Natural gas consumption

EJ = 0.9488 X 10 Btu. Assumes market incentives of 2 /kWh on fossil fuel-based electricity generation, 2.00/10 Btu on direct coal and petroleum consumption, and 1.00/10 Btu on direct natural gas consumption. 

The gas reservoirs located ia very deep waters, ia coal beds, and ia tight sands are now more accessible. Fifteen percent of the U.S. gas supply ia 1992 was derived from tight sand formations and 1.4 x 10 of coal-bed methane was added to the proven reserves (22). In 1992, U.S. proven reserves were placed at 4.67 x 10 ia the lower 48 states, and it was estimated that the identified gas resource ia the United States and Canada exceeds 3.4 X 10. Based on the 1992 rate of natural gas consumption, the United States has between 8 and 10 years of proven reserves and a domestic... 

This excess hydrogen is normally carried forward to be compressed into the synthesis loop, from which it is ultimately purged as fuel. Addition of by-product CO2 where available may be advantageous in that it serves to adjust the reformed gas to a more stoichiometric composition gas for methanol production, which results in a decrease in natural gas consumption (8). Carbon-rich off-gases from other sources, such as acetylene units, can also be used to provide supplemental synthesis gas. Alternatively, the hydrogen-rich purge gas can be an attractive feedstock for ammonia production (9).

Implementation of the 1998 Kyoto Protocol, which is designed to reduce global carbon emissions, will have dramatic effects on fossil fuel usage worldwide. The Kyoto Protocol mostly affects delivered prices for coal and conversion of plants to natural gas, nuclear and/or renewable resources. However, as pointed out by the International Energy Agency, increased natural gas consumption in the United States may likely have the effect of increased reliance...

Glaeser and Kahn [16] evaluated the emissions released by American households for heating purposes. The two primary heating sources for households are fuel oil and natural gas. On the one hand in the United States, the use of fuel oil is pretty rare, with the exception of the Northeast, and it is used as a source of home heating in few metropolitan areas on the other hand, natural gas is the most common home heating source and in some areas electricity is also used. Natural gas consumption is driven primarily by climate. 

But, natural gas may be the wrong fuel on which to base a hydrogen-based transportation system. A large fraction of new U.S. natural gas consumption will probably need to be supplied from overseas. While these sources are more secure than the sources for oil, replacing one import with another does not move us towards energy independence. 

This means that energy use would have to become twice as efficient. This future vision has natural gas consumption increasing through 2025 and then dropping due to supply problems. 

In analogy to oil, in the following it is analysed how the projected increase in natural gas consumption will affect the time of the mid-depletion point of gas production. The methodological approach is the same as described for oil in Section 3.3.4. The discussion about a possible peaking of gas production is (still) less controversial than for oil. 

The upper limit of energy potentially capable of being produced from a marine or ocean based biomass has not yet been determined, but it is estimated that the potential contribution to the long-term U.S. energy supply could be at least equal to today s natural gas consumption or 20 quads per year. 

According to the vendor, the capital and operating costs associated with a PCC biofiltration system vary depending on site-specific factors. The capital cost of the system is directly related to the size of the reactor. The size of the reactor is dependent on the flow rate, chemical composition, and concentration. The operating costs often include electricity consumption, natural gas consumption, steam, maintenance cost, filter media replacement, water consumption, and media disposal. These operating costs are directly related to the design and size of the biofilter (D213161, pp. 1 2). 

From 1996 to 2000, the natural gas consumption in Italy grew from around 56.2 billion cubic metres to 70.4 billion, a rise that derived primarily from growth in the power generation sector, in which consumption doubled. In the same period, natural gas was the primary energy source that grew most rapidly, increasing at an average annual rate of 5.8%. 

Satisfactory results, as indicated by relatively steady natural gas consumption and slowly increasing vacuum, were recorded until early August 1996, when flows increased and the system vacuum began to drop. A second set of mini-pilot tests was completed on August 24, 1996. The... 

Mixed results, as indicated by the decreasing gasoline-equivalent hydrocarbon burn rate and increasing natural gas consumption, were observed after these adjustments to the system. The gasoline-equivalent hydrocarbon burn rate decreased from between 0.55 and 0.60 gal/hr to between 0.25 and 0.30 gal/hr. However, by the next set of mini-pilot tests, completed on November 19, 1996, the bubblers were successful in removing not only the PSH in these two wells, but also a significant portion of the PSH present in monitor wells in the vicinity.
