Due to the strength of the caisson and the pressure it can withstand safely, it can be placed below a depth of 300 meters, anywhere relatively flat.

And such a caisson structure, the same gas storage space, the deeper the pressure, the greater the gas storage capacity.

At a depth of more than 200 meters, the pressure of more than 20 atmospheres is enough to increase the gas storage capacity of the caisson by more than 20 times.

At a depth close to the thermostat, the water temperature is basically around 10 degrees Celsius, which is nearly 20 degrees Celsius lower than the surface water temperature.

This temperature difference results in better performance for compressed air energy storage, and lower temperatures allow air to be compressed more easily, thus saving energy.

After the caisson was placed in place, before connecting the pipeline to prepare for gas storage, Wei Minsheng got a large amount of earth and stone through the shared space and filled it in the fence above the caisson.

The presence of these earth and rocks is enough to ensure that the caisson will not float and shake after it is fully stored.

A total of eight high-pressure exhaust pipes are provided by the four caissons, which can drive up to eight turbine generator sets at the same time, bringing the maximum capacity of the storage station to 240 megawatts, which is sufficient to meet all future electricity needs in Tuvalu.

In order to reduce the impact of noise from power generation equipment on urban residents, Wei Minsheng set up the construction site of the storage power station on the protective embankment where many water wheels were installed.

The distance of 200 meters can completely control the noise of the power station below the sound intensity of the waves, so that the residents living in the City of Hope will not be affected.

After the compressed air storage power station is repaired, all unstable energy sources such as tidal energy, wind energy, solar energy, and wave energy can be converted into compressed air through four high-pressure pipelines and stored, and then generated according to the electricity demand of the cities in the special zone.

The storage power station cannot be built in a day or two, and the four sets of caissons are not so easy to install.

However, this kind of combined power generation equipment can complete the operation of one group and put into one group.

According to the current scale and construction progress of the Special Economic Zone, a 30-megawatt generating unit is enough to meet all the current electricity demand.

In order to avoid wasting power resources during the trough of electricity consumption, Wei Minsheng added two 10-megawatt generating units to the storage power station.

With these two units, the storage power station can flexibly choose more than 10 MW, 20 MW and 30 MW according to the power consumption of different time periods, and any one interval is 10 MW of power generation to minimize power waste.

The first equipment to feed compressed air was the wooden water wheels installed on the embankment.

Although the power of each water wheel is not large, it is affected by the frequent changes in the size of the water flow in the culvert.

However, Wei Minsheng installed a gravity buffer accumulator at the power output end of the water wheel, which can achieve a stable and continuous power output of 5,000 watts.

With this structure, ten water wheels can reach 1,200 kilowatt-hours of electricity per day.

The second source of energy is wave energy, and countless concrete fixed piles are densely built on the edge of the breakwater.

On each fixed pile, a log with a diameter of 20 centimeters and a length of 5 meters is fixed with a wooden bolt, and the log can be shaken up and down with the wooden bolt as a fulcrum.

At the other end of the log, a pontoon was fixed.

Under the action of the pontoon, the kinetic energy of the waves is converted into the mechanical force of the log swinging up and down.

Then, using the principle of lever, the piston compressor is driven to work, and the compressed air produced is transmitted through a unified pipeline.

In addition to generating compressed air, these logs can also effectively reduce the force of waves on the embankment.

Although the number of logs on the breakwater is large, the amount of energy collected is also quite large.

However, due to the performance limitations of the piston compressor, it cannot generate high pressure, and it cannot directly press these compressed air into the submarine energy storage field of more than 200 meters.

Therefore, Wei Minsheng added a small caisson on the seabed at a depth of 60 to 70 meters for the transition from low-pressure gas to high-pressure gas.

Compressed air at seven or eight atmospheres can be easily pressed into the chamber of this small caisson.

The one-way valve of the inflation port can ensure that the air in the caisson will not leak along the inflation pipe when the equipment is overhauled.

At the top of the gas storage chamber of the caisson, a high-pressure compressor is fixedly installed, and the compressed air with a pressure of seven or eight atmospheres is pressurized to more than 20 atmospheres again by doing work again, and is sent to the high-pressure storage field through the high-pressure gas pipe.

In order to ensure the safety of the compressor, a number of water level detection switches are set under the compressor.

As soon as there is a switch action, the power to the compressor will be automatically cut off immediately and automatically on the shore.

In order to facilitate access, a gap is left at the bottom of the caisson to facilitate the entry and exit of maintenance personnel, or to serve as a replacement channel for the compressor.

Of course, the logs came from the other world, and the human resources and equipment there were used to process them into uniform sizes.

Although logs are not as strong as steel, they are more easily damaged when hit by storms at sea.

But it will not be eroded by seawater, and its damage can protect the safety of the equipment connected to it, which acts as a fuse.

In addition, these logs that are not seriously damaged can be repaired with a riveting falcon structure without affecting the use at all.

Leftovers from serious damage and repairs can also be used as fuel for centralized kitchens or gas generators under the influence of gasifiers.

Not much compressed air is produced per log, but the amount of it makes up for it.

Moreover, the waves that barely stop give endless green energy, which is not available in other energy sources.

Looking down from the sky, the waves inside and outside the breakwater are completely two worlds, and the surging waves become no longer violent after touching the cilia-like log energy harvesters on the breakwater.

Even when advancing to the breakwater, the force of the lapping of the embankment could not even turn a few large waves.

The relatively calm tidal reservoir in the breakwater made Wei Minsheng think about the use of solar energy.

The overall cost of a solar power system, which converts solar energy directly into electricity, is too high, and the power generation efficiency is not high.

Therefore, Wei Minsheng still uses an efficient concentrating method like an offshore platform to convert solar energy into high-temperature oil.

But these high-temperature fluids are used differently.

The compressed air will absorb a large amount of heat energy during the decompression process, in order to make the compressed air play a greater efficiency, the traditional way is to use compressed air and gas to drive the air wheel turbine.

Since some of the energy comes from the heat in the environment, the energy stored with compressed air can often be more than 100% energy efficient.

This does not violate the conservation of energy, but the energy absorbed from the environment during the decompression process also participates in the energy output, but people don't realize it.
