Hydrogen and Carbon Black Production from Methane Pyrolysis
Hydrogen has become an important option for the decarbonization of power plants and industrial facilities because the combustion of hydrogen does not produce CO2 emissions. But traditional hydrogen production methods can be two to five times more costly than natural gas. Government incentives mitigate some of the higher costs, but continued innovation is needed to make replacing fossil fuels with hydrogen a viable decarbonization strategy.
To that end, the U.S. Department of Energy (DOE) sought out Lummus Consultants to evaluate a novel hydrogen production technology. Monolith Inc. developed the first commercial-scale technology to employ methane pyrolysis, converting natural gas to produce cleaner carbon black and hydrogen using electric plasma torches powered by renewable energy. The proposed DOE loan guarantee would support Monolith’s facility expansion in Olive Creek, Nebraska, including the installation of 12 pyrolysis reactors, a hydrogen cleanup system, and an ammonia unit.
Monolith’s technology has broad commercial appeal. Carbon black is used for improved strength and abrasion in tire and rubber products, among other applications. Hydrogen is used in many petrochemical applications but chiefly in ammonia and fertilizers, and as a potential alternative fuel to decarbonization power plants and industrial facilities.
As part of our technical review, Lummus Consultants evaluated the technology, execution and operational risks of the expansion project. For example, a key mitigant for technology risk is a demonstration that the existing reactor can produce carbon black within the tire manufacturer’s specification and can operate at levels consistent with the technical assumptions in the financial model. Furthermore, given the project’s size, execution risk was also a concern. The involvement of an experienced EPC contractor and clear definition of responsibilities helped mitigate execution risks.
As Monolith achieves new milestones in the expansion, Lummus Consultants will support the due diligence efforts through financial close, after which we will shift to construction monitoring.
