So says Robert Brown, a professor of engineering at Iowa State University and a leader of the university’s Initiative for a Carbon Negative Economy and its Bioeconomy Institute. Those are interdisciplinary campus efforts to develop ways to remove carbon dioxide from the atmosphere by growing plants or algae, making them into fuels and burying their carbon residues in soil -- and make money doing it.
The notion that we can generate wealth and remove CO2 from the air is obviously appealing. As atmospheric concentrations of CO2 rise and climate risks grow, so does the need for carbon-negative technologies that pull CO2 from the air, as plants do, and then store it underground or deep in the ocean.
