Sand battery technology and other technologies under study
Sand batteries are a promising innovation, using sand as a thermal storage material to generate energy. Other technologies under study include flow batteries, supercapacitors and the use of organic materials for energy storage.
Sand battery: innovative system will heat Canada
A large “sand battery” will heat the city of Yellowknife, Canada, in the future. The system is a type of thermal energy storage that uses sand. The expectation is that the technology can meet the region’s heating demands, eliminating the use of oil and reducing carbon emissions. The project is being developed by the startup Northern Lights Energy, which plans to complete its construction in a year and a month.
How will this sand battery work?
The sand battery uses the material as a heat conductor, storing it for later generation of energy. Northern Lights Energy’s system is a bit different in this regard, as it replaces the sand with crushed soapstone. The idea is to convert excess electricity generated by wind and solar energy into thermal energy through a process called resistive heating. This heats the air, which is then passed through heat transfer tubes to the crushed soapstone. This stored hot air can then be used to heat Yellowknife homes during the winter.
Carbon Emission Reduction
Northern Lights Energy’s sand battery will be 13 meters tall and 15 meters wide, with a heating capacity of 1 megawatt and the capacity to store up to 100 megawatt-hours of thermal energy. This is enough to heat the entire Yellowknife region and, consequently, reduce the city’s carbon emissions. According to the startup, carbon dioxide emissions should be reduced by 70% with the use of the technology, since it will eliminate the need for oil and reduce the burning of wood waste, such as sawdust, by approximately 60%.
Cheaper alternative with less impact on the environment
In contrast to many environmentally harmful energy generation options, sand batteries represent a promising alternative. In addition to being more affordable, they have a lower environmental impact and contribute to the mitigation of climate change. Although there are still challenges, such as energy loss in thermal conversion, the economic and environmental potential of the batteries is encouraging.
Economic example and advantages for the consumer of adopting a battery system
A cost-effective example is the installation of a battery system in a home that uses solar energy. This can reduce the electricity bill by up to 70%, providing a return on investment in just a few years. In addition, consumers gain energy independence and contribute to the reduction of carbon emissions.
About electric cars
They offer several economic and environmental advantages that are important for both consumers and the environment. Let's explore these advantages:
Economic Advantages for the Consumer
Fuel Savings: Electric cars are more energy efficient. The cost per kilometer driven is significantly lower compared to combustion vehicles. This translates into substantial savings over time. Reduced Maintenance: Electric vehicles have fewer moving parts than combustion cars, which results in less wear and tear and, consequently, lower maintenance costs. There is no need for oil changes, and the brake systems last longer due to the use of regenerative braking.
Tax Incentives: Many governments offer tax incentives, rebates and subsidies for the purchase of electric vehicles. These incentives can significantly reduce the initial cost of ownership.
Environmental Benefits
Reduced Emissions: Electric cars do not emit polluting gases during operation, which helps reduce air pollution and greenhouse gas emissions. This is crucial to combating climate change and improving air quality in cities. Use of Renewable Energy: When charged with energy from renewable sources, such as solar or wind, electric cars can operate with a near-zero carbon footprint. This maximizes environmental benefits and promotes sustainability.
Reduced Noise Pollution: Electric cars are much quieter than combustion-powered vehicles, which contributes to reducing noise pollution in urban areas.
Economic Examples and Advantages
A practical example is the savings generated by owning an electric car compared to owning a combustion-powered car. Suppose a driver travels 15,000 km per year. With a combustion car, he would spend around R$7,500 on fuel, while with an electric car, the cost would be approximately R$1,500 on electricity. This results in an annual saving of R$6,000.
In addition, the reduction in maintenance costs can represent an additional saving of up to R$2,000 per year. With tax incentives, the initial cost of the electric vehicle can also be reduced, making it an even more attractive option.
Conclusion
Electric cars represent a significant change for both consumers and the environment. They offer an economical and sustainable solution for transportation, contributing to the reduction of pollutant gas emissions and promoting a greener and healthier future.
Electrification and the use of new technologies are just beginning and promise to shape a cleaner and more sustainable energy future.
