Sustainable Energies

Dahi Bondad Group is one of the pioneers of implementing sustainable energies in the middle east. In this field, our experts are capable of running EPC projects using sustainable energy for a variety of situations.

Our services for Sustainable Energies:

Hydro-electric

Wave Energy

Solar Power

Wind Energy

Hydroelectric power plants

As the Dahi Bondad Group has experienced and specialized staff in the fields of engineering, procurement, construction, and management of hydroelectric and industrial power plants, all the projects that are undertaken by the Group can be easily designed, installed, and delivered as a stand-by power plant/ factory. The followings are Dahi Bondad Group’s activities regarding the production of different hydroelectric power plants:

Wave Energy

Thanks to the mechanical energy generated by the motion of the waves, it is possible to generate electricity by the use of special water turbines. One of the advantages of power generation by wave energy is uninterrupted power generation. This energy source has the following characteristics:

Solar Energy

In terms of energy production from renewable sources, the Dahi Bondad Group has concentrated on one of the most efficient sources of energy which is obtained from the most readily available and most suitable energy source, the sun. The exploitation of solar energy for generating off-grid and on-grid electricity is done in several ways. Dahi Bondad Group can provide the necessary equipment and build a power plant by relying on the project engineering process and reviewing information and data to provide the most appropriate, optimal, and economical source based on its clients’ needs.

Concentrated Solar-thermal Power (CSP)

Dahi Bondad Group specializes in Concentrated Solar-Thermal Power (CSP), the operation of which is based on the reflection of sunlight and focusing on a collector to provide the heat needed to evaporate the liquid, often water. Then hot steam is used to spin the turbine or move the reciprocating motor piston and in practice, the mechanical actuator rotates the electrical actuator to generate electricity. The solar thermal system works based on two technologies:

Central tower: focusing the reflection of mirror light on the central collector tower

Parabolic trough: in this method, parabolic mirrors (concave), with a tube containing heat transfer oil in the center, are heated by concentrating the heat on the oil tube, evaporating water inside the channels and pipes, and are transmitted directly to the turbine or engine.

Solar energy (photoelectric)

Dahi Bondad Group also excels in providing services in the realm of direct electricity generation from the sun. Our Photovoltaic (PV) systems come equipped with mobile collectors designed to efficiently harness sunlight to the fullest extent. Specifically tailored for uneven solar fields, these collectors are capable of tracking the movement of the sun. This innovative feature not only enhances overall plant efficiency but also overcomes the limitation of being limited to flat areas.
Moreover, the energy captured is converted directly into electricity, which can then be stored through our hydrogen tank and battery energy storage system (BESS). This advanced technology ensures efficient and reliable storage of electrical energy.

Molten salt energy storage

The biggest weakness of the solar thermal system is energy storage. In order to generate electricity during nighttime or under unfavorable cloudy weather conditions, thermal energy needs to be stored. In thermal-solar power plants, the process of storing thermal energy is accomplished through the use of Thermal Energy Storage (TES) reservoirs. These thermal reservoirs can contain a heat-absorbing fluid (Thermal Energy Storage Fluid, TESF), such as molten salt, thermal oil, or CO2 gas.
The energy storage process operates in such a way that the heat transfer fluid is conveyed from the receiver units to the heat exchangers within the thermal reservoirs, facilitating the exchange of heat between the heat transfer fluid and the material inside the thermal reservoir. Dahi Bondad Group stands as a pioneer in offering these storage systems.
