zeroBOG cryogenic applications

Introduction


As the energy landscape evolves, the need for flexible and future-proof cryogenic solutions is greater than ever. While boil-off gas (BOG) management is essential for liquefied natural gas (LNG) shipping and terminals, emerging fuels like Bio-LNG and liquid hydrogen are creating new challenges and opportunities. Sulzer’s zeroBOG™ technology is engineered to meet these demands not just for LNG, but for a wide range of cryogenic applications that are shaping the future of clean energy.


The Expanding Role of Cryogenic Fuels


Bio-LNG and liquid hydrogen are gaining momentum as cleaner alternatives to conventional fossil fuels. Both require storage and transport at extremely low temperatures, leading to the inevitable generation of boil-off gas. Efficient management of this BOG is crucial for:

  • Preserving fuel value and purity

  • Ensuring safe and reliable operations

  • Minimizing emissions and environmental impact


zeroBOG™: Versatile Technology for Tomorrow’s Fuels


zeroBOG™ stands out as a proven, compact, and modular solution for BOG recondensation across multiple cryogenic applications:

  • Bio-LNG: As the market for renewable LNG grows, zeroBOG™ enables operators to manage BOG efficiently, supporting sustainable fuel supply chains and reducing greenhouse gas emissions.

  • Liquid Hydrogen: With its extremely low boiling point and high volatility, hydrogen presents unique challenges. zeroBOG™’s robust design and minimal pressure drop (<0.5 bar) make it ideal for hydrogen storage and transport, including rocket and spaceship fuel systems.

  • Other Cryogenic Systems: zeroBOG™ is also suitable for refueling stations, floating storage and regasification units (FSRU), floating LNG (FLNG), and more.


Key Benefits Across Applications


  • Compact and modular: Up to five times smaller than traditional BOG recondensers, zeroBOG™ fits easily into new and existing infrastructure, whether on land or at sea.

  • Operational stability: Maintains high efficiency even with fluctuating BOG flow rates and challenging offshore or mobile conditions.

  • Ease of use: Self-regulating and simple to operate, zeroBOG™ is adaptable for a range of fuels and operational requirements.


Future-Proofing Cryogenic Infrastructure


By investing in zeroBOG™, operators ensure their facilities are ready for the transition to alternative fuels. Its versatility means that as energy markets shift from LNG to Bio-LNG, hydrogen, or other cryogenic solutions, zeroBOG™ remains a valuable asset delivering reliable BOG management and supporting decarbonization goals.


Conclusion


Sulzer’s zeroBOG™ is more than an LNG solution. Its adaptability, efficiency, and compact design make it the technology of choice for operators looking to embrace the future of cryogenic fuels, from Bio-LNG to hydrogen and beyond.
