Integrated Solutions for the LNG Industry

Supporting the journey to decarbonization

Bridging the gap

The share of renewable energy continues to increase worldwide and now accounts for almost one-third of annual global electricity consumption. However, wind and solar energy are intermittent, and we don’t currently have the means to effectively store surplus electricity from these sources for distribution on overcast and windless days. Additionally, power grids were designed for a steady supply of electricity to avoid power blackouts. This is why natural gas, which burns cleaner than other fossil fuels, is an important part of the solution as a reliable complement to renewable energy.

Electric motor-driven main refrigeration trains continue to emerge as a powerful decarbonization pathway for LNG project stakeholders. However, the development of eLNG facilities often presents unique technical challenges not encountered with traditional gas turbine-driven designs. Ensuring efficiency and reliability of grid-connected eLNG plants is key.

LNG production plant features a first-of-its-kind hybrid drive refrigeration unit for optimized performance, flexibility, and economics – while minimizing environmental impact.

BOG and Auxiliary Compression Trains

Siemens Energy offers solutions for all compression tasks at liquefaction and regasification terminals. We are one of very few companies that can provide fully integrated compression solutions with driver and all auxiliary systems on a base frame for ease of handling and reduced site installation time. The equipment we supply includes compressors for main refrigerant cycles, natural-gas booster compressors, and boil-off and end-flash gas compressors. Depending on plant design, compressors can be driven by an electrical or mechanical drive system.

With over 90% market share in cryogenic BOG compression, we have the experience to handle your most difficult application challenges.

E-houses and Modules

Siemens Energy draws on decades of experience to offer highly reliable plug-and-play modules for power generation (high-, medium-, and low- voltage power distribution) and compression for both offshore and onshore applications.

Modular construction of LNG facilities helps mitigate the risk associated with project cost overruns and schedule delays, which often occur as a result of complications during onsite construction. This has particularly been the case for module development across Asia and plants built in harsh and/or remote operating environments. Siemens Energy has extensive experience leveraging modularization to streamline development of LNG facilities and minimize overall risk to project stakeholders.
