Storing of excess Renewable energy

Storing of excess Renewable energy 
    
     A Finnish town is transitioning away from fossil fuels for district heating using a large sand-filled energy storage tank called a "sand battery". 
       This innovative system, developed by Polar Night Energy, stores excess renewable energy as heat and can be used to warm homes and businesses. 
 Detailed are as under:

The "Sand Battery":-
  The system uses crushed soapstone to store heat, allowing for efficient and sustainable heating. 

Location:-
   The sand battery is in operation in Pornainen, a town about an hour north of Helsinki, Finland. 

District Heating:-
  The sand battery will be used to replace natural gas and oil in the town's district heating network. 

Benefits:-
    The project is expected to reduce annual CO₂-equivalent emissions by around 160 tons, a 70% reduction in the town's district heating emissions, according to Polar Night Energy. 

Scale:-
    The sand battery is designed to deliver 1 MW of thermal power with a storage capacity of 100 MWh, making it ten times larger than previous sand batteries. 

Transition:-
    The use of oil in the town's heating network will be completely phased out, and wood chip consumption will decrease by approximately 60%, according to Polar Night Energy.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.
