In 2016 natural gas was used to provide 35% of all energy in Canada, double the amount supplied by electricity. [18] Electricity generated by natural gas was 8.5% of the nation's total. Natural gas is used to supply 50% of space heating, and 65% of water heating in homes, similarly 80% of businesses use natural gas for space and water heating. [19]
The Wobbe index is expressed in MJ/Nm³ (where 'Nm³' indicates'm³ in Normal conditions), or sometimes in BTU/scf.In the case of natural gas (molar mass 17 g/mol), the typical heating value is around 39 MJ/Nm³ (1,050 BTU/scf) and the specific gravity is approximately 0.59, giving a typical Wobbe index of 51 MJ/Nm³ (1,367 BTU/scf).
In all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, respectively, and for natural gas about 11%.
The average home using heating oil is projected to pay $1,851 to keep warm, compared to $601 for an average home using natural gas or $1,063 for electricity, the EIA said.
The price of natural gas varies greatly depending on location and type of consumer. The typical caloric value of natural gas is roughly 1,000 BTU per cubic foot, depending on gas composition. Natural gas in the United States is traded as a futures contract on the New York Mercantile Exchange. Each contract is for 10,000 million BTU or 10 ...
Natural gas prices are down 13% year to date, largely because of milder winters and a supply glut. But industry watchers are betting on increasing gas exports and greater power demand from the on ...
The quality of the gas is measured and adjusted for in each billing cycle. This is known by several names as the calorific value, heating value, or therm value. The calorific value of natural gas can be obtained using a process gas chromatograph, which measures the amount of each constituent of the gas, namely: methane; ethane; hydrogen; carbon ...
Natural gas production companies can't seem to catch a break. Despite more successful drilling and production numbers in 2012, lack of demand sank spot prices to 12-year lows. Now, just as these ...
