| Hydrogen Storage introduction
Hydrogen Production
Electrolysing water is the favoured technology to replace the present
industrial method of reforming fossil fuel derived hydrogen. Electrolysis
methods are well proven and domestic scale electolyser units are now entering
the consumer marketplace. However, many believe that increased research
investment could produce a new and more efficient way to release hydrogen
from water.
Biological Hydrogen
There are various methods that hydrogen can be produced biologically.
Landfill gas and other biomass treatments can produce hydrogen directly
or provide feedstocks such as Syngas and other hydrogen precursors. Experiments
with various natural, mutant and GM strains of microorganisms have demonstrated
potential for the future cultivation and processing methods which could
produce pure biological hydrogen.
Hydrogen Storage
Efficient Hydrogen storage is one of the important areas of ongoing research
required if a hydrogen focused economy is to develop. Compressed and Liquid
Hydrogen has been stored, transported and used for a long time, but other
concepts are new and may offer improved suitabililty for the transport
and consumer goods sectors. Metal halides options are proving both expensive
and heavy, whilst carbon nanotubes are proving difficult to manufacture
large scale. At present no one has managed to acheive a higher density
of hydrogen than is already contained in petrolium.
Fuel Cells
Fuel cell technology, which allows hydrogen gas to bond back with atmospheric
oxygen to create electricity and fresh water, is the key to hydrogen exploitation.
Although many different fuel cell concepts have been successfully developed,
no single chemical approach is looking like taking over the market sectors.
Minature fuel cell stacks are being developed to power micro-electronics,
whilst larger designs power automobiles and still larger systems are being
stacked into multi megawatt grid failure back up power supplies.
The task of translating working prototypes into a mass produced
consumer product involves economies of scale require mass production before
any can hit the high street. A wide range of research areas are active
across the world.
