據世界天然氣網3月29日消息 日本航運公司商船三井及其集團公司MOL Ferry完成了日本首次使用可再生柴油的大型渡輪海上試驗。

這兩家公司使用同胞生物技術公司Euglena銷售的可再生柴油對MOL ferry的渡輪Sunflower Shiretoko進行了海上試驗。

試驗在茨城縣的歐雷港進行。

據該公司稱，用于海上試驗的可再生柴油由生物質制成，可以在不改變傳統柴油動力船用發動機規格的情況下使用。

據說其符合硫排放規定，因為與目前普遍使用的重質燃油不同，該可再生柴油不含硫，硫是內燃機空氣污染的主要成分。

此外，該生物燃料在燃燒階段排放二氧化碳，但生物質原料在生長過程中通過光合作用吸收二氧化碳，因此當其被使用時，預期可以實現碳中和。

該試驗被視為朝著實現凈零溫室氣體（GHG）排放邁出的一步，這是MOL集團“環境愿景2.1”設定的目標，該目標闡述了該集團處理全球環境問題的方法。

更重要的是，在其倡議中，該組織支持Euglena的“日本綠色石油”宣言，該宣言旨在促進日本向生物燃料的全國性轉變，這次海上試驗是其中的一個關鍵因素。

雙方在一份聯合聲明中表示：“MOL和Euglena正在努力減少海運業的環境影響，實現可持續的全球社會，同時推進環?；顒?。”

Japanese trio tests renewable diesel-fueled ferry

Japanese shipping firm Mitsui O.S.K. Lines and its group company MOL Ferry have completed the country’s first sea trial of a large ferry using renewable diesel fuel.

The companies conducted the sea trial of the ferry Sunflower Shiretoko, owned and operated by MOL Ferry, using renewable diesel fuel marketed by compatriot biotechnology firm Euglena.

The trials took place in the Port of Oarai in Ibaraki Perfecture.

According to partners, the renewable diesel fuel used for the sea trial is made from biomass and can be used without changing the specifications of conventional diesel-powered marine engines.

It is said to comply with SOx regulations because, unlike the heavy fuel oil in general use today, it contains no sulfur, a major component of air pollution from internal combustion engines.

In addition, this biofuel emits CO2 at the combustion stage, but the biomass feedstock absorbs CO2 by photosynthesis in the growth process, so it is expected to achieve a carbon-neutral state—essentially net-zero CO2 emissions when it is used.

The trial is seen as a step toward achieving net-zero greenhouse gas (GHG) emissions, a target set by the MOL Group “MOL Group Environmental Vision 2.1”, which laid out the group’s approach to global environmental issues.

What is more, among its initiatives, the group supports Euglena’s “Green Oil Japan” declaration, which aims to promote Japan’s nationwide shift toward biofuel, and this sea trial was a key element of that.

“MOL and Euglena are working to reduce the maritime industry’s environmental impact and realize a sustainable global society while moving ahead with environment-friendly activities”, the parties said in a joint statement.
