Cella Energy is developing the Hydrogen Bag™ that contains micro-fibres. The fibres resemble white tissue paper and can be packaged in any container or even in clothing. There is no need for a metal canister because the hydrogen is stored at normal temperatures and pressures, and is safe to handle in the open air. Previously we have discussed the Cella Energy markets of cars and rockets.
The way the hydrogen is supplied has held up the adoption of these fuel cells up to now because hydrogen storage has only been possible in hydrogen cylinders. These metal cylinders present safety risks and are not practical for large scale market adoption
