In fact, worldwide, steelmaking is responsible for 5 percent of annual emissions.

实际上，每年炼钢所排放的温室气体占全世界总量的5%。

And metaphorically for industries ranging from steelmaking to pharmaceuticals, which use it in their processes.

就像，从钢铁业到制药业，这些行业在其生产过程中都要使用氧气。因此氧气的世界市场很大。

But they ended up buying just the steelmaking coal division.

但他们最终只收购了炼钢煤部门。

As a result, steelmaking accounts for 7-9% of the world's anthropogenic greenhouse-gas emissions.

因此，炼钢占世界人为温室气体排放量的 7-9%。

That point — steelmaking's massive carbon footprint — underlines just what a game-changer green hydrogen could be.

这一点——炼钢的巨大碳足迹——突显了绿色氢能改变游戏规则。

His most recent bruising experience came from his effort to stop ArcelorMittal, a steelmaking giant, closing two blast furnaces at Florange, in Lorraine.

他最近的受伤经历来自于他致力于停止阿赛洛米塔尔，钢铁巨头，关闭在洛林地区弗洛朗热的两个钢铁炉。

These include setting standards and grabbing a slice of potentially lucrative businesses such as software to control hydrogen- and steelmaking equipment.

其中包括制定标准，并从可能有利可图的业务中分一杯羹，例如控制氢和炼钢设备的软件。

Heating limestone generates about 60% of the sector's carbon emissions and a replacement technology, such as direct reduction in steelmaking, is lacking.

加热石灰石产生了该行业约 60% 的碳排放，并且缺乏替代技术，例如直接还原炼钢。

Also, nuclear power is the only efficient way to provide zero-carbon heat for high-temperature industrial processes such as steelmaking, which account for about a fifth of energy consumption.

核能是为高温工业过程（如炼钢）提供零碳热量的唯一有效途径，这一过程约占能源消耗的五分之一。

Green steelmaking is still in the first phase of this maturity " S-curve" , says Marc van Gerven, who advises big utilities and miners on the energy transition.

为大型公用事业公司和矿业公司提供能源转型建议的马克·范·格文 (Marc van Gerven) 表示，绿色炼钢仍处于这一成熟度“S 曲线”的第一阶段。
