Cooper Expands Use of Hydrogen Fuel in an Integral Engine, Topping 30% by Volume

In March 2022, Cooper Machinery Services (Cooper) successfully tested a slow-speed integral engine running on a hydrogen (H2)- fuel blend (95% natural gas and 5% hydrogen by volume). This month, they greatly exceeded industry expectations by successfully testing the same engine with a fuel blend of 30% H2 by volume, achieving significant reductions in CO, CO2, THC, and methane emissions.
