The technology group Wärtsilä on Thursday (24 March) said it has published an important paper on the role of sustainable bunker fuels in the energy sector’s transition towards decarbonised power generation.

Future carbon-neutral marine fuels and the use of flexible engine power plants capable of utilising such fuels, will be central to this transition.

Along with the growing need to decarbonise engine power plants, Wärtsilä has invested heavily in the study of alternative future fuels at its dedicated fuel laboratory where a broad range of fuels have been tested.

As part of the company’s new world-class Smart Technology Hub, fuel testing and the assessment of engine compatibility will uniquely be able to be carried out under one roof.

“Wärtsilä has taken a leading position in the study of carbon-neutral fuels, made possible by our outstanding facilities, testing capabilities and expertise,” explains Jukka Lehtonen, Vice President, Technology & Product Management, Wärtsilä Energy.

“This paper explains in great detail the options and likely future fuel-choice scenarios that will transform the way that energy is produced with assets such as grid balancing engines.”

The fuel options are broken down into three categories, namely Power-to-X (P2X), Bio-to-X (B2X) and Waste-to-X (W2X).

P2X fuels are produced through the electrolysis of water into hydrogen and its various derivatives. They can be considered ‘green’ only if the power used for the process is from renewable energy sources.

B2X includes biofuels and biogas which, particularly as blends, will likely be used in certain areas of the world as a locally suitable solution.

W2X fuels include plastic or tyre pyrolysis oils or gasified municipal waste. Since they support a circular economy, they have value for sustainability and decarbonisation.

Reetta Kaila, Director, Sustainable Fuels and Environment, Wärtsilä Energy, says: “The key outcome of our studies is that different fuels will be adopted depending upon location and availability.”

“We feel that we must look beyond the concept of one or two fuels, be it hydrogen, ammonia or methanol, being the universal choice. We believe that multiple fuel options will be available, many of them very localised serving power plants within fairly short distances of the fuel production.”

Fuel flexibility and enabling the increased adoption of solar and wind power will undoubtedly be major factors in the industry’s path towards 100% renewable energy systems.

Towngas x Royal Vopak MT

Hong Kong and China Gas Company Limited (Towngas) and Vopak China Management Co., Ltd. (Royal Vopak) on Tuesday (8 July) said both recently signed a strategic framework cooperation agreement to collaborate in areas such as green methanol production, storage, bunkering, and trading etc.

Focusing on the Chinese mainland, Hong Kong, and Asia-Pacific markets, both parties are joining forces to expand an efficient green methanol supply chain network and support the shipping industry’s low-carbon transition.

The two parties will capitalise on their respective strengths to expand the supply network of green methanol.

Towngas employs proprietary technology to convert agricultural and forestry waste as well as scrap tyres into green methanol, and has obtained multiple international certifications and provides a sufficient supply of green methanol for maritime fuel bunkering.

Royal Vopak provides green methanol storage and terminal services with its comprehensive storage and terminal infrastructure and coastal port network advantages.

Together, the two parties will achieve efficient resource allocation and ship green methanol to the Greater Bay Area, East China, South China, and the broader Asia-Pacific markets, further expanding the green methanol supply chain network.

Towngas and Royal Vopak will further develop multiple areas of regional cooperation, including in the Greater Bay Area. By leveraging the strengths of the ports in Hong Kong, Shenzhen, and Guangzhou, the partnership will focus on “production and storage synergy” as its core to strengthen cooperation around logistics and terminal facility construction, and to build an integrated green methanol storage and transportation network.

In East China, the two parties will centre their collaboration in Shanghai and Ningbo, two major international ports, to further strengthen cooperation in logistics storage and bunkering facility construction to meet the growing demand for green fuels at both ports.

In the Bohai Bay region, with Tianjin as the strategic hub, Towngas will transport green methanol produced at its northern China production base to Royal Vopak’s local storage tank farm, then achieve resource allocation through the Royal Vopak’s distribution network, supporting the supply of green methanol from northern China to the national and Asia-Pacific markets.

The two parties will also target key export markets, such as Singapore, Vietnam, Japan, and South Korea, to accelerate overseas expansion and boost the market competitiveness of clean energy in the Asia-Pacific region.

“Towngas has recently completed a 6,000-tonne green methanol bunkering project, the largest in Asia,” said Sham Man-fai, Towngas Chief Operating Officer – Green Fuel and Chemicals.

“It was completed with the support of Royal Vopak’s Tianjin storage tank farm facilities, laying a solid foundation for this partnership.

“Towngas’s Inner Mongolia green methanol plant is set to increase its annual capacity from 100,000 tonnes to 150,000 tonnes by the end of this year, with plans to further expand to 300,000 tonnes by 2028.
