Company Overview

Prometheus was formed in April of 2010 with the purpose of designing and selling prechamber spark plugs while providing combustion solutions for the stationary, natural gas engine market (Power Generation & Gas Compression). Since then, Prometheus’ reach has extended, through global partnership channels, to Marine Propulsion, Automotive, Racing and UAV engine applications.

Prometheus is located in Fort Collins, Colorado and in Munich, Germany. Its facilities include engineering offices, computer clusters and labs for bench simulations of spark ignition and combustion phenomena in optical chambers. Here, advanced combustion CFD modeling and simulation algorithms are validated and used to develop eco-friendly combustion solutions through the use of carbon-free and carbon-neutral fuels such as hydrogen, ammonia, methanol, biogas, natural gas, etc.

Prometheus’ offerings include hi-tech prechamber products, innovative combustion solutions, engineering consulting and training services and are supported by numerous international patents and technical publications.
