“…This impact can be 34 reduced improving manufacturing process, but also recycling of the materials at the end of the life of the battery. This is confirmed by another study [49], which considers more Li-based chemistries: the 1 production of the cathode and anode materials represents a significant slice on the impact of the 2 whole battery, in particular because of the use of metals like chromium, cobalt and nickel. Another energy is used only for the fuel cell, and they do not contribute to the energy storage for the house.…”

“…Many studies have been published that report life cycle approaches to the hydrogen production process. For example, life cycle inventory (LCI) analyses have been published that calculate the life cycle GHG emissions for hydrogen produced from steam reforming of NG [27][28][29][30][31][32], coal gasification [29,31,32], and renewably powered electrolysis of water [30][31][32][33]. Specifically, Kato [34] took an economic approach and estimated the final cost in Japan of hydrogen produced in South Australia, Norway and the Middle East.…”

“…Ammonia production for fertilizer accounts for 2-3% of the total global energy consumption 4 , so the use of methanation to purify the hydrogen stream represents an enormous global energy loss. The US National Renewable Energy Laboratory estimates 11.9 kg of CO 2 equivalents are produced for every kilogram of H 2 produced 5 . Consequently, to prevent the (estimated) loss of 1.2 million tons of H 2 used in methanation would eliminate the release of 15 million tons of CO 2 equivalents annually.…”
