"The technology group Wärtsilä has invested a further EUR 1 million in Soletair Power Oy, a Finnish CO2 direct air capture technology company ... This latest investment enables Soletair Power to further its global sales efforts and to scale up the manufacturing of its CO2 capture solution for building ventilation", Wartsila said in a statement.
The start-up's technology involves capturing CO2 and in-house air supplied to a building's ventilation and then combining it with hydrogen, produced by an electrolyser module powered by renewable energy, into hydrocarbons for energy or manufacturing needs.
In April 2019, Wartsila gave Soletair Power Oy the initial funding of 500,000 euros ($600,420).
