light petroleum products

include liquefied petroleum gas (LPG), naphtha and gasoline.

liquefied natural gas (LNG)

liquidity

the ability to sell assets without significant movement in the price and with minimum loss of value.

low-carbon technologies

technologies that produce low – or zero – greenhouse-gas emissions while operating. In the power sector this includes fossil-fuel plants fitted with carbon capture and storage, nuclear plants and renewable-based generation technologies.

lower heating value

the heat liberated by the complete combustion of a unit of fuel when the water produced is assumed to remain as a vapour and the heat is not recovered.

l

lt
