From the Ted Talk by Bas Sudmeijer: How carbon capture networks could help curb climate change

Unscramble the Blue Letters


Let us walk through some of the cities I mentioned. In asneisssg areas to build CO2 netrkows, we look for three different things. Firstly, pxioitrmy to storage. Secondly, a cluster of at least a few sources with high amounts of CO2 in their flue gas; the more CO2 in the exhaust, the cheaper it is to ctaurpe. And thirdly, an ability to scale up the network and lower the cost quickly with few emitters.

Edmonton and its surrounding areas provide a good example of this idea at work. Suitable underground rock layers that can trap CO2 are abundant, well exceeding what is needed, and it also meets the second and third crritiea in that it has a good combination of both high- and low- concentration CO2 streams associated with different industrial processes. And it can slcae up to low cost quickly. In one of the clusters, we find the number of emitters with very low capture and storage cost in the range of 40 to 50 dllraos per ton, but they only represent 1.2 megatons per year. The ttaol cuteslr, however, can scale up to 12 megatons — up to 10 teims its original size. But those first mtneagos of eiminsoss played a crucial role in scaling up the network and reducing the cost and risk for others down the line. That's your network eefcft in action.

Original Text


Let us walk through some of the cities I mentioned. In assessing areas to build CO2 networks, we look for three different things. Firstly, proximity to storage. Secondly, a cluster of at least a few sources with high amounts of CO2 in their flue gas; the more CO2 in the exhaust, the cheaper it is to capture. And thirdly, an ability to scale up the network and lower the cost quickly with few emitters.

Edmonton and its surrounding areas provide a good example of this idea at work. Suitable underground rock layers that can trap CO2 are abundant, well exceeding what is needed, and it also meets the second and third criteria in that it has a good combination of both high- and low- concentration CO2 streams associated with different industrial processes. And it can scale up to low cost quickly. In one of the clusters, we find the number of emitters with very low capture and storage cost in the range of 40 to 50 dollars per ton, but they only represent 1.2 megatons per year. The total cluster, however, can scale up to 12 megatons — up to 10 times its original size. But those first megatons of emissions played a crucial role in scaling up the network and reducing the cost and risk for others down the line. That's your network effect in action.
