Voltaic Marine builds autonomous surface vessels powered by renewables for offshore operations. The vessels use solar panels and wind turbines to enable extended missions collecting oceanographic data, supporting offshore wind farm development, and performing asset inspections. Their platform targets the offshore energy sector, serving wind farm operators, marine survey firms, and research institutions needing persistent presence at sea. The company operates demonstration vessels in European waters, focusing on the North Sea region. Voltaic Marine raised €2.5 million in seed funding in 2023 from investors including Elaia Partners and Offshore Wind Innovation Hub. Founded in 2022 by Richard Phamdo, previously at Wavec Offshore Renewables, the startup collaborates with ports and classification societies for vessel certification.
