It sounds a bit like an environmental dream: an industrial plant that sucks CO2 from the air itself (cheaply, too), and converts it into fuel which will be used for cars and planes. However, it's an actual project developed by scientists from Harvard University and Carbon Engineering, a Bill Gates funded company. If the new method is successfully enforced at scale, it may mean a more “optimistic” future for global climate change.
In 2011, specialists calculate that it might cost a minimum of $600 to get rid of a metric ton of CO2 from the atmosphere. The new approach may take away a similar quantity for as very little as $94.
The technique involves 3 major steps: first, outside air gets sucked into an industrial plant “contactor” and exposed to an alkaline liquid. Once the air meets the sturdy base, it turns into water liquid containing CO2. In a plant, it undergoes variety of chemical reactions that then separates the base from the acid — a method usually performed in paper mills. Lastly, CO2 gets combined with hydrogen, and converted into liquid fuels, together with ones that may be used to power cars and planes (meaning that someday, the corporate may manufacture truly carbon-neutral fuels for vehicles).
