Ecoult offers complete energy storage systems and a lifecycle management program called UBer that supports project development, installation, operation and maintenance.
This document discusses technologies for achieving perpetual mobility and sustainment on water using solar and wind power. It summarizes recent developments in solar photovoltaic and concentrated photovoltaic technologies that have increased efficiency. Concentrated photovoltaics in particular allow for a reduction in the size of solar panels needed while maintaining or increasing power output. The document also proposes using these solar technologies together with battery storage, hydrogen fuel cells, and small wind turbines to create systems capable of powering vessels indefinitely without fossil fuels.

Importantes investigadores de las universidades y de los centros tecnológicos más relevantes del Reino Unido, Portugal y Galicia se dan cita en Santiago de Compostela para trasladar su experiencia y líneas de actuación en investigación y tecnología en el naval en la Jornada de Demostración Tecnológica de la Industria del Naval el próximo 26 de enero.
This document discusses potential business opportunities in auxiliary maritime industries related to international compliance with emissions regulations. Specifically, it outlines opportunities in exhaust emissions control technologies like scrubbers, use of LNG as a ship fuel, offshore wind energy, and tidal/wave energy. Challenges and policies around developing these markets are also reviewed. The Arctic region is also discussed as a potential developing market for oil and gas resources, but environmental and geopolitical challenges are noted.
