中国石化新闻网讯 据能源世界网3月12日墨尔本报道，一个试验项目发起人周五表示，一家日澳合资企业已开始在一个耗资5亿澳元（合3.87亿美元）的试验项目中用褐煤生产氢气，该项目旨在证明可以安全生产液化氢并出口到日本。

在日本和澳大利亚政府的财政支持下，日本川崎重工(Kawasaki Heavy Industries)正在维多利亚州运营这一试点项目。维多利亚州拥有全球已知褐煤储量的四分之一。

 该项目是帮助日本实现2050年净零碳排放目标的关键。

与此同时，澳大利亚正在努力成为一个主要的氢出口国，最终将与其在全球液化天然气(LNG)贸易中的主导地位相抗衡，这可能会为其煤炭和天然气提供一个更加绿色的市场。

由于其相对较低的能量含量，棕色煤被认为是最低等级的煤炭。长期以来，棕色煤一直是澳大利亚一些污染最严重的发电站的燃料，其中一些发电站已经关闭或即将关闭。

该项目是通过煤与氧气和蒸汽在高温高压下反应产生氢气，过程中还会产生二氧化碳和其他气体。

KHI此前曾表示，如果该项目商业化，计划将把二氧化碳埋在维多利亚海岸附近。澳大利亚和维多利亚州政府正在进行一个平行的项目，测试在海底输送和注入二氧化碳。

该试点项目生产的氢气将被运输到一个港口，在那里液化后出口。

下一个重大步骤是用KHI建造的世界上第一艘液化氢运输油轮运送货物。由于新冠疫情的限制延缓了对油轮的最终检查，航程被推迟到年中。

KHI的氢工程澳大利亚分公司的Hirofumi Kawazoe在一份声明中表示，当2021年年中开始运输液化氢时，全世界的目光都将聚焦在维多利亚。

该项目在澳大利亚方面的合作伙伴包括日本电力开发公司(J-Power)、Iwatani公司、Marubeni公司、住友公司和澳大利亚AGL能源有限公司，后者的煤矿正在供应褐煤。

In Australia, Japanese start producing hydrogen from brown coal

A Japanese-Australian venture has begun producing hydrogen from brown coal in a A$500 million ($387 million) test project that aims to show liquefied hydrogen can be produced and exported safely to Japan, the project sponsors said on Friday.

    Japan's Kawasaki Heavy Industries is running the pilot project with government financial support from both Japan and Australia in the state of Victoria, home to a quarter of the world's known brown coal reserves.

The project is key to helping Japan meet its target of net zero carbon emissions by 2050.

At the same time, Australia is pushing to become a major hydrogen exporter, eventually rivaling its dominance in global liquefied natural gas (LNG) trade, which could potentially give it a greener market for its coal and gas.

Brown coal is considered the lowest rank of coal due to its relatively low energy content and has long fueled some of Australia's dirtiest power stations, some of which have already shut or are slated for closure.

The project is producing hydrogen by reacting coal with oxygen and steam under high heat and pressure in a process that also yields carbon dioxide and other gases.

If the project goes commercial, the plan would be to bury the carbon dioxide off the coast of Victoria, KHI has previously said. The Australian and Victoria state governments are running a parallel project to test transporting and injecting carbon dioxide under the seabed.

The hydrogen produced in the pilot project will be transported to a port site where it will be liquefied for export.

The next big step will be to ship a cargo on the world's first liquefied hydrogen carrier, built by KHI. The voyage has been delayed to mid-year, due to COVID-19 restrictions which have slowed final checks on the tanker.

"The eyes of the world will be on Victoria when shipments of liquefied hydrogen commence in mid-2021," Hirofumi Kawazoe, from KHI's Hydrogen Engineering Australia unit, said in a statement.

    Partners in the Australian side of the project include Japan's Electric Power Development Co (J-Power), Iwatani Corp, Marubeni Corp, Sumitomo Corp and Australia's AGL Energy Ltd , whose mine is supplying the brown coal.
