根据挪威顾问DNV在其新的氢预测2050年，必须大量增加可再生能源的支出增加，以及在本世纪晚些时候产生所需的氢气。

Hydrogen will account for 0.5% of the global energy mix by 2030, rising to 5% mid century, says the firm's report. To meet greenhouse gas reduction targets set in the Paris Agreement, hydrogen production would need to reach 15% by 2050, it adds.

环境ally cleaner green hydrogen, powered by renewable energy, will account for 72% of global output by 2050, forecasts DNV. This will require 3,100 GW of surplus renewable capacity, which “is more than twice the total installed generation capacity of solar and wind today," it notes.

Blue hydrogen, which is produced from natural gas with emissions captured, will account for 30% of total production in 2030. “But its competitiveness will reduce as renewable energy capacity increases and prices drop,” DNV contends.

到2050年，全球用于氢生产的支出将总计6.8万亿美元，另外1,800亿美元投资了管道。超过50％的全球氢管道将从天然气分布中重新利用。

“Policies do not match hydrogen’s importance,” sayss Remi Eriksen, DNV president and CEO. “They will … need to support the scaling of renewable energy generation and carbon capture and storage as crucial elements in producing low-carbon hydrogen.”
