Energy systems are undergoing rapid change as the world responds to climate change.
Many policymakers may ask, what will be the next great energy source for a low-carbon
future? All indications so far point to hydrogen energy. Although it is anticipated that costs
will likely fall as the hydrogen production scale increases, it may be reported that the high
technology costs remain a barrier to the widespread shift towards hydrogen. This paper
presents hydrogen production costs for various production methods for different regions …
