煤、石油、天然气等能源在地球上已探明的蕴藏量是有限的,从人类目前利用这些能源的消耗速率估算,石油和天然气不过几十年,煤不过几百年就会消耗殆尽。因此,进一步开发利用新能源(核能、太阳能、风能、水能、地热能、潮汐能等)已显得十分迫切。 氢气是一种高效而无污染的理想能源。下列(1)~(6)是某化学兴趣小组的学生查阅资料归纳的工业上制取氢气的方法,其中包括正在研发的方案。

(1)电解法:

(2)甲烷转化法:

(3)水煤气法:

(4)碳氢化合物热裂法;

(5)设法将太阳光聚焦产生高温使水分解:

(6)寻找高效催化剂使水分解产生氢气。

如果人类将广泛使用氢气作为能源,那么上述6种方法中你认为可行的、且很有发展前途的方法是哪几种?并逐条说明理由。
