CCC has developed advanced technology products for modernizing Natural Gas Fuel Systems to meet the latest emissions compliance regulations. Gas engine Complete Emission Reductions Systems, including fuel flow measurement for Natural Gas (and Biogas) to document carbon reduction and help earn carbon credits. CCC's Gas Turbine Smart Fuel Metering controls are manufactured with embedded sensors for the fastest Flow Control in the Industry for managing fuel quality and load changes while maintaining strict emissions compliance. Continental Controls Corporation was originally co-founded in 1968 by Ross Fisher; now retired in Indiana. The company quickly established a prominent place in the gas turbine industry by developing speed and temperature monitors and then fuel control modules used primarily with Solar Turbine engines. These controls became known as Solar "Black Boxes" and are still being manufactured today. In the early 1970s, CCC developed innovative electronic controls for Gas Turbine Compressor applications, a Generator Set Control system (that became known as a KS Gen Set and was in more than 350 locations by telephone companies), and a very early control system for reciprocating engines. Mr. Fisher was responsible for the design and development of all of the CCC products during this time. In 1979 CCC was sold to The Bendix Corporation but continued to operate as Continental Controls / Bendix. In 1989 Mr. Fisher left Bendix and acquired the rights to the Continental Controls name as well as the rights to manufacture the Black Box products that he had developed. CCC now continues to offer the "Black Boxes" both new and refurbished, as well as the latest in turbine control systems and advanced gas and liquid fuel metering valves.

California-based Oberon Fuels is on a global mission to decarbonize transportation by producing a powerful, enabling molecule, dimethyl ether (DME). DME, which can range from being ultra-low carbon to carbon-negative, can significantly reduce the carbon footprint of the transportation sector and beyond 1) as an energy-dense, cost-effective means to move renewable hydrogen, 2) as a blending agent for LPG, and 3) as a diesel replacement. Oberon has challenged the status quo by introducing innovative solutions to the transportation sector to reduce its carbon footprint, vehicle emissions and improve local air quality while creating economic opportunity for the communities where they operate. In 2013, Oberon Fuels’ refinery in Brawley, Calif., produced the first fuel-grade DME in North America, and in 2021 produced the first-ever renewable DME in the US. Oberon’s DME has powered vehicle demonstrations around the world with Volvo Trucks, Mack Trucks, Ford, among others. Founded in 2010, Oberon Fuels is privately held with both private and strategic investors, including Suburban Propane Partners, L.P. (NYSE: SPH).
