Technology from University of Bergen may generate a new energy source – VG 20th May

Researchers from Bergen have developed a new method for natural gas extraction by exploiting. The US Department of Energy has invested 10MILL dollar, and ConocoPhillips is industrial partner. Now the method shows promising results in a comprihensive field trial in the North Slope region of Alaska.The norwegian national newspaper VG has interviewed the professor and inventor Bjørn Kvamme

The global amount of energy in the form of hydrate may amount to more than double the energy reserves in coal, oil and gas worldwide. The problem has been extracting the hydrates from the deep ocean floor.Gas hydrate appears as ice-like solids consisting of water and gas; which in nature mostly is methane. Natural occurrences are found in conditions at high pressure and low temperature; i.e. in arctic tundra and beneath the deep ocean floors.

The new method developed by researchers at the University of Bergen is patented and on its way to commercial realization with guidance from BTO, is to expose the natural gas hydrate to CO2. CO2 hydrate is thermodynamically more stable than natural gas hydrate and it has been calculated and experimentally shown that CO2 hydrate is formed while methane gas is released. Thus, a win-win situation of simultaneous storage of CO2 with spontaneous release of natural gas is the result; with no net production of water and no macroscopic melting of the hydrate, keeping the rock formation intact.
