Could artificial trees solve the global warming crisis?

We ’ve known about the effects of climate alteration for 10 now , but the preceding few class ( and even months ) have been in particular divulge . This past year , for instance , we ’ve seenarctic sea frosting levels reach an historic low , while the United States has experienced itsworst wildfire season on record(not to mention all thenew temperature platter ) . In these desperate times we may have to call upon despairing measuring stick , including any number ofproposed geoengineering labor . But as Gaia Vince of BBC Futurerecently place out , the solution may just involve the betterment of an existing “ carbon capture ” technology : The modest tree .

Indeed , plants are nature ’s way of pulling carbon dioxide from the atmosphere . later on , many ecologists have suggested that we simply plant more trees and other leaf . But as Vince notes , there are limits to such design , admit the high demand for farming space .

Instead , Vince points to the work ofKlaus Lackner , director of the Lenfest Center for Sustainable Energy at Columbia University , who has design an hokey tree that take in CO2 from the air using “ leaves ” that are 1,000 prison term more effective than the real thing — but at the same time does not ask photo to sunlight .

Vince write :

The leaves seem like sheets of papery charge plate and are coat in a resin that contains sodium carbonate , which pull carbon copy dioxide out of the air and storehouse it as a hydrogen carbonate ( bake soda ) on the folio . To polish off the carbon dioxide , the leave are rinse in water vapour and can dry out by nature in the wind , soaking up more carbon dioxide .

Lackner calculates that his tree diagram can transfer one metric ton of C dioxide a day . Ten million of these Tree could remove 3.6 billion tonnes of carbon dioxide a class – equivalent to about 10 % of our globose annual carbon dioxide emissions . “ Our total emission could be removed with 100 million trees , ” he articulate , “ whereas we would need 1,000 times that in literal tree diagram to have the same effect . ”

As for what should be done with the lead stores of CO2 , Lackner suggests that it be converted into liquid fuels to king vehicles . And indeed , carbon dioxide make atomic number 6 monoxide and hydrogen when it reacts with water — a solution lie with as syngas on account of its ability to be convert into hydrocarbon fuels like methanol or diesel . Again , Vince writes :

We have the technology to suck carbon copy dioxide out of the air – and keep it out – but whether it is economically practicable is a different inquiry . Lackner says his trees would do the job for around $ 200 per t of off carbon dioxide , dropping to $ 30 a tonne as the project is scale up . At that price – which has been criticised as wildly optimistic ( the American Physical Society ’s most optimistic calculation for direct air capture are $ 600 per tonne of carbon dioxide removed , although the UK ’s Met Office is more lucky ) – it starts to make economical sense for oil color companies who would bear in the area of $ 100 per tonne to employ the gas in enhanced oil convalescence .

As Vince correctly head out , Lackner ’s programme is indeed very expensive . But that said , it is a design — and one that sounds rather refined . In full term of the costs , that will have to be set off against the chance of doing nothing .
