Green hydrogen is produced by electrolysis of water using renewable energy sources such as wind or solar power. It can be used in fuel cells for transportation, as a clean energy source for industry, or for energy storage. Its production process does not emit any greenhouse gases, making it environmentally friendly.
Blue hydrogen is produced from natural gas by steam methane reforming, using carbon capture and storage (CCS) technology to reduce emissions. It can be used in industrial processes, transportation, and as a cleaner alternative to fossil fuels. While it still relies on fossil fuels, carbon capture mitigates its environmental impact.
Pink hydrogen is produced by electrolysis powered by nuclear energy. It can be used in a similar way to green hydrogen in fuel cells, industrial applications, and energy storage. This method offers a low-carbon alternative, leveraging the reliability and efficiency of nuclear power.
White hydrogen refers to naturally occurring hydrogen found in geological formations, often extracted through mining. Its use is still largely experimental, but it has potential applications in energy production and storage. As a natural resource, it could provide a sustainable source of hydrogen if economically viable.
