And a range of technological advances — from hydrogen fuel cells to compact fluorescent bulbs — suggests that a low-carbon future need not require surrendering a high quality of life.

一系列技术进步——从氢燃料电池到节电型荧光灯泡——预示着将来对低碳的需求并不会牺牲掉生活的高质量。

Fuel cell vehicles belch out none of the greenhouse gases blamed for global warming, but their high cost and a lack of hydrogen refueling stations pose obstacles to mainstream use.

燃料电车交通工具不会施放引起全球变暖的温室气体，但他们昂贵的价格和氢气站的不足成为进入普通消费者的障碍。

One of the biggest issues with hydrogen fuel cells, aside from the lack of fueling infrastructure, is the high cost of the technology.

作为当今氢燃料电池的一大瓶颈，不仅是燃机的普及，更是其高昂的成本。

This is mainly due to the high levels of risk and uncertainty that come with new tech: private firms would generally rather seek out low-risk, low-cost alternatives (i.e. more efficient internal processes or capital goods) than to invest time and effort into developing high-risk, initially-high cost alternatives (i.e. hydrogen fuel cells).

But in 1913 one of its scientists, Friedrich Bergius, found a way to turn coal into a high-grade liquid fuel by heating it in the presence of hydrogen and a catalyst.
