Expanding methane mitigation with remote power generation for offshore energy production
By Ory Zik, Qnergy
Advancements in remote power generation are reshaping methane mitigation strategies across industries, particularly within offshore natural gas production. Innovative technologies now enable more effective emission reductions, even in remote and challenging environments.
Methane emissions have become a focal point for both regulators and operators, driving efforts to reduce emissions from natural gas production facilities. However, the challenge lies in achieving these reductions while maintaining operational efficiency and managing costs. For offshore production sites, where access and maintenance are expensive, it is critical to deploy highly reliable, low-maintenance technologies that provide consistent performance.
Addressing methane emissions in offshore production
The Free Piston Stirling Engine was designed to deliver efficient methane destruction and adaptable power output for unmanned offshore platforms and multi-well installations.
The Stirling Engine, a technology first conceived more than 200 years ago, is still proving its relevance in contemporary methane mitigation efforts. This engine operates using heat generated through external combustion and requires minimal maintenance.
Key features include no rotating parts or friction; no need for lubricants or oil changes; consistent, grid-quality power output; and 100% methane destruction with zero methane slip and negligible emissions of other gases.
Integration into offshore operations
Integrating Free Piston Stirling Engine generators into offshore natural gas operations can enable operators to meet onshore demand while addressing methane emissions.
Eliminating the maintenance burdens and safety risks associated with conventional power sources, this technology was also designed to enhance environmental compliance and sustainability. It also supports operators in achieving their environmental, social and governance (ESG) objectives.
Gulf of Mexico case study
An operator in the Gulf of Mexico employs Free Piston Stirling Engine generators for remote power. This operator installed PowerGen systems to power battery charging systems across several unmanned platforms. By daisy-chaining the units, the operator ensures uninterrupted, grid-quality energy to support large-scale operations.
To date, the systems have delivered about 80 MWh across 60,000 hours of cumulative run time. This configuration optimizes power reliability and demonstrates the scalability and adaptability of the Stirling Engine in offshore environments.
Broader applications and benefits
Beyond offshore platforms, Stirling Engine-based generators, combined with technologies like compressed air pneumatics, address methane mitigation challenges across diverse settings. These tools emphasize the critical role of advanced technology in fostering cleaner and more sustainable energy production. As the industry continues to prioritize methane reduction, such technologies offer practical pathways for operators to enhance efficiency, ensure compliance and achieve sustainability goals.
