#carbondrawdown is going to be essential - yes, we need to stop further emissions, but we also need to deal with centuries of emissions. Large scale deployment of #cryogenicenergystorage generating dry ice serve as a primary means of carbon collection. What already is a good long lasting option for large scale #renewable #energy storage could serve as carbon scrubbers almost for free, just by adding a mechanism to extract dry ice instead of filtering out CO2. https://en.wikipedia.org/wiki/Cryogenic_energy_storage
