Many people criticize the electric cars that are not on a dedicated platform, which are primarily gasoline cars, on which it was adapted, sometimes awkwardly, with limited budget, an electric motor. Mercedes intends to refute these criticisms, but without a chassis designed specifically to electric power. The trick is to develop a platform that Mercedes calls multi drive, to signify that it accepts both a conventional gasoline engine, an electric powertrain powered by a fuel cell.

Mercedes has developed 2 channels traction totally different concept F 800 Style. Let’s first hybrid gasoline. Who is not entirely original, since it is an evolution of the concept of Vision S 500 Plug-in hybrid, which was already based on an evolution of the S 400 series hybrid. We thus find the V6 petrol 3.5 liter. With direct injection of new generation, he is more sober, power up to 300 hp. The electric motor is progressing much as his power increases to 80 kilowatts (109 hp).

The fuel tank is 45 liters, the lithium-ion more than 10 kWh, giving 30 km of electric range and 700 km of autonomy combined. This is fairly low for a limousine. The trunk then, is not really what is expected of a big Mercedes. Its capacity is only 440 liters. It is certainly much better than a Lexus GS450h (280 liters), but it’s even bad for families, as hybrid cars more environmentally friendly, offer less autonomy and less space for luggage, than diesel.

Second version, fuel cell (CAP), and again it is an evolution of an existing drivetrain also that of the F-Cell Class B CAP. This is good! The more standardization in new automotive technology, they will be more affordable. Nevertheless, this powertrain is perhaps a bit light for a big sedan with an electric motor only 100 kilowatts (136 hp). 290 Nm of torque all the same, but the speed is limited to 180 mph, which makes the F 800 concept style, the slowest of all Mercedes.

Yet the best of all the saloons of the star (equal with the F-Cell), since it is zero pollution. Its use never rejects anything but a trickle of water vapor, and 5.2 kilograms of hydrogen at 700 bar pressure cylinders that contain her give a range of nearly 600 km. These 2 chains traction will meet in the future in the Mercedes range, certainly in this decade … But we will first see the new generation of the Mercedes CLS. She is the F 800 ad, with lines surprising, since very different from the slender silhouette of the current CLS, the car that started the fashion for low line sedans. We’ll see soon what happens on the production model, probably this fall.

During the Winter Olympics Vancouver 2010 (from February 12 to 28), 20 hydrogen buses boarded the public to Whistler mountain resort (where various competitions are held).

These buses ecologists have been concocted by a consortium including Canada’s Ballard is. They are equipped with a hydrogen engine, a fuel cell (housed on the roof) and an electric battery. It is the Canadian federal and British Columbia who funded the project of 89.5 million.

The fueling station, located in the municipal bus depot, has a capacity of 26 000 liters!

This fleet of 20 hydrogen buses will still be outstanding after the Olympics: good news, ticket prices will remain the same for users.

The price of a hydrogen-powered buses is 2 million Canadian dollars (cons 500 000 Canadian dollars for a traditional bus). A significant investment that is well worth it!

The organizers of the Olympics and the Whistler ski resort and want to limit the impact of transport on the environment.

In Japan, the Mazda RX-8 Hydrogen has leased since 2006.  Athletes with mild grade: 109 hp must meet the prototypes.

The hydrogen rotary is conspicuous only by pasting on.

The prototype will demonstrate that hydrogen rotary engine and fit together well.

From the pipes flowing at RX-8 Hydrogen only water vapor.

The Mazda RX-8 Hydrogen was founded in 2003 at the Tokyo Motor Show presented.

Mazda uses the technique on tank vessels, the 350 bar handle. One filling is sufficient for approximately 100 kilometers.

The Antares DLR-H2 during its technical flight trial in June 2009 at Zweibrücken. The fuel cell is slung under the left wing and the hydrogen tank under the right wing – with a capacity of either 2 or 4.9 kilograms. The fuel cell system used to power the Antares delivers up to 25 kilowatts of electrical power, and when flying in a straight line, the aircraft only requires about ten kilowatts of power. In this situation, the fuel cell is operating at an efficiency level of approximately 52 percent.

