The production of bioenergy with carbon capture and sequestration is considered a form of carbon dioxide removal (CDR). The process begins by growing biomass, burning it to create energy and finally capturing and sequestering the carbon dioxide created in the process. Negative CO2 emissions are generated by combining bio-energy production [biomass fuel power stations, pulp…
Ocean fertilization is an untested carbon dioxide sequestration (CDR) technique that involves dissolving nitrates or iron into the water which will encourage an increase in carbon uptake by phytoplankton. After the plankton blooms, it dies and then sinks to the ocean floor where the carbon will be stored as sedimentary rock. BENEFITS CHALLENGES Relatively safe…
Ambient air capture, a form of carbon dioxide sequestration (CDR), involves building large machines that can remove carbon dioxide directly from the ambient air so that the captured CO2 can be stored elsewhere. The three steps of the air capture process are: Contacting the air Absorption or adsorption on a sorbent Recovery of the sorbent see also:…
Afforestation is the process of planting trees, or sowing seeds, in a barren land devoid of any trees to create a forest. The term should not be confused with reforestation, which is the process of specifically planting native trees into a forest that has decreasing numbers of trees. The increased number of trees helps to…
