An unconventional mélange of algae, eucalyptus and bioenergy with carbon capture and storage seems to be a quirky ecological recipe. But, scientists from Cornell University, Duke University, and the College of Hawaii at Hilo have an notion that could use that recipe to help electrical power and give foods protein to large areas of the globe — and at the same time eliminate carbon dioxide from Earth’s environment.

“Algae may be the essential to unlocking an crucial unfavorable-emissions engineering to overcome local climate improve,” said Charles Greene, Cornell professor of Earth and Atmospheric Sciences and a co-creator of new study released in Earth’s Foreseeable future, by the American Geophysical Union.

“Combining two technologies — bio-power with carbon capture and storage, and microalgae production — may possibly appear like an odd couple, but it could offer adequate scientific synergy to enable address earth starvation and at the very same time reduce the stage of greenhouse gases that are changing our climate technique,” Greene stated.

Dependent on an notion first conceptualized by co-writer Ian Archibald of Cinglas Ltd., Chester, England, the scientists connect with the new integrated technique ABECCS, or algae bioenergy with carbon capture and storage. The method can act as a carbon dioxide sink whilst also generating meals and electricity. For illustration, a 7,000-acre ABECCS facility can generate as a great deal protein as soybeans generated on the very same land footprint, even though concurrently producing 17 million kilowatt hrs of electricity and sequestering 30,000 tons of carbon dioxide for every calendar year.

The ABECCS system’s economic viability relies upon on the benefit of the nutritional solutions becoming generated and the cost of carbon. Even with out a selling price on carbon, microalgae production — in a fish-farming, aquacultural sense — is commercially practical now if the algae are priced as a fishmeal substitute in aquafeeds.

“In the foreseeable future, as the cost of carbon raises, ABECCS has the opportunity to reduce carbon dioxide in the environment in an environmentally sustainable and financially rewarding way,” mentioned Greene, who is a fellow at Cornell’s Atkinson Centre for a Sustainable Future.
