Energy Transition
Green hydrogen and ammonia delivered with process, power, and industrial EPC discipline.
Chemie-Tech supports utility-scale hydrogen and ammonia programmes through FEL, FEED, and EPC or defined-scope EPC delivery, bringing high-voltage integration, process safety, and modular execution into emerging energy-transition assets.
Positioning
The same high-voltage power systems, hazardous area engineering, modular fabrication, and construction controls that underpin our terminal and refinery programmes transfer directly to green hydrogen and ammonia facilities. Chemie-Tech has completed FEL studies and FEED scopes for green hydrogen and ammonia programmes in the United States, and supported pre-development and FEED work for a green hydrogen and green ammonia project in Abu Dhabi with solar power integration: building practical experience in project definition, grid code compliance, and process safety for these emerging asset classes.
How We Engage
