Kawasaki Heavy Industries Japan has launched the world's first commercial gas engine capable of operating on a 30% hydrogen blend (by volume). Released in late 2025, the KG series engine supports Japan's carbon neutrality goals by reducing CO2 emissions while using existing infrastructure, offering a, scalable, and practical transition to clean energy. 

Key Details of the Hydrogen Engine Breakthrough:
Technology & Efficiency:-
 The engine, developed by Kawasaki, uses a 30% hydrogen and 70% natural gas mix, maintaining high power generation efficiency while reducing CO2𝐢𝑂2 emissions by approximately 1,150 metric tons annually compared to natural gas-only models.
Commercial Availability:-
 Orders for the 30% hydrogen co-firing engines opened in September 2025 following successful validation tests at their Kobe works.
Infrastructure Friendly: -
The engine is designed to work with existing city gas pipelines, allowing for lower-cost adoption compared to pure hydrogen systems.
Versatility: -
The system is adaptable for distributed power sources and includes features for safety and flexible operation, such as adjusting the hydrogen ratio during use.
Broader Initiatives:-
 This development is part of a larger Japanese initiative to advance hydrogen technology, including marine engines and power generation, to achieve net-zero by 2050. 
This initiative marks a significant step in the,,, "Production, Transportation, Storage, and Utilization" of hydrogen energy in Japan. 
   Based on such technology and experience, this product is a hydrogen-ready model that can burn a mixture of up to 30% (by volume) hydrogen with natural gas.

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.
