Advantages of wave energy are; zero emissions, renewable and abundant supply, simplicity of utilization, multiple conversion methods, predictability and flexibility.
This article discusses the advantages of wave energy, as follows;
1). Zero Emissions (as one of the Advantages of Wave Energy)
Wave energy is better for the environment than fossil fuels and even nuclear energy, because the overall process of wave energy conversion does not involve significant environmental impacts compared to these alternatives.
To bolster output, wave energy can be harnessed in combination with other clean energy resources like solar and wind, in hybrid systems . This is yet another advantage of wave energy, as it shows that it can be optimized in a flexible manner.
2). Renewable and Abundant Supply
Wave energy is completely renewable, because it comes from natural resources and processes like water, wind and solar radiation, which are all continuous and naturally sustainable.
The scale and geographic span of oceans imply that wave energy is abundant, and can be used to meet a great portion of Earth’s energy needs if harnessed effectively.
In addition to being renewable and abundant, wave energy is also fairly reliable and consistent, especially when compared to other renewable energy resources like wind and solar, that occur intermittently in peaks and troughs .
3). Simplicity of Utilization (as one of the Advantages of Wave Energy)
The basic concept behind the use of wave energy is a simple one, which involves capture and conversion using electromechanical devices.
This is an advantage, because it reduces the technical requirements in terms of knowledge and skill, for successful execution of wave energy projects.
It also implies that wave energy systems require less sophistication, and may be less-demanding in terms of capital and operational costs than some alternatives.
4). Multiple Conversion Methods
This is beneficial in that it provides some degree of flexibility in wave energy development, and enables operators to opt for the most suitable approaches to optimize the performance of wave energy systems in any given scenario.
The 3 main types of wave energy technologies are; oscillating water column, wave absorbers, and overtopping devices.
The main methods of converting wave energy are; kinetic-to-potential, kinetic-to-mechanical, and mechanical-to-electric conversions.
5). Predictability and Flexibility (as one of the Advantages of Wave Energy)
Wave energy is predictable in terms of its energy density, supply rates and consistency , especially when compared to other renewable energy resources like solar and wind.
The predictability of wave energy is a huge advantage as it can be used for proper planning when carrying out energy development projects, so that the capital costs are evaluated based on potential energy output over the entire lifetime of a wave energy converter, farm/park or power plant.
Wave energy is flexible in that it can be used for a variety of purposes, harnessed through multiple methods and technologies, and managed effectively.
Energy management in the wave power sector can be achieved through energy storage, distributed energy resources management systems (DERMS), smart grids and system modifications.
