Based in mid-Wales, Riversimple released their first prototype, Rasa, in 2016 – a new prototype hydrogen fuelled cell car. The car can reach top speeds of 60mph in 10 seconds, with the entire car weighing just 580kg. After 15 years of design and development, the Rasa uses clever engineering to redirect wasted energy around the car, reducing its energy consumption and boosting acceleration.


For the environmentally conscious, the Rasa prototype takes just 3 minutes to fill with renewable hydrogen and can last up to 300 miles. The fuel is covered in the monthly rental fee for customers, as well as the maintenance and depreciation. It’s CO2 emissions are significantly less than even an electric car, making the Rasa a contender for the most sustainable car in the world.


In 2017, the UK announced by 2040 it would ban the sale of new petrol and diesel cars. In response, leading automobile companies are estimated to invest $10 billion over the next 10 years in developing hydrogen technologies.


Riversimple received £2.1 million in grant-funding in 2015 by the Welsh Government, and €2m from an EU grant for beta testing. Most recently, Riversimple closed a £1m crowdfunding campaign, attracting big global investors. This money is being used towards the build of 20 Beta cars for a 12 month trial with the general public. Over 900 people applied to be part of the testing, showing an appetite for sustainable personal motors.
