A fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes, one positive and one negative, called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes. Every fuel cell also has an electrolyte, which carries electrically charged particles from […]

Natural gas is a major source of energy. Liquefied natural gas or LNG is natural gas that has been converted to a liquid form for the ease of storage or transport by cooling natural gas to approximately −162 °C. Afterwards, it is stored at essentially atmospheric pressure. Liquefied natural gas takes up about one six hundredth the volume of […]

Solar Ingot Wafer is a kind of raw materials used for solar cell. Generally, this material mainly by the high-purity polysilicon feedstock crystal or ingot obtained by pulling ingots, after cutting by the steel wire into very thin (200 microns) round or square of the film which is called silicon wafer. The increasing capacity and production of […]

Despite the progress made to date by commercially available lithium ion (Li-ion), advanced lead-acid, flow, and molten salt batteries, the path toward the commercialization of new battery chemistries continues. The next-generation advanced battery chemistries at laboratory-scale research or pilot-scale production levels today include lithium sulfur […]

Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means. An electrically powered spacecraft propulsion system uses electrical energy to change the velocity of a spacecraft. Most of these kinds of spacecraft propulsion systems work […]

WTE (Waste-to-Energy) or energy-from-waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste. WTE is a form of energy recovery. Most WTE processes produce electricity and/or heat directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol […]

Solar PV is one kind of device made from crystalline silicon or thin film which converts solar energy into electricity by a process known as the photovoltaic effect. The key indicator for solar PV is conversion efficiency. China is still the biggest market in the global Solar PV market, about 50% market share in 2015, the annual production is more […]

Hydro turbine generator unit is refers to the generating equipment which converts hydro-energy into electrical energy. It is the main power equipment to generate electric energy in hydropower plants. Hydro turbine generator unit mainly consist of the hydro turbine and generator. The role of the turbine is to transform the energy of water into […]

Energy storage battery for microgrids is an energy reservoir that can store electrical energy and supply energy when required. Such a battery system has the added advantage of matching generation to the time of use and enables peak-shaving applications. Battery-based energy storage is more environmentally-friendly than traditional diesel generators […]

Stationary fuel cells generate electricity through an electrochemical reaction, not combustion, providing clean, efficient, and reliable off-grid power to homes, businesses, telecommunications networks, utilities, and others. Stationary fuel cells are quiet and have very low emissions, so they can be to be installed nearly anywhere. These systems […]
