Saving Iceland

Contrary to popular belief, hydroelectric power can seriously damage the climate. Proposed changes to the way countries’ climate budgets are calculated aim to take greenhouse gas emissions from hydropower reservoirs into account, but some experts worry that they will not go far enough.

The green image of hydro power as a benign alternative to fossil fuels is false, says Éric Duchemin, a consultant for the Intergovernmental Panel on Climate Change (IPCC). “Everyone thinks hydro is very clean, but this is not the case,” he says.

Hydroelectric dams produce significant amounts of carbon dioxide and methane, and in some cases produce more of these greenhouse gases than power plants running on fossil fuels. Carbon emissions vary from dam to dam, says Philip Fearnside from Brazil’s National Institute for Research in the Amazon in Manaus. “But we do know that there are enough emissions to worry about.”

So writes the poet and protester Elísabet Jökulsdóttir, and sitting in the board room of Landsvirkjun at a table long enough to hold a state banquet, it is hard to disagree with who is responsible for Kárahnjúkar. The walls of the ‘president’s floor’ have portraits of the men who in former times have managed the national power company. Read More

It is now two years since the government gave the approvals that made way for the creation of a huge hydroelectric scheme in the Central Highlands at Kárahnjúkar. This paved the way for a subsequent deal with Alcoa for the building of an aluminium smelter in the coastal town of Reyðarfjörður.

WHAT DOES THE SCHEME INVOLVE?

The Kárahnjúkar project will consist of nine dams, three reservoirs, seven channels and sixteen tunnels. It will divert two large rivers, the Jökulsá á brú and Jökulsá í Fljótsdal, and several smaller rivers to the north of the Vatnajökull glacier, the largest glacier in Europe. The main dam will be highest rockfill dam in Europe, 190 metres high, 800 metres long and 600 metres wide at its base. This main dam will create a huge reservoir, to be called Hálslón, which will flood a wilderness area of 57 sq. km. 70 km of tunnels will carry water to an underground powerhouse, which will have a 690 megawatts capacity.

‘Damned Nation’ is very good on the spiel behind the Karahnjukar project and Alcoa.

Costing over $1 billion, the Karahnjukar hydroelectric dam in Iceland is a hugely controversial project. Mark Lynas journeyed to the blasting face, hoping to work out for himself whether this industrial elephant is green or brilliant-white.
