Sentences with phrase «natural gas combustion»

The interest in natural gas combustion as a potential solution to climate change has been gaining because US ghg emissions have fallen somewhat as natural gas from hydraulic fracturing technologies has been rapidly replacing coal in electricity sector generation.

«The [latest models of] natural gas combustion turbines that would be purchased to provide capacity have a levelized cost of energy of $ 0.194 / kWh and run 20 % of the year, according to the 2014 Tucson Electric Power IRP,» Lon Huber, a consultant for the Arizona consumer advocate, told Utility Dive.

For this reason, any reliance on natural gas combustion as a method of reducing CO2 emissions must provide for ramped up commitments to non-fossil fuel sources of energy at levels needed to prevent dangerous climate change.

Even if natural gas combustion creates approaching 50 percent less CO2 equivalent per unit of energy produced, an amount which is well beyond best case on ghg emission reductions, it will not create the much greater emissions reductions necessary in the next 30 years to give any hope of limiting warming from exceeding levels that will cause catastrophic impacts.

«The [latest models of] natural gas combustion turbines that would be purchased to provide capacity have a levelized cost of energy of $ 0.194 / kWh and run 20 % of the year,

A conventional natural gas combustion turbine of the required size might require approximately $ 195 million in overnight capital costs (given the cost assumptions used in EIA's Annual Energy Outlook).

Investment in natural gas combustion could delay investment in non-fossil energy.

Natural gas combined cycle (NGCC) power is more expensive than both, ranging from 6.5 to 7.7 cents / kWh, and natural gas combustion turbines (NGCT) ranges from 15.7 to 19.2 cents / kWh.

Similar to residential and commercial activities, emissions from the industrial sector also come primarily from electricity generation and natural gas combustion, as the chart below illustrates.

That is, greater ghg emissions reductions are needed to prevent 2 °C warming than those that can be achieved by switching from coal to natural gas combustion.

Two controversies about the efficacy of switching from coal to natural gas combustion in the production of electricity need to be resolved before conclusions on the beneficial effects of natural gas in reducing ghg emissions can be made.

While a great deal of the energy liberated from natural gas combustion is from formation of water by uniting hydrogen with oxygen, in coal, much of the energy liberated is from oxidation of carbon.
