Chapter 1

Fundamental and principles of the ocean energy system

Abstract

The capability of creating power from ocean streams is colossal. The energy of the ocean is an inexhaustible source that has an advantage in a future energy showcase compared to other sustainable power sources due to its high reliability. Additionally, ocean energy innovations can provide CO₂ emission-free power, and empower energy security and add to economic development and the creation of employment in beachfront and remote areas. This chapter includes the principles and types of ocean energy systems and also describes separately the basic principles of tidal energy, wave energy, and offshore wind energy systems. Finally, this chapter also discusses the worldwide and Indian scenarios for ocean energy systems.

1.1 Introduction

In physics and the field of engineering, energy is a versatile property of a existing system that cannot be directly effect but can be evaluated from one circumstance to another with certain performance parameters. Energy plays an important role in any physical system and in different engineering applications, but it is difficult to give a definition of energy in a broad way because one form of energy can be converted into other different forms of energy. However, the most frequent definition is that it is the capability of a system to perform the desired work. A running person is said to be more energetic compared to a sleeping person. In physics a moving particle is said to have more energy than an identical particle at rest. The characterization of work in engineering physics is the action of a force throughout a distance and energy is dissipated through the workdone. If any human being pushes an entity “n” meters against a conflicting force of “f” newton, f_n joules (newton-meters) of work has been done on the given entity; the person’s body has lost f_n joules of energy and the entity has gained F_x joules of energy. The SI unit of energy is given by the joule (J) (the equivalent to a newton-meter or a watt-second), the CGS unit is the erg, and the Imperial unit is the foot-pound. Other energy units, such as the electron volt, calorie, BTU, and kilowatt hour (1 kWh¼3600 kJ), are used in specific areas of science and engineering. Energy is hugely significant in engineering due to the law of conservation of energy, which states that energy can neither be created nor destroyed but can be changed from one form to another form. For example, in a mixer grinder, electrical energy is converted into mechanical and sound energy. A hair dryer is one of the best examples that shows how one form of energy is converted into a different form of energy. That is because in a hair dryer electrical energy is converted into mechanical energy, thermal energy, and sound energy. Both examples show the phenomenon of energy transformation because energy transformation is the change of energy from one form to another.

Energy transformation occurs everywhere, every second of the day. Energy is converted from one form to another form, for example, in fuel cells chemical energy is converted into useful electric energy. For electricity generation through hydro energy, first the gravitational potential energy is converted into kinetic energy and then the kinetic energy is converted into useful electric energy through a DC or AC generator. Carnot’s theorem and the second law of thermodynamics present some difficulties regarding when energy can be transformed into other forms of energy by work and heat. Energy is a scalar as well as a vector quantity because the direction of conversion and transformation of energy is elaborated by entropy considerations. Most energy transformations are done at a small scale, but certain larger transformations, such as the transformation of electrical energy, are possible with the help of additional equipment. The transformation of energy into constructive work is an innermost and primary part of thermodynamics. At the primary level, the transformation of energy is done in two ways: reversible thermodynamics and irreversible thermodynamics.

In the mechanical-to-electrical analogy, thermodynamically reversible is related to renewable energy sources and thermodynamically irreversible is related to nonrenewable energy sources. In this case, the energy must partially continue as heat and cannot be entirely recovered as a useful form of energy. Electrical energy is the most important form of energy because it is used to generate electricity and in daily life lot of work is done through electrical energy. The generation of electrical energy has been always cate...
