Swedish scientists have proposed utilizing extra wind and solar energy to burn metals reminiscent of aluminum and iron, to generate warmth that can be utilized to generate electrical energy or hydrogen.
Researchers at Lund College in Sweden have developed a method to retailer electrical energy produced by wind and photo voltaic installations, by burning scrap metallic. The storage approach makes use of wind and photo voltaic electrical energy in electrical techniques that burn metallic energy, often iron or aluminum, and react with scorching air or steam.
“The warmth launched can be utilized to drive generators which in flip produce electrical energy“stated the scientists, saying that on the finish of this course of, the metallic oxide stays as a powder. “Alternatively, one can select to make hydrogen gasoline, the place combustion takes place in scorching steam.”
They stated that through the use of photo voltaic or wind energy, the oxidized powder will be turned again into abnormal metallic. Claimed that the method is secure, low cost and fossil-free.
“Utilizing electrolysis, metallic oxide will be transformed again to metallic,” the researchers stated. “This may be achieved by pouring metallic oxide powder into an answer containing cryolite the place two current-carrying electrodes are inserted to begin a chemical response.
The analysis group plans to construct a facility primarily based on the round technique of a brewery in southern Sweden, the place electrical energy manufacturing must be expanded. Their work builds on years of analysis efforts in burn metals reminiscent of iron and aluminum.
“The pilot plant will likely be like a small coal-fired energy plant, however the place coal is changed by iron,” stated researcher Marcus Aldén.
The crew hopes to copy the plan in different places in Sweden Area of Skåne.
“Along with some analysis teams in Germany, Canada and Holland, we concluded that these widespread metals are so good as an vitality supply and an vitality provider that they will act as a component of provide of vitality,” the lecturers stated. , with out offering additional technical particulars.
The researchers are probably referring to the Max-Planck-Institut für Eisenforschung in Germany and TU Eindhoven within the Netherlands, which printed a paper in Journal of Supplies in October to current an analogous expertise.
