The price as at 20 January 2022, on the U.S. Henry Hub index, is US$3.87/ MMBtu ($13.2/ MWh). [4] The highest peak (weekly price) was US$14.49/MMBtu ($49.4/MWh) in January 2005. [5] The 2012 surge in fracking oil and gas in the U.S. resulted in lower gas prices in the U.S. This has led to discussions in Asian oil-linked gas markets to import ...
The system to evaporate the leachate costs $300,000 to $500,000 to put in place with operations and maintenance costs of $70,000 to $95,000 per year. A 30,000 gallons per day evaporator costs $.05 - $.06 per gallon. The cost per gallon increases as the evaporator size decreases. A 10,000 gallons per day evaporator costs $.18 - $.20 per gallon. [9]
This volume of CNG at 2,400 psi has the same energy content as one US gallon of gasoline (based on lower heating values: 148,144 BTU/cu ft (1,533.25 kWh/m 3) of CNG and 114,000 BTU/US gal (8.8 kWh/L) of gasoline. [22] Using Boyle's law, the equivalent GGE at 3,600 psi (25 MPa) is 0.51 cubic feet (14 litres; 3.8 US gallons).
The energy obtainable from burning one US gallon of gasoline is 115,000 BTU, 33.70 kWh, or 121.3 MJ. [8] To convert the mile per gallon rating into other units of distance per unit energy used, the mile per gallon value can be multiplied by one of the following factors to obtain other units: 1 MPGe.
This is about 50 to 54 MJ/kg depending on the density. [164] [165] For comparison, the heat of combustion of pure methane is 37.7 MJ per standard cubic metre, or 55.5 MJ/kg. Except in the European Union, the U.S., and Canada, natural gas is sold in gigajoule retail units.
Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram. [21] 7: N: Nitrogen: 0.0012506: 19 (5.263 × 10 17 kg) 0. ...
In light-water reactors, 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 kg of coal. [16] Comparatively, coal, gas, and petroleum are the current primary energy sources in the U.S. [17] but have a much lower energy ...
sievert (SI unit) Sv. ≡ 1 J/kg [44] = 1 Sv = 1 J/kg = 1 m 2 ⋅s 2. Although the definitions for sievert (Sv) and gray (Gy) would seem to indicate that they measure the same quantities, this is not the case. The effect of receiving a certain dose of radiation (given as Gy) is variable and depends on many factors, thus a new unit was needed to ...
