The expansion of the captive hydrogen generation market is driven by the increasing need for reliable, continuous, and cost-efficient hydrogen supply across industries such as refining, chemicals, steel, and ammonia production. As hydrogen demand rises, companies are investing in on-site production systems to reduce dependency on external suppliers and mitigate supply chain risks.
TRENDS & DISRUPTIONS IMPACTING CUSTOMERS' CUSTOMERS
With the growing emphasis on reducing carbon emissions, hydrogen generation companies have been shifting their focus toward producing low-carbon or zero-carbon hydrogen from conventional hydrogen fuel to reduce their carbon footprint. Hydrogen generation companies increasingly adopt electrolysis technology or technologies such as steam methane reforming, partial oxidation, and auto thermal reforming with carbon capture to produce green hydrogen. The companies diversify their business portfolio from traditional power generation to power generation through renewables. The hydrogen generation market is undergoing a significant transformation driven by the rapid shift toward low-carbon and renewable hydrogen production methods, particularly electrolysis powered by solar and wind. Declining renewable energy costs, government incentives, and global net-zero targets accelerate this transition. Traditional methods, including steam methane reforming (SMR), face growing pressure due to carbon emissions, while emerging technologies, such as methane pyrolysis and biomass gasification, are gaining traction.

Driver: Enforcement of stringent regulations to curb greenhouse gas emissions
Greenhouse gases (GHGs) absorb infrared radiation (heat energy) emitted from the Earth’s surface and re-radiate it, contributing to global warming. The continued rise in global GHG emissions is largely driven by rapid industrialization and heavy dependence on fossil fuels. According to the International Energy Agency (IEA), total energy-related CO2 emissions increased by 0.8% in 2024, reaching a record high of 37.8 gigatons (Gt). This contributed to atmospheric CO2 concentrations rising to 422.5 parts per million (ppm), which is approximately 3 ppm higher than in 2023 and 50% above pre-industrial levels.
Restraint: Energy loss during hydrogen production
Hydrogen is a synthetic energy carrier. It transports energy produced by various other processes. Water electrolysis converts electrical energy into hydrogen. However, in addition to producing hydrogen, high-grade electrical energy is also utilized to compress, liquefy, transport, transfer, or store the medium. Energy is needed for hydrogen production. The energy input should ideally match the energy level of the synthetic gas. Any method of producing hydrogen, such as electrolysis and reforming, involves energy transformation. The chemical energy of hydrogen is converted from electrical energy or the chemical energy of hydrocarbons. Unfortunately, energy losses are always a part of the creation of hydrogen.
Opportunity: Rising emphasis on achieving net-zero carbon emission targets
Hydrogen production goes through an unprecedented revolution under the net-zero emissions scenario. When the global output reaches 200 Mt H2 in 2030, low-carbon technologies will account for 70% of that production (electrolysis). By 2050, the amount of hydrogen produced will increase to about 500 Mt H2, almost entirely due to the implementation of low-carbon technology policies. Different technologies will be needed to alter the energy system to achieve net-zero emissions by 2050. Energy efficiency, behavioral modification, electrification, renewable energy, hydrogen and hydrogen-based fuels, and carbon capture, utilization, and storage (CCUS) are likely to play major roles in decarbonizing the energy system globally.
Challenges: High costs associated with renewable hydrogen production
Green hydrogen, produced using renewable energy sources or other low-carbon power, is increasingly recognized as a cornerstone for achieving deep decarbonization across energy-intensive and hard-to-abate sectors. Industries such as steel, cement, chemicals, heavy-duty transportation, shipping, and aviation can leverage green hydrogen to reduce carbon footprints and align with global net-zero targets significantly. Despite its environmental benefits, the commercial viability of green hydrogen remains a major challenge. Green hydrogen costs approximately two to four times higher than gray hydrogen, which is derived from fossil fuels without carbon capture. Several factors contribute to this disparity, including the high capital expenditure required for electrolyzer systems, the limited and uneven availability of low-cost renewable electricity, and the underdeveloped infrastructure for hydrogen production, storage, and distribution. These economic and logistical hurdles continue to hinder the widespread adoption of green hydrogen and restrict its contribution to the global energy transition.
CAPTIVE HYDROGEN GENERATION MARKET: COMMERCIAL USE CASES ACROSS INDUSTRIES
| COMPANY | USE CASE DESCRIPTION | BENEFITS |
|---|---|---|
 |
The steel industry is one of the most carbon-intensive sectors, contributing around 7–9% of global CO2 emissions. Traditional steel manufacturing uses coal-based blast furnaces. SSAB, a leading Swedish steelmaker, aimed to decarbonize its operations but faced challenges sourcing reliable, large-scale green hydrogen for hydrogen-based Direct Reduced Iron (DRI) technology. | SSAB, in collaboration with Vattenfall and LKAB, initiated the Hydrogen Breakthrough Ironmaking Technology (HYBRIT) project to revolutionize steel manufacturing by replacing coal with green hydrogen. The initiative features a 4.5 MW pilot electrolyzer powered by renewable electricity to produce fossil-free hydrogen for use in the iron and steelmaking process. The pilot plant successfully demonstrated the feasibility of fossil-free steel production and is progressing toward full-scale commercial deployment. Upon completion, the HYBRIT technology can potentially reduce Sweden’s total CO2 emissions by approximately 10%, representing a significant step toward decarbonizing one of the country’s most emission-intensive industries. |

Energy utility company, RWE (Germany), set the goal to produce large-scale hydrogen for its Lingen site in Lower Saxony, Germany. As part of the TansHyDE project, GET H2 Nucleus, RWE tested various electrolysis technologies, including Sunfire’s (Germany) highly efficient high-temperature electrolysis. | Initially, Sunfire delivered a 250 kW (kilowatt) system to Lingen. This high-temperature electrolyzer system will generate green hydrogen directly into RWE’s test pipeline at the power plant. As an additional pilot plant, Sunfire installed a 10 MW pressurized alkaline electrolyzer at RWE’s site in Lingen. The commercial project provides valuable insights into green hydrogen production on an industrial scale for both partners. |
