e.g. A therm weighs 4.25 pounds but at atmospheric pressures a therm of natural gas has a volume of 100 cubic feet (5' by 5' by 4' ). My point is that we don't have to ignore the magnitude of our emissions. What details make Lochinvar an attractive and romantic figure? Reply (14 pounds CO2e for leakage and 11.7 lbs for combustion.). How will understanding of attitudes and predisposition enhance teaching? 3.2 pounds of Carbon (We dyed it yellow) see bottle to the right, 8.5 pounds of O2 (We dyed it blue in 2 two-liter plastic bottles.). All Rights Reserved. How long does it take to cook a 23 pound turkey in an oven? We then hand them the upstream shrinkage of 2 pounds. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so 100 cubic feet = 2.04 kg A therm is enough energy to heat 100,000 lb of water by one degree F. e.g. Did you make this project? My direct household usage is about 190 therms of natural gas per year and shrinking and about 440 gallons of gasoline per year. Fuel is not equal to fuel - at least if we consider carbon dioxide emissions. See clear bottles in the cloth bag. Each 1% amount of leakage with a 100 year Global Warming Potential of 84 times its weight in CO2e amounts to an added 3.5 pounds of CO2e emissions. You can multiply by numbers in my instructables to calculate that part of my carbon footprint. The fugitive emissions of raw methane are called "leakage". So far, so good. The Students really get the weight of the issue. Burning of lignite emits nearly 100 % more carbon dioxide with respect to the energy content than burning of natural gas. CO2 emission factor for Natural gas is: 0.056 kg CO2eq/MJ energy equivalent. The all in weight for a therm with 4% leakage amounted to a very provocative 28 pounds of CO2e. What is the contribution of candido bartolome to gymnastics? While combustion of natural gas does produce carbon dioxide, it produces about 30 percent less than oil and 45 percent less than coal, and natural gas doesn't produce ash particles like coal and oil do, which adds to air pollution. Green house gas emissions data from burning fossil fuels, like natural gas or heating oil is relatively easy to come but can be confusing. Fixed rates in Georgia are less than $0.50 per therm. Natural gas is primarily methane (CH4), which has a higher energy content relative to other fuels, and thus, it has a relatively lower CO2-to-energy content. nice visual representation of issues associated with fuel delivery. Okay, I see this is your second attempt at posting suspect and "iffy" projects about that evil "Man-Made Global Warming". IDK! According to U.S. EPA, Inventory of U.S. Greenhouse Gas The 3.2 lbs of Carbon (C) is oxidized by 8.5 pounds of atmospheric oxygen (O2) to create 11.7 pounds of CO2. The 5% shrinkage (Gas consumption to pressurize the remaining gas Amounts to .6 pounds of CO2 emissions. There are 0.00576 metric tonnes of CO2e per gallon of propane. Methane has an 84 GWP but it has a lower molecular weight of 16 (1 C @12 and 4 H @ 1 =16) compared to CO2's molecular wt of 44 (1 C @ 12 + 2 O @ 16 each). You are correct that I use fossil fuels. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. I still do not see what is "iffy" or "suspect" in my instructable. The little "e" in CO2e means it's an equivalent Global Warming Potential (GWP) weight for a mix of CO2 and some methane. So 11.7 * 1%* 30.5 = 3.57 pounds per therm for each 1% of leakage. 1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. When did organ music become associated with baseball? Design and 3D Print Your Own Phone Case (in Fusion 360). There are 0.00531 metric tonnes of CO2e per 100 cubic feet (CCF) of natural gas. Emissions and Sinks: 1990-2004, I am sure you are using and enjoying the exact same energy sources you seem to be worried and equally complaining about. you can't burn the carbon without using the oxygen and you can't get the methane to your home without incurring the shrinkage and leakage. This way we could discuss leakage reduction and remove one or two bottles at 1% leakage reduction, each. Share it with us! Creates: tonnes of CO2: Volume of CO2: m 3: ft 3: Height in m 3 units Yellow table above displays results. Why don't libraries smell like bookstores? We next ask them to lift higher to lift the bag with 4% leakage (4 times 3.5 pounds of CO2e = 14 pounds from leakage) for a total COe2 weight of 27 pounds CO2e per therm. We have the "student" first lift the 3.2 pounds of carbon, then lift higher to pick up the 8.5 pounds of O2 making 11.7 pounds of tailpipe emissions. What is the conflict of the story of sinigang? Wow, you are paying out the nose for gas in California. It's enough to heat water for 74 minutes of showering with a 2 gallon per minute shower-head. The 3.2 lbs of Carbon (C) is oxidized by 8.5 pounds of atmospheric oxygen (O2) to create 11.7 pounds of CO2. The 5% shrinkage (Gas consumption to pressurize the remaining gas Amounts to .6 pounds of CO2 emissions. Who is the longest reigning WWE Champion of all time? (Source: U.S. Department of Energy) Propane. Every couple hundred miles along the way, some gas is piped out into combustion turbines that burn it and use its mechanical energy to re-compress the rest of the gas in the pipeline to send it further on its way. heat about 12,000 gallons by one degree F or heat 120 gallons by 100 Degrees F. A therm is about what a family of 3 uses in their water heater for 2 or 3 days. Water and various elements, such as sulfur and non-combustible elements in some fuels reduce their heating values and increase their CO2-to-heat contents." A therm has 3.2 pounds of Carbon and 1.06 pounds of Hydrogen. Even natural fuels such as wood or peat have high specific emissions, if they are not used sustainable. I also believe satisfaction can be found in making progress towards solving problems. I lay out information and sources in a clear way so readers can replicate the calculations, and search the sources. The average carbon dioxide coefficient of natural gas is 0.0549 kg CO 2 per cubic foot (EIA 2019c). Inter state form of sales tax income tax? Vehicles. We use weights (bottles filled with specific weights of dyed water to represent one gas therm's actual weight of, carbon in the fuel, oxygen for combustion, CO2 from shrinkage (pipeline consumption) and Equivalent CO2e from leakage of methane. Air Travel. What is plot of the story Sinigang by Marby Villaceran? It shows the calculations that find a Therm of natural gas (Methane or CH4) A therm has 3.2 pounds of Carbon and 1.06 pounds of Hydrogen. The key is to find the heat content of natural gas that your energy provider uses. The fraction oxidized to CO 2 is 100 percent (IPCC 2006). There are lots of ways to reduce our emissions. The really big problem is leakage. How many tons of CO2 emissions per therm of natural gas? I think they will remember this for a long time. With 4 % leakage, most of the equivalent CO2e is coming from leakage not combustion. It shows the calculations that find a Therm of natural gas (Methane or CH4). of carbon dioxide emissions. i think this clearly shows the importance of on site power generation that will reduce "wasted " fuel - that in itself will aid in resizing emissions. I show my methods and assumptions. I have no problem with demonstrating science and educating people about our energy systems. As noted above, that varies, but the national annual average in 2019 was 1,037 Btu per cubic foot, where 1 Ccf equals 1.037 therms. So what IS your point? Since natural gas drilling, compression, storage and distribution systems are now being found to be pretty leaky, (>4% leakage) that amounts to more than half of the total CO2e emissions of a therm. Natural gas emissions are shown as being about 40% below those of coal and 50% below those of coke simply on an energy basis (note that this is a simple combustion calculation and does not reflect factors such as the often found lower efficiency of older coal units in many countries, e.g. Hence, deforestation has a high impact on climate change. Four 3.5 pound bottles with each representing 1 % methane leakage. 1 therm of natural gas burnt produces 11.7 lbs.
