Renault Scenic ZEV H2

Renault has very large projects in the electric vehicle, but he also sees further. In every sense, including that of having more autonomy through a fuel cell (CAP) powered by hydrogen. With a reservoir pressure of 350 bars, the autonomy of the Scenic ZEV H2 already reached 350 km, and although Renault has not done, it would be possible to put a reservoir to 700 bars of pressure, for bring to more than 500 km. The 350 bars nevertheless sufficient to validate the technology, more promising than any electric batteries, and with even more easily than Renault may not station outlet of hydrogen at 700 bars on its test centre. Renault Scenic ZEV H2

Renault Scenic ZEV H2The 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. Renault Scenic ZEV H2

Renault Scenic ZEV H2The 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. Renault Scenic ZEV H2

Renault Scenic ZEV H2The 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!

The new Toyota FCHV drive north of the earth

Honda has announced that mass production of fuel cell vehicles “clarity” is a feeling of future automotive debut in style. F1 race, similar to rival Honda fuel cell vehicles will also work hard, because Toyota can not keep silence. It would be, F1 funds to take over the development of fuel cell vehicles, Toyota’s recent trend that is worrisome?

Previous reports, as the Hokkaido Shibetsu Toyota’s vast small test course “iQ” we were able to hold the steering thing, but when this latest fuel cell hybrid vehicle, “Toyota FCHV-adv (Fuel Cell Hybrid Vehicle – advanced) “could also test-drive.

Toyota FCHV is like Honda’s new platform is a nonissue because we have not given, but the contents have been steadily evolving. Toyota to develop a lot of people see the situation is quiet SUV “Krueger”, already has completed the production and sales of the model may be used by. Somehow it felt old. Hokkaido test-ride event Okamoto, who was vice chairman of Toyota’s “do not always make the body, so please be patient,” he added. The most important thing is the performance of fuel cell reliability of the cost.

Asahikawa in Shibetsu test from the 100 km road course FCHV to drive. ETC with Krueger also enjoy the highway. The passenger seat Ishiguro, Chair of the developers sit.

he fuel-cell vehicles have a hybrid system. Nickel-metal hydride secondary battery and fuel cell body (stack) combination.Stack becomes easy to replace internal combustion engines. In other words, you accumulate savings to electric box-like secondary battery, a stack of electrical power generation system is paired with the other two. The Prius has the same meaning.

Toyota FCHV-adv

300 ~ 500km rather than the medium-range game is?

Asahikawa in Amsterdam to leave. And a stop signal, fuel cells will automatically shut down. Unlike the internal combustion engine stops, originally quiet stack is shut down, the feeling is not idle stop. And when the brake energy regeneration, but can not originally high energy efficiency (energy consumption is low), meaning the recovery is extremely high. Less money from a large portion of your change.

But the model is the relationship between secondary battery capacity, many of the regenerative energy recovery can not. The next step is to practical use lithium-ion batteries until the recovery rate is low. Therefore, even if actually running the engine brakes feel very strong. This recovery rate is low.

700 low-pressure hydrogen gas fuel is using, but this time as there is no hydrogen station areas, how the hydrogen to fill it out? So the idea is hideous mobile hydrogen station. Iwatani International Corporation of Japan has undertaken a hand.

Honda has 350 hydrogen gas pressure system will be stuck with the world becoming a standard atmospheric pressure is 700. Kruger Toyota FCHV SUV is a vehicle height is high, so high-pressure hydrogen storage tank to the floor. Highly efficient hybrid system and a combination of the stack, and 700 with a low-pressure fuel FCHV is a range of more than 500 km that is secure.

Ride in the passenger seat while driving Organizer Ishiguro, a variety of stories blast. Osaka to Tokyo’s Odaiba hydrogen from the station until without refueling (lubrication oil so the word is also incorrect) to cover the whole of it. Also, Toyota will run only secondary battery EV (electric vehicle) and fuel-cell vehicles to differentiate how the idea? The answer is that distance and duration. For example, 200 ~ 300 km run in the EV, 300 ~ 500 Km of fuel cell vehicles, 500 ~ 1000 Km of internal combustion engines and hybrid might be considered.

With an output of 90kW fuel cell

Honda has stuck with the 350 Pressure is the reason for this is to think of hydrogen filling. Excessive pressure of 700 and it is not practical. Honda is certainly plausible explanation.

Pressure 700 manufacturers from around the world to believe that immediate standard is 700 atmospheres, you can study, because we can reduce later. Ishiguro, as Chair of Toyota’s my opinion “about 500 atmospheric pressure at the optimal solution might have,” he said in the study stage in the high hurdles mean that there would be a good idea.

Since evolution of the FCHV is very cold areas where there is work that has been confirmed. Organizer Ishiguro himself all over Canada and the Arctic Circle, close to the cold-start test and the minus 37 degrees and it was confirmed that the work.

Get on the freeway and the performance of the newly evolved FCHV shock. 90kW higher output in the design of a new generation of high-performance fuel cells to beat him hurtling to earth in the north. “Dental and well” is an expression of literary, but it is quiet, tire and wind noise, the lone road only hear the sound.

Output 90kW how big? Have been installed in my home for a family of fuel-cell stack is only 1 kW. This compared to how energy is used vehicle or vehicles that would be understandable. Toyota’s fuel cell vehicle that is one of about 50 households MAKANAE power to them.

Hydrogen energy is becoming a source of intuition

I felt attracted to fuel-cell cars is almost the same time Toyota and Mercedes are the future of automotive fuel cell vehicles is a powerful message out from the start.

