DLR succeed solar hydrogen production

Scientists at the German Aerospace Center (DLR) to produce hydrogen in a 100-kilowatt pilot plant by solar energy and regenerative CO2-free

Hydrogen can be used as fuel in the future a significant contribution to the energy industry afford. Scientists at the German Aerospace Center (DLR), it is now the first time succeeded in this important energy source in a 100-kilowatt solar pilot plant through regenerative CO2 and thus free to produce.

Solar energy is by far the most widely available energy resource on earth. Hydrogen is again with its high energy density is an excellent energy source, also arise during its combustion only water and heat. Already more than six years deals the Solar Research of DLR-Institute for Technical Thermodynamics in the framework of EU projects Hydrosol I and II with the development of innovative reactors for solar, thermo-chemical water splitting. With these reactors is water by solar energy – without the detour via the electricity – into hydrogen and oxygen divided. Now could so far in the 10-kilowatt power range of research results shown successfully on a 100-kilowatt pilot plant to be transferred.

The Spanish on the Plataforma Solar de Almeria (PSA) plant is installed with a novel solar reactor, and it was only in the spring of this year officially inaugurated. With their size and automation, it is already an important prototype for future industrial plants dar. DLR developed the reactor technology for the facility. The reactor is concentrated solar radiation at 800 to 1200 degrees Celsius control. At these temperatures will then won hydrogen from water.

“Solar Hydrogen is CO2-free energy

Regenerative production of hydrogen from solar energy and the associated storage of solar energy into chemical energy that are of great technical and economic interest to the energy industry. After a thorough qualification of the solar thermal tower plant in the summer of this year, the plant recently for the first time with Solarabsorbern equipped, by a special coating are able to divide water and thus CO2-free hydrogen to produce.

The path to commercial application

The successful solar hydrogen production represents a significant milestone in the ongoing Hydrosol II project which, given the already initially achieved the hydrogen yields far exceeded expectations. In the next few months, the tests for hydrogen production on the so-called SSPS Tower (Small Solar Power System) of the Plataforma Solar de Almeria continued and intensified. The focus is primarily the optimization of operating conditions and the efficiency of the plant. Further tests with alternatively coated Solarabsorbern should then pave the way to the most suitable materials show.

The design of the 100-kilowatt pilot plant based on a modular concept. It is a further upscaling of this technology to the megawatt-scale readily available. This can be achieved by multiplying the existing reactor units and connecting Heliostat fields (mirror-burning fields) of appropriate size, as they already have, inter alia, in Spain to generate electricity commercially used to happen.

The hydrogen yield of the DLR is proceeding with thirty percent in the pilot plant considerably, according to DLR will in future installations “up to 80 percent” yield possible.

The project will Hydrosol by an international consortium with participants from Germany, Spain, Greece, Denmark and Britain carried out. The research and development work on Hydrosol I have been because of the potential far-reaching consequences, including the Descartes Research Prize of the European Union and the Technical Achievement Award from the International Partnership for the Hydrogen Economy excellent.

The DLR Institute for Technical Thermodynamics in solar research is one of the world’s leading institutions in the field of concentrating solar systems. The aim is, together with industrial partners concentrating solar systems for heating, electricity and fuel production for sustainable energy development. Besides testing facilities and laboratories in Cologne and Stuttgart, the team of researchers by a permanent delegation on the spot access to the biggest European test center for concentrating solar technologies, the Plataforma Solar de Almeria in Spain.

The first project was HyWay today at the annual meeting presented: In this North Rhine-Westphalian – Dutch joint project involves the development of a bus line with fuel cell propulsion. The 18 m long articulated buses will be around after a year of development the trial operation in the area of Cologne and Amsterdam record. At both locations will have two vehicles used. From North Rhine-Westphalia participate in the company Vossloh Kiepe GmbH in Dusseldorf and the Hoppecke Batteries GmbH & Co. KG from Grayson. They are supported by the University of Cologne and Aachen University. “I am delighted that we have this highly innovative project together with our friends from the Netherlands to bring forward,” said Dr. Baganz.

“In the fuel cell technology takes Nordrhein-Westfalen has been a long time a top place,” said Dr. Baganz. “Especially in this area is clear that North Rhine-Westphalia as innovative energy and economic metropolis pioneer designers and the future is.”

An important milestone on the HyWay is the 18th Weltwasserstoffenergiekonfererenz WHEC, in May 2010 in Essen will take place. Dr. Baganz: “The many successes already achieved in the field of fuel cell and hydrogen technology in North Rhine-Westphalia and Germany, we want within the framework of the 18th World Hydrogen Energy Conference in Essen present. “You can not just guests at the conference, but also the visitors of the European Capital of Culture eating these forward-looking technology in North Rhine-Westphalia experience.

The focus of the annual meeting stood alongside international projects including the activities of the competence network Fuel Cell and Hydrogen EnergyAgency.NRW of North Rhine-Westphalia and its approximately 350 members. “The network is one of the largest technology platforms of its kind in Europe. We maintain close cooperation with our partners in Germany and Europe and will continue as a competent partner in the programs of the federal government and the EU Commission involved, “said network director Dr Andreas Ziolek. North Rhine-Westphalia does not least because of the high commitment of the competence network Fuel Cell and Hydrogen NRW its position in this field of technology can further expand.

The North Rhine-Westphalia Ministry of Economic Affairs, together with the science ministry so far over 80 projects with a total grant of 82 million euros for a total of more than 133 million euros.

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!
