Why did the once hopeful star lose hope?

Flammable ice, once considered the mainstream energy of the future more than 10 years ago, disappeared more than 10 years later. This is reallyHow fiercely it was blown back then, how tragically it has fallen now!

Combustible ice is not an ordinary ice block, but a natural gas hydrate that can burn. Due to the special environment, it takes on the appearance of ice blocks. According to current research findings,China's combustible ice reserves rank first in the worldThis has given China, which lacks oil and natural gas, hope for future energy. But what happened to combustible ice when it blew through the sky and now there's no movement?

The Energy of Sleeping at the Bottom of the Sea

To form combustible ice, it is necessary to have a low temperature and high pressure environment, and the one that meets this environment in the world is the bottom of the ocean.

After long-term accumulation and evolution, a lot of combustible gases have been formed in the crust, and most of them are extracted from land and shallow sea to become natural gasThe high-pressure and low-temperature environment deep in the ocean allows natural gas and water to combine together.

The crystalline compound of both becomes the combustible ice we see,The appearance looks like ice, but it can burn after ignition.Green energy.

According to scientists' estimates,Flammable ice reserves are 2-10 times the global natural gas reserves.

Huge reserves of clean energy, supported by two major buffs,Since 2010, combustible ice has become a focus of scientists' research,.

Through experiments, it was found that,1 volume of combustible ice can release 164 volumes of natural gas and 0.8 volumes of water.

In 2013, Japan became the first country to extract combustible ice from the seabed.Feeling Japan crossing the river.2017.

In subsequent resource censuses, scientists estimated that,..

The media back then also used this tone, advocatingCombustible ice is the future of humanity, providing clean energy that can be used for hundreds or thousands of years for the entire human race.

But later things didn't go as expected,Combustible ice has gradually disappeared instead of being extensively mined.

Although things are good, they are difficult to dig up

.Although things are useful, they are too difficult to dig up.

From the current technology perspective, adopting the former is basically unrealistic, and human technology cannot reach the height of mining on the seabed. MoreoverThe enormous energy density of combustible ice is like a block of bombs.

Disputes over environmental impacts

.

The geological structure of the seabed can be described as maintaining a fragile balance,Human beings dig combustible ice at the bottom of the sea, just like randomly extracting a piece from a built block.

.Intense geological activities are likely to bring catastrophic disasters to humanity.

.After burning for over 50 years, there is still no sign of extinguishing itThis is"Darvaza gas crater"!

..

.The extinction of marine organisms 183 million years agoScientists speculate that it may beSudden release of methane from the seabed, affecting the oxygen content of seawater.

Mining costs are too high

.Mining costs are too high.

.But the cost of mining has sharply increased.

More Renewable resource and less Renewable resource can not only ensure sustainable development of human beings, but also be responsible for future human beings!
