Natural Gas Use to Reduce Carbon, Greenhouse Gases
BP – BP achieved zero net growth in operational emissions in 2018, a methane intensity of 0.2% and 2.5 million tonnes (MTe) of sustainable GHG emissions reductions activity since the beginning of 2016.
Chevron – Chevron has set a goal to reduce flaring by 25 to 30% and to reduce methane emissions by 20 to 25% for the 2016-2023 time period. These new performance measures can be used to determine Chevron’s annual variable pay program that affects approximately 45,000 employees. Examples of emission reduction projects:
Richmond Refinery modernization project’s annual NOx reductions are equivalent to removing more than 11,000 cars from Richmond streets;
Air emission monitoring at the Richmond, California refinery provides real-time 24-hour data about air quality in the community.
ConocoPhillips – ConocoPhillips has set a goal to reduce its GHG emissions intensity from 5 to 15% by 2030. Examples of emission reduction projects:
In the Bakken, ConocoPhillips uses natural gas chillers to enable more natural gas to be the correct temperature in order to be eligible to go into the midstream pipeline, this way less natural gas will be flared;
ConocoPhillips sponsors a Carbon Prize Competition: money is given for research on technologies that convert CO2 into valuable products.
EQT – Uses compressed natural gas (CNG) in company vehicles to reduce emissions. EQT also captures natural gas from the field to power fuel cells, which generate on-site energy.
In Norway, Equinor is further reducing emissions by exploring opportunities for electrification of its offshore fields Troll C, Sleipner and Gudrun, which could potentially reduce CO2emissions by more than 600,000 tonnes per year.
In fact, Shell executives’ pay is now linked to this target.
Shell has laid out a plan for meeting the goal of the Paris Climate Agreement in Sky, a technologically and macro-economically possible route to achieving the goals of the Paris Agreement.
ExxonMobil – ExxonMobil is using natural gas as a pathway to significant reductions of greenhouse gases in industrial operations.
At its refinery in Antwerp, Belgium, co-generation technology is being used to improve energy efficiency at an industrial scale. The refinery makes products such as like low-sulphur fuel for ships and uses a natural gas turbine to power the operations. The process of making electricity with the turbine generates two things: electricity and heat. Ordinarily, the heat would be wasted, but by putting a specially designed turbine right next to the refinery’s distillation facility, the company is able to make use of that heat in several ways – to operate pieces of machinery and super heat crude oil during refinery.
Shell – Shell uses natural gas to lower its GHG footprint and significantly reduce air pollution. Examples of how Shell uses natural gas:
