What's Happening?
The Korean Register (KR) has granted Approval in Principle (AIP) for the Hi-CLEARS ammonia-fueled ship safety solution, developed by HD Hyundai Heavy Industries and HD Korea Shipbuilding & Offshore Engineering. Announced at Gastech 2025, the system captures ammonia gas leaks, converts them into aqueous ammonia, and uses it in an SCR system, achieving 'Zero Discharge' of ammonia. This breakthrough technology addresses safety and regulatory barriers, laying the groundwork for future international standards for ammonia-fueled vessels.
Why It's Important?
The approval of Hi-CLEARS represents a significant advancement in the maritime industry's efforts to adopt eco-friendly technologies. By mitigating ammonia leakage and utilizing it for harmful gas treatment, the system enhances both safety and environmental compliance. This development is crucial for the commercialization of ammonia-fueled vessels, which are seen as a promising solution for reducing maritime emissions. The collaboration between KR and HD Hyundai strengthens the industry's global competitiveness and commitment to decarbonization.
What's Next?
Following the approval, KR and HD Hyundai will focus on refining technical rules and requirements to support the commercialization of ammonia-fueled ships. The revision of IACS Unified Requirement M77, which now permits the use of aqueous ammonia as a reductant, will play a key role in shaping international safety standards. The maritime industry may witness increased investment in ammonia-based technologies, with stakeholders working to enhance their viability and market readiness.
Beyond the Headlines
The development of Hi-CLEARS highlights the importance of regulatory innovation in advancing eco-friendly maritime solutions. It underscores the need for industry-wide collaboration to overcome technical and safety challenges associated with new fuel types. The successful implementation of ammonia-fueled vessels could influence broader environmental policies and encourage other sectors to explore alternative energy sources.
