Climate change and global warming are increasing their impact day by day, and renewable energy sources are of great importance to combat climate change. scientistsdiscovered an unexpected source for carbon-negative renewable energy: algae, the source of oxygen in the sea.

Algae, which consist of many different organisms, photosynthetic properties attracts attention with. In other words, they produce oxygen and energy using sunlight, water and carbon dioxide. Scientists believed that if they could use this process, they could also capture carbon from the atmosphere. Algae open this path.

Carbon-negative energy production

at Concordia University From the Optical-Bio Microsystems Laboratory The research led by Kirankumar Kuruvinashetti used algae to create microphotosynthetic power cells. Kuruvinashetti, “Photosynthesis produces oxygen and electrons. Our model captures electrons, allowing us to produce electricity,” said.

In this model only per piece 2 centimeters by 2 centimeters Anode and cathode were used in the electrodes. The two plates were separated using a membrane. When the algae photosynthesize, electrons are released and microelectrodes on both sides of the membrane are suspended in a solution in the anode chamber. In addition, this method does not require direct sunlight.

According to the researchers, using algae in this way is safer and more sustainable than some existing renewable production processes. Muthukumaran Packirisamy, the lead author of the study, said: “Our system meets the requirements of photovoltaic cells. silicone production technology No dangerous gases or microfibers are used, which are necessary for this. In addition, silicon computer chips are not easy to convert. We use biocompatible polymers so that the entire system is easy to break down and very cheap to produce.” he said.
