“…It is noted that catalyst formulation consisting of high palladium loading has shown significant improvements in CH4 reduction for lean-burn engines, but are susceptible to catalyst destruction due to higher exhaust water content and possible sulphur poisoning [31,32]. The oxidation of methane is highly dependent on exhaust gas temperature [33]. Early work by WVU examined dual fuel operation of on-road dual fuel engines utilizing technology similar to current off-road dual fuel kits.…”

The process of unconventional natural gas recovery is becoming increasingly popular as the world's demand for alternative fuels continues to grow. Natural gas has the potential to be a widely used fuel in the near future due to its availability and potential to displace petroleum-based liquid fuels. As energy companies extract natural gas, current fuels, such as diesel, are consumed in mass quantities for drilling and hydraulic fracturing operations. In order to save on costs and in an attempt to reduce emissions, many companies are investing in dual fuel and dedicated natural gas engines to power operations. This trend results in new sources of methane emissions, which can contribute significantly to global warming. West Virginia University is aware of the potential impact of these emissions and is conducting research funded by the Department of Energy to assess methane emissions from dual fuel and dedicated natural gas technologies, as industry moves towards more extensive use of natural gas as a fuel for onsite power production. Unconventional Natural Gas PotentialThe recovery of unconventional natural gas is a growing industry in the United States (US) and around the world. As high-energy demands become a prevalent issue worldwide, the search for cheaper and cleaner alternative fuels becomes more critical. Natural gas is an option that is now becoming more widely available due to advances in the technologies required for its recovery. These technologies include horizontal drilling and hydraulic fracturing. According to the Energy Information Administration (EIA), there is as much as 1,193 trillion cubic feet of natural gas in the US that is capable of being recovered from unconventional sources [1]. The extraction of this natural gas results in high-energy demands and using natural gas as a fuel to power these operations leads to new sources of methane emissions. The three main sources of methane emissions include leaks and losses from onsite fueling equipment, methane vented from the crankcase, and uncombusted methane in the engine exhaust.
