Co-production of hydrogen, electricity and CO from coal with commercially ready technology. Part A: Performance and emissions

Nanoporous Gold Surface: An Efficient Platform for Hydrogen Evolution Reaction at Very Low Overpotential

“…Most electricity generation methods produce CO 2 and such environmental impact can be minimized by using renewable processes. 1,2 In this context, hydrogen is considered to be one of the most important fuels for future energy applications due to its high energy density and the demand for clean and renewable energy sources.…”

“…1,2 In this context, hydrogen is considered to be one of the most important fuels for future energy applications due to its high energy density and the demand for clean and renewable energy sources. 3,4 The main existing process for hydrogen production is based on steam reforming of methane, but such reaction requires catalysts and high energy as input, and CO 2 is as a by-product.…”

Energy, Environmental, and Economic Analyses of Design Concepts for the Co-Production of Fuels and Chemicals with Electricity via Co-Gasification of Coal and Biomass

“…Our simulation of the slurry-feed gasifiers follows closely simulations of this technology reported by Liu, et al (2011). Our simulation of the dry-feed technology is based largely on prior work by Chiesa et al (2005) and Kreutz et al (2005). Literature data for co-gasification of coal and biomass are essentially non-existent, so we have extrapolated from our coal-only simulations.…”

Simulation for Integrated Systems of Typical Coal-to-liquids Processes and Waste Energy Exploitation Based on Different Gasification Processes

“…The result has been obtained that a loss of 6%-8% points of electricity conversion is entailed when capturing CO2 as an alternative to venting it. And CO2 capture for H2 production causes an energy loss about 2% points of export electricity [7]. Recently, many researchers pay their close attention to the polygenerations feeding biomass.…”
