Methane emissions reduction using gas turbine technology The benefits of transitioning from diesel-powered to electric-driven pressure pumps powered by modular or trailer-mounted gas turbines

M ethane is responsible for around 30% of the rise in global temperatures since the Industrial Revolution, making emissions reductions of this gas fundamental for immediate action against global warming. What was once considered unavoidable waste is now recognised as a critical climate threat demanding immediate action. As governments and industry bodies across the world tighten environmental regulations, the emissions abatement market has been projected to reach $85 billion by 2030. Demand for cleaner power solutions that can handle the variable and unpredictable composition of flare gases is more important than ever before due to the rapid expansion of electric fracturing (e-frac) operations. Advanced gas turbine technology offers a game- changing solution, converting problematic Onshore oil Onshore gas Oshore gas Oshore oil

length of time they remain in the atmosphere and their ability to absorb energy. Methane is proven to have a much shorter atmospheric lifetime than carbon dioxide (CO 2 ), but absorbs much more energy while in the atmosphere. In fact, the Intergovernmental Panel on Climate Change (IPCC) consider methane to be 28 times more effective than CO 2 in terms of energy absorption over a 100-year period. This makes methane a critical target for efforts to mitigate climate change. The IPCC has indicated a global warming potential (GWP) for methane of 84- 87 when considering its impact over a 20-year timeframe and 28-36 when considering its impact over a 100-year timeframe ( IPCC, 2023 ).
