Get a Custom Ammonia Fuel System Quote in 24 HoursMaritime transport emits ~3% of global greenhouse gases (ICCT, 2024), and the IMO's 2030 (40% reduction) and 2050 (net-zero) targets are looming. Traditional marine fuels—HFO, MGO, and even LNG—can't meet these goals without carbon capture, which adds complexity and cost.
Ammonia isn't just an alternative—it's the only scalable, zero-carbon fuel ready for immediate deployment in 2026.
With 50+ years in high-pressure gas equipment and 20+ years in international marine applications, we offer end-to-end ammonia fuel solutions:
Capacity: 10 m³ to 500 m³
Pressure Rating: 25-40 bar (adjustable for engine requirements)
Materials: 316L stainless steel (corrosion-resistant) or carbon manganese steel with anti-corrosion coating
Temperature Range: -40°C to +50°C (suitable for Arctic and tropical routes)
Safety Features: Double-wall construction, vacuum insulation, leak detection systems, and emergency shutdown valves
Our modular fuel supply skids include:

Our ammonia marine fuel systems meet the highest international standards:
Key Standards: IMO IGF Code (ammonia as fuel), EN 17118 (ammonia purity), ISO 21417 (storage tanks), and SOLAS (safety).
A: Ammonia has a lower energy density by volume (18.6 MJ/kg vs. 42.7 MJ/kg for diesel) but higher by mass. In practice, ammonia-powered engines achieve 85-90% of diesel's efficiency when optimized. (Source: MDPI Hydrogen Production Review)
A: We use 316L stainless steel (with 2-3% molybdenum) or carbon steel with epoxy-phenolic coating. For anhydrous ammonia, water content is kept below 0.2% to eliminate corrosion risks. All tanks undergo pressure and leak testing per ASME Section VIII.

"Shijiazhuang Enric’s ammonia tanks exceeded our expectations. After 6 months of operation on our feeder vessel, we’ve seen zero ammonia leaks and 90% CO₂ reduction. The team’s technical support was responsive and professional—they resolved a minor pressure issue within 12 hours via remote guidance."
"Retrofitting our bulk carriers with Enric’s ammonia systems was 30% cheaper than expected. The modular design allowed us to minimize downtime—our first vessel was back in service in just 2 weeks. Fuel savings have already covered 40% of the retrofit cost in the first year."
"We’ve tested Enric’s ammonia injection systems on our W31 engines, and the results are impressive: 95% combustion efficiency with no ammonia slip. Their PLC control panels integrated seamlessly with our engine management systems. A reliable partner for the ammonia transition."
"As a fuel supplier, we need equipment that meets stringent safety and performance standards. Enric’s ammonia storage tanks passed all our third-party audits (DNV, ABS, LR). Their corrosion-resistant coatings and leak detection systems give us confidence in long-term reliability."
"Switching to ammonia fuel was a strategic move for our sustainability goals. Enric’s turnkey solution—from tanks to engine integration—simplified the process. Their training program ensured our crew was fully prepared, and the 24/7 support has been invaluable."
