Hydrogen Process Automation: International Market Signals in August 2026
17 August 2026 · Market and technology overview
The international hydrogen market is shifting. Alongside large electrolysis projects, decentralised reformer-based plants, hydrogen-ready power stations and industrial testbeds are emerging. Artificial intelligence is also moving into the control room. This creates new process-automation requirements for flexible operation, functional safety, diagnostics and transparent operator support.
South Korea: Decentralised hydrogen production from biogas
Hyundai Motor Group opened an integrated waste-to-hydrogen plant in Cheongju in July 2026. Sewage-sludge biogas is upgraded to biomethane and then reacted with steam to produce hydrogen. The facility combines gas upgrading, hydrogen production, carbon capture, compression, storage and refuelling. Initial output is approximately 500 kilograms of hydrogen per day, with expansion to two tonnes per day planned by 2030.
From an automation perspective, the close interaction between these process stages is significant. Gas quality, steam ratio, reformer operation, carbon separation and compression must be controlled as one system. Hyundai is pursuing similar projects in Indonesia and Hong Kong, signalling a transferable plant concept adapted to local feedstocks and infrastructure. Source: Hyundai Motor Group
South Korea: Support is shifting towards cleaner hydrogen
South Korea announced 2026 auction volumes of 500 GWh for clean-hydrogen power and 930 GWh for general hydrogen power. These volumes are considerably below earlier plans, while coal-ammonia co-firing is no longer intended to qualify as clean hydrogen generation.
This increases pressure on projects based on conventional hydrogen. Plants using renewable electricity, biogenic feedstocks, carbon capture or demonstrably low emissions become more attractive. Automation systems will increasingly need to manage hybrid operating models as well as energy, emissions and origin data. Source: Korean Ministry of Climate and Energy
Singapore: Hydrogen-ready power becomes infrastructure
The 600 MW Keppel Sakra Cogen plant began commercial operation in May 2026. It can initially co-fire natural gas with up to 30 percent hydrogen and is designed for a future conversion to full hydrogen operation. Singapore is also procuring additional hydrogen-ready CCGT capacity: at least 600 MW for 2031 and up to two more units of the same minimum size for 2032.
Automation requirements include fuel switching and blending control, gas-quality measurement, burner management, emissions control and functional safety. The central challenge will be managing changing hydrogen concentrations without compromising availability or grid stability. Source: JTC/Keppel · Source: Energy Market Authority
Jurong Island: Industrial testbed for hydrogen and CCUS
The Low Carbon Technology Translational Testbed LCT3 is being established on Jurong Island. Companies and research organisations will be able to validate hydrogen and CCUS processes under realistic high-pressure and high-temperature conditions. Its modular plug-and-play design requires flexible automation, configurable protection functions and reliable experimental documentation. Source: JTC Singapore
AI in the control room: From analytics to operator support
Honeywell plans to make Experion Cognition commercially available in the third quarter of 2026. The platform combines process data and AI agents to identify deviations early and support operators in resolving them. According to the vendor, pilot applications predicted alarm incidents an average of five to ten minutes in advance.
Relevant hydrogen applications include reformer-temperature monitoring, PSA valve diagnostics, detection of unstable steam-to-carbon ratios and automated shift reporting. A clear boundary remains essential in safety-critical processes: AI may provide forecasts and recommendations, but uncontrolled models must not replace protection functions or approved operating logic.

Assessment
The most visible opportunities are no longer limited to new large-scale plants. Decentralised reformer systems, conversion of existing energy assets, modular pilot facilities and data-driven operational support are developing into markets of their own. Successful automation solutions must therefore combine process knowledge with modular software, secure integration and transparent diagnostics.
