Advantages from Combining CCS with Geothermal Energy

Abstract Carbon capture and storage (CCS) technology is one important option to reduce CO 2 emissions, however social, political and mainly economic barriers limit its implementation. A combination of CCS-geothermal technologies can contribute to achieve faster this reduction and to decrease costs by sharing injection wells, using CO 2 instead of water as heat transfer fluid, thereby lowering water consumption and saving pump costs. It can also change public perception towards CCS. This technology is currently in mature level, allowing to store CO 2 in a safe way. Moreover all knowledge acquired on CO 2 storage and monitoring can be also used for geothermal energy.
