Gasification Technology Developed for the Production of Renewable Hydrogen


Keywords: , , ,

Hydrogen fuels from renewable sources are considered some of the most promising alternative fuels for reducing oil consumption, greenhouse gas emissions, and air pollution. Sierra Energy’s FastOx technology is a fixed-bed gasification system that breaks down waste at the molecular level by injecting oxygen and steam at highly-concentrated and rapid rates. The main product is a clean and high-quality syngas, which is an intermediate fuel used to produce valuable energy products, such as hydrogen. Using the H2A model and experts from NREL, Sierra Energy calculated that the FastOx gasifier can produce hydrogen at a cost of $1–$5/kg(H2) with systems ranging from 12.5 MTPD to 100 MTPD. For vehicular transportation, a 100 MTPD system can produce hydrogen at an industry-leading $0.43/GGE. Coupled with the benefits of eliminating waste, reducing greenhouse gas emissions, and fueling economic growth, the production of renewable hydrogen with FastOx gasification is a paradigm shift from conventional operations. This presentation will introduce the FastOx gasification process, review the performance of the pilot system in comparison with conventional technologies, examine the process and economics of hydrogen production using FastOx and explain the environmental impact with a developed hydrogen case study using California MSW.
