The ocean thermal energy is abundant. The global total is about 40 billion kW. The ocean thermal energy conversion (OTEC) is clean and renewable, the power generation is stable, and the energy storage has high capacity. Active exploitation of ocean thermal energy resources is of great significance to realize the strategy of maritime power. In view of the efficiency limit of a traditional OTEC, authors propose an approach of a multi-energy complementary OTEC system that they can improve the efficiency of this system. The approach sets parameters at the system level and integrates solar energy, wind energy, energy storage and OTEC. For example, a 1MW integrated power generation system is designed and simulated by means of computer aided design and of conducting a model-based simulation, respectively. The efficiency of the complementary OTEC system with solar heating can reach 13.12%. In this article, the basic principle and working process of the approach are analyzed, and the system efficiency is calculated. The results show that, in comparison to the traditional OTEC, the complementary system of OTEC can improve the ratio of power generation output efficiency, stability and ocean energy utilization.

This article presents a perspective of the several modern alternative energy generation technologies. Moreover, authors facilitate the case study of the application of an emerging energy blockchain (EBC) technology and the Published Energy Sources (PES). A methodical analysis utilizes the EBC input parameters as follows: power generation such as multi-energy complementarity, energy storage, and the smart grid power that has a smart meter and/or control within the EBC system. On the other hand, the EBC technology has several variables as output that includes the following: (1) power consumption focusing on renewable energies; (2) technology enabling financial saving and earning method; (3) peer to peer energy transaction according to the EBC platform.

It is extremely important to achieve maximal efficiency of an alternative energy system, as such; it provides the maximum power output. In order to be maximally efficient in utilizing the available energy, researchers will study several key factors that can enable the best sustainable energy in terms of utilizing alternative energies. They have studied several methods to design the best-distributed energy system which implements the alternative energies, energy storage, and the advanced materials for the alternative energy generation. In terms of the solar photovoltaic technologies, e.g., researchers have studied the perovskite solar cells. Perovskite solar cells are highly favored for their wide, tunable band gap and solution process ability. Stellar rise of the perovskite solar cells application partly attributed to factors like high energy efficiency. These factors include innovative design such as the tandem structure, tunable band gap, and encapsulation for each layer. At present, their single-junction efficiencies are comparable to those of multi-crystalline silicon, cadmium telluride and copper indium gallium selenide. Finally, researchers have studied an energy storage system at a capacity of 3MegaWattHour. This system can enable a maximum energy output that entails a system including such key factors as the alternative energy generation, energy storage, and an advantageous distributed energy system.
