Hydrogen
Hydrogen seems to be the logical fuel for this planet. Here I will try
to summarise the current state of developments. The areas I will follow
are these:
2009-04-24 Hydrogen from glycerine
Hydromotive, a subsidiary of the Linde Group, has announced that it is to build a plant at its chemical site in Leuna, Germany, to produce hydrogen from glycerine. Dr Valerie Dupont, a senior lecturer at Leeds University, commenting on the announcement, suggests that the Linde process suffers from a number of limitations including the need to couple the plant with an existing purification stage with a steam methane-reforming plant to achieve a 100 per cent hydrogen gas product stream. Dupont is investigating a more novel process at Leeds University called 'sorption enhanced catalytic steam reforming', a process that she has evaluated experimentally in a continuous flow fixed-bed reactor. Dupont's process operates near atmospheric pressure unlike the Linde system, which operates above 28 bar.
Also unlike the Linde process, the novel "sorption enhanced steam reforming" process makes use of a commercial Ni-based catalyst and a carbon dioxide-sorbent such as dolomite or hydrotalcite to perform the steam-reforming reactions and in-situ carbon dioxide removal.
Vehicles
2009-02-01 Mitsubishi will bring two of its MiEVs (Mitsubishi in-wheel Electric Vehicles) to the Melbourne Motor Show on February 27, and afterwards will make a promotional tour of Victoria, New South Wales, the ACT, Queensland, the Northern Territory and South Australia. There is a high liklihood that the 4-seater MiEV will be in showrooms by 2010. Whilst the two cars are all-electric, Mitsubishi have proposed hydrogen and hybrid versions. Mitsubishi started development on the MiEV in 1995, and the core technology is the wheel, motor, disc-brake and suspension assembly.
Storage
Fuel Cells
2009-02-06 A team led by Liming Dai at the University of Dayton, Ohio has discovered that nitrogen doped carbon nanotube bundles can act as a catalyst resulting in a fuel cell that produces up to 4 times as much current as a cathode incorporating platinum nanoparticles. The research might lead to cheaper, longer-lasting hydrogen fuel cells. Platinum is "poisoned" by carbon monoxide, suffers from degradation in performance due to nanoparticle aggregation and is costly.
