meaning a high proportion of the c02 touches the surface and is absorbed. steam is then used to wash out the c02 which is processed and stored, ready for local use. this can then start its work over again. three commercial trials are already under way, but this solution is relatively small beer. perhaps one of the best technologies at solving the carbon problem is nature itself. i ve come to brynau wood in south wales, one the last patches of a once enormous ancient woodland. today, a reforestation project is under way. many countries have committed to planting more trees to soak up c02 but my guide gwyn says the mix of trees planted is crucial to success. when there is a mixed amount of tree species within a forest, so the more biodiverse we have in terms of what s above the ground,

so we have a 2 stage process. in the first stage, we blow air through. co2 sticks on the material, they are purified air so air without co2 or with very little co2 leaves the box. when the filter s full, we close the door and start heating. we heat up the collector up to 100 degrees, co2 is released and we take it out. once the filters are cleaned, the carbon capture can start all over again. perhaps one of the best technologies at solving the carbon problem is nature itself. i ve come to brynau wood in south wales, one the last patches of a once enormous ancient woodland. today, a reforestation project is under way.
created in a chemical that absorbs c02. as the air travels through, the tiny holes provide an enormous surface area, meaning a high proportion of the c02 touches the surface and is absorbed. steam is then used to wash out the c02 which is processed and stored, ready for local use. this can then start its work over again. three commercial trials are already under way. commercial trials are already underway. but commercial trials are already under way. but this solution is relatively small beer. perhaps one of the best technologies are solving the carbon problem is nature itself. i ve come to brunei would in south wales, the last patches of a once enormous ancient woodland. today, reforestation process is under way. today, reforestation process is underway. many today, reforestation process is under way. many countries have committed to planting more trees to soak up c02 but my guide quinn says the mix of trees planted is crucial to success.
removal are much cheaper. but i think ultimately looking there as a solution to our large carbon problem is a bit of a mistake. we need it. especially to deal with parts of the carbon economy that are going to be hard to get all the way to zero emissions. but a big study that came out a year ago suggested that just to deal with the hardest to decarbonize sectors, the heaviest industries, the airline fuels, if we wanted to do that through natural solutions, we would have to plant trees two to three times the size of texas and if we wanted to do it using machines, we would have to use half of today s global electricity to power those machines. it s a hugely important part of the puzzle and we should be investing in it and making it cheaper. but we can t let that be a reason to move any more slowly on the decarbonization of the power sector which we know how
