The simplest molecule presents the best opportunity for energy. With global energy demands projected to rise 66% by 2030, the world desperately needs alternatives to fossil fuels. Hydrogen power, a recent media phenomenon, presents an enticing alternative – one whose development reaches much further back than most imagine. -When people hear ‘hydrogen power,’ they don’t realize that we’ve been working on it for 25 years, says Trygve Riis, the Norwegian chairman of the International Energy Agency’s Hydrogen Implementation Agreement (IEA-HIA). -The world has already made significant progress in hydrogen production, storage, distribution, and safety.
Riis spoke at a press briefing in Washington, DC, where he unveiled the IEA-HIA’s 25th anniversary report, In Pursuit of the Future: 25 Years of IEA Research Towards the Realisation of Hydrogen Energy Systems. "Hydrogen is one of the few options we have for meeting energy demands without increasing global carbon dioxide emissions,” said Giorgio Simbolotti, PhD, an IEA program officer who also spoke at the briefing.
In 2004, governments worldwide will spend about $1 billion (US) on hydrogen research and development; corporations will spend another $5 billion (US) – both figures all-time highs. Much of this investment is spurred by the HIA’s drive to develop ’baseline’ hydrogen technologies. "We have an ambitious vision, but the challenges are significant, said Riis. The first challenge is production. Today the world produces roughly 40 million tonnes of hydrogen per year, most used for making ammonia and, ironically, for refining fossil fuels. If used for energy, the world’s annual hydrogen output would satisfy just 0.1% of the world’s energy needs," said Simbolotti.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
