一些专家认为,在石油和天然气储量用完之后,氢气可能会成为理想的燃料。然而,科学家们长期以来一直面临着一个难题,这就是必须找到一种低成本生产氢气的方式。最近,科学家在这方面取得了进展。他们说,或许可以从绿色藻类中找到解决这个问题的钥匙。今年2月,一些科学家在美国科学促进会举行的一次全国会议上指出,绿色藻类是遍布世界各地的简单植物,而绿色藻类具有把水和阳光转化为氢气的特殊功 Some experts believe hydrogen may be the ideal fuel after oil and gas reserves have run out. However, scientists have long been facing a problem that must find a way to produce hydrogen at low cost. Recently, scientists have made progress in this area. They say it may be possible to find the key to solving this problem from green algae. In February of this year, some scientists pointed out at a National Conference sponsored by the American Association for the Advancement of Science that green algae are simple plants spread all over the world, while green algae have a special function of converting water and sunlight into hydrogen
