DOE has selected seven projects as part of its Critical Components for Coal FIRST Power Plants of the Future. Reaction Engineering International is part of a team led by Washington University (St. Louis, MO) that plans to develop two critical components that are not commercially available for a modular staged, pressurized oxy-combustion (SPOC) plant. The modular SPOC power plant has the potential to deliver near-zero-carbon power to the grid reliably and with high efficiency, low cost, and excellent flexibility.
