Arrhenius secures funding for carbon removal through microalgae
Horw - Arrhenius AG in the canton of Lucerne has closed a seed funding round. The company plans to use the capital to scale up its technology for the durable removal of carbon from the air using microalgae. Plans include a 500 square meter pilot plant and the first commercial plant abroad.
The cleantech startup Arrhenius has attracted new investors. According to a statement, investors in the seed round include CTA AG from Münsingen, Bern, YOUNG VENTURES AG from Cham, Zug, and business angels Thomas Krumbeck and Ralf Wildenhues. Arrhenius did not disclose the amount raised.
Founded in 2023, the Horw-based company has earmarked the funding to support the next phase of scaling its technology. The plan is to build a 500 square meter pilot plant, where the company will validate its negative emissions technology (NET) for the durable removal of carbon from the atmosphere under real-world operating conditions.
To achieve this, microalgae are cultivated in photobioreactors using natural light and supplied with nutrients from wastewater. During photosynthesis, the algae bind carbon dioxide from the atmosphere. The carbon-rich biomass, which consists of more than 50 percent carbon, is then dried and stored underground for the long term.
In addition to the pilot plant, Arrhenius is also preparing to build its first commercial plant abroad.
In addition to capital, the new investors bring complementary expertise in entrepreneurship, industry and climate innovation. "We thank them sincerely for their trust in our team and technology, and for sharing our vision of a more sustainable future", writes Arrhenius.
