The chemical industry accounts for roughly 10 % of global CO2 emissions, largely due to reliance on fossil‑derived hydrogen for processes like ammonia synthesis and methanol production. Green hydrogen offers a pathway to dramatically cut these emissions while maintaining product quality.
Key Chemical Processes Benefiting from Hydrogen
1. Ammonia Production – Traditionally uses steam reforming of natural gas. Green hydrogen can supply the required H2 directly to the Haber‑Bosch reactor.
2. Methanol Synthesis – Combines CO₂ with hydrogen; using renewable hydrogen creates carbon‑negative methanol.
3. Refinery Hydrotreating – Replaces conventional hydrogen in desulfurisation and denitrogenation.
Economic Advantages
- Reduced carbon pricing exposure as governments impose stricter emissions regulations.
- Potential premium pricing for low‑carbon chemicals in green markets.
- Improved ESG ratings, attracting sustainable investment.
Technical Considerations
When integrating green hydrogen:
- Ensure hydrogen purity meets >99.999 % specifications for catalyst protection.
- Assess existing reformer retrofits versus new electrolyser installations.
- Implement robust safety systems, especially for high‑pressure storage.
Policy Landscape
Many regions have introduced carbon‑border adjustment mechanisms (CBAM) that will penalise high‑carbon inputs. Early adopters of green hydrogen can avoid these penalties and gain market advantage.
Success Highlight: Green Ammonia Plant in Rotterdam
INFENER partnered with a major fertilizer producer to build a 10 MW electrolyser feeding a 150 kt/year green ammonia line. The plant achieved a 65 % reduction in CO2 emissions compared to the conventional process.
Implementation Roadmap
- Stage 1 – Audit – Map hydrogen demand across all processes.
- Stage 2 – Pilot – Install a modular electrolyser for a single unit operation.
- Stage 3 – Scale‑Up – Expand electrolyser capacity and integrate storage.
- Stage 4 – Optimization – Use data analytics to improve efficiency and lower operating costs.
