Landsvirkjun, the national power company of Iceland, on June 28 announced it intends to capture and reinject carbon dioxide (CO₂) from Þeistareykir (Theistareykir) Geothermal Station, and at the same time reduce CO₂ emissions from Krafla Power Station through enhanced well management efforts at that site. Construction of the project, called Koldís, is expected to begin next year, and the project should be fully operational by 2025.

Landsvirkjun wants its operations to be carbon neutral in 2025, and already has progressed toward that goal, reducing the group’s carbon footprint by 61% since 2008. A major part of its strategy is to significantly reduce emissions from geothermal power generation, as the vast majority of the company’s greenhouse gas emissions are generated by geothermal energy. Landsvirkjun expects the Koldís project will capture almost all CO₂ and hydrogen sulfide from the two-unit, 90-MW Theistareykir power station (Figure 1), and return it to the ground for storage, from 2025 onward.
