What does green hydrogen mean?
The term “green hydrogen market” refers to the worldwide market for hydrogen gas generated by electrolysis, a process that makes use of renewable energy sources like solar or wind power. Unlike typical hydrogen production techniques that rely on fossil fuels, green hydrogen is created by splitting water molecules into hydrogen and oxygen atoms, producing only pure water vapour as a byproduct. Green hydrogen has gained a lot of interest due to its promise as a clean and sustainable energy source with applications in power production, energy storage, transportation, and industrial operations. The market encompasses the production, delivery, and use of green hydrogen in addition to associated technologies and infrastructure.
Fundamentals of green hydrogen market
- Expanding the use of renewable energy – The creation of green hydrogen requires a steady and plentiful supply of power, which is being supplied by the fast increase of renewable energy sources like solar and wind. Green hydrogen is becoming more accessible and more reasonably priced, which is fueling the market’s expansion as renewable energy capacity keeps growing.
- Growing global government support and policy incentives: To encourage the development and use of green hydrogen, governments everywhere are putting supporting laws, rules, and financial incentives into place. These policies, which provide a supportive atmosphere for the expansion of the green hydrogen industry, include grants, tax breaks, subsidies, and renewable energy objectives.
- escalating demand in industries of end use The market for green hydrogen is being driven by the growing need for sustainable and clean energy solutions in industries including power generation, transportation, and chemical manufacturing. Green hydrogen has a wide range of uses in many sectors as a fuel, feedstock, and energy carrier.
