Company Overview

Riversimple is developing breakthrough hydrogen electric vehicles that could transform the automotive landscape. The company is prioritising lightweight vehicle architecture to maximise energy efficiency and a unique business model designed to make sustainability profitable.  Our modular hydrogen fuel cell drivetrain platform is designed to be adapted for use in multiple vehicles classes, from a 5 seater family car to commercial vans, for consumer and commercial markets with global potential. We have a growing waiting list of both individuals and organisations.

Riversimple has been funded to date through a combination of equity investment from family offices, crowdfunding and grants. The British Business Bank is a minor shareholder in Riversimple, as is the Development Bank of Wales.

We will shortly be launching a crowdfunding campaign as we prepare for scaling up and we are working with Gambit Corporate Finance LLP on scale up funding for volume manufacturing.

Vehicle Development

We have expanded our technical team andcontinue to develop both our vehicles and our business model. We have recorded over 16,000 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 have also been 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.
