Finns create protein out of air and energy
Researchers in Finland have produced a batch of single-cell protein using electricity and carbon dioxide, a method that can be used for food and animal feed.
The method can be further developed for use as food and animal feed, and it releases food production from restrictions related to the environment.
“In practice, all the raw materials are available from the air,” tells Juha-Pekka Pitkänen, principal scientist at VTT. “In the future, the technology can be transported to, for instance, deserts and other areas facing famine. One possible alternative is a home reactor, a type of domestic appliance that the consumer can use to produce the needed protein.”
The method also enables food production where it’s needed, thus freeing up land areas for other purposes.
“Compared to traditional agriculture, the production method currently under development does not require a location with the conditions for agriculture, such as the right temperature, humidity or a certain soil type,” professor Jero Ahola from LUT explains. “This allows us to use a completely automatised process to produce the animal feed required in a shipping container facility built on the farm. The method requires no pest-control substances.”
According to estimates by the researchers, the process of creating food from electricity can be nearly 10 times as energy-efficient as common photosynthesis, which is used for cultivation of soy and other products. The next step the researchers are working on is to begin pilot production.
The study is part of the wide-ranging Neo-Carbon Energy research project by the LUT and VTT. The aim of the project is to develop a completely renewable and emission-free energy system.
