Climate change as observed by the contemporary global warming and its impacts on Earth's weather patterns is caused by emission of greenhouse gases (GHG), mostly carbon dioxide (CO2) and methane (CH4). Burning fossil fuels for energy use creates most of these emissions, but also by agriculture, steelmaking, cement production, forest loss and volcanic activities are additional sources. Accelerated by dramatically risen carbon emissions over the past several decades it’s crucial to deploy as many clean energy sources, e.g. H2, and technologies as possible to avoid the worst of climate change. To tackle the human factor that’s where Carbon Capture and Storage/Sequestration (CCS) comes in. This technology allows to separate carbon dioxide from produced emissions before released into the atmosphere, providing a long-term solution to protect our atmosphere from an excess of carbon dioxide and hence, mitigating the effects of climate change.

CCS Modeling

Depending on the CCS objectives and project targets the CO2 is either stored in deep geological formations, saline aquifers or in depleted oil/gas fields. State-of-the-art reservoir simulators have been deployed to control the CO2 injection and predict reservoir pressures as well as chemical effects like carbonization for the long-term storage over centuries or millennia. Geomechanics play an important role managing caprock and well integrity safeguarding the submarine or underground storage security to monitor and mitigate the residual risk of some CO2 might leak back into the atmosphere.
