Zero emission technologies for pneumatic controllers in the USA

The report evaluates zero-emission alternatives to natural gas-driven pneumatic controllers, which are known to release methane. It focuses on electric controllers and solar-powered instrument air systems, finding that both are cost-effective compared to the social cost of methane. The analysis highlights that electric controllers generally offer the lowest abatement costs and that recent technological advancements, such as vertical solar panel stacking and new failsafe systems for Emergency Shut Down (ESD), have expanded the viability of these technologies.

• Recent field measurements indicate that natural gas-driven pneumatic controllers frequently emit methane at rates significantly higher than manufacturer specifications. A 2019 study found abnormal emissions behavior in over 60% of 40 intermittent pneumatic devices and over 20% of 24 low-bleed devices.
• Electric controllers are identified as having the lowest incremental capital expenditure (CAPEX) and methane abatement costs across all assessed site configurations.
• The abatement costs for all assessed zero-emission mitigation options are well below the social cost of methane, which the report benchmarks at $1,500 per metric ton in 2020 USD.
• Technological advancements have reduced barriers to solar power deployment at well sites, including the use of vertical stacking of solar panels to increase capacity within smaller areas and falling prices for PV panels and battery systems.
• New zero-emission Emergency Shut Down (ESD) systems are now available, including a combination of an uninterruptible power supply (UPS) and a failsafe controller (FSC), as well as electric actuators with mechanical fail-safes (e.g., springs).
• The Aurora Eco-System is a new technology providing instrument air powered by solar PV or wind, designed for off-grid locations. It uses a non-continuous rotary compressor that can reduce power requirements by over 50% compared to continuously operating compressors.
• Battery capacity requirements for electric controllers are temperature-dependent; placing batteries in a room at 70 F can reduce required capacity by almost 14% compared to 32 F, while requirements at -4 F are almost 35% higher than at 32 F.
