We have been digging huge holes into the country side mining coal.
Now, CO2-levels in the atmosphere have risen so far that we will need to actively remove some CO2 from the atomsphere to stop the earth from overheating.
It's time to fill up those mines again - with coal!
Let's use plants that absorb a lot of CO2 very quickly, pyrolyse them to turn them into biochar, and fill those holes up again!
Unlike some others, this solution does not require specific geology to work.
When we think of hard to abate CO2 emitting sectors, we think of cement factories, steel production, and chemical production. Those seem (to me) too duanting a challenge to jump to from scratch when it comes to CCU. How do you scale and learn and improve from nothing to those large and complex and voluminous CO2 emissions. ? The answer is beer !. It turns out breweries world-wide account of a significant amount of CO2 production from the brewing process. 190 billion liters of beer are produced yearly which at ~4kgCO2 per 100liter yields 8Gt CO2 emission from beer. However, there are breweries of all sizes and micro-breweries typically come in at ~200 000l/yr=8tCO2: a more manageable starting point. The idea would consist of developing a modular and cheap low-tech photo-bio-reactor that can be installed into micro-breweries to capture their CO2 emissions. This would offer the opportunity to learn and improve and the modularity would enable incremental steps towards larger breweries and eventually larger CO2-producing industries.
