Researchers in South Korea have developed a next-generation electrochemical system that simultaneously produces green hydrogen and valuable chemical feedstocks (like formate) using waste glycerol from biodiesel production. This innovation, developed by KIMS and UNIST, significantly boosts economic viability by replacing energy-intensive water electrolysis with a more efficient, lower-cost process.

Researchers in South Korea have developed a next-generation electrochemical system that simultaneously produces green hydrogen and valuable chemical feedstocks (like formate) using waste glycerol from biodiesel production.
 This innovation, developed by KIMS and UNIST, significantly boosts economic viability by replacing energy-intensive water electrolysis with a more efficient, lower-cost process. 

Key Details of the Breakthrough:
Process:-

 The system utilizes an anion exchange membrane water electrolysis (AEMWE), where the traditional, energy-intensive oxygen evolution reaction (OER) at the anode is replaced by the glycerol oxidation reaction (GOR).
Efficiency: -
The system achieves approximately 96% selectivity for the target chemical product (format).
Performance: -
Tested in a commercial-level 79
 cm 22 electrolyzer, it demonstrates a high current density of 110 mA/cm 22 at a low cell voltage of 1.31 V, making it highly efficient.
Sustainability: -
This technology converts bio-derived waste (glycerol) into high-value chemicals, enhancing the overall economics of green hydrogen production and supporting carbon neutrality.
Innovation:-
 It uses low-cost, non-precious copper-cobalt metal catalysts designed for large-scale applications. 
This development enables greener and cheaper hydrogen production while providing a practical way to manage waste glycerol from the biofuel industry.

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...
