It is claimed that regenerative agriculture might sequester around 3 Gt of carbon each year , and that by 2050, biochar production could account for another 1 Gt of carbon annually. In principle the carbon in the soil can stay there and improve its quality, but if the other kinds of captured carbon could be harvested, it might provide a useful potential source of biomass\/fuel. Growing algae on a local pond  could provide energy to replace fossil fuels for local communities, without impacting on arable land.<\/p>\n<p>Since we emit 7 Gt\/year of carbon from fossil fuels, the sum comes out something like (in Gt): 7 &#8211; 3 &#8211; 1 -1 = 2 Gt left to worry about. A cut in fossil fuel use by 50% through biomass curbs that to 1 Gt. Photosynthesis already absorbs around 3 Gt of carbon\/year into oceanic phytoplankton and land-based plants, and if localised algal production cuts emissions from oil by another 1 Gt (assuming that we need 1 Gt less since we have that from algal biomass), the combined scheme is carbon negative by -3 Gt\/year.<\/p>\n<p>Hence in 40 years this would have cut 120 Gt of carbon from the atmosphere, which would reduce the concentration of CO2 by around 50 &#8211; 60 ppm.<\/div>\n<p><a href=\"http:\/\/scitizen.com\/stories\/Future-Energies\/2009\/02\/Thinking-Positive---Carbon-Capture-\/\">See more<\/a><\/p>\n<p>By the way, have you <a href=\"http:\/\/www.oilgae.com\/blog\/feed\/rss.xml\">subscribed to the Oilgae Blog?<\/a>; How about <a href=\"http:\/\/oilgae.com\/mlist\/user\/subscribe.php\">joining the Oilgae mailing list?<\/a>; and <a href=\"http:\/\/www.oilgae.com\/forum\">our forum to discuss on with others<\/a>?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You are at: Oilgae Blog.
