Green hydrogen gaining traction

绿氢或成未来首选燃料

Hydrogen has taken off this year as the future green fuel of choice, with governments and businesses betting big that the universe's most abundant element can help fight climate change.

氢在今年成为首选的未来绿色燃料，各国政府和企业都断定这种宇宙中最丰富的元素可以帮助应对气候变化。

More than $150 billion worth of green hydrogen projects have been announced globally in the past nine months.

过去9个月里，全球宣布了总额超过1500亿美元（约合人民币9830亿元）的绿氢项目。

In total, more than 70 gigawatts of such projects are in development, which could require $250 billion in investments by 2040, research firm Rystad Energy estimates.

据挪威吕斯塔德能源公司估计，总共有超过70吉瓦的此类项目正在开发之中，到2040年可能会需要2500亿美元的投资。

Green hydrogen, which is produced using electricity from renewable resources, could be the key to curb our carbon footprint.

绿氢即利用可再生能源电解水制成的氢，可能在人类控制碳足迹的过程中发挥关键作用。

But today, 99% of hydrogen is still made using fossil fuels, usually through a pollution-heavy process.

但直至今日，99%的氢的制作过程仍然需要使用矿物燃料，通常会造成重污染。
