Recovery Act: Scale-Up of Hydrogen Transport Membranes for IGCC and FutureGen Plants

Performer: Eltron Research & Development Inc.

Project No: FC26-05NT42469

Project Description

The Eltron Hydrogen Transport Membrane (HTM) technology uses composite metal alloy materials to separate H2 from coal-derived syngas (a mixture of H2, CO, CO2, and steam). Carbon dioxide on the feed side of the membrane remains at high pressure and in a concentrated form suitable for capture and re-use or storage. The Eltron HTM system is an enabling technology for the production of high purity H2 and the capture of CO2 at high pressure that is applicable to future integrated gasification combined cycle (IGCC) and central station H2 production plants. These novel membranes have an operating temperature of 280 to 440 degrees Celsius (°C), which is well-matched with emerging coal gas cleaning technologies and has the potential to significantly improve the overall efficiency and process economics for future gasification-based power, fuels, and chemical production plants. Eltron’s membranes can withstand differential pressures of up to 1,000 pounds per square inch gauge (psig) without structural failure, allowing for successful integration into advanced, high-pressure coal gasification plants.

Eltron is currently executing the project in two distinct parts: Part 1, entitled "Scale-up of Hydrogen Transport Membranes for IGCC and Coal-to-Hydrogen Production Plants," is the base project, and Part 2, entitled "Scale-up of Hydrogen Transport Membranes (HTM)," is the ARRA-funded extension of the project. In Part 1, Eltron has sub-contracted with Eastman Chemical Company to scale-up this technology and conduct testing using coal-derived syngas. Eltron and Eastman will design, construct, and operate a nominally 12-lb./day scaled-up HTM module on coal-derived syngas. In Part 2, Eltron will accelerate the design, construction, and operation of a 250-lb./day module and further scale the technology to a nominal 4 to 10 ton/day hydrogen production module.

The primary goal of this American Recovery and Reinvestment Act of 2009 (ARRA) project is to test for energy efficient industrial carbon capture and storage (ICCS) using Eltron Research Inc.'s HTM system for H2 separation and CO2 capture. This project will accelerate development and scale-up of Eltron's ongoing research and development by accelerating the work and broadening the scope of the existing HTM project. Eltron will update process models and conduct a techno-economic analysis and perform studies on integration of this technology into viable industrial applications, thus providing a carbon capture and storage component. Efforts under this project will significantly accelerate analyses of the design, scale-up, cost, performance, and operating data for future HTM-ICCS integrated clean energy systems.
