How to make hydrogen straight from seawater – no desalination required. The new method from researchers splits the seawater directly into hydrogen and oxygen – skipping the need for desalination and its associated cost, energy consumption and carbon emissions.

Your yourself brought up the idea of short term usage hydrogen generation/storage, because of storage issues. I responded that the energy density advantage of hydrogen over batteries is largely moot in that situation because the storage is such a small portion of the weight of the system. You reiterated the importance of energy density in ling term storage solutions like EVs, ignoring the point I made.

This is tiresome. You're just typing things, you can't even keep track of what YOU have already said.

I'm gonna run it back for you one more time, but thats the end of it.

1. Storage issues surrounding hydrogen embrittlement etc. we're raised.
2. You suggested that short term usage generation of hydrogen would work because it doesn't require long term storage.
3. I replied that the energy density advantage that hydrogen holds over batteries is not as important with that style of system has smaller storage requirements, therefore the energy density of the storage is not as important as the round trip efficiency.
4. You replied that energy density is extremely important for long term storage.

Number 4 is the problem. You didn't address my response to your statement, you just shifted topics and discussed the importance of energy density in a different context from the one THAT YOU SUGGESTED.

If this response doesn't make things clear enough for you, i apologize, but I won't be replying to you anymore.
