Algae may become a profitable and sustainable fuel alternative in the future. In addition to capturing carbon from the atmosphere, they can reduce dependence on fossil fuels, promoting the bio-economy and combating climate change.

According to the Green Severs portal, a Texas A&M AgriLife Research team is using artificial intelligence to produce algae in record quantities. Its goal is to ensure that challenges seen in previous harvests, such as light exposure and poor cultivation dynamics, are overcome to ensure good crop yields - even at industrial levels.

The project uses an artificial intelligence model that predicts light penetration, growth and density of the algae. This model allows for the continuous harvesting of the algae using the hydroponics technique, in order to maintain rapid growth at the optimum density to ensure the best light availability. During the experimental phase, the group has already managed to harvest 43.3 grams per square meter per day.

As Joshua Yuan, the researcher coordinating the research, says, "Algae can be used as an alternative energy source for many industries, including biofuel and jet fuel. They are an alternative feedstock for the bioethanol refinery without the need for pretreatment. They are less expensive than coal or natural gas. It also provides a more efficient way of carbon capture and utilization," he adds. In addition, the scientist also suggests that algae can be a source of animal feed.
