The United States and Europe have invested billions of dollars and euros in recent years in research and development with the goal of using hydrogen as a fuel for cars. Despite the efforts, the results have appeared, with the placement of hydrogen fuel cells in cars is more difficult than imagined at first.
So, when an approach doesn’t work, it may be best to review the plan. That’s what’s making the Riversimple, the emerging United Kingdom. Instead of inserting the tank of hydrogen, fuel cells and electric motors within a traditional car, the engineer and businessman Hugo Spowers took this Powertrain, saw what he could provide in terms of performance and autonomy, and designed an entirely new car around.
The result is the shallow, that doesn’t impress the beauty, but is able to run 480 km without refuelling more than most hybrid and electric vehicles today-because it was born very light, requiring 10 times less power fuel cells.
Like all electric car, the Shallow shows force in acceleration, but the technological innovations appear in time to use the brakes. In place of the traditional friction brakes, disc or drum, the car has fully electric brakes.
Then press the brake pedal what occurs is a reversal in the electric motors-are four, one on each wheel. In addition to slow down, it turns the generator engines, leading to the extreme the principle of regenerative braking-there is also a friction brake that can be activated in emergency situations.
All the vehicle’s kinetic energy is transformed into electricity, which is stored in a supercapacitor, a kind of drums able to release large amounts of energy very quickly. This extra energy is used in the acceleration, since the production of the fuel cell is continuous and smooth, more accustomed to cruising speeds.
While a car like the Toyota Prius retrieves approximately 10% of the kinetic energy in its regenerative braking system, the Rasa takes advantage of 50%.
One of the major obstacles to the adoption of hydrogen as an automotive fuel is the tank which needs to be thick and too heavy because the hydrogen molecules are small and cut through any material. But the new prototype achieved a greater autonomy by weight than vehicles using lithium-ion batteries.
However, while the electric vehicles already have taken all over the place, where they can recharge, hydrogen vehicles still will depend on the creation of hydrogen and fill the tank of hydrogen can be tricky.
