But developers are split on whether efforts should focus on emissions-free green hydrogen or if blue hydrogen is necessary to bridge the gap and build out infrastructure. As climate predictions get more dire, the broad consensus is that scalable and economic clean-hydrogen solutions cannot come soon enough. While new opportunities to collaborate across sectors are helping get projects off the ground, insiders say greater effort is needed to incentivize both the production and consumption of low-carbon hydrogen. Various estimates see hydrogen accounting for about 12%-25% of total energy demand by 2050, essentially all of which will need to be produced through electrolysis powered by renewable electricity (green hydrogen) or through methane steam reforming combined with capturing and storing the resulting emissions (blue hydrogen). Today almost none of the more than 90 million tons of hydrogen produced globally comes from low-carbon sources.
