CME 542 EXAM 3 QUESTIONS AND ANSWERS LATEST UPDATE 2023/2024 BEST GRADED A+,EXCELLENT PASS fuel cell - CORRECT ANSWERS Device that combines hydrogen, or other fuels, and oxygen and produces electricity in the process. fuel cell by-products - CORRECT ANSWERS water and heat Fuel cell advantages - CORRECT ANSWERS clean, quiet, and efficient Fuel cell disadvantages - CORRECT ANSWERS expensive, durability, reliability, not easy to store, transportation requires new systems and facilities fuel cell uses - CORRECT ANSWERS hospitals, schools, US department of defense, and bloom energy Fuel cell process - CORRECT ANSWERS Hydrogen fuel is fed into the anode of the fuel cell. Oxygen enters the fuel cell through the cathode. Encouraged by a catalyst, the hydrogen atom splits into a proton and an electron, which take different paths to the cathode. The proton passes through the electrolyte. The electrons create a separate current that can be utilized before they return to the cathode, to be reunited with the hydrogen and oxygen in a molecule of water. alkaline fuel cell - CORRECT ANSWERS 70% efficiency. Used for space shuttle orbit Proton Exchange Membrane (PEM) - CORRECT ANSWERS 40-50% efficiency. A solid membrane in the fuel cell that only allows the passage of protons through it. Used for emergency products and automobiles, portable. Molten Carbonate Fuel Cell - CORRECT ANSWERS 60-80%efficiency. Used for heating buildings on the air station Phosporic Acid Fuel Cell - CORRECT ANSWERS 40-80% efficiency, large, not dependent on the sun CME 542 EXAM 3 QUESTIONS AND ANSWERS LATEST UPDATE 2023/2024 BEST GRADED A+,EXCELLENT PASS Solid Oxide Fuel Cell - CORRECT ANSWERS 50-60% efficiency, most popular, commercial heat. fuel cell applications - CORRECT ANSWERS transportation, stationary power, portable power Stationary Power - CORRECT ANSWERS Back-up power, Stand-alone power, Power for remote locations, Distributed generation for buildings, Co-generation. Portable Power - CORRECT ANSWERS polymer electrolyte membrane (PEM) and direct methanol fuel cell (DMFC) designs. transportation - CORRECT ANSWERS propulsion or auxiliary power Fuel Cell Stack - CORRECT ANSWERS Individual fuel cells that are combined in series. Steam Reforming - CORRECT ANSWERS Process in which steam is used to separate molecules of methane into their component carbon and hydrogen atoms. Separates hydrogen from carbon in methane. Norway - CORRECT ANSWERS first wind to hydrogen system black body radiation of earth should be - CORRECT ANSWERS 252 K, -21 C black body radiation of earth is - CORRECT ANSWERS 288 K, 15 C greenhouse gases - CORRECT ANSWERS carbon dioxide, methane, nitrous oxide, water vapor, and ozone CME 542 EXAM 3 QUESTIONS AND ANSWERS LATEST UPDATE 2023/2024 BEST GRADED A+,EXCELLENT PASS membrane capture disadvantages - CORRECT ANSWERS energy to drive diffusion, materials, humidity of steam Carbon storage options - CORRECT ANSWERS saline aquifers, deep ocean, porous, abandoned oil and gas wells, mineralization carbon transportation options - CORRECT ANSWERS trucks, barge/ship, pipeline CO2 sequestration - CORRECT ANSWERS The process of removing carbon dioxide from the atmosphere and making it unavailable for release back to the air. CO2 sequestration stages - CORRECT ANSWERS capture, dehydration, compression, transport, storage, use. nonpoint source capture - CORRECT ANSWERS sodium hydroxide used to trap CO2, paired with windmill to generate power geo-engineering - CORRECT ANSWERS the deliberate large-scale intervention in the Earth's climate system, in order to moderate global warming passive algae - CORRECT ANSWERS add nutrients to ocean to stimulate growth, agitate ocean to get access to sunlight carbon allowance - CORRECT ANSWERS the amount of CO2 you are allowed to emit carbon credit - CORRECT ANSWERS tradable certificate allowing the right to emit 1 metric tonne of CO2 CME 542 EXAM 3 QUESTIONS AND ANSWERS LATEST UPDATE 2023/2024 BEST GRADED A+,EXCELLENT PASS carbon offset - CORRECT ANSWERS tradable certificate for activity done elsewhere to offset your CO2 emissions Carbon offset vintage - CORRECT ANSWERS the year in which the carbon reduction occurs carbon offset source - CORRECT ANSWERS the project or technology used in offsetting the carbon emissions carbon offset certification - CORRECT ANSWERS the systems and procedures that are used to certify and register carbon offsets California - CORRECT ANSWERS Only US state with a CO2 credit market Offset project types - CORRECT ANSWERS renewables, forestry and land use, methane, efficiency and fuel switching, household device, transportation street enterprise - CORRECT ANSWERS allows government to intervene on emission amounts Carbon compliance market - CORRECT ANSWERS credits are purchased by companies to comply with emission caps Voluntary Market - CORRECT ANSWERS credits purchased by individuals or companies to offset their own emissions Kyoto Protocol - CORRECT ANSWERS controlling global warming by setting greenhouse gas emissions targets for developed countries CME 542 EXAM 3 QUESTIONS AND ANSWERS LATEST UPDATE 2023/2024 BEST GRADED A+,EXCELLENT PASS Paris Climate Agreement - CORRECT ANSWERS An agreement within the United Nations Framework Convention on Climate Change dealing with greenhouse gas emissions mitigation, adaptation and finance starting in the year 2020. US CO2 emissions - CORRECT ANSWERS declined because of fracking EU emissions trading scheme - CORRECT ANSWERS internal market enabling companies to trade carbon dioxide emission permits European Union Emissions Trading Scheme - CORRECT ANSWERS internal market enabling companies to trade carbon dioxide emission permits North American Electric Reliability Council - CORRECT ANSWERS a voluntary organization that was formed as a response to the Great Blackout of 1965 global warming potential - CORRECT ANSWERS a way to normalize all greenhouse gases in order to compare them to carbon dioxide Nitrous Oxide - CORRECT ANSWERS 300 times the global warming potential of CO2 and can be released from agricultural sources, such as nitrogen rich chemical fertilizers concentrations of CO2 in the atmosphere - CORRECT ANSWERS higher than ever recorded natural sources of carbon balance - CORRECT ANSWERS forest, volcanoes natural sinks of carbon balance - CORRECT ANSWERS ocean, plants man-made sources of carbon balance - CORRECT ANSWERS combustion of coal, oil, and natural gas
