Apparatus and methods for augmenting the Mark 13a process of Van Zelzen et al., by providing for the addition of dispatchable energy storage and / or additional waste stream treatments. Sulfur-containing stack gas emissions from the burning of fossil fuels for electricity production are cleaned, removing the sulfur by use of the Bunsen reaction. The process produces hydrogen and sulfuric acid as byproducts. The hydrogen output of the process can be used to co-produce electricity in a reversible fuel cell, and optionally can be stored so that electricity can be produced during periods of high demand. Optionally the hydrogen can be reacted with air-nitrogen or nitrogen from the combustion gasses to produce ammonia. The sulfuric acid can optionally be reacted with iron or aluminum to produce iron or aluminum sulphates and additional electricity. In addition, mercury removal from the gas emissions from burning fossil fuels (primarily coal) can be performed.

The invention relates to a CO2 emission reduction technology and aims at providing a method and device for preparing CO and H2 by thermochemical cycle decomposition of CO2 and H2O.
