“Algae Power Plant” Removes as Much CO2 As An Acre of Trees

Artificial Intelligence (AI)-focused technology company Hypergiant Industries announced a machine that utilizes algae to remove carbon dioxide from the air. The company stated that the underappreciated plant is “one of nature’s most efficient machines.”

The device measures 3ft/0.91m wide and 7ft/2.13m tall. Regardless of its relatively small size, it can remove an entire acre of trees worth of carbon. They estimate this to be equivalent to approximately two tons.

Here are more precise measurements.. The prototype for the machine measures 3′ x 3′ x 7′ and can hold 55 gallons of water and algae.

On the company’s website, they state that these plants require CO2 and light to grow.

“The light can be from the sun, or in this case, artificial light. The algae and water are pumped through a series of tubes to maximize their exposure to light sources lining the inside of the Reactor.”

How Algae Could Help Save the Environment

HyperGiant Industries has already made a working prototype for the carbon footprint-reducing power plant. Furthermore, they envision it in offices and on top of buildings throughout cities.

Algae powers the bioreactor.

“What’s amazing about algae is it’s really cheap and it’s easy to grow—the core things it needs are sunlight, CO2, and water,” Ben Lamm, CEO and founder of Hypergiant Industries, told Fast Company.

Algae grow a lot more quickly than trees, so it can take carbon out of the air much more efficiently. The company estimates that the device can remove two tons of carbon per year. Machine learning software oversees the whole process inside the Eos bioreactor. A.I. manages light, temperatures, and pH levels to ensure maximum production and growth of the plants.

Hypergiant usually makes AI-technology for aviation, space exploration, and defense industries. However, it saw an opportunity to use machine learning to create better algae-run devices that could operate on a mass scale.

The team took the project on after analyzing ways that the company could make an impact on climate change. “As an emerging tech company that’s working in the field of AI and robotics and all of these super interesting things, we have not just an opportunity, but we have a responsibility to make some of our R&D lab time focused on the some of the biggest challenges,” Lamm says.

The device is a closed system that works indoors. It connects to an HVAC system to reduce CO2 levels inside and clean the air. The algae in the machine grows inside of tubes and a water tank in the device. The plant grows because the tubes are filled with outside air and exposed to artificial light. Hypergiant Industries claims that the technology used to create the machines is so efficient that it’s 400 times more effective at removing carbon than trees making up the same footprint.

The company is working on DIY plans so people can build the bioreactors at home.

As the algae grow inside the device, it can be harvested. Then, the harvested product could be used to make products such as fertilizer, food, makeup, and perhaps even fuel one day in the future. The company says it will have different sized machines in the future depending on the customers’ needs.

Because the plant can have such diverse uses, the company will have to think on a large scale to make it work. “There’s nothing new about the idea of growing algae to sequester carbon, and a few dispersed bioreactors alone are not going to reverse climate change,” Lamm says.
