QUBLOCK Technology Delivers Critical Valve Solutions for Japan's First Hydrogen-Powered Passenger Ship HANARIA with Zero-Emission

Japanese Engineering Excellence Supports Maritime Decarbonization Milestone

Japan's First Hydrogen-Powered Passenger Ship HANARIA with Zero-Emission

TOKYO, JAPAN – QUBLOCK Technology Co., Ltd., a global leader in advanced industrial valve solutions, has successfully completed the supply of specialized ball valves for the HANARIA, Japan's first hydrogen and biodiesel hybrid passenger ship. This achievement represents a significant milestone in QUBLOCK's commitment to providing reliable valve solutions for emerging green energy applications and demonstrates the company's technical capabilities in hydrogen service.

QUBLOCK's Technical Contribution for hydrogen valve solutions

QUBLOCK supplied 300LB-1B Ball Valves specifically engineered for the hydrogen gas decompression unit operating at 5MPa. These valves were integrated into the hydrogen pressure reducing system for which Fujikin Corporation was responsible as the primary equipment manufacturer.

Technical Specifications: 300LB-1B Ball Valve

The 300LB-1B Ball Valve is engineered for medium-pressure hydrogen applications, providing reliable isolation performance in systems operating up to 5 MPa (approximately 725 psi).

Design Features:

Pressure Rating: ANSI 300LB class, suitable for 5MPa hydrogen service

Body Construction: Single-body design (1B series) offering enhanced structural integrity and reduced leak paths compared to multi-piece constructions

Stem Design: Anti-blowout stem configuration prevents stem ejection under pressure, ensuring operator safety and system integrity

Safety Systems:

• Double Gland Packing – Dual sealing arrangement provides redundant leak protection, critical for preventing hydrogen escape

• Anti-Static Device – Integrated grounding path eliminates static electricity build-up that could create ignition sources in hydrogen environments

• Oil & Water Free Treatment – Complete contamination-free preparation ensures hydrogen purity and prevents seal degradation

• Material Compatibility: Hydrogen-compatible sealing materials resistant to hydrogen embrittlement and permeation

Application Suitability:Designed for use in decompression units where hydrogen is regulated from high storage pressure to controlled downstream levels. The valve ensures secure shutoff during pressure reduction processes, making it ideal for:

• Pressure control skids

• Fuel system modules

• Industrial gas distribution platforms

• Hydrogen re-fueling systems

Performance Validation

Throughout HANARIA's operational testing and zero-emission certification voyage, QUBLOCK's ball valves performed flawlessly. Operators reported "a very quiet and smooth voyage," validating the reliable performance of all critical components, including the hydrogen pressure reduction system.

The vessel's ability to complete the demanding certification voyage without any system failures demonstrates the robust design and quality of QUBLOCK's hydrogen-compatible valve solutions.

QUBLOCK's Expertise in Critical Applications

QUBLOCK's successful contribution to the HANARIA project builds on the company's proven expertise in severe applications requiring solutions for:

• High-pressure environments – Valves rated up to 2500LB class

• Hydrogen service compatibility – Anti-embrittlement materials and zero-leak designs

• Safety-critical systems – Redundant sealing, fail-safe features, and compliance with international standards

• Corrosive and erosive conditions – Specialized materials and coatings

• Extreme temperatures – Cryogenic LNG to superheated steam applications

Based on strict Japanese technology and engineering know-how gained through years of experience, QUBLOCK focuses on challenging applications where tight shutoff and low emissions are essential.

Zero-Leak Valve Technology

QUBLOCK's commitment to zero-leak performance is particularly critical in hydrogen applications. Hydrogen's small molecular size makes it prone to leakage through conventional sealing systems. The 300LB-1B Ball Valve's design addresses this challenge through:

1. Precision-engineered sealing surfaces minimizing leak paths

2. Double gland packing systems providing redundant protection

3. Hydrogen-resistant seal materials preventing degradation over time

4. Single-body construction eliminating body joint leak points
