A joint European / Japanese research project aims to lower the energy requirements and costs for manufacturing green methanol, the future fuel of choice for Maersk and one of the leading candidates for decarbonizing deep-sea shipping. 

Methanol can be synthesized from carbon dioxide and hydrogen at high temperature, then converted to methanol for use as fuel. If the carbon comes from CO2 capture and the hydrogen feedstock is produced using renewable power, the product - green methanol - is considered a net-zero fuel.

However, it takes a lot of energy to make. CO2 is a stable, unreactive molecule, and it takes a push (a catalyst and a lot of heat) to get it to react with hydrogen. In 2018, researchers at Penn State found a way to do it using a palladium-copper catalyst at a relatively cool temperature of 350-480 degrees Fahrenheit, but this is still quite hot. Maintaining that kind of temperature requires industrial scale heating, which raises energy consumption and cost of production.

The Laurelin project, a four-year international research initiative, hopes to cut that cost down. Its experts hail from Belgium, Germany, Japan, Netherlands, Spain and the United Kingdom, and they are combining their efforts to survey multiple combinations of catalysts and reaction chambers in search of the best arrangement. 

"Reducing the e-methanol production costs would lead to an increase in the opportunities to use it as fuel. This would directly benefits society thanks to the reduction in GHG emissions and costs, creating further jobs and wealth," explained Professor Teruoki Tago of the Tokyo Institute of Technology.

The team will test out more than 100 different catalyst materials and three reactor technologies (microwave heating, magnetic induction and plasma induction). "Catalysts are the key for methanol to become the main product, minimising the production of undesired complex mixtures," explains Adolfo Benedito Borrás, head of technical coordination for the project.

If successful, the Laurelin project's efforts would complement the push for higher efficiency in green hydrogen production, and would help expand the availability of green methanol for shipping. 

The initiative has about $4.8 million in funding from the EU and additional funding from Japan.

As shipping pursues decarbonization goals, carriers are increasingly adopting biofuels as a clean alternative to fossil fuels. MSC, CMA CGM and Hapag Lloyd are among the carriers that have recently launched initiatives to expand their use of biofuels. However, calls are growing - especially in Europe - for governments to put a moratorium on use of biofuels until the world averts hunger crisis. Following the blockade of Ukrainian ports by Russia, some developing nations are now facing the threat of...

Another one of the classic cruise ships which helped to lay the groundwork for today’s billion-dollar industry has reached the end of its long career. Introduced in 1977 as Cunard Line’s Cunard Princess, the diminutive 17,500 gross ton cruise ship holds a unique place as the last of the first generation of modern ships. She survived for 45 years, outliving nearly all of her contemporaries, and now joining others at the breakers' yards. The 537-foot-long cruise ship was ordered in...

One of the technologies that are being actively explored seeks to combine offshore wind farms with the production of hydrogen. In the latest development, Germany’s energy giant RWE announced working with its partners it plans to explore the production of hydrogen at sea linked to one of the offshore wind farms it has slated for construction. The company announced this week that due to the innovative nature of the project it is one of 17 that has been pre-selected by...

[Brief] Indonesian rescue agency Basarnas has helped remove the remains of a seafarer who was killed in a crane accident aboard a bulker in the Indian Ocean.  The victim, identified as Philippine national Crispin Cadiz, was working aboard the bulker Lowland Comfort. On July 4, he was hit by a crane and severely injured. Despite attempts to treat him on board, he succumbed to his injuries.  The Lowland Comfort continued on her commercial journey, and when she reached the Bay...
