The potential of algae as a biofuel

Algae as a biofuel has the potential to be another renewable energy alternative. However, its limitations are low growth rates and high collection costs.

Artificial intelligence is presented as a solution to solve these limitations. The Texas A&M Agrilife Research group of scientists aims to make algae production reliable and cost-effective for biofuels and apply it as an alternative energy in transportation such as jet aircraft.

The leader of this project is a scientist and professor of Synthetic Biology and Renewable Products in the Department of Plant Pathology and Microbiology, Joshua Jan. The US Department of Energy’s Office of Fossil Energy is funding the research.

Algae-based bioproduction represents one of the best alternatives in terms of energy and carbon to renewable fuels and CO2 capture and utilization.”, say the team of researchers. Despite the great potential and the efforts of science, the commercialization of biofuel from algae is hampered by difficulties in its cultivation conditions, such as the low penetration of sunlight, the dynamics of cultivation, the low yield and the lack of technology for its production. . scale harvesting.

Regarding lighting conditions, algae tend to shade each other, making it difficult for uniform light to enter the entire crop. On the other hand, dehydration of algae once harvested also constitutes high handling costs on a large scale.

If algae biofuel overcomes these limitations, it could become a key to tackling the climate crisis. It would act to reduce carbon emissions and the pressure for dependence on fossil fuels. This would even cause an upheaval in the global bioeconomy.

His most recent project uses an advanced artificial intelligence learning model, which aims to predict light penetration, growth and optimal density of algae. This would allow for a continuous harvest of hydroponically grown synthetic algae, further achieving rapid growth at optimal density to allow for the best light penetration.

The method implemented by this team of scientists managed to break a world record in terms of outdoor biomass production. DOE’s latest target range is 25 grams per square meter per day, and Yuan and his team hit 43.3 grams.

Algae can be used as an alternative energy source for many industries, including aviation fuel.Yuan said. “Algae are a good alternative source of fuel for this industry. It is an alternative raw material for the bioethanol refinery, without the need for pre-treatment. It is cheaper than coal or natural gas. It also provides a more efficient way to capture and utilize carbon.”. Yuan also mentioned that seaweed can be a good food source for animals.

Algae biofuel, an ultimate solution?

Algae biofuel is considered one of the ultimate solutions for renewable energy, but its commercialization is hampered by growth limitations caused by mutual shading and high harvesting costs.

We overcome these challenges by advancing machine learning to inform the design of a semi-continuous algae culture (SAC) to maintain optimal cell growth and minimize cross shading.Yuan said. “This technology has proven to be affordable and helps to boost algae as a true alternative form of energy,” he added.
