Cutting-edge quantum-technology backed green hydrogen production unveiled to power a green future
What is Cutting-edge quantum-technology backed green hydrogen production?
The state-of-the-art photochemical-reactor design features built-in illumination assembly and external concave reflective panels to maximize the capture of solar energy. The team has engineered a continuous electron coupled proton supply system, propelled with an electron injector mechanism utilizing industrial metal-waste, and after rigorous optimizations, the peak rate of Green Hydrogen production at lab scale was achieved to be about 1 litre/min per 10g of Quantum Photocatalysts.
The technology developed by the Green Keplerate Team from Banaras Hindu University. They introduced next-generation quantum-powered photo-catalyst with a charge transfer system coupled with high proton availability and mobility, and delivered quantum catalytic applications for energy generation.
Due to the high purity of the hydrogen gas produced, the fuel can be used without additional purification, thus enhancing the cost-effectiveness of the technology. This transformative innovation would offer wide ranging application possibilities across various sectors ranging from energy production to applications in transportation and agriculture.
The Green Keplerate Team have envisaged storage free direct hydrogen internal combustion engine technologies and have also demonstrated the same onto automobiles of varied range of engine/cylinder capacities and functionalities as a part of this ongoing project funded by the DST.
What is Green hydrogen?
Green hydrogen is a type of hydrogen that is produced through the electrolysis of water using renewable energy sources such as solar or wind power.
There are several ways to produce Hydrogen on industrial scale (large-scale). These include steam reforming of natural gas, oil reforming, or coal gasification. A small percentage is also produced using more energy-intensive methods such as the electrolysis of water. The hydrogen produced via these methods have been given various different names in order to distinguish them in terms of their carbon footprints.
Grey Hydrogen is traditionally produced from methane (CH4), split with steam into carbon-dioxide (CO2, Green House Gas) and hydrogen. Grey hydrogen is increasingly being produced from coal, with significantly higher CO2 emissions per unit of hydrogen produced. It is produced at industrial scale today. It has no energy transition value.
