public before we finalise designs for mass production, Rasas have been driven for thousands of miles across the UK, with lessons and feedback rigorously collected. Members of the general public first took the wheel in April 2021 in Monmouthshire. Rasas were also an integral part of the Milford Haven Energy Kingdom (MH:EK) project in Pembrokeshire, demonstrating the viability of hydrogen vehicles and the Riversimple service model in 2022. They have been in the hands of trialists in Monmouthshire since then.

Riversimple’s mission to drive down emissions

According to the International Energy Agency (IEA) transport emissions account for 24% of global air pollution, and as such, have a significant impact on the quality of the air we breathe. With more stringent regulations and advancements in automotive technology, we are seeing a decrease in exhaust pollutants from vehicles. However there is also a
