fuel
cells for battery replacement and backup power systems are niche markets in which price and effi- ciency are relatively unimportant. sales in this mar- ket will drive the technology forward towards the point at which
fuel
cells will become economically viable to introduce into the
energy
sector. •
hydrogen
electrolysers/
fuel
cells connected directly to wind turbines are a convenient way to balance out local fluctuations in the availability of wind power. • the development of
fuel
cells and a
hydrogen
economy will provide new market opportunities and new jobs in denmark as well as elsewhere. • present knowledge indicates that
hydrogen
as an
energy
carrier will involve little environmental risk. figure 1 illustrates how

.system. barriers a
hydrogen
-based society will require fundamental breakthroughs in both basic science and technology. there is still a considerable performance gap be- tween what today’s technologies can deliver and what a market-driven
hydrogen
economy will need. most studies agree that key
hydrogen
technologies are still too inefficient and too expensive to meet our
energy
demands in the near future. most importantly: • more efficient and cheaper ways to make
hydrogen
must be developed. • better storage systems for
hydrogen
in the transport sector are critically important. •
fuel
cell prices must fall, and their operating lifetime must be increased. • an adequate
hydrogen
distribution infrastructure is a prerequisite for the introduction of
fuel
cell vehi- cles on a large scale
hydrogen
production most
hydrogen
produced today is used in the chemi- cal industry. the dominant method of production is steam reforming of natural gas. new large-scale projects have been launched in california and abu dhabi and there are advanced plans for the north sea with
hydrogen
fuel
led power plants combined with carbon capture and storage by ‘decarbonising’ natural gas. this ‘decarbonisation’ technique separates the
hydrogen
and captures the carbon from the fossil
fuel
(in the form of co 2 ). the clean
hydrogen
is then burnt in a specially modified gas turbine to produce clean electricity and the co 2 is captured and stored securely deep underground in depleted oil and gas/oil fields or natural saline formations. alternative
hydrogen
production methods include gasification and reforming of other
fuel
s, electroly- sis, and biological methods. biogas can be reformed
