Here is the link to the study.
The researchers, from the University of Cambridge, say their solar-powered reactor could be used to make fuel to power cars and planes, or the many chemicals and pharmaceuticals products we rely on. It could also be used to generate fuel in remote or off-grid locations.
Unlike most carbon capture technologies, the reactor developed by the Cambridge researchers does not require fossil-fuel-based power, or the transport and storage of carbon dioxide, but instead converts atmospheric CO2 into something useful using sunlight. The results are reported in the journal Nature Energy.
Carbon Capture and Storage (CCS) has been touted as a possible solution to the climate crisis, and has recently received £22bn in funding from the UK government. However, CCS is energy-intensive and there are concerns about the long-term safety of storing pressurised CO2 deep underground, although safety studies are currently being carried out.
A tree?
No, tress die and when they rot they release the carbon. You cannot plant enough trees to stop climate change unless you wipe most of humanity off the planet at the same time. We must remove the carbon we introduced into the cycle when we started using fossil fuels.
This is why carbon sequestration is important to pursue.
biochar
You charcoal all trees and brush and put it back into the soil. Helps with water retention and promotes healthy soil. You can put it in cattle feed and reduce methane production. Plus, all that carbon is stable for hundreds of years. I have a small cone pit where I do small batches. My tomatoes and flowers seem to like it.
