Tampere, Finland-based Liquid Sun, a company specialised in creating sustainable fuels, announced that it has secured nearly €4M in funding from Voima Ventures, Failup, and Business Finland to build an eSAF (sustainable aviation fuel) demonstration unit.
“Securing significant funding and oversubscribing the investment round in such a challenging market situation demonstrates that Liquid Sun has proven in a very short time to be a serious player in the e-fuel market. Now, the real work begins as we start scaling up the production of eSAF to an industrial scale, and through that, help drive Finland towards its emission reduction goals and a cleaner future,” says Samuel Thesleff, Chairman of Liquid Sun’s board.
The announcement comes a year after raising €1M in funding.
The funding will help the company develop Finland’s first testing facility for eSAF production.
Liquid Sun: Pioneering eSAF production
Founded by Dr. Pasi Keinänen (CEO), Samuel Thesleff (Chairman), Panu Nordlund, Liquid Sun is transforming two of the most abundant resources on Earth — carbon dioxide (CO₂) and water into a synthetic aviation fuel.
Using its proprietary low-temperature electrolyser, it converts these elements into eSAF, a renewable alternative to fossil-based jet fuels.
As a result, the company’s solution addresses a key global issue: the aviation industry’s significant greenhouse gas emissions.
With EU rules requiring 70 per cent of aviation fuel to be sustainably produced by 2050, Liquid Sun’s technology provides an effective solution to meet these climate goals.
Their upcoming 66-square-meter demonstration plant will be the first significant step toward large-scale eSAF production.
The investor
Based out of Helsinki, Voima Ventures helps founders accelerate the growth of deep technology ventures to global markets.
“At Voima Ventures, we believe in the transformative power of deep tech,” adds Pontus Stråhlman, Partner at Voima Ventures. “Liquid Sun’s ability to turn CO₂ into renewable fuel isn’t just innovative, it’s a much-needed solution for the aviation industry and a critical step toward a more sustainable planet.”
