Carbon Capture Utilization is such an important topic, but it has always been hard for me to get into it because I think it is a fairly complex. This was a great overview to start to understand to dig into this topic.
Good information. I didn't know this existed, but based on this information alone, I wonder if there is any long term downside to storing excess amounts of carbon under the earth's surface. Saying it mimics nature may be too 'simple'. How certain are we there are no long term side effects we are not yet aware of? What if we run out of space to store it?
This technology is certainly the future of our planet. Similar tech has been implemented on the smaller scale in the past, and I am honestly shocked that it has not developed more rapidly in our generation that is so concerned with the environment. One reason may be the discrepancy between anthropogenic (human-caused) climate change and natural climate change (as evidenced by geological and anthropological research). It is possible that we are experiencing both forms simultaneously, however the extent of the change is so rapid and extreme that there is overwhelming scientific evidence in favour of anthropogenic climate change. Therefore, don't we have a responsibility to clean up the mess we have caused? Technology such as CCU is the key.
Interesting video. My one concern with many of the CCU technologies listed is that they may not permanently store/capture the CO2. Especially for fuels, as soon as you burn the fuel it would release the same CO2 back into the atmosphere. Granted, this helps reduce emissions from burning fossil fuels but it doesn't reduce the total CO2 in the air today. Some of the other methods such as storing it in concrete seem more useful from a climate change perspective since concrete has a usable life of 10-20 years, and even then it may still store the CO2 if the concrete is recycled into new concrete or buried. I wonder what the current cost per tonne is to capture carbon from the air (not just from factories) and when that is expected to be profitable based on current carbon credit pricing in the world. How much does the technology need to improve (or how much worse does climate change need to get) before this is an economically viable business model of selling captured carbon credits?
