The technology of hydrogen storage progressing well!

Vehicles equipped with a fuel cell with hydrogen, under development now, represent a promising alternative! Here’s good news concerning them.

The center of Ripault CEA (The French atomic energy commission) has developed a technology for storing hydrogen which won best European performance. The container in question had posted the best results in terms of durability and safety: it is part of the European project StorHy (Hydrogen Storage Systems for Automotive applications, see article). This technology has been fully realized in polymer composite materials: it could equip future vehicles running on hydrogen.

hydrogen storage progressing
The CEA says that among the various storage technologies embedded studied (solid storage, cryogenic and hyperbaric), experts from the European Commission and representatives of 40 European partners (both industrial and academic) project took stock of 54 months of development dedicated to storage technologies for hydrogen. These tanks, developed in partnership with the manufacturer Ullit, storing hydrogen in gaseous form.

The inner part of the shell (the liner), ensuring the sealing of hydrogen, is made of polymer as an innovative synthesis and processing simultaneously. This technology has been the subject of patents by the CEA and Air Liquide and is licensed to the company ULLIT for its industrialization. As for the external composite hull, it provides resistance and mechanical protection. It is made by filament winding and uses materials from aerospace such as carbon fiber.

CEA stressed that this technology is now the only meet three main criteria from the European specifications for embedded storage to 700 bars:

life: to represent their aging over the life of a vehicle, the ECA reservoirs have proved their resistance to more than 15 000 cycles of filling (20-875 bar) without any significant loss of properties (standard);

sealing the leak rate reservoirs ECA was a minimum 20 times less than the requested value by the standard (1cm3/L/h);

Safety: CEA tanks have demonstrated their resistance to internal pressure above the burst pressure fixed by the standard (1645 bars, almost 2.5 times the pressure of service).

The CEA said that the use of three reservoirs compact, with 3 times 34 liters of internal volume, allows boarding nearly 4.5 kg of hydrogen. This configuration allows you to explore with current technologies autonomy of around 500 km for a family car with a fuel cell PEMFC 70 to 80 kW.

The ECA continues his research within the ANR, of OSEO and the ‘Joint Technology Initiative on hydrogen European: they are intended to accelerate the industrial maturity of such reservoirs and facilitate their integration into a vehicle ( optimization of stored energy densities, establishing connections and sensors for maintenance; adaptability of the shape of the tank to the vehicle; integration into a complete system CAP and lower costs).

Boeing will fly through the new generation of biofuel

After cars, airplanes take up sustainable biofuels!

Boeing and Air New Zealand reported that a demonstration flight to sustainable biofuel will be made on a Boeing 747-400 from Auckland on 3 December 2008: one of the four RB211 engines from Rolls-Royce will operate in part through a new generation of biofuel-based jatropha, commercially viable.

Boeing biofuel
The process is as follows: a processing technology for fuel developed internally by the company UOP has helped convert the crude oil of jatropha bio-fuel. It is thus the first large-scale production of a biofuel for aerospace applications. The technical team of British engine manufacturer Rolls-Royce has tested it conducted a campaign full laboratory testing to ensure compatibility with jet engines now in service and its compliance with the conditions of use in aviation. Announced its strengths? A good performance, a very low freezing and good energy density.

To address the jatropha crude oil, the team used the technology of “green fuel” developed by UOP and methodologies based on hydro commonly used to produce fuel for transport. In the process, hydrogen is added to remove oxygen from biomass, resulting in a bio-derived fuel that could replace the kerosene used by the aviation industry.

It is possible to cultivate jatropha under very different circumstances: it produces a seed that contains a lipid oil inedible, which allows the extraction of fuel to manufacture. Each seed can produce 30% to 40% of its mass in oil. The oil used to create fuel for the Air New Zealand is based on non-arable land located in south-eastern Africa (Malawi, Mozambique and Tanzania) and India.

The goals: to identify and exploit the primary source of biofuel sustainable scale for civil aviation to reduce fuel consumption and emissions generated by aircraft; create a range of new generation biofuels that can be associated with Classical kerosene (Jet A) to improve the environmental performance of aircraft.

In the context of sustainable mobility and alternative fuels have the future ahead of them, whether on roads or in the air!

DWV looking for the best young scientists from the area of hydrogen and fuel cells

Also for the year 2008 the awards back to the DWV Innovation Award Hydrogen and Fuel Cell to young scientists. The now-established tradition has become an annual award goes to the best Diplom-/Masterarbeit from Germany or dissertation on the subject of energy or hydrogen fuel cells, together with all ancillary areas.

It is the high level of competition, which is in the applications and the excellent work of recent years establish, in any case be kept. John Toepler, chairman of the DWV said:

“Not only the excellent work of recent years, but the other candidates are evidence of a very intensive and successful work at German universities in this field is done. That is the basis that the average consumer will one day also affordable, reliable and environmentally friendly products can buy. “

The exact conditions of participation can be found on our website www.dwv-info.de (left column under the Innovation Award), or we will send them to you on request. The choice among the candidates takes place in early 2009 by a jury of university teachers from the ranks of the association. The handover of prices, coupled with presentations of the prizewinners, is part of the monitoring program of the next Ordinary Meeting of DWV on 12 May 2009 in Wolfsburg.

What is tuned to alternative car drives?

On 6 and 7 November VDI organized together with VW’s session “Innovative vehicle drives” in Dresden. This was about hybrids, hydrogen fuel cells and electric cars. And what came out? When the slogan “plate instead of tank” the flowers dreams of politicians from bio-based fuels wiped off the table, they were quickly two other alternatives at hand, namely hydrogen fuel cells and “of course!” The electric car.

Moreover, the German automotive industry – again, naturally! – The hybrid sleepy, and only Toyota had the ancient idea again to promote daylight. In Dresden brought the speakers all the wonderful ideas of a bright, emission-free car again in the future reality.

That the hybrid drive, combining a combustion engine with an electric drive, in the metropolitan traffic and on short routes and save fuel liquid against electric can enter, we will be known. However, its price, which, although large and expensive cars can be reasonably accommodated, but hardly inexpensive small. It is the savings effect is relatively modest, if not deep into the tricks draw wants. On long-haul, on the other hand, it is indispensable to the combustion engine,
the consumption behavior determined.

The talks in Dresden showed what we could do everything to the electrical part to integrate into the car. Meanwhile, Mercedes presented its first “mild” hybrid in the S 400, which next spring will be offered. Despite the restriction on a minimum of additional parts and a small lithium-ion battery, the electric drive is not allowed, the extra weight is 75 kg. Nevertheless, the reduction in consumption in the NEDC to 7.9 l/100 km for a 3.5-liter V6 gasoline engine considerably and represents the engineers made an excellent witness.
