Study: ‘Challenging’ for LNG to meet 2050 emissions reduction target

30 Jan 2019

The Sustainable Gas Institute (SGI) at Imperial College London on Monday (28 January) released a 126-page whitepaper investigating the potential of liquefied natural gas (LNG) to reduce GHG and air pollution emissions from trucks and ships.

“Natural gas has been suggested as an alternative transport fuel to help combat these emissions, particularly in shipping and goods transportation due to the range requirements in these vehicle types,” it said.

“However, there is some disagreement as to the potential for natural gas to provide significant improvements over emissions emerging from the current transport system.”

In summary, the study Can natural gas reduce emissions from transport? Heavy Goods and Shipping concludes supply chain emissions, relatively lower efficiency in gas engines,
and methane emissions all reduce the emissions reduction potential of natural gas.

“The value of natural gas as a transport fuel in the future is therefore dependent on maximising the GHG and air pollution benefits it provides,” it states.

“The constrained level of emissions reduction available in natural gas engines also indicates the need for a wider range emissions reduction measures in order to meet longer term emissions reduction goals.

“The challenge is therefore to understand the extent to which natural gas can usefully contribute to emissions reduction, and also establish at what point in the future lower emissions fuels and energy vectors should be used to drive further emissions reductions.”
