Marine

Technical challenges: Extracting energy from the sea can be technically challenging, as equipment must be able to withstand the harsh marine environment.

Cost: Many forms of marine energy generation, such as wave and tidal power, intail complex development and this entire process can be too expensive to install and maintain.

Environmental impacts: There are concerns about the potential impacts of marine energy generation on the marine environment, including effects on wildlife and habitat destruction.

Intermittency: Many forms of marine energy, such as wave and tidal power, are intermittent and may not be available on a consistent basis. This can make it difficult to integrate into the electricity grid.

Public perception: Some people may be opposed to the development of marine energy projects due to concerns about the visual impact or potential impacts on the local environment.
