Green Ammonia To Solve Hydrogen Transportation Conundrum
New green ammonia project aims to connect green hydrogen dots.The dream of a global economy powered by renewable hydrogen is coming into sharper focus, except for one key sticking point. Getting hydrogen from one place to another adds costs. Energy loss is also an issue. An inexpensive, efficient, and sustainable transportation medium would fill the gap, and apparently green ammonia is first in line.The US Department of Energy is among those eyeing ammonia for improving the cost-efficiency of.
“Liquid hydrogen tankers are cheaper, but there is a considerable energy and cost penalty associated with liquefaction ,” the Energy Department observed.To overcome these obstacles, the Energy Department favored the carrier approach, in which hydrogen is transported as an element in another medium, then extracted at its use point.
“Ammonia is one of the only materials that can be produced cheaply, transported efficiently and transformed directly to yield hydrogen and a non-polluting byproduct,” they concluded.There is nothing particularly green about the ammonia-as-a-carrier approach when the vast majority of the global hydrogen supply comes from natural gas and other fossil resources. However, the script has flipped in recent years.
