A Quick Tour of our work this summer to find and fix the biggest leaks first.

The hunt for Large Volume Leaks (LVL) gas leaks is on.
Just 7% of the leaks are gushing out half the gas. Fixing these leaks is the fastest way to reduce methane emissions coming from our underground pipes. Unfortunately, the utilities didn’t have a proven method ready to identify these largest leaks.

HEET partnered with Columbia Gas, Eversource, and National Grid on a pilot study to find an inexpensive, reliable method of pinpointing the highest volume leaks. They’ve sent us the addresses of leaks they believe are gushers. We studied each leak using multiple different technologies. We determined which leaks are actually the biggest using the Chamber Method, and compared all the other approaches, finding options for the utilities to use to identify, prioritize, and fix all the big leaks.

Together with Millibar, Boston University Professor Nathan Phillips, an MIT Hackathon, Gas Safety Inc., Eversource, and Columbia Gas, we’ve helped invent the FluxBar.  The FluxBar is a tool to measure the flow of gas from a leak. It works quickly and is rugged and easy for the utilities to use.

Our team created the FluxBar by modifying a standard utility tool that vacuums gas out of the earth under the street.  We simply modified the device to decrease and control the speed of the suction, while adding a way to measure the amount of gas being vacuumed.
