Energy storage solution provided by PC1 Group

Definition of energy storage solutions

Energy storage solutions refer to technologies or systems that can store excess energy produced during times of low demand for later use during times of high demand. These solutions help to balance the supply and demand of energy and provide a reliable source of power.

Energy storage solutions are becoming increasingly important as more countries shift towards renewable energy sources such as solar and wind power. These sources of energy are intermittent, meaning they may not always be available when needed. Energy storage solutions can help to bridge this gap by storing excess energy for use during times of low supply. This helps to ensure a more consistent and reliable source of power. Additionally, energy storage solutions can help to reduce the need for fossil fuel-based power plants and promote a more sustainable energy future.

Types of energy storage solutions

Batteries

Batteries are a type of energy storage solution that converts chemical energy into electrical energy. They store energy in the form of chemical reactions that can be reversed to release the stored energy. Batteries are widely used for energy storage in various applications, from small-scale portable devices to large-scale grid-level systems.

There are several types of batteries that can be used for energy storage, including:

• Lithium-ion batteries: These are the most widely used batteries for energy storage. They are efficient, have a high energy density, and can provide high power output.
• Lead-acid batteries: These are one of the oldest and most common types of batteries. They are relatively inexpensive and can be easily recycled.
• Sodium-sulfur batteries: These batteries use molten sodium and sulfur as active materials. They have a high energy density and can store large amounts of energy.
• Flow batteries: These batteries use two electrolytes that are separated by a membrane. They can store large amounts of energy and can be recharged by replacing the electrolytes.

Pumped Hydroelectric Storage

Pumped hydroelectric storage is a type of energy storage that uses two reservoirs at different elevations to store energy. During times of low demand, excess energy is used to pump water from the lower reservoir to the higher reservoir. When energy is needed, the water is released from the higher reservoir and flows back down to the lower reservoir through a turbine, generating electricity.

During times of low demand, excess energy is used to pump water from the lower reservoir to the higher reservoir. This increases the potential energy of the water and stores it as gravitational potential energy. When energy is needed, the water is released from the higher reservoir and flows back down to the lower reservoir through a turbine, generating electricity.

Flywheels

Flywheels are a type of energy storage solution that stores kinetic energy in a spinning rotor. During times of excess energy, the rotor is accelerated to high speeds, storing energy as rotational energy. When energy is needed, the rotor is slowed down, releasing the stored energy as electrical energy.

Flywheels consist of a spinning rotor that is housed in a vacuum or gas environment to reduce friction. The rotor is connected to a motor/generator that converts the rotational energy into electrical energy. During times of excess energy, the motor accelerates the rotor to high speeds, storing energy as kinetic energy. When energy is needed, the motor/generator slows down the rotor, releasing the stored energy as electrical energy.

Thermal Energy Storage

Thermal energy storage is a type of energy storage that stores heat or cold energy for later use. Thermal energy can be stored in various forms, including hot water, ice, molten salt, and phase-change materials. During times of excess energy, the thermal energy is stored for later use. When energy is needed, the stored thermal energy is released to generate electricity or provide heating/cooling.

Thermal energy storage works by storing thermal energy in a medium, such as water, salt, or a phase change material. The thermal energy is typically collected during times of excess energy and stored in insulated containers or tanks. When energy is needed, the stored thermal energy is released and used to generate electricity or provide heating/cooling.

Capacitors

Capacitors are a type of energy storage solution that stores energy in an electric field. They consist of two conductive plates that are separated by a non-conductive material, or dielectric. When a voltage is applied to the plates, an electric field is created, storing energy as electric potential.

Capacitors work by storing energy in an electric field between two conductive plates. During times of excess energy, the capacitor is charged, storing energy as electric potential. When energy is needed, the stored energy is released by discharging the capacitor, generating electrical power.

PC1 Group’s energy storage solution

BESS (Battery Energy Storage System) is an energy storage technology that makes use of specially designed lithium-ion (Li-ion) batteries. The fundamental idea is that this stored energy can be used later. To balance energy production and consumption, these systems supplement energy sources such as solar and wind power.

Our energy storage systems work well in conjunction with power sources that are affected by environmental conditions and interruptions, such as wind and solar. When there is wind and sunlight, excess energy is stored rather than fed back into the grid. When the wind dies down and the sun sets, that energy will be used instead of grid electricity.
