Shipping: Hydrogen or LPG?

How Hydrogen Could Help Clean Up the Global Shipping Industry
Paul Tullis Jan. 10, 2018

With their greenhouse gas emissions rising and regulations looming, shipping companies that transport nearly all of the world’s goods are looking at renewable fuel sources to power container ships.

The shipping industry is responsible for about 3 percent of global greenhouse gas emissions, according to the International Maritime Organization (IMO), and the European Commission estimates that its spew could grow between 50 percent and 250 percent by 2050. Yet the international climate accord hashed out in Paris in 2015 gave the industry a free pass, placing no requirements on the IMO, the body that regulates shipping, to reduce carbon emissions.

Nevertheless, the organization is working on a strategy to cut emissions, which it plans to unveil this year. If the IMO fails to come up with an acceptable plan by 2021, however, the European Union’s emissions reduction scheme will include shipping by 2023. IMO regulations go into effect in 2020 that will limit vessels’ sulfur emissions, a deadly byproduct of fossil fuels that’s found in particularly high concentrations in the cheap, lightly refined petroleum product known as bunker fuel favored

LPG As Marine Fuel: The World LPG Association Supports the Shipping Industry to Meet Emission RegulationsM/b>

Increasing concern over the impact of human activities on our environment is encouraging the maritime transport industry to move towards using alternative fuels on board ships as a prime source of energy for propulsion and electricity generation. This trend is being reinforced by national and international regulation, led by the International Maritime Organization (IMO), with its Emission Control Areas (ECAs).

As a consequence, ship owners who need to replace ships will be forced to think about a cleaner fuel, it is inevitable that there will be a radical change in shipping fuel options from HFO to cleaner alternatives. Amongst the options, LPG provides a future fit solution for shipping industry for the reduction of exhaust emissions from marine vessels. LPG as a clean and immediately available energy source. LPG emits practically negligible SOx and particulate matter. Moreover, it has the ability to emit approximately 80% fewer NOx emissions related to Tier I. Compared to existing heavy marine fuel oils, LPG’s greenhouse gas (GHG) performance represents a major step forward. With no methane slip problem LPG, realistic reductions of GHG by 20% are achievable, compared with conventional maritime fuels offering significant environmental advantages while meeting all energy and environmental challenges.

The World LPG Association (WLPGA), with its continued commitment to cleaner environment, has issued a report “LPG for Marine Engines – The Marine Alternative Fuel”, dedicated to the use of LPG in the marine sector.
