Cooper and Southern Star Central Gas Pipeline, Inc. have successfully field tested a large bore, slow-speed integral engine running on a 30% hydrogen (H2) fuel blend. The two companies modified a large bore Cooper-Bessemer GMVH-12 at Southern Star’s Hugoton, Kansas compressor station to run on a blend of hydrogen and natural gas. The engine was equipped with Cooper’s HyperBalance IV™ system to monitor pressures, collect data, and ensure equipment safety during the test.

The reduction of greenhouse gases is a key element of Cooper’s emissions reduction technology offering. To improve the environmental impact of engine-compressors operating within our industry, Cooper introduces CleanBurn Plus™, an emissions reduction solution tailored to reduce not only current regulated emissions constituents such as NOx, CO, and VOC, but also methane in the form of unburned hydrocarbons.

As The global leader for engine and compressor support and supply, Cooper stands ready.
