The phrase "OPAL oil" does not refer to a traditional petroleum-derived lubricant or crude oil commodity, but rather represents a common naming confusion surrounding OPAL Fuels and its renewable energy operations. The company does not drill for or refine conventional crude oil. Instead, its core business focuses on capturing raw methane gas escaping from organic waste in landfills, purifying it into pipeline-quality renewable natural gas, and supplying it as a clean alternative fuel for heavy-duty commercial transport. Any references to oil in this context typically stem from general comparisons between traditional fossil fuel markets and the low-carbon renewable fuel alternatives developed by the enterprise.
