U.S. petroleum coke, commonly known as petcoke, has maintained consistent production levels over the past decade.
From 2014 to 2023, annual production averaged 46 million tons, with approximately 90% of this being exported.
In 2023 alone, exports reached 41 million tons, exceeding the 10-year average of 40 million tons, according to the EIA of the US Government.
What is petcoke?
Petcoke is a carbon-rich byproduct created during the refining of heavy crude oil.
It serves as a versatile fuel and industrial feedstock.
Depending on its grade, petcoke can either be used as a thermal input for power generation and industrial processes or further processed into high-grade anode petcoke, valued for its electrical conductivity in aluminum and steel smelting.
The refining process and petcoke yield
The production of petcoke is not demand-driven but closely tied to refinery operations.
Refineries equipped with coking units extract petcoke as part of their process to maximize the production of valuable fuels like gasoline and diesel.
Heavier crude oil yields more petcoke, making its production dependent on the type of crude being refined.
Geographical concentration and export importance
Most U.S. petcoke is produced in Gulf Coast and Midwest refineries, which have convenient access to export routes via the Gulf of Mexico and Great Lakes.
This logistical advantage supports steady overseas sales, with Asia and Europe being primary markets. India is a significant destination, using U.S. petcoke as fuel for cement kilns and other industrial processes.
Economic and environmental considerations
Petcoke’s low production cost and high energy content make it a cost-effective fuel. However, its high
Despite these challenges, petcoke’s affordability—typically priced 15% to 20% lower than coal—makes it an attractive energy source for industries equipped to handle its impurities.
Decline in domestic use
While U.S. power generators consumed over 4.4 million tons of petcoke in 2014, this demand fell to 1.8 million tons by 2023.
The decline mirrors coal’s reduced use, as natural gas and renewable energy sources became more competitive.
Even facilities equipped to manage carbon emissions shifted away from petcoke due to these alternative options.
Fuel-grade petcoke: a steady export product
Fuel-grade petcoke, making up 90% of total U.S. petcoke exports, is a critical energy input for cement plants and power plants worldwide.
Its steady annual export volume of 37 million tons reflects strong global demand, particularly from industrialized nations seeking affordable thermal energy solutions.
