Arkadia Space develops high-performance green chemical propulsion systems for satellites and spacecraft, offering a non-toxic and cost-effective alternative to traditional hydrazine-based fuels. The company's propulsion systems utilize high-concentration hydrogen peroxide and a proprietary green fuel. To manage qualification and acceptance testing in-house, the startup operates its own private orbital engine test center at the Castellón Airport. In March 2026, the company secured a significant €12 million priced equity round, which included €6 million from the European Innovation Council Fund alongside private capital.
