Hydrogen storage powder from a quick, simple reaction

24.06.2008
Chemists in the US have developed a simple reaction to make ammonia borane – a powder more hydrogen-dense than even liquid hydrogen. Their one-pot synthesis of this promising hydrogen storage material is reported in the first issue of the new Royal Society of Chemistry journal Energy & Environmental Science.

Hydrogen has significant benefits as a fuel of the future: potentially renewable and sustainable, and, as hydrogen fuel cells emit only water, a green alternative to other more polluting fuels such as hydrocarbons like petrol.

Storing hydrogen safely is tricky, however – pressurising hydrogen gas is potentially dangerous for everyday use, and it can only be stored as a liquid under cryogenic conditions.

Chemists like Tom Autrey from Pacific Northwest National Laboratory, US, are addressing the problem by designing materials to store hydrogen safely, such that it can be released at will to power a fuel cell.

Ammonia borane (AB) is a stable white powder which releases hydrogen gas upon heating. Its use as a hydrogen storage material has been hampered by difficulties in making the powder in reasonable yield, but the new research further increases its promise.

Autrey and colleagues discovered a “one-pot” method of making AB while studying its decomposition pathways. He said the group was “pleasantly surprised that under relatively simple reaction conditions the ammonia borane was formed in very high yields.”

The group is currently looking at scaling up the reaction to an industrial level. Autrey says the next challenge is to “recycle the solvents to provide the most economical route to synthesise this promising hydrogen storage material.”

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
