Did you know that CCS can reduce your CO2 fees?
Taxes and fees on emissions are increasing and CCS is evaluated as an alternative to power from shore or expensive fees in the oil and gas sector.
1. Why should anyone store CO2?
Carbon capture and storage (CCS) is a method of preventing CO2 from reaching the atmosphere. It is an important strategy for achieving global emissions reduction targets and transitioning to a more sustainable and low-carbon economy.
2. How is CO2 capture and storage (CCS) done?
CCS involves capturing CO2 before it is released into the atmosphere, compressing it, and transporting it either via vessels or pipelines to be stored underground.
3. Is CO2 storage really sustainable?
It depends mainly on three things;
- Where you get your CO2 from
- The amount of CO2 generated in the CCS- process itself
- How it is done; – preventing a leakage is a must
You need to look at the emissions along the entire value chain to see if the process is sustainable. For operations like large old coal fired powerplants, is it more sustainable to shut down all together.
For some industrial emissions, like cement, steel etc., there are limited opportunities to reduce the CO2 emissions. For these industries CO2 storage makes sense in terms of sustainability.
4. How can our experience with CO2 storage benefit operators?
Our team is highly experienced and skilled in the process of qualifying a subsurface CO2 storage site. Our team assists clients on:
- Documentation of the integrity of the storage complex
- Assuring that the storage site has the required integrity, size, efficiency etc.
- Addressing the storage formation and the overburden using subsurface evaluations such as pressure evaluations, flow analysis, geomechanical modelling, network and fluid phase modelling etc.
- Interpreting data and building static and dynamic models, to predict the behavior of a given storage site under the operational conditions (injecting and storing CO2).
- Assessment of well injection and storage rates, flow assurance and development solutions.
- CO2 well integrity both for new and old (P&A) wells
- Planning, operations and executing of drilling of storage wells
- CO2 transport, vessel design and transport evalution.
5. How long does it take?
Maturing a storage site can take years. For some sites one needs to acquire new data through a well or acquiring new geophysical or geochemical data. The operations themselves typically take from 5-20 years depending on the size of the storage site. And even after operations are seized you need to monitor the site for tens of years.
