Filtering and splitting CO2 from the atmosphere
Due to their enormous space and water requirements, plants are unsuitable for the necessary reduction of the CO2 content in the atmosphere. There is no room for 37 million km² of growing forest.
One process is standard in chemistry lessons: split H2O into H and O with electrolysis and the reverse process, the oxyhydrogen gas explosion. C can also be burned with O2 to CO2 or split again into C and O2. In the compound are 395.5 kJ/mol or 8.989 kj/kg or 2,5 kWh/kg.
Such fission processes always have an efficiency which we assume here to be 60%. That would be 4.16 kWh per kg CO2. But before it can be cracked, the CO2 must be acquired.
418 ppm is currently the volume fraction of CO2 in the atmosphere. The weight proportion is higher in the ratio 29:44. In one cubic metre of warm air, there are 0.76 g CO2. In 1,314 m³ of air there is 1 kg CO2. CO2 is chemically bound in CO2 filters. When the filter is full, this chemical bond must be broken down again.
Efficiencies can be slightly better or worse, a range of 5 to 6 kWh for 1 kg CO2 should be realistic.
|-250% CO2 emission until 350 ppm are reached again|
|Less CO2 emission is much too little, even zero emission is insufficient. Only a planet renovation with large-scale CO2 filtering and splitting from the atmosphere will help.|
|Climate change: Please do not panic|
|With “irreversible” and “last chance, then it's too late” the impression of a hopeless situation is created, which leads to senseless panic reactions or apathy.|
|390 PWh/year electricity for CO2 from the atmosphere|
|Reduce the CO2 content with Power to Carbon, generate fuels with Power to Liquid and use CO2 for indoor plant cultivation to replace large-scale agriculture.|
|Carbon fiber becomes standard material for construction|
|If we filter the 33.1 Gt CO2 emission of 2019 from the atmosphere and split it into C and O, we get 9 billion tons of carbon. What to do with it?|
