A new way to remove CO2 from the atmosphere
absorb carbon dioxide
natural way
rock
soil
plant
not enough
sea water
Artificial
like synthetic forest
dissolve in water
Air Capture Contactor
composition
fill packing material
fans bubble up
reaction
Separation of carbon dioxide and liquid
by strong-binding molecule
need deeper
In order to get more CO2
cost more energy
very wide
big surface
structure
Big surface
Very thin
solid material
unique design
need recyclable
large scale
by energy
release high-purity CO2
easy liquify
easy transport
easy to use
fuel
Chemical material
the cost
A powerplant
coal
more CO2 than you capture
etc
expensive CO2
convert to fuel
50 dollar per gallon
too expensive
Not feasible
Company
way to reduce the cost
Carbon Engineering (in Canada)
burn cheap and enough gas
provide heat
They have a cleaver way
capture
CO2 that burn the natural gas made
1 more item...
CO2 in air
1 more item...
Separate in liquid form
Climeworks
use heat from earth
excessive steam from industrial process
Reduce pollution
Geothermal
Global Thermostat
heat required
speed the heat through
fast way
to release and produce
have compact design
solid material for capture
Make carbon into a marketable product
liquid fuel
plastic
synthetic gravel
natural forest
Amazon Rain Forest
capture 1.6 billion tons of CO2 each year
=25% of annual emissions in the US
5.5 million km²
Synthetic Forest
Advantage
size
500 times smaller than Amazon Rain Forest
to capture the same CO2
build on arable land
no competition
farmland
food
Manufactured direct air capture plant
reflection
new technology
energy efficiently
low-energy carbon
improve farming
net-zero emission of carbon
not the solution
not enough
regulation
taxes
subsidy
