“…Following the success of the initial CarbFix project in Hellisheidi, the project was upscaled starting in 2014 with a stepwise increase in amount of gases injected subsequently (e.g. Gunnarsson et al, 2018;Sigfusson et al, 2018). The acid gases (CO2 and H2S) are captured directly from the power plant exhaust stream by its dissolution into pure water (condensed steam from the power plant turbines), in a scrubbing tower.…”

“…The first pilot injections took place at Hellisheidi in South West Iceland in 2012; 175 tons of pure CO 2 were dissolved and injected at about 500 meters depth and about 35 • C (Matter et al, 2016). Following the success of the pilot injections, the project was scaled up to industrial-scale in June 2014 as a part of the CarbFix-SulFix project, with injection of 65% CO 2 -35% H 2 S gas mixture at about 800 m depth and about 230 • C. The injection is now an integral part of the operations at the Hellisheidi power plant (Sigfusson et al, 2018).…”

In recent years Direct Air Capture (DAC) has established itself as a promising approach to atmospheric Carbon Dioxide Removal (CDR) also referred to as Negative Emissions. However, due to the amounts likely needed to be removed CDR technologies like DAC will only become climate relevant if they rapidly reach gigaton scale, around the middle of this century. Here we give a brief insight into DAC and in particular, the modular low temperature DAC technology developed by Climeworks of Switzerland. We discuss potential co benefits, in particular in relation to the Sustainable Development Goals (SDGs) of the United Nations and conclude by suggesting some policy approaches on how a climate relevant scale could be achieved in time.

“…As a result, the geothermal fluid resource in the reservoir is gradually diluted and the field pressure is reduced over time, affecting well productivity. For example, at the Hellisheiði field in Iceland the mass flow of CO 2 has decreased from 120 tonnes/day to 100 tonnes/day since the early 2014 [14].…”

The non-condensable gases in most geothermal resources include CO2 and smaller amounts of other gases. Currently, the worldwide geothermal power is a small sector within the energy industry, and CO2 emissions related to the utilisation of geothermal resources are consequently small. In some countries, however, geothermal energy production contributes significantly to their energy budget and their CO2 emissions are relatively significant. SUCCEED is a targeted innovation and research project which aims to investigate the reinjection of CO2 produced at geothermal power production sites and develop, test and demonstrate at field scale innovative measurement, monitoring and verification (MMV) technologies that can be used in most CO2 geological storage projects. The project is carried out at two operating geothermal energy production sites, the Kızıldere geothermal field in Turkey and the CarbFix project site at the Hellisheiði geothermal field. Together with a brief description of the seismic monitoring technologies proposed in the project, this paper presents the details of the two field sites and the progress made in installing and testing of the surface fibre-optic cables at the Hellisheiði geothermal field in Iceland.
