Solar Thermal Power for Electricity with Thermal Energy Storage

With the increasing trend towards cleaner and more sustainable energy sources, the use of solar thermal power has become a very attractive option. Solar thermal power provides a clean, renewable energy source, which can be used for both large and small scale applications. Solar thermal power can also be integrated with thermal energy storage, so that the electricity produced can be stored and used later on, when the sun isn’t shining or when the grid isn’t accessible.

If you’re looking for a new renewable energy source to power your home or business, this article will tell you everything you need to know about solar thermal power, including benefits, application-specific considerations, and more.

Key Facts About Solar Thermal Power

First off, let’s discuss some key facts about solar thermal power. The information below will give you a general idea of what solar thermal power is and the opportunities it provides.

Clean Energy Source

With the rise in popularity of renewable energy sources, many electricity suppliers have turned to solar thermal power as an eco-friendly and sustainable energy option. Photovoltaic (PV) devices use sunlight to generate electricity; however, they are still somewhat dependent on the energy of the sun. This can lead to fluctuations in their output, since the intensity of the sun’s rays changes throughout the day. On the other hand, solar thermal power provides a steady supply of electricity, since its source of energy is independent of the weather condition.

Another advantage of solar thermal power is its ability to produce up to twice as much electricity per unit compared to photovoltaic devices. This makes it a very cost-effective solution for applications where a large amount of power is needed. Additionally, solar thermal power does not require very high temperatures to operate, making it suitable for use with smaller, more efficient thermal energy storage units. This could make it a very attractive option for residential and light industrial uses, where space and weight are no object.

Multi-Functionality

Solar thermal power has several advantages, not just as an energy source but also as a way of storing energy. As mentioned above, thermal energy storage allows for greater output repeatability and more efficient use of power. If you’re looking for an energy source that can provide several functions, such as electricity and hot water (for heating applications), then solar thermal power is certainly a solution worth investigating.

Remote Location

One of the biggest issues with relying on electricity delivered by traditional energy companies is the fact that a lot of the power is generated at or close to the point of use. This makes it difficult for consumers to take advantage of cheaper electricity when available. With solar thermal power, this is not a problem, since the electricity can be generated at a remote location and transported to wherever it is needed. This makes it possible to take advantage of cheaper electricity whether it’s day or night, whatever the weather condition, and regardless of whether the sun is shining or the moon is hiding behind the clouds.

Additionally, transporting large amounts of electrical energy over long distances can be dangerous, due to the increased risk of energy loss or misdirection. This is why most electricity is generated close to where it is needed. However, with solar thermal power, electricity can be generated at a central location and distributed to individual consumers, who can then use it as needed. This makes it a much safer option and also allows for greater efficiency and reduced costs.

Resilience

PV devices and other types of renewable energy sources, such as wind and hydroelectricity, work best when conditions are optimal. However, when the wind isn’t blowing or the water isn’t flowing, the applications of these alternative energy sources reduce significantly. This makes them very dependant on external factors, which can cause frequent downtime and poor output quality. As a result, many people have turned to solar thermal power to provide them with a steady source of energy, regardless of the weather condition.

Since solar thermal power provides a continuous supply of electricity, it can be used to power homes, businesses, and other applications, where uninterrupted power flow is needed. Additionally, as discussed above, solar thermal power has the ability to store energy, which, when used, will provide greater resilience to fluctuations in the energy supply. This could make it a very attractive option for people who are prone to frequent blackouts or other types of power outages.

A Cool And Efficient Option

Another major advantage of solar thermal power over conventional electricity generation is its ability to maintain a constant temperature, regardless of the ambient conditions. For example, if you live in a cold climate where the temperature drops below freezing in the winter and you turn on the heaters in your house, then you’ll be consuming more electricity than usual to heat the home. However, with solar thermal power, the electricity used to heat the home will be offset by the electricity used to cool it, since the panels generate heat as well as electricity. This makes solar thermal power a very efficient option for people who need large amounts of power but can’t afford to have their electricity costs skyrocket due to unusual consumption.

What Is Thermal Energy Storage?

Thermal energy storage is the process of storing heat in some form, which can be used for later on, when the heat is needed. This can be done using a variety of methods, including using an inert material, such as carbon dioxide, to absorb heat and then storing it in liquid or solid form. As a result, thermal energy storage allows for greater output repeatability and more efficient use of power since the stored heat can be used over and over again. In order to regulate the temperature of the stored heat, some type of thermal energy storage unit must be used.

There are several different types of thermal energy storage units, which can be used to regulate the temperature of the stored heat. The most popular ones are the ones that use a working fluid, such as liquid sodium or a phase-changing refrigerant (PCR), to store heat. Let’s take a look at each of these in turn.

Liquid Sodium

One of the more popular methods of storing heat is with liquid sodium. Liquid sodium has several advantages, which make it a very attractive option for thermal energy storage. First of all, it is the most efficient method of storing heat. It also has the ability to absorb large amounts of heat before it changes phase, which makes it suitable for use with large-scale solar thermal power plants. Finally, it has the ability to conduct heat very well (better than most other types of working fluids), which allows for greater control over the temperature of the stored heat.

Advantages Of Liquid Sodium For Thermal Energy Storage

The above illustration (Figure 1) shows some of the advantages of liquid sodium as a working fluid for thermal energy storage. The liquid sodium in the upper left of the illustration is being used to regulate the temperature of a building, which in turn is providing them with hot water for heating purposes.

As you can see, liquid sodium has several advantages as a working fluid for thermal energy storage, which makes it a very popular choice among people who are looking to use renewable energy sources to power their homes and businesses. Since liquid sodium is so efficient at absorbing heat, it makes sense to incorporate it into your next thermal energy storage project.

PCR Refrigerant

Another method of storing heat that is gaining a lot of popularity is with phase-changing refrigerant (PCR) systems. PCR has several advantages, which makes it a very attractive option for storage. First of all, it can be used to regulate the temperature of a building or other location very precisely. This makes it a very popular choice among scientists, engineers, and other people who need to store a specific amount of heat for a particular purpose.

Secondly, PCR is lightweight; it weighs only a few pounds per unit, compared to some other, more popular types of thermal energy storage, that can weigh tons. This makes it easy to transport and handle, which could make it a safer option for homeowners and people who need to move large amounts of equipment and material around their property in order to set up or remove the system.
