Cutting-edge methods for converting renewable marine energy are developed by scientists of BAS

Three unique natural energy conversion technologies are being developed by scientists at the Centre for Hydro and Aerodynamics at the Institute of Metal Science, Equipment and Technologies of BAS. The developments are the result of research aimed at efficient use of the vast natural resource and decarbonisation of maritime transport. New wave energy converters The aim of the technology is to use passive methods of auxiliary propulsion that will significantly lower fuel costs and harmful emissions of ships with conventional internal combustion engines. The basic idea is to use the wave energy contributed by the ship's vertical oscillations during wave motion to generate auxiliary propulsion and/or electrical power. Using wave energy to generate electricity is not a new idea. The innovation of this development lies [...]
