A cleaner planet, where global warming is under
control and the world's energy needs are met -- that's the vision for the year
2030 that Greenland, Iceland, Norway, Sweden and Finland are pursuing.
Iceland and Greenland plan to do this through the development of hydrogen fuel,
"the new oil" of the 21st century.
To produce hydrogen fuel, all you need is water and a basic source of power
to help break water down into its elements, hydrogen and oxygen. Hydrogen, when
compressed, makes an efficient fuel: it can be used with fuel cells to power
vehicles; it can provide electricity and heat; and it can turn renewable
energies, such as solar, geothermal, hydro-electric or wind power, into a stored
energy source.
This all sounds very attractive to Johan Lund Olsen, Greenland's minister for
industry, energy, agriculture and labour, who sees a bright future ahead for
hydrogen and hydrogen production.
"We want to bring down our dependence on oil," Lund says.
Some day, larger versions of the "pill" that Lund is holding may store and
supply power to fuel cells in vehicles, ships, railways, aircraft, cell phones
and computers, replacing conventional batteries and fuels.
Fuel cells have been around for a long time, but storing hydrogen to power them
has always been a problem. But Lund's pill, recently developed in Denmark,
contains an amount of energy equal to that found in a regular 50-litre gas tank.
Now, Greenland is looking at a switch to hydrogen fuel because it's locally
available in great quantities.
That's because hydrogen can be produced on Greenland's ice cap, where there's
huge hydroelectric potential, or by using excess energy from the hydro-electric
plant in Kangerluarsunnguaq near Nuuk -- and there's no lack of water in
Greenland either.
Because Greenland can't use all its energy locally, Lund says. So "some can be
used to make hydrogen. It's very simple."
Switching to hydrogen will also be good for reducing greenhouse gases, which
contribute to global warming, because, unlike fossil fuels such as oil, coal or
gas, hydrogen fuel is not burned to produce power. It uses a simple
electro-chemical reaction, which allows a fuel cell to operate quietly,
efficiently and virtually pollution-free.
Iceland already has two non-polluting hydrogen buses in its Ecological City
Transport System, which produce puffs of steam instead of exhaust. Lund says
Greenland can, moreover, look towards becoming a major hydrogen producer.
The European Union is putting EU 300-mm (about half a billion dollars) into
developing "a hydrogen economy," and, by 2030, the Nordic countries want
hydrogen to provide 18 % of their energy needs. The Nordic Council, the
parliamentary co-operation body for the Nordic countries, is pumping another
7-mm Danish kroner (about $ 1.5 mm) into Arctic research.
Greenland is positioning itself to be in the middle of the development of this
new economy, Lund says, by constructing a third hydro-electric project, and
smaller hydro plants near Sisimiut and Paamiut.
"We have a potential to make our own energy, up to 13,000 kWh a year near
cities," Lund says. But he says producing hydrogen fuel and developing
hydro-electric power is just "part of the puzzle" of making Greenland
self-sufficient in energy.
Wind and solar energy projects in southern Greenland, in partnership with
Iceland, are also in the plan. Although these projects are relatively
inexpensive, the Nordic countries, through their membership in the Nordic
Council, contribute money for research and development and encourage cooperation
between members. The idea is to promote an energy market without borders, which
will have a high degree of security and be environmentally friendly.
Greenland is also working with Iceland to locate possible thermal energy
sources. So far, 200 potential "hot spots" have been found in Greenland. Working
with Iceland is natural, because Iceland is a world leader in developing
geo-thermal energy, which flows under the many volcanoes that dot the island.
Until the 1930s, Icelanders used this ample source of natural hot water mainly
for laundry and bathing.
Iceland now taps the underground hot water reserves to produce steam. This steam
pushes turbines that make electricity. As steam from this hot water is busy
making electricity, it also runs through pipes that warm nearly all of Iceland's
homes, and heats the greenhouses that provide 80 % of the tomatoes and cucumbers
that Icelanders eat.
Greenland also mounted public campaigns for energy conservation and reducing
greenhouse gas emissions.
"We can see the consequences of climate change," Lund says. "The hunters can see
and touch it, so it makes people very aware. There is a need to take action
right now and start up the whole process as quick as possible."
