An unconventional mélange of algae, eucalyptus and bioenergy with carbon capture and storage appears to be a quirky ecological recipe. But, scientists from Cornell College, Duke College, and the College of Hawaii at Hilo have an strategy that could use that recipe to assist electrical power and present foods protein to huge locations of the globe — and simultaneously remove carbon dioxide from Earth’s environment.

“Algae may possibly be the important to unlocking an essential destructive-emissions technology to battle local climate transform,” explained Charles Greene, Cornell professor of Earth and Atmospheric Sciences and a co-author of new study posted in Earth’s Long run, by the American Geophysical Union.

“Combining two technologies — bio-strength with carbon capture and storage, and microalgae production — might seem to be like an odd pair, but it could provide sufficient scientific synergy to assistance clear up world starvation and at the exact same time minimize the amount of greenhouse gases that are modifying our weather system,” Greene claimed.

Dependent on an thought first conceptualized by co-writer Ian Archibald of Cinglas Ltd., Chester, England, the researchers call the new built-in procedure ABECCS, or algae bioenergy with carbon capture and storage. The program can act as a carbon dioxide sink though also producing food and electricity. For example, a 7,000-acre ABECCS facility can yield as significantly protein as soybeans created on the exact same land footprint, whilst at the same time making 17 million kilowatt hrs of electrical power and sequestering 30,000 tons of carbon dioxide for each calendar year.

The ABECCS system’s financial viability relies upon on the worth of the nutritional merchandise being generated and the price of carbon. Even with out a value on carbon, microalgae output — in a fish-farming, aquacultural sense — is commercially practical nowadays if the algae are priced as a fishmeal replacement in aquafeeds.

“In the future, as the price of carbon raises, ABECCS has the possible to reduce carbon dioxide in the environment in an environmentally sustainable and worthwhile way,” claimed Greene, who is a fellow at Cornell’s Atkinson Centre for a Sustainable Potential.
