Are future fuels better for the environment? All future marine fuels – LNG, ammonia, biofuels, methanol and hydrogen, to name the main contenders – reduce carbon emissions from shipping. How environmentally friendly they are depends on how they are produced. A lifecycle approach to ship-generated emissions takes the entire value chain of the energy source “from well to wake” into account. This includes the energy related to production and logistics of the fuel in addition to the emissions created by combustion onboard.
Colours are used to denote the sustainability of different production routes. For example:

Hydrogen, the simplest element, sits at the beginning of the periodic table and is commonly utilised in its gaseous form H2. It has sent crews and cargo into space and today is used to power cars and other land-based vehicles. But could hydrogen be the fuel for the future of shipping? Liquefied hydrogen has already been transported by ship, but not used as a fuel onboard. What are its pros and cons, and what is the status of marine hydrogen engine technology?
If you’re curious about the current state of play and future outlook, Hydrogen – Fuel for thought in our Q&A has everything you need to know.
New future fuels in shipping are being developed all the time. They include bio and synthetic liquefied natural gas (LNG) as well as ammonia, methanol, hydrogen and biofuels.

Liquefied natural gas (LNG) is natural gas that has been cooled down to -162ºC (-260ºF). Cooling the gas reduces its volume significantly, making it easier and safer to transport and store. Today LNG is a well-established maritime fuel that has been adopted across a variety of vessel segments. No surprise given that it can help you reduce greenhouse gas emissions significantly and provides an excellent platform for other future fuel options too. Why is it such an attractive prospect, and how is the critical issue of methane slip being addressed?
For answers, look no further than LNG – Fuel for thought in our deep-dive Q&A, which will help you to weigh up what LNG has to offer and what you need to take into account when considering it as an option.
One of the challenges with LNG is methane slip – the small amount of the fuel that doesn’t burn in the engine and escapes with the exhaust gases instead. How to be smarter about methane slip – right now will help you discover simple solutions that can bring results quickly.

Which future fuels are renewable?
Renewable fuels are produced from renewable resources. For example, biofuels produced from vegetable oil, methanol produced using clean energy, hydrogen produced using renewable processes and synthetic fuels (electrofuels, or eFuels for short) produced from captured carbon dioxide and water. Wikipedia has a useful roundup on the subject.
eFuels are part of a wide range of new future fuels in shipping that are being developed all the time. You can learn more about them on the eFuel Alliance website.
When you’re weighing up your future fuel options, volumetric energy density is an important consideration. It’s defined as the amount of energy contained in a fuel per unit volume.
Essentially, the lower the volumetric energy density, the more volume of fuel you’re going to need to store and use onboard to do the same amount of work. Ammonia, for example, has a lower volumetric energy density than LNG
