Shashi, Rapid decarbonization will not occur until the cost and convenience of doing are readily available to all. As Elon Musk said, the cure cannot be worse than the disease. Right now, fossil fuels are cheaper and more convenient than the alternatives. Overcoming that is part of the $100 million Carbon Removal XPRIZE. Current technologies are not really sufficient. What is needed is something that can work every day without a lot of fuss and bother on the part of the average citizen. One wild idea is to use something like the solid CO2 absorbents that are deployed on the space station. Create a cartridge that fits in the front of an automobile, about where the radiator is. Then by driving around, CO2 will be removed from the atmosphere. When the cartridge is used up, it is taken out and replaced with a refurbished one. The spent cartridge is collected and sent to a regeneration facility. The refurbished cartridge is recycled. The CO2 that is driven off is sent to a permanent, underground storage site. The average person does little and has essentially no cost, but in driving around, collects CO2 from the atmosphere. The cost has to be borne in some way. That could be highway taxes or a carbon tax, but that is relatively convenient for the average person. Now I don’t know if that idea will really work or not. The point is that some 200 - 250 million cars on the road could be collecting CO2 from the atmosphere with little or no effort on the part of the average person. A way to finance the cost will be needed and a permanent storage facility for underground CO2 storage will also be needed. There are many ways that could come about. Exxon is looking at sending captured CO2 out to the Gulf of Mexico and sequestering it under the ocean floor. In any event, it is those types of ideas and concepts that need to be developed. Otherwise, people will continue to do what is cheaper and more convenient for them.
