In a groundbreaking initiative, Vaxa Technologies in Iceland is revolutionizing food production by harnessing geothermal energy to cultivate microalgae, a nutrient-dense food source. The facility, illuminated by pink-purple light, utilizes renewable energy to grow algae and bacteria like spirulina, which have vast potential in addressing global food insecurity. Despite challenges in its acceptance and textural appeal, the microalgae market is projected to soar, offering an alternative for future food solutions.
Transforming Food Production: Iceland's Microalgae Revolution
Transforming Food Production: Iceland's Microalgae Revolution
Iceland's Vaxa Technologies is pioneering sustainable food production through innovative microalgae farming.
In the shadow of Iceland’s largest geothermal power station lies a revolutionary facility redefining food production—Vaxa Technologies. Situated about 35 minutes from Reykjavik, this high-tech indoor farm cultivates microalgae under a vivid pink-purple glow. General manager Kristinn Haflidason guides visitors through this futuristic setup, where illuminated panels and bubbling columns of water create the perfect environment for growing these tiny aquatic organisms.
For centuries, humans have consumed larger seaweed, or macroalgae, while microalgae has been less prevalent despite its historical use in ancient cultures. Today, scientists and entrepreneurs are unlocking its potential as a sustainable, protein-rich food source. At Vaxa, the primary species cultivated includes Nannochloropsis, which serves as human food and fish feed, alongside Arthospira (spirulina), known for its dietary benefits and vibrant color.
The facility is uniquely positioned to utilize clean energy and resources from the adjacent geothermal station. With a carbon-negative footprint, Vaxa’s operations rely heavily on renewable energy, emphasizing the need to harness low-impact energy sources for energy-intensive food production processes.
Asgær Munch Smidt-Jensen, a food technology consultant at the Danish Technology Institute, notes the rarity of such integrated setups and the benefits of utilizing geothermal energy and CO2 emissions from the power plant to grow algae. Vaxa’s controlled environment optimizes the algae's photosynthesis using specific light wavelengths, enabling efficient growth and daily harvesting of 7% of the crop, potentially yielding 150 metric tonnes of algae annually.
The nutritional value of microalgae presents a promising solution to food insecurity, where its rich composition of protein, omega-3 fatty acids, and vitamins could significantly impact dietary practices. The global market for microalgae is estimated to reach $25.4 billion (£20.5 billion) by 2033, with various companies experimenting with portable bioreactor systems to capture CO2 emissions while producing food.
However, experts like food scientist Malene Lihme Olsen from Copenhagen University point out that there remain challenges, particularly regarding taste and digestibility. There's an ongoing need to develop microalgae while also considering public perception and acceptance of this alternative food source.
At Vaxa, Haflidason offers a taste of the harvested microalgae, resembling unappetizing green sludge but boasting a neutral flavor akin to tofu. The vision is to integrate microalgae into everyday food products, enhancing their nutritional content without altering familiar flavors.
Ultimately, Vaxa Technologies represents a new frontier in sustainable agriculture and nutrition, blending advanced technology, renewable energy, and innovative thinking to tackle the global challenge of food scarcity – all while paving the way for a new chapter in dietary practices.
