PROCEDURE

CAPTURE – CARBON SEQUESTRATION

Process of removing carbon from the atmosphere and depositing it in a reservoir

Also referred to as carbon dioxide removal, which is a form of geoengineering.

Proposed as a way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels.

Refers to large-scale, permanent artificial capture and sequestration of industrially produced CO2 using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks.

CONVERSION OF CO2 BY PYROCOCCUS FURIOSUS BACTERIA Chemosynthetic bacteria such as Pyrococcus

Furiosus,  don’t need sunlight to convert carbon dioxide into organic compounds, but do so in temperatures exceeding 800°F on the pitch-black sea floor.

By tweaking the genetic structure of P. Furiosus, researchers succeeded in using it to convert carbon dioxide, at much lower temperatures, into 3-hydroxypropionic acid, a common industrial chemical.

The fuel thus obtained would only release the amount of carbon used to make the fuel and no additional amounts would be created

PYROCOCCUS FURIOSUS BACTERIA

HYDROCARBON FUEL FROM CO2 THROUGH PHOTOCATALYSIS Direct conversion of CO2 and water into

hydrocarbon fuels using sunlight the CO2 is collected and passed

through a photo catalytic sieve; in the sieve the CO2 is exposed to sunlight and with the addition of water it is converted back into a hydrocarbon fuel.

the photo catalytic reduction of CO2 with H2 and or H2O is done with nitrogen doped titania as catalyst.

PHOTOREDUCTION OF CO2

CONVERSION OF CO2 INTO METHANOLmethanol (CH30H) can be turned into a form of bio-

diesel fuel and burned in engines. This technique uses a thermal process to coat

copper oxide (CuO) nanowires with another form of copper oxide (Cu2O) and submerging them in a solution rich in carbon dioxide.

The CuO-Cu2O hybrid nanorod arrays are then subjected to sunlight – or simulated sunlight in the lab – to trigger a chemical reaction and produce liquid methanol.

The experiments generate methanol with 95 percent electrochemical efficiency and avoided the excess energy input, also known as overpotential, of other methods.
