“It is a way to give these sites a new life.”

Energy creators around the world plan to harvest more energy from abandoned charcoal mines, but not by digging dirty deposits.

Instead, this concept is used as gravitational and renewable energy to convert collapsed sites to power sites from the next generation, according to reports from Causes of joy and Folk mechanics.

The method is somewhat simple. An excess of renewable energy is located that raises weights, which, in this case, is located in the shafts of old mines. The largest suspended part is the stored energy, which is very important to use sunlight or wind energy at night and when the breeze is slow. It is a process similar to the so -called water batteries, as it sends water regeneration pumps to the tank as stored energy. In both cases, the weight or water is dropped or released in a lower tank, and the generation of electricity, according to reports and a description From the World Economic Forum.

“This approach not only gives these abandoned mines a second life, but also provides economic and environmental benefits for societies that once depend on coal,” RTBC books.

As the world Transformations To clean energy sources – it is now represented 29 % From a generation around the world, according to the United Nations – storage has become a greater obstacle.

Lithium ion batteries such as Megapacks in Tesla or the giant sodium ion unit that stores energy in China is among other options. But these units require expensive and difficult materials to build or, at this stage of development, come with other logistical challenges. Sustainability was estimated in numbers that tens of millions of tons of deposits will need to be harvested to maintain the transformation of energy by 2040, and many of them are for batteries. But this is much lower than 16.5 billion Tons of dirty fuel surrounded by heat are pulled from the ground annually, according to the report.

Gravity batteries can be a cleaner bridge than our energy dirt to a sustainable future, and a key to avoiding The worst scenarios The result of our warming world. Increased risks to harsh weather and forest fires are among the changes that are already feeling. per NASA.

In the United States, there are 550,000 deserted mines, representing lost functions and causing environmental risks, according to RTBC And other reports. The abandoned shafts and more inactive industrial sites can become clean energy centers, with the potential for solar power installation sufficient to operate 200 million American homes annually, according to the story.

RTBC Add The mine-based gravity battery already provides enough energy to operate nine homes for a year in China-all with a suspended weight. Projects in Australia, Switzerland and Finland are also under development.

“Several mines have been closed in the 1980s and 1990s, and while environmental issues remain, using these sites to create a new energy that brings a sense of continuity.” He said In the RTBC report.

Among the challenges are harmful substances in old mines such as asbestos that sometimes need to be mitigated, and the process can be expensive, for each condition. But the appropriate investment and approach can turn them into a large hat if it is developed successfully.

“It is a way to give these sites a new life while respecting history and local heritage,” MCDERMOTTT He said In the story.

What is more, Tax exemptions It is still available to Add solar energy At home, it is possible that you will provide you with a step of up to $ 700 annually, even after expenditures, per Government study. Adding a small home battery can expand financial benefits.
