Cummins Inc. and Liberty Energy Inc. announced that the industry’s first natural gas variable-speed, large displacement engine will be deployed in the first half of 2025 to power Liberty’s digiPrime hydraulic fracturing platform.
The companies entered into a strategic partnership in June 2024 to jointly develop the revolutionary technology for the completions services market.
The new development for Liberty’s digiPrime platform leverages the existing HSK78G platform. It improves the 78-liter natural gas spark-ignited engine’s response time and load acceptance during operation.
The digiPrime pump, anchored by a 3,000 hp Cummins natural gas variable-speed engine, is a direct drive solution that helps reduce fuel costs. The companies said the new engine is easier to maintain and operate than a standard diesel engine.
“The successful development of the variable-speed digiPrime pump reflects our continued commitment to innovation in pump technology that advances efficiency goals while reducing emissions,” said Ron Gusek, president and named successor to the CEO of Liberty.
