Iceland experiment to turn carbon dioxide into limestone

Publish date: September 1, 2011

A new experiment will begin in September at Hellisheidi in south west Iceland, near Reykjavik Energy’s geothermal power stations. It will test the viability of storing carbon dioxide underground by artificially creating seams of limestone.

The purpose is to pump CO2 into a basalt rock, where it would be captured by forming limestone. The technique involves forming so-called seltzer water which reacts with calcium in porous basalt and forces the dissolved CO2 into harmless calcium carbonate, more commonly known as limestone. It means there would be no risk of CO2 leakage. As basalt is a very common rock in the Earth’s crust, the technique could be carried out on a massive scale if proved effective.

 

The first stage of the CarbFix experiment (an American-Icelandic joint venture) will last six months to one year.

The role of CCS in Germany’s climate toolbox: Bellona Deutschland’s statement in the Association Hearing

After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.
