Wake-up time for marine energy is finally here, in the form of new devices that harvest the natural motion of waves, tides, and currents.

When the topic turns to marine energy, building a better mousetrap is the name of the game. Wind, waves, and tides all combine to provide a practically limitless source of renewable energy. That’s an alluring target for innovators. The challenge is to engineer marine energy conversion systems that can withstand the constant pressure of wind, waves, and tides while warding off saltwater corrosion, and the victors are beginning to emerge..

“From the mixing of 1 m³ of river water with 1 m³ of sea water, 0.5 kilowatt hours of electricity can theoretically be obtained at 25 oC. This corresponds to a power of 1.8 MW from a flow rate of 1 m³/s fresh and 1 m³/s salt water,” REDstack explains.leverages docks, locks, and other existing infrastructure to harvest tidal energy with vertical axis turbines. The turbines can also be installed in open water.

“The Dutch government would like to implement a nature inclusive multi-use park filled with innovative technologies, such as marine energy, in a current wind park optimising the used space,” they added. “The Dutch approach to multi-use could set the norm for other countries.”Activity in the green hydrogen field is beginning to surface in the Baltic Sea, where six EU states are exploring the idea of usingToo bad Russia is going to miss the Baltic Sea marine energy boat.
