Growing Global Commitment to Biogas and Biomethane Development
As nations accelerate the transition toward renewable energy, biogas and biomethane have become strategic components in achieving carbon neutrality and circular economy goals. The European Union’s REPowerEU Plan targets 35 billion m³ of annual biomethane production by 2030, while similar initiatives in North America and Asia are stimulating new investments in anaerobic digestion and waste-to-energy facilities.
However, expanding biogas production from pilot projects to large-scale commercial plants brings new technical demands. To ensure both process stability and high-quality biogas/biomethane, operators must maintain tight control over gas composition: particularly methane (CH4), carbon dioxide (CO2), oxygen (O2), and hydrogen sulfide (H2S). Accurate, continuous monitoring across production, upgrading, and desulfurization stages has therefore become a key enabler of safe, efficient, and economically viable renewable gas operations.
Operational Complexity Driving Demand for Real-Time and Accurate Biogas Analysis
Unlike conventional industrial gases, biogas is produced under variable biological and environmental conditions. Fluctuations in feedstock composition, digestion temperature, and microbial activity can lead to sudden changes in CH4 and CO2 concentration, while H2S levels may rise sharply when desulfurization systems fail or reach saturation.
High humidity, dust, and corrosive gas components further complicate monitoring. Sensors may experience drift, shortened lifespan, or signal instability, particularly when exposed to condensation or high-H₂S environments. In addition, operators managing decentralized sites such as livestock farms or landfill facilities often require portable tools for routine field verification, maintenance inspection, and research sampling.
Meeting these operational and regulatory challenges demands gas analyzers that are not only precise and robust, but also adaptable to both continuous process control and on-site inspection in harsh field environments.
Comprehensive Monitoring Solutions from Process Control to Field Inspection
Cubic Instruments, a leading manufacturer of gas sensors and gas analyzers, builds upon decades of expertise in precision gas measurement to support the global shift toward renewable energy.
By extending its established measurement capabilities into the biogas and biomethane sectors, Cubic provides comprehensive monitoring solutions that enhance process efficiency, ensure gas quality, and enable safe, sustainable operation of modern biogas facilities.
• Gasboard-3500UV Online Biogas Monitoring System: Continuous Multi-Gas Analysis for Process Control and Gas Quality Assurance
Gasboard-3500UV, developed for continuous biogas process and desulfurization monitoring, utilizes UV-DOAS, NDIR, and electrochemical (ECD) gas sensing technology platforms to simultaneously measure CH4, CO2, O2, and H2S, providing complete visibility across both production and upgrading stages.
During anaerobic digestion, the balance between CH4 and CO2 directly reflects fermentation efficiency and feedstock performance. High-precision NDIR sensor continuously tracks these key components, allowing operators to optimize substrate ratios, maintain ideal process conditions, and maximize methane yield. The electrochemical O2 sensor serves as a safety safeguard that ensures strict anaerobic conditions and prevents oxygen intrusion capable of destabilizing the process.
The modular sensor architecture simplifies service and calibration, and the optional data-logging software supports continuous recording to external PCs for research or regulatory documentation.
To withstand the demanding conditions of biogas environments, Gasboard-3500UV adopts a stainless-steel protective integration cabinet that provides strong corrosion resistance and long-term durability. In addition, the explosion-proof structure further enhances operational safety, enabling reliable installation in outdoor and hazardous areas.
By integrating three core measurement technologies in one platform, Gasboard-3500UV enables operators to optimize production efficiency, protect downstream assets, and maintain consistent gas quality throughout the biogas process chain.
• Gasboard-3200PLUS Handheld Biogas Analyzer: Portable Precision for Flexible On-Site Verification
While stationary system Gasboard-3200UV provides real-time process supervision, operators also need flexible equipment for routine field inspection, maintenance verification, and research sampling.
Cubic Instruments' Gasboard-3200PLUS Handheld Biogas Analyzer provides on-site analysis of CH4, CO2, O2, and H2S based on NDIR and electrochemical (ECD) sensing technologies. It offers high accuracy and rapid response while maintaining stable performance in diverse field conditions. Optional H2 and CO modules further extend its analytical range to address different biogas compositions, while a modular sensor design simplifies maintenance and enhances operational flexibility in multi-site applications.
Designed to maintain precision under fluctuating temperature and humidity, Gasboard-3200PLUS features automatic temperature compensation and precision filters that effectively remove moisture and dust from sample gas to protect internal components and extend sensor lifetime.
Its rechargeable lithium battery provides up to eight hours of continuous operation, ensuring full-day autonomy for field working across dispersed facilities. The lightweight design enables easy transport between inspection points, and the built-in memory can store up to 2,560 data records, which are easily downloaded to a PC for traceability, reporting, or further analysis.
By combining portability, durability, and analytical precision, Gasboard-3200PLUS delivers accurate and reliable performance for critical biogas operations. Operators can evaluate fermentation efficiency, verify scrubber performance, and identify process abnormalities immediately, which helps prevent costly downtime and improve biogas and biomethane yield.
Together, Gasboard-3200UV and Gasboard-3200PLUS form a complementary solution that provides continuous data for process control and flexible verification capabilities for field operation, ensuring full visibility from digester to upgrading stage.
