Just to tie off the sequester discussion.
Valid point re feedstock volume and reliability.
The alternative to a nearby single C02 source (gasification, coal-powered power plant) is a collector network; a first mile tie-up from source to network, and a last mile tie-up from network to injection facility. Refurbish and reuse the existing collection network in spent fields, and 1) capital costs come down quite a bit, 2) proximity favours CO2 from a local basin returning to the same basin, and 3) CO2 emission has economic incentive to feed into the network versus simply vent. Collector networks become environmental ‘assets’ enabling physical tracking of CO2 processing, digital tracking via blockchain, fully transparent reporting of ‘net’ versus ‘gross’ environmental CO2 emission, and robust carbon-trading. If both source and injection facility are in the same province - it is also a much easier political ‘sell’.
There are really ‘two’ carbon cost recovery prices. A high cost to extract diluted carbon from the atmosphere (energy, diluted concentration, minimum scale, etc.), and a much lower cost to extract carbon from a much more concentrated and reliable source (injector facility cost structure resembling a refinery). Pay more to dispose via venting, or less to dispose via the collector facility (plus a cost of $X per km transported). Then add to it that the injection facility is both a monopoly AND a clean air refinery, and that the existing collection facilities of o/g producing provinces gives them a competitive advantage.
Sequestment is ‘social enterprise’ investing; and very strongly resonates with both Gen Z (born >1995) and Millennials (born 1981-1995). Furthermore, recent surveys indicate that on average ‘consumers would spend 17% more for products that came with social or environmental benefits; 58% of responders also wanted to understand the impact they’re having when they buy a product linked to a social cause' (WEconomy; Keilburger, Branson, Keilburger, p129). Us ‘older’ generations, arguing against carbon-tax because it will both disrupt and raise prices, just don’t get it. Yes, we may win battles in the near-term, but we aren’t going to stop the flow of the river.
Hence new attitudes, and new approaches.
