Soil energy storage for winter cold storage and summer heat storage
There are several types of STES technology, covering a range of applications from single small buildings to community district heating networks. Generally, efficiency increases and the specific construction cost decreases with size. UTES (underground thermal energy storage), in which the storage medium may be geological strata ranging from earth or sand to solid bedrock, or aquifers. UTES technologies include: [PDF Version]
How many hydrogen storage tanks are needed for hydrogen energy storage
is a storage form whereby hydrogen gas is kept under pressures to increase the storage density. Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) are used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology. Car manufacturers including Honda and Nissan have been developing this solution. [PDF Version]
Alcohol injection pump energy storage device
The energy-saving water injection pump is a pressure-increase device. It can further increase the water injection pressure on the high-pressure wellhead based on the pressure of the water injection main line i. [PDF Version]FAQS about Alcohol injection pump energy storage device
What is energy-saving water injection pump?
The energy-saving water injection pump is used for oilfield-pressurized water injection. The key technology of the device is to control the left and right stroke of the piston through the mechanical reversing valve, thereby driving the plunger to raise the pressure. The whole device is relatively simple in structure and reliable in operation.
What are the parts of an energy-saving water injection pump?
The energy-saving water injection pump is mainly divided into two parts: mechanical reversing valve and double-acting plunger pump. Figure 2 shows the overall structure. Figure 3 shows the functional scheme of the mechanical reversing valve. The valve body includes a main inlet, a main outlet, two oil feed ports, and two oil return ports.
What is the energy-saving effect of a water injection pump?
The energy-saving effect of the energy-saving water injection pump is remarkable. The injection can be realized without introducing a high-power source using only a small power motor with a (1. 1, {text {kW}}) power to drive the mechanical directional control valve and a motor-driven hydraulic pump with a power of (1 1, {text {kW}}).
What are the structural parameters of the energy-saving water injection pump?
The structural parameters of the energy-saving water injection pump were determined. The finite element simulation of the piston cylinder and the plunger cylinder was performed, which shows that the structural strength meets the requirements. The hydraulic system dynamic simulation shows that the output pressure meets the water injection pressure.
Can a water injection device meet the injection pressure and power consumption requirements?
The output pressure and power consumption were recorded every day. The records are presented in Table 3. The data reveal that the device can meet the injection pressure and everyday water injection requirements of the two high-pressure wells and that the device is qualified for the injection task.
How a water injection pump works?
The water smoothly flows in the plunger, the pressure change is not steep, and the work condition is stable. After completing the design of the energy-saving water injection pump, the parts were processed and finally assembled according to the drawings, as shown in Fig. 14.
How does solar energy storage technology heat
Thermal energy storage (TES) refers to heat that is stored for later use—either to generate electricity on demand or for use in industrial processes. Concentrating solar-thermal power (CSP) plants utilize TES to increase flexibility so they can be used as “peaker” plants that supply electricity when demand is high; as. . TES helps address grid integration challenges related to the variability of solar energy. Storing thermal energy is less complicated and less expensive than storing electrical. . SETO research for TES and HTM primarily focuses on raising the temperature of the heat that can be stored, which will ultimately lower the cost of energy due to increased. . The kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commercially availabl. [PDF Version]
