FRANKFURT, Dec 17 (Reuters) - Sentiment in the market

for green hydrogen, which has been hit by project delays and

cancellations due to regulatory uncertainty in the U.S. and

Europe, remains good, the CEO of Thyssenkrupp Nucera

said on Tuesday.

"I think it's fair to say that the mood in the market

remains optimistic and the hydrogen industry is actually ramping

up," Werner Ponikwar told analysts after presenting full-year

results, still cautioning that "existing challenges in the

market will not disappear overnight".
