By redefining energy management, optimizing storage and production capabilities, our system allows you to sail free from energy constraints.
In 1997, Philippe Pallu de la Barrière won the European Solar Boat Challenge, revealing the immense potential of renewable energy at sea. The following year, he founded Alternatives Energies and launched the first 1000/0 electro-solar ferry in the port of La Rochelle.
Since then, Alternatives Energies has built a legacy of innovation and resilience, overcoming technical challenges to deliver cutting-edge energy solutions for the maritime industry worldwide.
