This is a Portuguese SME with more than 15 years’ experience in civil engineering, health, safety and environment and implementation of energy efficiency solutions.
This equipment is a unit that uses the energy of sea waves and converts it in electricity.
The unit can operate on jetties, marinas and other maritime infrastructures, taking advantage of wave energy due to the difference in height of the free surfaces of two tanks implanted in a jetty, one located on the sea side and the other on the land side using a turbine to produce electricity. The use and transformation of energy will be similar to that of tidal mills and mini hydro plants.
It works with a new concept of harnessing wave energy profiting from the kinetic energy and wave potential and using the maximum wave height. Its operation is independent of the tides.
The unit uses a mini-hydro turbine with a continuous turbine supply, independent of the wave cycle and size.
It can use existing maritime infrastructures and being a modular system, it can use one or more monoblock turbines using little space on the dock. Multiple units can work in parallel.
The electromechanical equipment is installed in a protected area and therefore there is no equipment or moving parts in direct contact with the waves.
It involves low installation costs as well as those concerning ancillary works and the ones related to connection to the electricity grid. It is possible the local use of the energy produced and the kW produced is considered green kW. In periods of higher energy production, it can be used for other purposes, namely hydrogen production and battery charging.
The system minimizes the impact on the receiving environment, with reduced visual impact and does not contribute to any aquatic environment impact. Being a clean energy production unit it has little relevant sound impact and a positive impact on populations.
These units fight coastal erosion, allow the exploitation of aquacultures in the open sea / production of micro algae and in parallel can be used for the production of hydrogen.
The company has all pre-testing works for the verification of the concept and resistance in extreme conditions, tested in wave channel, and is seeking to move this to a next level with self-financing partners, who could contribute to demonstration of the technology with a simulation study over a research or technical cooperation agreement. Ideal partners should have expertise in marine technology and inshore structures. The PT company also looks for investors over financial agreement and is open to form joint ventures with energy sector companies for pilot unit in the marine environment in real conditions.
