Which of the following statement is false?

参考解析：

细节理解题。根据第一段第一句“Hydrogen has taken off in 2020 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.”可知，各国政府和企业纷纷押注，认为宇宙中最丰富的元素有助于应对气候变化，Hydrogen即the universe’s most abundant element，所以A项、C项正确；根据第一段第二句“More than $150 billion worth of green hydrogen projects have been announced globally in the past nine months”可知，在过去的9个月中，全球宣布了价值1500多亿美元的绿色氢项目，所以B项中的“Over $250 billion”错误；根据最后一段最后一句“in processes that emit 830 million tons a year of carbon dioxide, according to the International Energy Agency”可知D项正确。故选B。
