Importance of Green Hydrogen

Importance of Green Hydrogen 
   A new solar beam reactor technology, developed by Australian and Japanese researchers, offers a promising pathway to producing "green" hydrogen, a clean energy source, potentially at a lower cost than traditional methods like electrolysis. This innovation could revolutionize clean energy, particularly for industries where direct electrification is challenging. 
Here's a breakdown of the key aspects:

What is Green Hydrogen?
    Green hydrogen is produced using renewable energy sources, such as solar or wind power, to split water into hydrogen and oxygen through electrolysis. 

The Innovation: Solar Beam Reactor
Beam-Down Design:-
   Unlike traditional solar thermal systems that focus sunlight on a central tower, this new reactor design redirects solar energy to a ground-level receiver. 

Heliostats:-
   A field of heliostats (movable mirrors) focuses sunlight onto a tower-mounted reflector, which then beams the energy down to the receiver. 

High Efficiency:-
    This design enhances efficiency, safety, and accessibility, with early tests showing solar-to-hydrogen conversion exceeding 20%, surpassing the typical 15% achieved by other methods. 

Reduced Costs:-
  By potentially lowering the cost of green hydrogen production, this technology could make it a more competitive alternative to fossil fuels. 

Why Green Hydrogen?

Decarbonization:-
    Green hydrogen can be used to power industries that are difficult to electrify directly, such as heavy industry and transportation. 

Energy Security:-
   By producing hydrogen from domestic renewable sources, countries can reduce their reliance on imported fossil fuels. 

Grid Stability:-
   Green hydrogen can be stored and used to balance the intermittency of renewable energy sources like solar and wind, ensuring a more reliable energy supply. 

India's Green Hydrogen Mission: -

National Goal:-
   India has set a target to produce 5 million metric tonnes of green hydrogen annually by 2030.

Capacity Addition:-
 This requires a significant increase in renewable energy capacity to support green hydrogen production.

Investment:-
 The National Green Hydrogen Mission is expected to attract significant investments in green hydrogen production infrastructure.
In essence, the solar beam reactor offers a potentially more efficient and cost-effective way to produce green hydrogen, aligning with global efforts to transition to cleaner energy sources and achieve decarbonization goals.

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...

Lift off the ground during seismic activity, minimizing damage in Japan

Lift off the ground during seismic activity, minimizing damage in Japan     Japan has developed a technology that allows houses to literally lift off the ground during earthquakes, protecting them from damage.    This is achieved using a system of compressed air and sensors that inflate an airbag under the house, lifting it a few centimeters during tremors. The house then gently settles back down when the shaking stops.      Japan has developed innovative earthquake-resistant technology that allows houses to lift off the ground during seismic activity, minimizing damage. This is achieved through systems like the one developed by Air Danshin, which uses compressed air to lift houses on airbags. When sensors detect tremors, the airbag inflates, raising the house a few centimeters and preventing it from shaking violently with the ground.    More detailed explanation: Airbag Technology:- Air Danshin has pioneered the use of large airbags placed b...
