HydroWing, which owns Dutch tidal turbine outfit Tocardo, has developed a concept of a floating platform for producing green hydrogen at sea. Sinn Power comes with another exciting development at sea is the first floating ocean hybrid platform that can generate power from waves, wind, and solar.
Blue Floating Energy: Hydrogen
Tidal Hydrogen production, Storage and Offtake – concept comprises up to six bi-directional tidal turbines that generate clean electricity, which is directed through an integrated hydrogen production unit that converts surrounding seawater into the gas. The concept will be demonstrated with the aim of ‘upscaling and rolling out’ larger projects across Europe and globally in the coming years.

Hydrogen Energy: Capacity
The floating platform for producing green hydrogen at sea can hold up to two weeks’ worth of the gas in pressurized storage tanks. Offtake is scheduled autonomously by remote communications, and discharge occurs within a single slack tide.
THyPSO combines the advantages of tidal and hydrogen technologies, ‘mutually overcoming’ technical and financial barriers faced by each technology alone. The project has shifted our focus to a broader and exciting market where we can make use of our tides to provide a more versatile energy mix into the local communities and beyond. HydroWing wants to inspire more meaningful use of green hydrogen in the marine sector as a result of this project.

This project provides a new perspective and clever use of tidal turbines. THyPSO is well suited to the range of Tocardo turbines allowing Hydrowing to effectively scale up as demand for green hydrogen increases into the future.

Blue Floating Energy: Wind, Solar, Waves
Another exciting development at sea is the first floating ocean hybrid platform, which can generate power from waves, wind, and solar.
Blue Floating Energy: Wind, Solar, Waves
German startup Sinn Power has developed a modular maritime platform able to generate renewable energy from waves, wind, and solar sources. Starting later this summer, it hopes to offer solar panel manufacturers the chance to test and demonstrate photovoltaic arrays on a floating platform off the Greek coast as part of an off-grid energy solution.

Blue Floating Energy: Waves
Offshore wave energy conversion (WEC) is nothing new; pioneering new developments are taking place in this field all the time. However, what makes this particular platform unique is that it’s been designed to be modular and extremely easy to connect and expand, so a variety of different combinations are possible.

Blue Floating Energy: Modulair
The modular design has been a critical element since we started developing maritime technologies that allow flexibility and a wide variety of applications. The floating platform can supply renewable energy to islands across the world, for example, and contribute to the worldwide implementation of offshore wind farms.
Blue Floating Energy: Data
Electrical sensors continuously transmit data to diagnostic centers, enabling the early detection of anomalies and preventing potential failures. By analyzing power output patterns, Sinn says they can quickly optimize a service plan for potential customers and anticipate repairs before severe damage occurs. The key, says Sinn, is making this technology affordable.
Each floating unit, or module, consists of four integrated wave energy converters generating power relative to the water conditions. For regions with low potential for wave energy, the unit can also be equipped with an array of 20kW photovoltaic cells. Similarly, up to four small six kWp wind turbines can be fitted. Finally, a combination of all three is also possible, making optimum use of the environmental conditions surrounding the platform. Sinn says there’s no limit to how many units a potential could have.
It's always the same; it's supermodular. We can still use the equal parts, the same electronics, regardless of which configuration is constructed. So, with this strategy, we want to get into volume, get the practice low, and then it's so we can show that wave power is beautiful against solar.

Blue Floating Energy: Base
Based near Munich and with a permanent testing facility in Heraklion, on the island of Crete, the idea has attracted a lot of attention from partners and investors. Impressive as it only took two years to go from patent to prototype.
We are now preparing the floating platform to be used as a showcase to enable full access for potential customers. Politicians and representatives from other European nations have already visited. The next goal is in the autumn when hopefully we'll be able to start marketing our unique electronics set.
