What’s special about a Hydrogen Fuel Cell?

At Riversimple we think of hydrogen as an energy carrier not a fuel.

Petrol and diesel are primary fuels – you can dig them out of the ground – but if you think of hydrogen as a fuel you can make the wrong choices. In the past, some car companies invested a lot of time and money designing cars that burned hydrogen. Due to the quantity of gas required, the engineers also experimented with super-cooled liquid hydrogen, but there were numerous problems and the designs were dropped at a fairly early stage, mostly without reaching the market.

Riversimple at the National Exhibition Centre

At the beginning of November, Team Riversimple were to be found at the National Exhibition Centre in Birmingham.

The annual Advanced Engineering Show has acquired an international reputation, attracting and demonstrating the latest developments in engineering. We had Riversimple’s Alpha Mk2 rolling chassis (the entire Hydrogen car minus external body shell) on show and it certainly attracted plenty of interest.

 

 

At present the design of the body shell is being kept under wraps, but from the point of view of the engineer it is the nuts and bolts of the interior that really fascinate.car-2

This is the culmination of fifteen years development at Riversimple. Designing around hydrogen fuel cell technology has allowed us to re-invent the car for the modern world. We have four electric motors, one in each wheel and these motors are also the brakes – recovering over 50% of kinetic energy when braking. There are super-capacitors to store this energy and the recovered energy is fed back into the system to provide 80% of the power for acceleration. The primary power source is a relatively low powered hydrogen fuel cell ( 8.5 kW) housed in a beautifully constructed framework of lightweight composites.

Our overall design gives us a groundbreaking efficiency and range, many times better than inserting fuel cells into conventional, heavy, vehicles. This also means it will be agile and fun to drive, and with a massive feel good factor, as we strive towards zero cost for the environment.

THIS IS WHAT IS POSSIBLE – Mobility as a service

New technology tends to come on to the market at a high price. Over time, and as production becomes established, the price falls. But with giant corporations turning out 300,000 cars per year per automobile plant to cover capital production costs, what hope is there for a radically different car in today’s global market? Mobility as a Service.

Riversimple, Re-inventing the car

The petrol car was shaped by and to a certain extent contributed to the shape of the 20th Century. This was a time of rapid and sustained change. Pioneers of the first combustion engine, the first Bentley, the first Mini and the first Ferrari were working against a back drop of horse-power, steam power, the discovery of oil, the industrial revolutionContinue Reading..

Riversimple Mark 2 Architecture

Here is a brief summary of the technology within our new Riversimple Mark 2 eco car architecture. Our engineers will explain more over the next few weeks…..

The Rasa is an eco car perfect for all those everyday journeys like the daily commute. With a range of 300 miles, it will suit those for whom a battery electric vehicle presents real challenges, whether that be access to charging points, keeping on the road without any enforced downtime at inconvenient times of day or simply expense.

The Rasa is light to handle, responsive and fun to drive. A nippy 0-60 mph in 9.7 seconds, it cruises at 60 mph and we have capped the speed at that level to deliver maximum range and efficiency.

We anticipate the cost per month for our eco car to be about the same as owning and running a basic mid-size hatchback.

It takes about three to five minutes to fill with hydrogen. The pump is similar to a diesel or petrol one, just locked into place on the car. Simply press a button to automatically refill. And the cost of the hydrogen is included in the service.

Unusually for an eco car company, Riversimple is keen to involve people in the design of both the car and the service, so we are running Beta Tests with a number of Rasas built specifically for this purpose. The Beta Tests will run throughout 2021 and much of 2022 in the regions of Monmouthshire, drawing support from the County Council and the Office for Zero Emission Vehicles (OZEV), and in Pembrokeshire as part of the Milford Haven:Energy Kingdom (MH:EK) project with support from UK Research and Innovation (UKRI).

Cenex Low Carbon Vehicle Event 2015 – We are on our way!

We are excited to announce that our new vehicle architecture is on its way to the Cenex Low Carbon Vehicle Event (9th/10th September, Millbrook, UK)

LCV is run by Cenex, the UK’s first centre of excellence for low carbon and fuel cell technologies with assistance from Supporting Partners including the Department for Business, Energy and Industrial Strategy, the Centre for Connected and Autonomous Vehicles, the Office for Zero Emission Vehicles, the Department for International Trade, the Advanced Propulsion Centre, the Automotive Council, Innovate UK, Zemo Partnership, Zenzic, the Society of Motor Manufacturers and Traders, and Connected Places Catapult.

Riversimple will be demonstrating its brand new vehicle architecture at this years event. Designed to be as lightweight and efficient as possible, the architecture will showcase how both the hydrogen fuel cell powertrain and structural efficiency can work hand in hand to create a low carbon vehicle. The architecture is designed using a carbon fibre monocoque chassis that weighs just 70 kilograms, a hydrogen fuel cell and 4 ultra efficient in wheel motors driven by the electricity produce in the fuel cell. The architecture will form the basis for our first roadgoing prototype that will use an ultra low drag, composite body

Hope to see you there!

The Alpha Build is underway!

It has been a hive of activity in the workshop (and at our suppliers) over the last few weeks. bringing all the part of the Alpha hydrogen eco car build together, here is a small taster of what we have been up to!

Our new body has been delivered, designed by Jim Router and produced by KS Composites, it is constructed using carbon fibre to provide unrivalled strength and lightness. The entire chassis weighs just 70kgs and will form the basis that the ultra efficient powertrain will be mounted on.

The in wheel motors will be fitted to the car and will use the electricity from the fuel cell to drive the car. They are in wheel so that they can be more efficient by reducing drivetrain power losses. They are mounted where the hub would be on traditional cars and therefore are unsprung mass, this means the car handles excellently when driven.

We are refining the powertrain and powertrain control software to ensure that that the car will be as efficient as possible and achieve its 300 mile range. Other arrivals include the dash board panels, wiring looms and the rear subframe.

Welcome to Riversimple

Welcome to our new blog! Over the last year we have been quietly planning and designing our next generation Hydrogen Fuel Cell (HFC) vehicle here at our R&D facility in Llandrindod Wells (Mid Wales, UK). We are really excited that our ideas are now coming to fruition and want to share the next stage of our journey with you all. Over the next few months we will be blogging about the build of our next generation hydrogen fuel cell car. The styling surfaces look awesome and the latest generation of our tech is already up and running in lab conditions. We really can’t wait to see it all come together into our Mark 2 vehicle. Of course Riversimple is so much more than just another car company – our aim is ‘mobility at zero cost to the planet’, so expect plenty of stories about the challenges of starting a truly sustainable mobility company from our eclectic and dedicated team. It’s not going to be easy, but we wouldn’t be here if it was!

All technologies need to be used to decarbonise as fast as we can and hydrogen cars offer people a valuable zero emission alternative to battery electric cars for those who will find charging them a challenge. There is very little behaviour change required to move from a fossil fuel car to a hydrogen car as they are filled in the same sort of way (at a pump in c. 3 minutes) and have similar ranges.

The UK has an abundance of renewable energy opportunities such as biomethane, wind and solar. Hydrogen provides a fantastic solution for the storage of this energy so that it can be used when needed, a step required to harness the full power of renewables. Cars and other forms of transport can make this commercially viable sooner, creating higher value demand for green hydrogen. With big energy companies, such as Shell and BP climbing on board, the future looks very bright.
