MONITOR Field Test Site

Default ARPA-E Project Image

Fort Collins, Colorado
Project Term:
10/01/2016 - 09/30/2019

Technology Description:

The team, led by Colorado State University (CSU), will develop a test site facility near Fort Collins, CO where ARPA-E can evaluate the methane sensing technologies of the MONITOR project teams, as required by the MONITOR FOA. The CSU team will design, construct, and operate a natural gas testing facility that can determine whether MONITOR technologies have met or exceeded the technical performance targets set forth by the MONITOR program. The test facility will be designed to realistically mimic the layout of a broad range of natural gas facilities and equipment. The test facility will include a number of controlled natural gas emission release points that will be realistic in terms of location, magnitude, frequency, duration, and gas composition. The design will also include sub-facilities that can simulate different aspects of the natural gas industry supply chain such as dry gas production, wet gas production, midstream compression, metering and regulating stations, and underground pipeline releases. The test site is located in the Denver-Julesburg basin, but will be sufficiently far enough away from natural gas operations that background levels of methane will be very low. Thus, the site will provide a realistic, but highly controllable environment within which the MONITOR technologies can be accurately tested.

Potential Impact:

If successful, the technologies developed under the MONITOR program would generate highly sensitive methodologies for locating and characterizing methane leaks at natural gas well sites with greater precision at much lower cost.


MONITOR projects aim to improve the safety and efficiency of domestic natural gas production by detecting methane leaks and minimizing lost product.


Enhanced detection capabilities could significantly reduce fugitive methane emissions and lead to an overall reduction in harmful greenhouse gas emissions associated with natural gas development.


MONITOR program innovations aim to give producers the tools to decrease the cost of natural gas leak detection and spur a growing emissions services industry at the nation’s more than 480,000 producing natural gas wells, all while keeping natural gas costs low.
