Can we re­move green­house gases from the at­mos­phere?

BBC Earth (Asia) - - Science -

Re­mov­ing car­bon diox­ide (CO2) from the at­mos­phere is tricky. Some new tech­nolo­gies use chem­i­cal fil­ters to ex­tract CO2 from the air, but come with a hefty price tag. A more promis­ing method re­lies on plants’ nat­u­ral abil­ity to ab­sorb am­bi­ent CO2 as they grow, trans­form­ing it into biomass. Plant­ing trees or crops there­fore re­sults in a net re­moval of CO2 from the air. Tak­ing things one step fur­ther, this plant mat­ter can be burned in­side spe­cially adapted power sta­tions that pro­duce en­ergy while cap­tur­ing the CO2 emit­ted and bury­ing it un­der­ground. This tech­nol­ogy is, how­ever, still un­der­go­ing de­vel­op­ment.
