In part 1 of a series on hydrogen in Europe, we cover hydrogen basics, its relevance, its various colors, and the impact of decarbonization regulation.
What is green hydrogen, blue hydrogen, and so on? Producing hydrogen takes energy because hydrogen atoms don't exist on their own — they are almost always stuck to another atom, often another element. (On earth, hydrogen is particularly abundant in the form of water, or H2O.) Creating pu...
Learn how India's National Green Hydrogen Mission can help you utilise green hydrogen as renewable energy and achieve your ESG goals.
In photosynthesis, what happens to the hydrogen ions (H+) after water is split in the light - reaction? A. They are released into the air B. They are combined with carbon dioxide in the dark - reaction C. They are used to generate ATP D. They are directly converted into glucose ...
What is renewable hydrogen? Renewable hydrogen is hydrogen derived from water. It’s created using a process called electrolysis, wherein electricity from renewable sources is used to split the hydrogen molecules from the oxygen molecules in water. Because the electricity used here comes from renewabl...
Hydrogenation is widely used in the industry. Hydrogenation is used to solidify, preserve or purify many products, raw materials, or ingredients. Ammonia, fuels (hydrocarbons), alcohols, pharmaceuticals, margarine, polyols, various polymers and chemicals (hydrogen chloride and hydrogen peroxide) are pro...
