Increasing adoption of hydrogen and awareness toward importance of energy conservation are expected to boost the global market for hydrogen generation by 2025. Rising efforts to shift focus from fossil fuels to renewable fuels is expected to further propel market expansion. Numerous countries are introducing stringent regulations to significantly reduce indiscriminate use of conventional fuels responsible for excessive greenhouse gas emissions.
 
Hydrogen is among the most abundantly available elements on earth and it plays an important role in agriculture, fertilizer and chemical manufacturing, and pharmaceutical production among others. Over the next two decades, hydrogen is expected to be on par with electricity as an effective energy carrier. It is safely derived from renewable sources of energy and is effective in reducing emissions.
 
The merchant segment includes both small and large dealers, wholesalers, and companies deriving hydrogen as an excess byproduct. In terms of volume, captive hydrogen is the fastest growing segment with a CAGR of 9.2%. Captive is defined as on-site hydrogen generation, which eliminates numerous problems linked to conveyance and distribution of hydrogen. Therefore, the market is expected to grow substantially in future.
 
In terms of application, the steam methane reforming segment accounted for 68.8% of the global hydrogen generation market volume in 2016. In this method, methane containing raw material like natural gas is heated at a temperature between 700°C to 1,000°C, which produces hydrogen as a by-product. The coal gasification technology segment is anticipated to expand at a steady CAGR over the forecast period. Gasification of coal is one of the processes applied to produce liquid fuels, power, hydrogen, and chemicals.