Another new feature of the Antares is the way its fuel cell is connected to the main electric motor that powers the aircraft. The motor controller, developed jointly with Lange Aviation and with the College of Advanced Technology in Berne/Biel, is capable of taking in and controlling voltages from 188 to 400 V. Through the direct link between fuel cell and motor, efficiency is optimised while costs, reliability and maintenance costs are minimised.

The hissing white tank drops in aerodynamically favorable shape hangs under the wing of a glider. Antares DLR H2 is the Air Force, in a few minutes to the first official flight at the airport Hamburg-Fuhlsbüttel will take off. It is the world’s first public flight of a single fuel cell-powered aircraft – and therefore sends Hamburg’s First Mayor Ole von Beust personally some Greetings. He says “It almost like the first flight of Yuri Gagarin into space”.

The DLR’s scientists will continue to work closely with Airbus and Lufthansa Technik cooperate. The technology-yard, the Antares DLR-H2, at the Lufthansa base in Hamburg will be stationed, technically supervise.

The project H2BVplus, an H2-ignition combustion process as a possible cars propulsion of the future will be further investigated. With regard to performance and efficiency can be distinguished from conventional diesel interesting aspects derived. The H2-ignition concept is to increase the efficiency and specific performance is expected.

The technical characteristics of the Suzuki SX4-FCV are as follows. It has a reservoir hydrogen under high pressure (70MPa). Its electric motor develops a power of 68 kW. Its supercapacitors capture energy from regenerative braking. The SX4-FCV enjoy an autonomy of 250 km and a speed of 150 km / h. Its measurements? 4190 x 1730 x 1585 mm and a wheelbase of 2,500 mm. For comparison, it is still far from the performance of Nissan X-Trail FCV equipped with a fuel cell with hydrogen, with an autonomy of 500 km (see article).

Clarification: Suzuki has also introduced its SX4-FCV with hydrogen at the G8 Summit (bringing together heads of state of most industrialized countries of the World) held from 7 to 9 July 2008 at Lake Toya on the island of Hokkaido in Japan.

Developed and built the high-flying testbed project partners from Long Aviation in Zweibruecken. As the primary source of energy for propulsion is one of the DLR Institute for Technical Thermodynamics specially provided fuel cell system. This system is nearly identical to that used in aircraft fuel supply system for board and provides the electrical energy for the Long Aviation developed powertrain, from the power electronics, motor and propeller exists. The use of a highly efficient fuel cell (efficiency up to 52% electrically) with the hydrogen fuel makes driving this airplane CO2 released. The waste product is clean water.

It is expected that the pairing of the fuel cell with a very quiet and powerful electric propulsion small plane in comparison with piston-driven engines set new standards in the fitness level requires. The project impresses by bringing together interdisciplinary activities. To a very economical flight to allow the entire aircraft is technically optimized flow. The goal is turbulent air currents in all areas to be avoided.

Long Aviation, the company is making a long-standing experience with. The integration of the experimental vessel was both aerodynamically aeroelastic both a challenge by the solid experience of the Institute for Aeroelasticity of the German Aerospace Center, an optimal placement of the containers can be achieved. This is the dynamics of the airplane is not affected. The additional air resistance on the Antares 20E model series are less than 15% and with a potential additional burden of more than 200kg.

When the coupling of the fuel cell powertrain system with the new routes were also begun. The fuel cell system was designed so that it directly with the engine control unit can be connected. The components and saves costs and increases efficiency. Therefore, both the Institute for vehicle concepts of the DLR as well as the Bern University of Applied Sciences Biel and the Long Aviation an important contribution. A subsequent hybridization with a lithium-polymer battery will power the aircraft continue to improve. The result is a high-tech makers of a variety of architectures of fuel cell systems can absorb. These can then be luftfahrtrelevanten conditions such as pressure, temperature, acceleration and vibration tested.

