TADI: A Testing Center for Methane Emission Detection and Quantification Technologies; Improving Accuracy and Reliability of GHG Measurement Technologies on Sites

Abstract Methane emissions face growing regulatory and societal pressure, requiring accurate and transparent detection and quantification technologies. A worldwide energy company created TADI (TotalEnergies Anomaly Detection Initiatives), to address this challenge. Located at the PERL (Platform for Experimental Research in Lacq) site in Lacq, France, TADI has been operated for more than 10 years now and offers controlled and field-realistic conditions to evaluate detection and quantification technologies under operational constraints and real weather conditions. The platform incorporates independent witnessing by Bureau Veritas, rigorous metrological practices, and a standardized international protocol developed in collaboration with METEC (Methane Emissions Technology Evaluation Center at Colorado State University (USA). This ensures scientifically robust and comparable evaluations. Since its inception, TADI has conducted more than 2,600 tests, evaluated over 50 technologies, and selected several technologies for internal use within the company. Since late 2024, TADI has opened its facility to external partners, fostering international collaboration and harmonizing testing standards. By accelerating innovation and supporting regulatory compliance, TADI serves as a catalyst for the future of methane monitoring and industrial technologies deployment.
