FAQ

SINN Power Technology

How does the SINN Power wave energy converter work?


The basic principle is simple: The up-and-down motion of the waves lifts the floating bodies of the individual modules. The floating bodies in turn lift a rod that runs through a generator unit. This is how electricity is generated.




What are the economic advantages of SINN Power's wave technology?


Typical customers currently rely on expensive and climate-damaging diesel generators. From the start, the SINN Power wave energy converter can save electricity costs and CO2 emissions. The unique combination of steady, strong primary energy in ocean waves and the low-cost approach of SINN Power's mass-manufactured modular technology allows for an energy system that reliably covers both baseload and peaks (reducing battery costs) and has lower LCOE than its competitors (mainly diesel generators). Depending on the wave power in the location and the electricity needs of the customer, the number and the size of the wave energy converter modules are individually adjusted. This way, the wave energy converter can always provide the optimal energy supply at the lowest cost.




What are the ecological advantages of SINN Power's wave energy technology?


Thanks to the simplicity and robustness of the SINN Power technology, the first wave energy converter can already replace one diesel generator. Every replaced generator saves about 780 tons of CO2 every year – the equivalent of 195 car trips around the earth. Presently, diesel generators in coastal areas have a capacity of about 22 gigawatts.Replacing all diesel generators in coastal areas with SINN Power wave energy converters would equal the positive climate effect of all renewable energies in Germany taken together.




Are SINN Power wave energy converters already in use on the ocean?


From December 2015, SINN Power installed a single module of the wave energy converter in original size at the Port of Heraklion in Crete (Greece) to test the functionality and corrosion resistance of the components.




How does the SINN Power wave energy converter differ from other marine energy technologies?


Previous developers mostly relied on large and expensive high-tech installations that offered little flexibility for adapting to the customers’ needs and to the wave climate in the specific site. SINN Power takes another path: Its modular wave energy converter is built from mass-produced standard components and not only more cost-efficient, but also easier to transport and maintain. This way, the wave energy converter can also be used in countries with less developed infrastructure, where it replaces climate-damaging diesel generators.





WEC arrays

How big is SINN Power's wave energy converter array?


In the standard version, the floating body of an individual module has a diameter of 2 meters, the entire module is 10 meters high. The modules are connected in an array of variable size, depending on wave lengths at the site. When the wave energy converter array floats a few hundred meters off the shore, it appears near the horizon like a small boat.




How much electricity does the SINN Power wave energy converter array generate?


The output of the wave energy converter is primarily dependent on the power of the waves in the site. The SINN Power wave energy converter uses two advantages of ocean waves: The energy contained in waves is significantly more concentrated than the energy in wind and sun. At the same time, ocean waves are much more continuous than alternative energy sources. This way, the wave energy converter can generate enough electricity to reliably power a larger hotel resort or a small community.​​




Where can the SINN Power wave energy converter array be installed?


In principle, the wave energy converter can be used on coasts all over the world. Waves that are especially suited for energy generation can be found on the coasts of the big oceans. Here wind energy that has accumulated in the ocean water over hundreds of kilometers on the open sea has ‘charged’ them with a lot of power. Near the equator in particular, the waves are more continuous than those in the North Sea or the Atlantic Ocean. This increases the supply security for the customer.​​




What happens to the SINN Power wave energy converter array if there is a storm?


The wave energy converter is designed to withstand the maximum wave height of a specific site plus a safety margin. Tests in the wave tank of the University of Florence showed that the standard mooring system is able to withstand the equivalent of 7 meter high breaking waves.





WEC modules

How big is a SINN Power wave energy converter module?


The size of the SINN Power wave energy converter module is highly adaptable to match the requirements of the various applications and generate the optimal energy output. SINN Power uses a combination of standardized parameters and customized engineering to always ensure the optimal energy output and safe operation in all wave climates.




What applications are the SINN Power wave energy modules suited for?


The SINN Power wave energy modules are highly versatile and can supply electricity to:

  • Offshore structures such as oil rigs, pumping stations
  • Offshore wind turbines
  • Aquacultures and fish farms
  • Offshore and marine research stations
  • Ports and marinas




Are SINN Power wave energy converter modules already in use on the ocean?


In December 2015, SINN Power installed a single module of the wave energy converter in original size at the Port of Heraklion in Crete (Greece) to test the functionality and corrosion resistance of the components. In May 2016, SINN Power continued the tests with an updated and improved module. By collecting and analyzing the data from the long-term tests in Heraklion, SINN Power continuously improves the reliability and energy efficiency of the wave energy converter technology.
