NEW HYDROGEN TEST ALERT

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, Cooper 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.
