Old but NewNew but OldModified Conventional Energy TechnologiesAndBridging Technologies
Modified TechnologiesCarbon Capture and SequestrationBurn coal Capture all CO 2 emissionsSequester CO2 emissions by pumping intoThe groundCavesOil wells The Deep Ocean
Other Methods of Carbon StorageBio-storageGrow stuff and bury itMineral storageMake Limestone
CCS: Does it really work?Pilot Plants in operationQuestions about submerged lifetimeNo long term dataRequires extra energy (25%-40%)Acidify the oceans?Takes too long to grow stuffTakes too long to make limestone and too much energy, even though its exothermicCost?Stay tuned!!
