Comprehensive Green Hydrogen Market Growth Outlook 2025-2034: Trends, Forecasts, and Market Size Insights

The Business Research Company’s report on the Green Hydrogen Market provides insights into the global market size, growth rate, regional distribution, competitive landscape, key segments, emerging trends, and strategic opportunities.

How have key drivers contributed to the rapid growth of the green hydrogen market?
The increasing environmental concerns are expected to propel the growth of the green hydrogen market in the forecast period. Green hydrogen is a hydrogen-based fuel that is made by electrolyzing water with electricity supplied by low-carbon sources. It will help in reducing carbon emissions and provide care to our planet. For instance, the International Energy Agency (IEA) aims to bring global energy-related carbon dioxide emissions to net zero by 2050. Fossil fuels are one of the main contributors to poor air quality and they account for 80% of all the energy worldwide. Additionally, IEA estimates that by 2050 around 1.77 million premature deaths will occur due to indoor air pollution, and around 4.97 million premature deaths will occur due to outdoor air pollution. According to the World Health Organization, an estimated 4.2 to 7 million people die from air pollution worldwide every year, and nine out of ten people breathe air that contains high levels of pollutants. Therefore, increasing environmental concerns drive the growth of the green hydrogen market.
