Converting waste Styrofoam into a liquid organic hydrogen carrier (LOHC), which enables safe, reusable storage and transport of hydrogen at room temperature and pressure. The approach addresses polystyrene recycling challenges and provides a practical, reusable system for hydrogen storage by breaking down Styrofoam into aromatic compounds that chemically bind with hydrogen. Catalysts are used to facilitate hydrogen absorption from the Styrofoam-derived compounds and release it later for use.

   New process converts waste Styrofoam into a liquid organic hydrogen carrier (LOHC), which enables safe, reusable storage and transport of hydrogen at room temperature and pressure. 
  The approach addresses polystyrene recycling challenges and provides a practical, reusable system for hydrogen storage by breaking down Styrofoam into aromatic compounds that chemically bind with hydrogen. 
  Catalysts are used to facilitate hydrogen absorption from the Styrofoam-derived compounds and release it later for use. 

How the Process Works 
1) Decomposition:-
Waste Styrofoam is heated, causing it to decompose into low-molecular-weight aromatic compounds, such as styrene and toluene.
2) Hydrogen Absorption:-
  These aromatic compounds are then reacted with hydrogen at elevated temperatures, a process that utilizes a ruthenium catalyst to store the hydrogen within the compounds' chemical structure.
3) Hydrogen Release:-
  To release the stored hydrogen, the LOHC is passed over a different catalyst, typically platinum-supported, at high temperatures.
Key Advantages
Safe & Stable:-
The LOHC method allows for the storage of hydrogen in a stable, liquid state at room temperature and pressure, eliminating the need for high-pressure tanks or cryogenic temperatures. 
Reusable System:-
The process creates a closed-loop system where the original aromatic compounds can be regenerated and reused for subsequent hydrogen storage cycles, making it a reusable solution. 
Addresses Plastic Waste:-
The technology provides a new use for polystyrene waste, contributing to plastic recycling efforts. 
Leverages Existing Infrastructure:-
Because the LOHC is a liquid, it is compatible with existing oil transportation infrastructure, making it easier to integrate into the developing hydrogen economy.

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...
