Grey Chemical Hydrogen
The grey chemical hydrogen segment in the market is characterized by the production of hydrogen using fossil fuels such as coal or natural gas. This type of hydrogen production is known for its high carbon emissions, making it less environmentally friendly compared to other types such as blue and green hydrogen. Despite this drawback, grey chemical hydrogen still holds a significant share in the market due to its cost-effectiveness and established infrastructure.
Blue Chemical Hydrogen
Blue chemical hydrogen is produced through steam methane reforming (SMR) combined with carbon capture and storage (CCS) technology. This type of hydrogen production significantly reduces carbon emissions compared to grey hydrogen, making it a more sustainable option for industries looking to decrease their carbon footprint. The blue chemical hydrogen segment is expected to witness growth in the coming years as more companies prioritize sustainability and environmental regulations become stricter.
Green Chemical Hydrogen
Green chemical hydrogen is produced through electrolysis using renewable energy sources such as solar or wind power. This type of hydrogen production is considered the most environmentally friendly option as it does not produce any carbon emissions. However, the green chemical hydrogen segment faces challenges such as high production costs and limited infrastructure. Despite these challenges, the demand for green hydrogen is expected to increase as countries aim to achieve net-zero carbon emissions and invest in renewable energy technologies.
