We’ll also peer into the future, examining how this technology could revolutionize food supplies not just on Earth but even in space.
Birth of Solein: Protein Production from Air and Microbes
Solein’s journey began with a simple yet radical idea: to create a sustainable protein source using resources that are abundantly available but largely untapped. This brainchild of Solar Foods, a Finnish startup, became a reality thanks to the ingenuity of its founders, Pasi Vainikka and Juha-Pekka Pitkänen. They envisioned a method of producing food that doesn’t rely on traditional agriculture – no fields, no livestock, and no seasonal harvests, just air, water, and renewable energy.
The core ingredient in Solein production is a microbe. Specifically, it’s a type of hydrogen-oxidizing bacteria, a microorganism that can convert simple compounds into complex nutrients. These bacteria were selected for their ability to use gases like hydrogen and carbon dioxide as their primary sources of energy and growth. When provided with the right conditions and nutrients, they multiply rapidly and produce a high-protein biomass.
Solar Foods cleverly harnesses this natural microbial process in a controlled environment. The process is akin to brewing beer, where specific microbes are cultivated and fed to produce a desired output – in this case, a protein-rich substance rather than an alcoholic beverage. This approach minimizes environmental impact and ensures a steady and scalable production of protein irrespective of external conditions like weather or soil health. Essentially, Solar Foods has pioneered a way to produce what they call “the 21st-century potato,” but instead of growing it from the ground, they grow it from the air.
How Solein is Made: Solar Foods’ Sustainable Protein Science
Understanding how Solein is created can seem complex, but let’s break it down step-by-step in simple terms. The production of Solein revolves around a process called fermentation, something we use in everyday foods like yogurt, bread, and beer. However, instead of using sugars or grains, Solar Foods uses gases from the air, specifically carbon dioxide (CO2) and hydrogen (H2).
1. Raw Materials
The primary inputs are basically air and water. The process begins with capturing CO2 and water from the air. Using renewable energy, water is then split into hydrogen and oxygen through a process known as electrolysis.
2. Bioprocess
The hydrogen and CO2 are fed into large tanks, known as bioreactors, where they meet our star microbe – the hydrogen-oxidizing bacteria. These microbes are like tiny living factories that convert these gases into a substance packed with protein. Alongside these gases, the microbes are also given essential nutrients like nitrogen, phosphorus, and potassium, similar to how plants get nutrients from the soil.
3. Fermentation
Inside the bioreactors, a process akin to fermentation occurs. The microbes munch on the gases and nutrients, growing and multiplying rapidly. This process is incredibly efficient – far more so than traditional photosynthesis in plants. In fact, it is about 20 times more efficient than the best performing crops, meaning it produces a significant amount of protein using very little input.
4. Harvesting
As the microbes grow, the liquid in the bioreactor becomes dense with biomass. This thick microbial soup is then separated, and the solid material is collected via centrifugation (a method of spinning the liquid really fast to separate solids from liquids).
5. Protein Powder
The resulting solid material is dried to form a fine yellow powder. This powder is Solein, which is composed of about 60-70% protein, making it exceptionally nutrient-dense. Additionally, it contains dietary fibers, fats, vitamins, and minerals that are essential for human health.
6. Food Production
The final Solein powder can then be used in a myriad of food products. It can be incorporated into everything from pasta and snack bars to dairy alternatives and meat substitutes. Its versatility is one of its greatest strengths, allowing it to blend seamlessly into various dishes without altering taste or texture significantly.
Solar Foods Eco Protein Leaps Forward
In essence, Solar Foods has created a groundbreaking method to produce food that is not only sustainable but also capable of feeding a growing global population without degrading the planet. This bioprocess represents a significant leap in food technology, one that aligns with the urgent need for innovative solutions to global food security challenges.

In contrast, Solein’s production process is a game-changer when it comes to preserving our planet’s resources.
Water Efficiency
Producing Solein requires a fraction of the water needed for traditional farming. To put this in perspective, it uses 100 times less water per kilogram of protein compared to animal farming methods. This is crucial as freshwater resources globally are becoming increasingly scarce.
Minimal Land Usage
Unlike conventional agriculture that demands vast tracts of arable land, Solein production can be carried out virtually anywhere – even in places where farming isn’t possible. Solar Foods’ fermentation process requires no agricultural land. It operates within an industrial setting, meaning there’s no need to clear forests or displace ecosystems to make room for crops or livestock.
Lower Carbon Footprint
In terms of emissions, Solein production is astoundingly efficient. The carbon dioxide utilized in the process is repurposed, effectively turning a greenhouse gas into a valuable resource. This results in a protein source that has approximately 1% of the carbon footprint of meat and only 20% of the footprint of plant-based proteins. Considering the urgent need to reduce global greenhouse gas emissions, this reduction is significant.
No Chemical Runoff
Another environmental benefit is the absence of harmful chemicals. Traditional farming often involves pesticides, herbicides, and fertilizers, which can lead to pollution and degradation of water bodies. Solein’s bioprocess does not require these chemicals, thus preventing potential pollutant runoffs into rivers and oceans.
