One approach to carbon-neutral fuel is to capture carbon dioxide from the atmosphere and combine its carbon with the hydrogen in water.

生产碳中和燃料的一种方法是从大气中捕获二氧化碳，再将其中的碳与水中的氢结合。

They have chloroplasts, that combine carbon dioxide and water, with light energy from the sun, to create oxygen and sugar, a form of chemical energy.

植物细胞有叶绿体，可以结合二氧化碳和水，只要有来自太阳的能量，就可以制造氧和糖，这属于化学能量。

This uses renewable energy to pull carbon from the air, combine that carbon with hydrogen, and then uses that to power our aircraft.

它使用可再生能源从空气中提取碳，将碳与氢结合，然后用它为我们的飞机提供动力。
