Riversimple is a United Kingdom-based car manufacturer of hydrogen-powered fuel cell electric vehicles (FCEVs). It is based in Llandrindod Wells, a town in Wales, where there is a research & development centre and the company's offices. Riversimple was founded by former motorsport engineer and racing driver Hugo Spowers. [1]
Riversimple was founded by former motorsport engineer Hugo Spowers in 2001; it became Riversimple in 2007. Until 2014 the head office was in Ludlow, England. The offices were located at Dinham, by the River Teme, which gave the business its name. Riversimple has a diverse team which includes those with F1, motor racing, yacht design, engineering and automotive design backgrounds. Riversimple has now relocated to Llandrindod Wells where it intends to build its first mass production facility.
Riversimple has developed three projects.
The LIFECar was designed to be an R&D project. Part-funded by the Technology Programme (now Innovate UK), this model ran in a test cell which proved beyond doubt that the technical proposition was viable. [2]
The Hyrban was a lab demonstrator designed to prove that a 6kW powertrain could produce the performance required for urban use and demonstrate the Network Electric Platform in a running vehicle. It was capable of 0-50mph in 8 secs and 50mph cruise. [3]
The Rasa is a further development of the Riversimple vehicle. This model is robust as well as efficient and has been designed for regulations, safety, practicality and ease of use rather than as a powertrain demo. It is designed for EC Whole Vehicle Type Approval (ECWVTA) and using methodical design processes and standards (ISO26262). The engineering prototype was on the roads in January 2016. [4] [5]
Refinements to the engineering prototype have been incorporated into every aspect of the new cars now in production in the new Riversimple workshop in Llandrindod Wells. Safety-critical software, component packaging, air intake and energy management systems are all new. [6]
The company produces their vehicles on a 'sale of service' model, under which users have use of a Riversimple vehicle for a monthly fee, which covers road tax, insurance, fuel and maintenance costs.[ citation needed ]
Riversimple state that they sell 'mobility as a service, not cars as a product' and that this approach incentivises them to make cars that last longer, use less resource and to maximise recovery at the end of the vehicle’s life.
Though the UK hydrogen refuelling infrastructure is in its infancy (with 13 UK refuelling stations as of February 2020) Riversimple’s model sees the company initially supplying their vehicles in the vicinity of hydrogen refuelling facilities. As of December 2018, several public and private sector organisations were signed up and over 3,000 individuals had expressed an interest in being customers.[ citation needed ]
The Riversimple company designs energy-efficient automobiles, including the Morgan LIFEcar and the Riversimple Urban Car. [7] Several elements are considered during each design, including hydrogen fuel cell power sources, lightweight carbon fibre composite materials, open-source development and design, leasing instead of selling the cars, distributing manufacturing among many small manufacturing plants, and broad corporate ownership. [8]
Riversimple unveiled its working 'alpha' prototype, the two-seat Rasa (the name is derived from Tabula Rasa, which means 'clean slate' in Latin) on 17 February 2016. [9] This was the culmination of 15 years of development of the concepts developed and espoused by Riversimple founder, Hugo Spowers, whose first FCEV design was the LIFECar, a research project developed by a consortium with Morgan, followed by a tech demonstrator urban vehicle.(Their first version was known as the Riversimple Urban Car).
The company’s 'beta' prototype, features several improvements over its predecessor, to drivetrain, wheels, interior equipment, headlights and aerodynamics. The 'beta' prototype also utilises a fully carbon fibre monocoque chassis.
The Rasa was designed by car designer Chris Reitz, [10] who styled the new Fiat 500. The Rasa has a range of 300 miles on 1.5 kg of hydrogen, and achieves the equivalent of 250mpg with a top speed of 60 mph. Emissions are zero at tailpipe (just water vapour) and c.40gCO2/km Well-to-Wheel. Hydrogen refuelling for the Rasa takes three minutes.
The Rasa is powered by an 8.5 kW hydrogen fuel cell, and a regenerative braking system, which recovers up to 50% of the braking energy. The vehicle also uses a 1.9MJ lithium-ion hybrid capacitor set, providing additional power for acceleration. Electric motors in each wheel produce a combined 16 kW continuous power and 55 kW peak power.[7]
The Rasa is an open source vehicle. Riversimple cites the reason for this as wanting to work towards common goal of reducing environmental damage. [11]
A€2m European FCHJU SWARM grant was utilised to support the development and build of 20 Riversimple Rasas, to install and commission a hydrogen fuelling station and to support the rollout of a 'clean mobility trial', in and around Abergavenny, in mid-Wales. A further £1.25m grant from the Office for Low Emission Vehicles' Hydrogen for Transport Programme, was awarded in February 2019. [12] The trial (in partnership with Monmouthshire County Council) will see over 200 testers, drawn from households, car clubs and businesses. It is estimated that each vehicle will generate on average 20Gb of data per day, during the trial.
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel and an oxidizing agent into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied.
