Question

An average pulverized-coal power plant has an efficiency of about 33% .Suppose a new ultra- supercritical coal plant increases that to 40% .Assume burning coal emits 85kgCO_(2)/GJ .If CO _(2) emissions are eventually taxed at $40 per metric ton (1metric ton =10^(3)kg ) what would the tax savings be (in $/kWh ) for the supercritical plant?​

Answer 1

Answer:

Overall thermal efficiency for oxygen-blown coal gasification, including carbon dioxide capture and sequestration, is about 73%. Using the hydrogen in a gas turbine for electricity generation is efficient, so the overall system has long-term potential to achieve an efficiency of up to 60%
