The car of the future seeks alternatives to oil on wheels. Electric-diesel hybrid cars transition compressed air engines, methanol ... evolve compete until fuel cell cars, which in turn generates electricity continuously with hydrogen stored in a tank. The water itself generated in the process serves as a coolant.
Hydrogen Current Status: Looking to maximize savings and zero pollution All these new solutions are a great savings over domestic cosmbustión engines suffered major losses in energy conversion. And so the engines based on hydrogen fuel cell electric power obtained in one step. In addition, residues of these cars are safe for the environment, as are reduced to water and steam thereof.

safer and more economical ways to manipulate the hydrogen which is highly explosive. On the other hand, lack the infrastructure and to develop a hydrogen distribution network.
Toyota takes the lead with hydrogen 
While Toyota test new prototypes of hydrogen, markets solutions of transition as the hybrid Prius, one of the green cars and modern at the most competitive market price.
makers Toyota has just introduced two new high-pressure tanks specially designed to carry compressed hydrogen in cars and with it, feed a fuel cell. The equipment developed by Toyota are very advanced and are made of composite material is very lightweight and extremely durable. Toyota have already calculated that its FCHV rolling pass to complete 300 km 330 km before refueling. If you bring the tank of 79 megapascals, can exceed 500 km.
One of the great achievements of Toyota has also been made to store hydrogen is highly explosive, in a relatively small and tight tank, because tanks for liquid hydrogen can be very heavy.
BMW: The first car produced in series hydrogen 
BMW 750 hL: first hydrogen car will be produced in series history, a car with a power of 150 kW, about 204 hp, and is capable of accelerating from 0 to 100 in 9.5 seconds and reach a top speed of 226 km / h.
Where will these cars on hydrogen? BMW plans to sell this product in 2010. Until then, their efforts will focus on
create a network of stations to supply hydrogen in collaboration with large energy conglomerates. Supplies will be automated which will take approximately three minutes to fill the tank.
not have it easy the manufacturer German to fight the battle, because the oil companies are not willing to go along with it, unless they find it a safe business. However, BMW goes further and is expected that by 2020 20% of its cars run on hydrogen. But do not end there Germanic group challenges, but also aim to achieve this element through a renewable energy source, which would complete a completely clean process. For now, BMW's commitment to solar energy as demonstrated by a huge central hydrogen fotovoltánica has built in California's Mojave Desert.
The German Government, which last week announced that allocated 5,000 million euros over the next 10 years to the promotion of hydrogen, the technology is expected to take 15 years to reach critical mass, after a rapid expansion
DaimlerChrysler: The alternative methanol DaimlerChrysler last November has presented his credentials in this competition with two vehicles:
NECAR-5: The fifth and most sophisticated version of the electric car hidden in a Class A
Jeep Commander 2: Silent and extremely ecological, but that Unlike the BMW 750hL, using methanol as fuel, a derivative of alcohol, to achieve the necessary hydrogen.
Germany for the giant American, the direct use of hydrogen is something ideal in terms of ecological levels actually used it in its previous prototype NECAR 4, but with a too large infrastructure cost. Therefore, commitment to the methanol, cheaper and easier to transport than liquid hydrogen, but more polluting. It can be marketed in four years and continues to be an effective solution until it gets better hydrogen directly.
Honda FCX: Domestic Energy Solution Station has a more efficient hydrogen fuel cell and a more powerful electric motors, totaling 130 kilowatts, ie, about 174 horses. Also large double autonomy to near 600 km on a single tank.
The new Honda FCX is complemented by the Honda Energy Station or HES which was filed last week in Spain under the name of Domestic Energy Station.
This device, which combines the concept of station and power plant uses solar energy and natural gas or methane to produce hydrogen. With the heat and the resulting gas station Domestic Energy produces fuel for the vehicle, and enough energy for 50% of household needs.
In this way, Honda was able to overcome the great obstacle that they encounter attempts to introduce hydrogen technology: the lack of a distribution network. By making each user almost independent, given time it develops the system
refueling stations.
Minicats: The alternative to compressed air cars Minicats
The inventor, Guy Negre says that consumes less than one euro per hundred kilometers, ten times less than a gasoline car. Operation seems simple: take the air, filters and compresses it into some bottles. During this process, use type carbon filters that remove dirt, moisture, dust and abrasive particles containing numerous air of cities. At the end of its cycle, emits clean air. The electricity needed for the process can be recharged via the mains.
