An unconventional mélange of algae, eucalyptus and bioenergy with carbon capture and storage seems to be a quirky ecological recipe. But, researchers from Cornell College, Duke College, and the College of Hawaii at Hilo have an concept that could use that recipe to assistance electricity and provide food items protein to significant locations of the entire world — and at the same time take out carbon dioxide from Earth’s atmosphere.

“Algae may perhaps be the important to unlocking an significant adverse-emissions engineering to battle local weather change,” explained Charles Greene, Cornell professor of Earth and Atmospheric Sciences and a co-author of new research revealed in Earth’s Long term, by the American Geophysical Union.

“Combining two systems — bio-electrical power with carbon capture and storage, and microalgae manufacturing — may possibly appear to be like an odd couple, but it could offer ample scientific synergy to assist address planet hunger and at the very same time lower the degree of greenhouse gases that are shifting our local climate method,” Greene reported.

Centered on an concept very first conceptualized by co-writer Ian Archibald of Cinglas Ltd., Chester, England, the researchers phone the new integrated system ABECCS, or algae bioenergy with carbon capture and storage. The procedure can act as a carbon dioxide sink even though also making foodstuff and energy. For case in point, a 7,000-acre ABECCS facility can yield as a lot protein as soybeans created on the identical land footprint, although concurrently generating 17 million kilowatt several hours of electricity and sequestering 30,000 tons of carbon dioxide for each calendar year.

The ABECCS system’s financial viability depends on the worth of the nutritional items staying produced and the rate of carbon. Even with no a cost on carbon, microalgae generation — in a fish-farming, aquacultural perception — is commercially viable right now if the algae are priced as a fishmeal substitution in aquafeeds.

“In the long term, as the value of carbon improves, ABECCS has the opportunity to reduce carbon dioxide in the environment in an environmentally sustainable and successful way,” claimed Greene, who is a fellow at Cornell’s Atkinson Heart for a Sustainable Future.
