Factory building power conversion technology

At the request of the government of Japan under its G20 presidency, the International Energy Agency produced this landmark report to analyse the current state of play for hydrogen and to offer guidance on its future development. The report finds that clean hydrogen is currently enjoying unprecedented political and business momentum, with the number of policies and projects around the world expanding rapidly. It concludes that now is the time to scale up technologies and bring down costs to allow hydrogen to become widely used. The pragmatic and actionable recommendations to governments and industry that are provided will make it possible to take full advantage of this increasing momentum. Hydrogen and energy have a long shared history — powering the first internal combustion engines over years ago to becoming an integral part of the modern refining industry. It is light, storable, energy-dense, and produces no direct emissions of pollutants or greenhouse gases.

Energy conversion , the transformation of energy from forms provided by nature to forms that can be used by humans. Over the centuries a wide array of devices and systems has been developed for this purpose.

Some of these energy converters are quite simple. The early windmills, for example, transformed the kinetic energy of wind into mechanical energy for pumping water and grinding grain. Other energy-conversion systems are decidedly more complex, particularly those that take raw energy from fossil fuels and nuclear fuels to generate electrical power. Systems of this kind require multiple steps or processes in which energy undergoes a whole series of transformations through various intermediate forms.

Many of the energy converters widely used today involve the transformation of thermal energy into electrical energy. The efficiency of such systems is, however, subject to fundamental limitations, as dictated by the laws of thermodynamics and other scientific principles. In recent years, considerable attention has been devoted to certain direct energy-conversion devices, notably solar cells and fuel cells, that bypass the intermediate step of conversion to heat energy in electrical power generation.

This article traces the development of energy-conversion technology , highlighting not only conventional systems but also alternative and experimental converters with considerable potential. It delineates their distinctive features, basic principles of operation, major types, and key applications. For a discussion of the laws of thermodynamics and their impact on system design and performance, see thermodynamics. Energy is usually and most simply defined as the equivalent of or capacity for doing work.

The energy in a system may be only partly available for use. This means that the greater the mass or the distance through which it is moved or the less the time taken to move the mass, the greater will be the work done, or the greater the energy expended. The term energy was not applied as a measure of the ability to do work until rather late in the development of the science of mechanics.

Indeed, the development of classical mechanics may be carried out without recourse to the concept of energy. The idea of energy, however, goes back at least to Galileo in the 17th century. He recognized that, when a weight is lifted with a pulley system, the force applied multiplied by the distance through which that force must be applied a product called, by definition, the work remains constant even though either factor may vary.

The concept of vis viva, or living force, a quantity directly proportional to the product of the mass and the square of the velocity, was introduced in the 17th century. In the 19th century the term energy was applied to the concept of the vis viva. It is almost inevitable that the integrated effect of the force acting on the mass would then be of interest. Of course, there are two kinds of integral of the effect of the force acting on the mass that can be defined.

One is the integral of the force acting along the line of action of the force, or the spatial integral of the force; the other is the integral of the force over the time of its action on the mass, or the temporal integral. Evaluation of the spatial integral leads to a quantity that is now taken to represent the change in kinetic energy of the mass resulting from the action of the force and is just one-half the vis viva.

On the other hand, the temporal integration leads to the evaluation of the change in momentum of the mass resulting from the action of the force. To recapitulate, force is associated with the acceleration of a mass; kinetic energy, or energy resulting from motion , is the result of the spatial integration of a force acting on a mass; momentum is the result of the temporal integration of the force acting on a mass; and energy is a measure of the capacity to do work. It might be added that power is defined as the time rate at which energy is transferred to a mass as a force acts on it, or through transmission lines from the electrical generator to the consumer.

Conservation of energy see below was independently recognized by many scientists in the first half of the 19th century. The conservation of energy as kinetic, potential, and elastic energy in a closed system under the assumption of no friction has proved to be a valid and useful tool. Joule also proved experimentally the relationship between mechanical and heat energy at this time. As more detailed descriptions of the various processes in nature became necessary, the approach was to seek rational theories or models for the processes that allow a quantitative measure of the energy change in the process and then to include it and its attendant energy balance within the system of interest, subject to the overall need for the conservation of energy.

This approach has worked for the chemical energy in the molecules of fuel and oxidizer liberated by their burning in an engine to produce heat energy that subsequently is converted to mechanical energy to run a machine; it has also worked for the conversion of nuclear mass into energy in the nuclear fusion and nuclear fission processes.

As the global energy storage industry continues its path of rapid growth and technological innovation, power conversion systems PCS are emerging as a key enabling technology to facilitate optimal grid integration. Much of the industry focus over the past several years has been on battery technology, with significant decreases in prices and improvements in technical capabilities. Today, the industry is approaching maturity in some markets, and the focus is shifting from battery hardware to the other components of an energy storage system ESS , specifically the balance of system BOS and PCS. While batteries are becoming more standardized commodity products, PCS and inverters serve increasingly advanced system management and grid interaction functions. Several technological innovations have been introduced recently in the energy storage PCS industry that will allow for the more widespread use of energy storage on the grid.

A power station , also referred to as a power plant and sometimes generating station or generating plant , is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators , a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal , oil , and natural gas to generate electricity. Cleaner energy sources include nuclear power , and an increasing use of renewables such as solar , wind , wave and hydroelectric. In , a hydroelectric power station was designed and built by Lord Armstrong at Cragside , England. It used water from lakes on his estate to power Siemens dynamos.

What are the different types of power plants used to generate energy?

The electricity grid is a complex and incredibly important system, and one of the most impressive engineering feats of the modern era. It transmits power generated at a variety of facilities and distributes it to end users, often over long distances. It provides electricity to buildings, industrial facilities, schools, and homes. And it does so every minute of every day, year-round. A variety of facilities generate electricity, including coal- and natural gas-burning power plants, hydroelectric dams, nuclear power plants, wind turbines, and solar panels. The location of these electricity generators — and their distance from end users — varies widely.

Innovations in Power Conversion Technology for Grid Storage

The smokestack at Intermountain Power Plant looms mightily over rural Utah, belching steam and pollution across a landscape of alfalfa fields and desert shrub near the banks of the Sevier River. Five hundred miles away, Los Angeles is trying to lead the world in fighting climate change. But when Angelenos flip a light switch or charge an electric vehicle, some of the energy may come from Intermountain, where coal is burned in a raging furnace at the foot of the foot smokestack. The coal plant has been L. But Los Angeles is preparing to build a natural gas-fired power plant at the Intermountain site, even as it works to shut down three gas plants in its own backyard. Although gas burns more cleanly than coal, it still traps heat in the atmosphere.
