Optimistically [1] 200 g can capture 250 kg carbon dioxide per year, at the expense of heating the material almost 28,000 times from ambient to 60°C. And that still leaves you with 139 m³ of carbon dioxide gas, what do you do with that?
[1] 2.05 mmol/g at half capacity equals 45 mg/g per cycle, and ignoring heating and cooling times one can fit 27,976.6 cycles into a year. Overall that is 1.262 kg/g/y.
According to studies about batteries we should have electric planes since 2010 and we should be able to recharge any battery instantly regardless of their size. Ah and these batteries would be very cheap too
And that's if:
- the study can be replicated
- the study wasn't altered to boost publishing metrics
Remember super conductivity at room temperature from a few months back ?
My guess is that it means that the material can be reused by capturing/releasing/sequestering multiple times, and that number reflects how much C02 it can capture given how many cycles can be completed in one year.
