Why Not Use Water Electrolysis for Industrial Hydrogen Production?

AI Thread Summary
Water electrolysis for industrial hydrogen production is limited primarily due to high electricity costs, making it less economical compared to hydrogen production from natural gas, light oil, or coal. Currently, only 4% of hydrogen is produced via electrolysis, highlighting its low adoption in the industry. Despite the abundance of water, the economic viability of alternative methods remains a significant barrier. Resources such as the U.S. Department of Energy and various reports provide further insights into hydrogen production methods. Overall, the current energy landscape favors fossil fuels over electrolysis for hydrogen generation.

If water is so plentiful in Nature, why to not use its electrolysis in industry to obtain hydrogen?

Electricity costs money and at the moment it is much cheaper to produced hydrogen from natural gas, light oil or coal, with only 4% by electrolysis.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