For the first flight at the end of this year, a fuel cell system in cooperation with the firm BASF Fuel Cell GmbH (electrolyte + electrodes) and Serenergy A / S (Stack Subsystem) for the airline upgraded. That was at the Institute of Technical Thermodynamics alongside overall system architecture design and build a whole range of temperature and pressure measurements.

With a specially designed control architecture Algorithm shows this is a very good weight / performance ratio, an important criterion for the airline. Upon completion of the first tests, which are aimed at a maximum altitude and thus a minimal negative pressure to reach the fuel cell system developed for maximum efficiency in converting fuel energy into electrical energy to guarantee. Now the entire fuel cell system used and the hydrogen tank weigh about 100 kilograms. Thus, only half of the additional burden exploited. This offers a high potential for the aircraft for possible flights record (height, width, etc.) compartment.

To make a comparison to be able to stand further fuel cell systems and architectures prepared to your airworthiness to be investigated.

The base used to develop these prototypes is well known is that the Grand Scenic. But there is a substantial difference between these protos hydrogen and a Scenic standard height. Renault has clearly not yet know-how Honda, which has launched production of the FCX Clarity, he had slightly (6 cm still) raise its Scenic to enable it to accommodate a technology for which he had, it is true, not been designed. There is also inlets different, a PAC to need more air an engine combustion, it has expanded those of Scenic.

But alongside this, to understand these differences, a surprising thing, a very small thing, the logo. The Scenic indeed, is Renault-Nissan badge. There are perhaps who remember the first prototype Renault PAC, a Laguna break at the end of the last century. It was conducted by the manufacturer french. While it is a collaborative effort of 2 marks Allied, which is not an evil, but emphasize that Nissan has provided the most important, namely the CAP and Lithium-Ion battery. Elements imagine that very close to those of Nissan FCV.

The architecture of the vehicle is divided into 3. It is under the hood the electric motor and transmission (one report, move forward or backward), accompanied by any power electronics that control the car, and an air compressor. The air is sent to the CAP, located in the center of the car, under the front passenger seat, which combines with hydrogen from a tank located under the floor of the trunk, near the battery. This architecture is not ideal. The solution Honda or GM, to use a large central console, to house elements, is definitely more skilled.

But these manufacturers have chosen to develop a dedicated architecture, where Renault has chosen to adapt the existing platform of Scenic. With this constraint, it has been fairly successful, since habitability is fully preserved. Only the trunk is somewhat reduced, by a raised floor. It is therefore aboard a Scenic normal, ie a well-designed car at the interior, albeit with a modified instrumentation, or more exactly appropriate.The revolution and the regime gives the electric motor, the gauge gasoline has become an indicator of pressure hydrogen, while the indicator energy is available on the navigation screen.

The electric motor has a power of 90 kW, which seems sufficient, but not exciting as long as this Scenic hydrogen is 300 kg heavier (!) That the diesel model series (dCi 130). It is 1850 kg on the scale, and much. It may still, of course, appreciate the flexibility unmatched electric motor, but with a top speed of 160 km / h and an acceleration of 0 to 100 km / h to 14 “65, there is no What complacency. It is true that there is no need for athletic performance to validate and test the technology and hydrogen CAP, but in competition, the GM Sequel goes from 0 to 100 km / h in under 10 seconds.

So if this prototype is a good effort on the part of the brand in diamond, which was late, it shows that Renault follows, but remains behind the leaders of hydrogen as GM, Honda or Toyota. To compensate, we look forward to the future electric Renault. The earlier, or Kangoo Express, had not been very successful.But that was partly due to the network, which had been unable (or unwilling) to make the necessary effort to promote them. With a strong commitment by Carlos Ghosn himself for future Renault and Nissan electric cars Series scheduled for 2010/2011, we do not have many doubts they are the best globally. Finally green rimera with Renault!
