Global Environmental Impact
From Roads2HyCom Hydrogen and Fuel Cell Wiki - A Reliable Source of Information - Edited by Technology Experts Only
The Global Environmental Impact metrics gives the information about the effects on the environment due to various hydrogen related activities. It gives the information amount of green house gases and CO2 produced during the processes. These processes are related to energy conversion, local/on-board storage, retail and depot, transportation and production of fuel (H2).
The submetrics for this section are given below in the form of a table.