A hydrogen vehicle is a vehicle that uses hydrogen fuel for motive power. Hydrogen vehicles include hydrogen-fueled space rockets, as well as ships and aircraft. Power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by burning hydrogen in an internal combustion engine.
fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen. Most fuel cell vehicles are classified as zero-emissions vehicles that emit only water and heat. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas. Transporting and storing hydrogen may also create pollutants.
A hydrogen station is a storage or filling station for hydrogen. The hydrogen is dispensed by weight. There are two filling pressures in common use. H70 or 700 bar, and the older standard H35 or 350 bar.
The Honda EV Plus was the first battery electric vehicle from a major automaker that did not use lead acid batteries. Roughly 340 EV Plus models were produced and released. Production of the EV Plus was discontinued in 1999 after Honda announced the release of its first hybrid electric vehicle, the Honda Insight.
The Morgan LIFEcar was originally a fuel cell-powered electric vehicle project undertaken by Morgan Motor Company and startup company Riversimple. The goal of LIFEcar was a sports car that would be environmentally responsible, and deliver impressive performance. Research and development was backed by QinetiQ, a British defence technology firm, as well as several universities, including Cranfield University and the University of Oxford, and government grants. The project abandoned the fuel-cell architecture in favour of a hybrid approach with a 15-mile electric range.
Hydrogen technologies are technologies that relate to the production and use of hydrogen as a part hydrogen economy. Hydrogen technologies are applicable for many uses.
A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power a propeller. Unlike most aircraft, which store fuel in the wings, hydrogen-powered aircraft are usually designed with the hydrogen fuel tanks inside the fuselage.
The Toyota FCHV is a current hybrid hydrogen fuel cell vehicle development programme of the Toyota Motor Corporation, which was leased to a limited number of drivers in the United States and Japan beginning in 2002. "FCHV" stands for "Fuel Cell Hybrid Vehicle". A number of prototypes have been produced, up to the latest FCHV-adv ("advanced").
Eco-Runner Team Delft is a Delft University of Technology student team, aiming to promote a sustainable future by building the world's most efficient hydrogen-powered car. At the end of the year, the team participates in the Shell Eco-marathon competition in order to assess the efficiency of the vehicle. Eco-Runner Team Delft won the competition in 2015 and 2022. In the competition there are two vehicle classes: Prototype and UrbanConcept. For years Eco-Runner Team Delft participated in the Shell Eco-marathon Prototype class competition where the goal is to cover a certain distance with the least amount of hydrogen. In the year 2019–2020, the team has decided to compete in a different competition; the Urban Concept class. This challenge offers the team the opportunity to design and build an efficient hydrogen-powered vehicle that is closer in appearance to modern city cars.
The Honda FCX is a family of hydrogen fuel cell automobiles manufactured by Honda.

The Mazda Premacy Hydrogen RE Hybrid or Mazda5 Hydrogen RE Hybrid was a hydrogen powered hybrid car produced by Mazda. Later models were also called the Mazda Hydrogen RE Plug in Hybrid. The first car was unveiled in 2005, with an improved version shown at the 2007 Tokyo Motor Show. Mazda planned for the car to enter production and leased a few cars to end users in 2009 in 2010.
The Riversimple Urban Car is a conceptual open source hydrogen fuel cell vehicle that was proposed by Hugo Spowers' company, Riversimple, in 2009. Their latest model, the Rasa, was unveiled on 17 February 2016.
The Toyota Mirai is a mid-size hydrogen fuel cell vehicle (FCV) manufactured by Toyota, and is one of the first FCV automobiles to be mass-produced and sold commercially. The Mirai was unveiled at the November 2014 Los Angeles Auto Show. As of December 2021, global sales totaled 17,940 units; the top-selling markets were the U.S. with 9,274 units, Japan with 6,618 and the rest of the world with 2,048.
The Hyundai ix35 FCEV or Tucson FCEV is a hydrogen fuel cell electric vehicle developed by Hyundai. The model is a left-hand drive only conversion to the SUV platform it is based on and was the first of its type to be mass-produced and sold commercially in the world. Different versions are known, the previous version was based on the Hyundai Tucson FCEV, and the upcoming model is based on the current ix35 FCEV. The first generation was introduced in 2001, with the Hyundai Santa Fe FCEV, and had a range of 100 miles (160 km), with a top speed of 78 mph (126 km/h).
The Hyundai Nexo is a hydrogen fuel cell powered crossover SUV that was revealed at the 2018 Consumer Electronics Show on January 8, 2018. Replacing the Hyundai Tucson FCEV, the Nexo is the flagship for Hyundai's "eco car" portfolio.
There are numerous versions of vehicle propulsion systems. Many of those came into fruition due to need for cleaner vehicles. Each of them might have many abbreviations and some might be misleading. This article explains shortly what defines them.
The British Rail Class 799 are tri-mode multiple units prototype adapted from Class 319 electric multiple units (319001/382). The existing 25 kV AC and 750 V DC equipment has been retained with a hydrogen fuel cell added, currently taking up one of the carriages.
