Cella Energy, a UK-based energy company, announced big plans for hydrogen storage in early 2011, and is now beginning to deliver on its earlier promise. Hydrogen, as desirable as it is for use in transportation, presents many hurdles in its use. Creating an infrastructure for its distribution has been a major impediment so far, but Cella hopes to overcome that with its nanotechnology pellets that can be distributed, transported and used much like fossil-fuel liquids. Cella highlights the fact that the hydrogen is stored in low-pressure form at ambient temperatures and can be handled safely in the open air (something that can’t be said about gasoline, for instance). It benefits customers by being able to use existing distribution networks and …
