The power device, which will be deployed during the autumn, will provide power for The Deep submarium.
The approval has been issued with a Transport and Works Act Order following a decision by the UK Department of Energy and Climate Change to allow deployment of the Neptune Proteus NP1000 demonstrator and the installation of a shore bridge in the Humber.
Neptune Renewable Energy finance director Glenn Aitken said as the Humber region develops into a leading UK centre for renewable energy, the company needs to raise awareness of the potential for tidal power business as a significant contributor.
"It has some clear advantages over wind power including being a totally predictable and continuous source of clean energy as well as being visually unobtrusive," Aitken said.
The company is now developing its first commercial array of five advanced Neptune Proteus NP1500s that are also planned for deployment in the Humber and will generate enough energy to power about 5,000 homes.
