clean hydrogen energy and electric power production with co2 capturing by using coal gasification

Clean Hydrogen Energy and Electric Power Production with CO2 Capturing by Using Coal Gasification

Clean hydrogen is the major energy carrier for power production. The conversion of CO to CO2 and zero emission during hydrogen energy production causes high capital cost. It is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. In this era, coal gasification is th...

Sustainable Clean Coal Technology with Power and Methanol Production

Comparative Assessment of Gasification Based Coal Power Plants with Various CO2 Capture Technologies Producing Electricity and Hydrogen

Seven different types of gasification-based coal conversion processes for producing mainly electricity and in some cases hydrogen (H2), with and without carbon dioxide (CO2) capture, were compared on a consistent basis through simulation studies. The flowsheet for each process was developed in a chemical process simulation tool "Aspen Plus". The pressure swing adsorption (PSA), physical absorpt...

Capturing and Sequestering CO2 from a Coal-fired Power Plant - Assessing the Net Energy and Greenhouse Gas Emissions

It is technically feasible to capture CO2 from the flue gas of a coal-fired power plant and various researchers are working to understand the fate of sequestered CO2 and its long term environmental effects. Sequestering CO2 significantly reduces the CO2 emissions from the power plant itself, but this is not the total picture. CO2 capture and sequestration consumes additional energy, thus loweri...

Techno-economic Analysis of Integrated Gasification Fuel Cell Power Plants Capturing Co2

This work analyzes the efficiency and economic performance of different configurations of a coal-fed Integrated Gasification Fuel Cell (IGFC) plant with CO2 capture. Our analysis evaluates novel configurations, providing a detailed economic assessment for each case. The plants studied here are based on a pressurized Solid Oxide Fuel Cell (SOFC) based power cycle integrated with a Shell coal gas...

Studies on Co2 Gasification Reactivity of High Ash Indian Coal

Coal is a prime energy source in India and will continue to play its role for coming several decades. However, our indigenous coal suffers from high ash content and present coal based conventional power generation technologies have several drawbacks such as, lower efficiency, environmental loading and damages thereof. Herein the importance of gasification lies because coal gasification is a mea...
