LNG Energy: Bridging the Gaps in Green Fuels Adoption

As energy transitions accelerate, LNG’s adaptability will be pivotal in both immediate decarbonization and future integration of sustainable fuels. – Pinkesh Shah, Energy, Chemicals, and Materials Business Leader, Stellarix

In the last one and a half years, the energy industry has turned its focus back to petroleum-based liquefied natural gas. The accelerating transition of the global energy sector towards sustainability underscores some major challenges with alternative fuels, including ethanol, methanol, diesel, bio-LNG, and HFOs. Grey LNG has emerged as a “bridge fuel” between emerging green fuels and traditional fossil fuels. It leverages its established advantages to balance the technological, economic, and infrastructural challenges associated with its green counterparts. For instance, the recent extension of 45V by the US Senate has brought the fossil industry back into focus. Also, exploration & industry-wide expansion of Shale gas and LNG are expected to dominate the market for at least the next 5 years, as prices favor these fuels.

This article examines the current edge of fossil LNG energy, recent market shifts, and the strategic role it will play in accelerating industrial and maritime decarbonization. 

The Promise of Green Fuels and Gaps – How LNG is Filling the Gap?

Diesel and Heavy Fuel Oil (HFO)

HFO is a highly disfavoured fuel option for its high sulfur content, stringent emissions regulations, and reputational drawbacks. Also, switching to HFO offers limited decarbonization benefits as compared to other renewable fuels. Diesel, on the other hand, is cleaner than HFO but faces several headwinds, including rising costs, regulatory restrictions, and carbon inefficiency. 

Bio-LNG

Despite being chemically identical to fossil LNG, bio-LNG lags behind its non-renewable counterpart. Feedstock scarcity, fragmented logistics, and methane leakage are some of the most notable factors in this category. Agricultural residues run nearly half of the bio-LNG market; however, they take a back seat to broader biofuels, which leads to frequent shortfalls and delays. Limited production scalability and methane leakage during production counter the carbon credits earned by this biofuel. Lastly, supply chain disruptions and rising regulatory complexities push it back. For instance, the “greened” LNG, i.e., fossil gas + certificates, costs 40% less as compared to onsite bio-LNG, inclining the scales of economics more in its favor despite perpetuating dependence on fossils.