Attracted more than anything is that the hydrogen fuel. It was Mechanical Engineering students to teachers is a pioneer in the hydrogen engine. The premises of a prototype of a hydrogen engine vehicle is “PUTSUNPUTSUN” BAKKUFAIYA out with a big, run, it was left to the head. Is the car’s hydrogen energy and intuitive feeling was that instead of hydrogen-burning hydrogen engine, hydrogen fuel cells, hydrogen power can be interested.

My steering wheel is the first time in 1996, “RAV4″ made the EV-based early stage. Tokyo Gas, the site of a test ride. At that time, technology is the hydrogen-absorbing alloy metals (rare earth) type. So I ran and the weight is too groggy to remember.

But remarkable progress has been made in 2001, the Prius hybrid system that combines the same. And finally minister in December 2002 to develop fuel-cell vehicle certified by the Cabinet and Government / leasing companies have started selling.

Toyota’s efforts to follow this has been the Honda and DaimlerChrysler and General Motors (GM). Toyota will further fuel cell bus in collaboration with Hino Motors, Daihatsu and Nissan’s fuel cell car developed. Honda differences in company size and the development of the road map is somewhat different.

Fuel cell vehicles and electric vehicles colleagues in the broad sense

The FCHV-adv hydrogen tank is two-fold increase in the fuel economy mode and that can travel 840 km. The safety of the car violently crushing a hydrogen tank would also be protected so strongly built on it.

What is worrisome is sent to stack the hydrogen leak of hydrogen in the pipeline. The FCHV hydrogen exclusively from side to side, before and after the crash sensors to place the cabin at the top of the stack and the hydrogen tank and a hydrogen leak is equipped with sensors to detect. As a result, hydrogen and hydrogen tank leak may have automatically closed the valves.

Japan in September 2008 from the sale of some government agencies to lease began. Priced at 7,760 US$ per month for 30 months and lease expensive, but still, someone is not going to use the attention of the world.
Toyota, Honda and Nissan continued to fuel cell vehicles to show for his attention, but I wonder about the electric vehicle is equipped with a lithium-ion batteries are completely separate working on it. Fuel cell vehicles and electric vehicles in the broad sense of camaraderie. In that sense, the Japanese fuel cell vehicles and electric vehicles, the roadmap is a different feeling in there?

Electric vehicles and fuel cell vehicles or energy from the viewpoint of the jurisdiction of the Ministry of Economy, Trade and Industry, Japan’s fuel-cell vehicles to conduct field trials “JHFC (hydrogen fuel cell demonstration project),” fuel-cell-related private companies Making “FCCJ (Fuel Cell Commercialization Council)”, and the spread of electric cars is another program that is working hard to understand.

Withdrawal from fossil fuel and renewable energy to achieving a sustainable society is possible. Ishiguro, Chair of the sides to listen to Toyota’s technical department in the diversity of electric drive technology while fully understanding the technology and scrub.

TAZ on ZBT opened on 15.09.08

It is unique in Europe and was by many industry partners who develop fuel cell products, repeatedly suggested: NRW-Minister of Economic Affairs Christa Thoben opened on 15 September 2008 nach nur eineinhalbj├Ąhriger Bauzeit das TAZ, das Test-, Applikations- und Assemblierungszentrum am Zentrum f├╝r BrennstoffzellenTechnik (ZBT gGmbH) in Duisburg. September 2008 after only eineinhalbj├Ąhriger TAZ the construction period, the testing, application and Assemblierungszentrum at the Center for fuel cell technology in Duisburg.

“To both fuel cell components as well as overall systems rapidly to the market, various fields of activity around the fuel cell bundled,” said the minister. The working fields of the new test and application center include production engineering, installation, commissioning, testing and evaluation of fuel cells, components and complete systems. All this with the goal of fuel cell technology economically and quality continue to develop.

“This unique pan-European offer complements the already excellent service offering North Rhine-Westphalia as a European fuel cell center. Unique is the concentration of diverse areas around the new products, “said Thoben.

With this new building project at the University of Duisburg-Essen, the strategic competence of North Rhine-Westphalia as an important energiewirtschaftliches and energietechnisches center in Germany consistently developed. Already today, the services of the ZBT by the industry in high demand. It is assumed that the institute with the help of the TAZ further long-term collaborations with industry partners will enter into to the fuel cell technologies with them to market and develop competitiveness. The establishment of a separate fuel cell production is not planned, which would be driven by the business partners with the support of the ZBT be realized.

The fuel cell and hydrogen technology on one of the promotion and development priorities of the provincial government in the energy sector. The activities of the country are under the established in 2000 “competence network fuel cell and hydrogen” the EnergyAgency.NRW organized and coordinated.

Together with the Ministry of Science, the Ministry of Economic Affairs so far over 80 projects with a total grant of 80 million euros for a total of more than 130 million euros. The ZBT since its founding member of the competence network, which is about 350 to a large extent medium-sized enterprises and research institutes. The aim is to the existing powers for the development of fuel cell systems and components as well as the production, storage and transport of hydrogen together more closely than before and new fields of competence to identify them.

Minister Thoben: “The many successes already achieved in the field of fuel cell and hydrogen technology in North Rhine-Westphalia and Germany in 2010, we want to under 18 World Hydrogen Conference in Essen present. “To meet the high expectations of this conference needs, a new project, the NRW Hydrogen HyWay of Aachen on Cologne, Dusseldorf, Duisburg and Essen to the northern Ruhr area. Under its umbrella project, over 40 new project ideas, which currently concrete form. These include infrastructure, vehicle fleets, stationary and many special applications of fuel cell and hydrogen technology.

Then 2010 not only the guests of the World Hydrogen Conference, but also the visitors of the European Capital of Culture Food fuel cell and hydrogen technology experience in North Rhine-Westphalia.
