Circular Economy / The Crunch in Maritime Fuel?

This report is brought to you by Sustainable Circular Economy, a boutique firm in Vancouver, Canada, dedicated to assisting companies to to do the world a world of good by focusing on real sustainability and the circular economy that considers life-cycle impacts on people, the planet and profitability.

A major concern is, “What’s the Plan for sustainability if the pronouncements do not work out?” Transiting to the use of hydrogen as a sustainable fuel is not an easy task, but many people talk as if it is easy to move from fossil fuels to alternate, environmentally friendly fuels.

Don’t get me wrong; I am not an antagonist for “not switching to environmentally sustainable solutions.” I am deeply concerned that we get this right – we have one chance and I ask the question, “What is the Plan for sustainability if the pronouncements do not work?”

In it report on the use of potentially sustainable alternatives for the offshore shipping industry, DNV, a global leading quality assurance and risk management company operating in more than 100 countries has ruled out the use of pure hydrogen as a clean fuel for international shipping.

Why Is Hydrogen Ruled Out as a Sustainable Fuel?

Because of its poor energy density and other challenges, not the least being safety. They suggest that pure hydrogen will not be in the forefront of the shipping industry’s 2050 plans, losing out to biofuels, fossil fuels and hydrogen derivatives. They categorize hydrogen as unsuitable for use as a shipping fuel.

The Problems with Pure Hydrogen as a Sustainable Fuel?

Liquid hydrogen requires cryogenic temperatures of below minus 253°C, making it difficult to handle and store at sea.

And compressed and liquid hydrogen have poor volumetric energy density of 1.2kWh and 2.4kWh per litre, respectively, meaning that huge storage tanks would be required to ship and burn it over long distances, in a setting where space is at a premium.

Are there Alternatives for Sustainable Fuels?

There are and DNV has suggest 24 alternatives that may work. They suggest a full decarbonization scenario, biofuels, synthetic fuels made with biomass such as bio-marine gas oil (bio-MGO), bio-LNG and bio-methanol, would take a sizeable share of the fuel mix across the board of variables.

They also suggest that green hydrogen-derived fuels, such as ammonia, methanol, e-LNG or e-MGO make a contribution in scenarios where biomass or CCS availability is limited, or where renewable electricity is abundant and cheap.

Most importantly too, they emphasize that all novel alternative fuels would have to contend with heightened safety considerations and nascent regulation, especially hydrogen, which has a high flammability rate, and ammonia and methanol which are both highly toxic
