comment:
in recent years, thanks to innovation and ip protection in hydrogen-related technology, china has caught up counterparts. at the same time, we should realize clearly that chinese companies should strengthen innovation in core technologies to overcome the current deficiencies, in storage and transportation，so as to seize the opportunity in the global market.
