geoengineering explained: the benefits and challenges of bioenergy with carbon capture and sequestration

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 … Continue reading geoengineering explained: the benefits and challenges of bioenergy with carbon capture and sequestration

geoengineering explained: the benefits and challenges of ocean fertilization

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 … Continue reading geoengineering explained: the benefits and challenges of ocean fertilization

geoengineering explained: the advantages and disadvantages of ambient air capture

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     … Continue reading geoengineering explained: the advantages and disadvantages of ambient air capture

geoengineering explained: the benefits and challenges of afforestation

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 … Continue reading geoengineering explained: the benefits and challenges of afforestation
