Startup From Finland Developed New Sand Battery That Promises To Eliminate The Use Of Oil And Dramatically Reduce Pollutant Gas Emissions.

A large sand battery will eventually heat the municipality of Pornainen, Finland. The system is a type of thermal energy storage that uses sand. The expectation is that the technology can meet the heating demands of the region, moving away from the use of oil and significantly mitigating carbon emissions.

The project, which promises to end oil usage, is being developed by the startup Polar Night Energy, which plans to complete its construction in one year and one month. The sand battery uses the material as a heat conductor, storing it to later generate energy.

The system from Polar Night Energy is a bit different in this regard, as it replaces sand with crushed soapstone. The goal is to transform the excess energy produced by wind and solar sources into thermal energy through a process called resistive heating. This will heat the air, which will be conducted through heat transfer pipes to the crushed soapstone. This stored hot air can be used to heat homes in Finland during the winter.

Sand Battery Is More Affordable Than Oil

In contrast to several other environmentally harmful energy generation options, the sand battery from Finland represents a promising alternative. Besides being more affordable, it has a lower environmental impact and contributes to reducing climate change. Although there are still challenges, such as energy loss in thermal conversion, the economic and environmental potential of batteries is encouraging.

It is worth mentioning that Polar Night Energy was founded in 2016 by two young thermal energy specialists. The idea, which originated in the university environment, began to be applied in the real world when the duo partnered with the energy supplier Vatajankoski.

The startup gained support from the local government. The country is facing a fuel shortage due to rising gas prices. Russia cut off gas supplies to Finland for refusing to pay in rubles.

Innovations For Energy Generation

A scientific innovation may change the way we store energy. Researchers at the Chemical Energy and Environment Institute (IQUEMA) of the University of Córdoba (Spain) developed a battery that transforms chemical energy into electrical energy using hemoglobin.

Hemoglobin is present in the blood and is the protein responsible for transporting oxygen from the lungs to the tissues via red blood cells. Thus, it earns the nickname blood battery.

The researchers used zinc-air batteries, which combine atmospheric oxygen and the metal zinc in a liquid alkaline electrolyte, generating electricity with a byproduct of zinc oxide produced in the reaction. The prototype works as follows: Hemoglobin facilitates the electrochemical reaction known as the Oxygen Reduction Reaction (ORR).

Seen from space, an image taken by an astronaut shows an unlikely oasis in the Saudi Arabian desert, protected by a terrain that slows the advance of sand, surrounded by green circles, remnants of an extinct lake and nearly 10,000 years of preserved history.

While the U.S. still faces limitations in deep space, China is developing unprecedented technology with strategic satellites that maintain communication with the far side of the Moon and aims for dominance by 2030.

The oldest tree in the world, alive since before the birth of Jesus Christ, is cut down in a scientific study and the case changes environmental preservation rules.

An entire island in the Pacific wants to surround itself with a colossal barrier against the ocean to try to escape increasingly violent waves and not be swallowed by the sea in the coming decades.

With 7.4 trillion tons of artificial snow pumped in 10 years, an extreme operation could stabilize the West Antarctic ice sheet and prevent a sea level rise of more than 3 meters, but it would require snow cannons, ocean water, and energy on an almost industrial scale at the end of the world.

In the Saudi Arabian desert, the world’s largest green hydrogen plant is 80% complete and will use 4 gigawatts of solar and wind energy to produce 600 tons of clean fuel per day when it opens in 2027.

At a depth of 914 meters, a team accidentally discovers a pirate ship with cannons, a telescope, and objects from three continents on the seabed, uncovering a mystery that has haunted Europe for centuries.

Brazilian producers are leaving Roraima to plant in Guyana, where the government offers land on concession and does not charge taxes, while in Brazil the harvest faces high interest rates and a bureaucracy that hinders even the use of the rivers.

Instead of digging new holes, scientists dive into an abandoned acid mine lake in Montana and discover that the toxic water has already done the work of extracting rare earths from the rock on its own.

The photo that changed airport security worldwide was accidentally taken in Sydney in 1970, when a camera inadvertently captured the fall of a teenager from the landing gear of an airplane.

Argentina’s TV erupts and fires back: “the minister is selling us out to the Brazilians” after a snow campaign becomes the target of mockery.
