A significant milestone in reducing greenhouse gas emissions was celebrated yesterday as&nbsp;Jóhann Páll Jóhannsson, Minister for the Environment, Energy and Climate, formally opened the&nbsp;Steingerður air capture facility&nbsp;at ON Power’s Hellisheiði Geothermal Power Plant.The design and construction of Steingerður is a key component of the&nbsp;Silfurberg project, an innovation initiative supported by the&nbsp;European Union’s Innovation Fund. Together with the existing air capture station, Steingerður will have the capacity to capture nearly all&nbsp;carbon dioxide (CO₂)&nbsp;and&nbsp;hydrogen sulfide (H₂S)&nbsp;emissions from Hellisheiði.The opening of Steingerður marks a turning point, making&nbsp;Hellisheiði one of the first geothermal plants in the world to become nearly carbon neutral.&nbsp;A Landmark Climate ProjectThe&nbsp;Silfurberg project, led by&nbsp;Carbfix&nbsp;and&nbsp;ON Power&nbsp;(subsidiaries of&nbsp;Orkuveitan), aims to demonstrate CO₂ capture and permanent underground storage on a larger scale than before. The project received&nbsp;€3.87 million in funding&nbsp;from the EU Innovation Fund, enabling Carbfix to scale up its technology.With Steingerður, the facility will be able to&nbsp;capture around 30,000 tons of CO₂ annually, which will then be&nbsp;safely and permanently turned into stone&nbsp;using the Carbfix method.&nbsp;A Natural and Proven SolutionCarbfix has been developing its technology at Hellisheiði since 2007 and has created a&nbsp;pioneering solution&nbsp;that transforms CO₂ into rock in less than two years. The method accelerates natural processes that mineralize carbon dioxide and safely stores it in subsurface basalt formations.&nbsp;A Major Contribution to Iceland's Climate GoalsThe Silfurberg project alone is expected to contribute&nbsp;10% of Iceland’s 2030 climate commitments&nbsp;within the energy and industrial sectors not covered by the EU Emissions Trading Scheme (ETS).It aligns well with Iceland’s goal of a&nbsp;55% reduction in emissions by 2030&nbsp;and underscores the growing role of geothermal energy in the global energy transition.
