Develop blue hydrogen alongside green – study

Research led by Imperial College London shows green hydrogen is unlikely to meet demand at cost in near-term

Simultaneous development of green and blue hydrogen is vital if the world is to reach net-zero emissions by 2050, according to a study by an international team of researchers led by Imperial College London. Both blue and green hydrogen production have drawbacks. The potential of blue hydrogen as a low-carbon fuel is threatened by upstream methane leaks, while green hydrogen production is expensive and requires the use of rare metals that are not in abundant supply. Thinktank the Energy Transitions Commission estimates that 850GW of hydrogen production will be needed under a scenario where the world meets net-zero emissions by 2050. But current platinum production—even if entirely dedicated t
