Science wrote: Assessing ExxonMobil's Global Warming Projections

... Our analysis shows that, in private and academic circles since the late 1970s and early 1980s, ExxonMobil scientists (i) accurately projected and skillfully modeled global warming due to fossil fuel burning; (ii) correctly dismissed the possibility of a coming ice age; (iii) accurately predicted when human-caused global warming would first be detected; and (iv) reasonably estimated how much CO2 would lead to dangerous warming. Yet, whereas academic and government scientists worked to communicate what they knew to the public, ExxonMobil worked to deny it...

Indeed. And possibly a way to denude the Energy Charter Treaty t'boot.

Seawater split to produce green hydrogen
Posted on Feb 1 2023 by Jessica Stanley

Researchers have successfully split seawater without pre-treatment to produce green hydrogen.

The international team was led by the University of Adelaide’s Professor Shizhang Qiao and Associate Professor Yao Zheng from the School of Chemical Engineering.

“We have split natural seawater into oxygen and hydrogen with nearly 100 per cent efficiency, to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial electrolyser,” said Professor Qiao.

A typical non-precious catalyst is cobalt oxide with chromium oxide on its surface.

“We used seawater as a feedstock without the need for any pre-treatment processes like reverse osmosis desolation, purification, or alkalisation,” said Associate Professor Zheng.

“The performance of a commercial electrolyser with our catalysts running in seawater is close to the performance of platinum/iridium catalysts running in a feedstock of highly purified deionised water.

Mind you cobalt is in short supply but the idea of a catalyst is it is not consumed by the process.

An interesting process even given the scaling problem, coz there's an awful lot of ocean out there.

Feel the uni PR team have rather overplayed the Green tag there though.

the good side of it is that s we use up tons of water, it may help fight or delay the rise of sea levels

why? Green hydrogen is the perfect fuel.

It is. But proof of concept research is not an account of a sustainable and scaleable Green process.

You do this every time someone applies a critical eye to your future-centric utopianism. Get over yourself. I acknowledged the abundance of a key resource, sea water, but scaling has to account for all aspects of implementation and a closed or self-sustaining cycle has to account for all inputs and outputs - including construction, running, distribution, and decommissioning resourcing and costs. There's no account of how carbon or energy intensive this source of hydrogen might be, because that's not within the scope of the paper, so applying the Green tag seems more hype or hyperbole than accurately descriptive. Of course, the elephant in the room is the cobalt, it's abundance, performance and durability.

blather
there is lots of cobalt, I used to refine it at international nickel
The largest cobalt reserves in the world by country - NS Energyhttps://www.nsenergybusiness.com › features › largest-c...
7 June 2021 — According to the US Geological Survey (USGS), total cobalt reserves worldwide stand at an estimated 7.1 million tonnes, with 140,000 tonnes ..
Ramping up new supplies takes time but in the article it's a catalyst...do you not understand catalysts are not consumed? :banghead:

This is NOT new technology ....does the concept of green hydrogen elude you.

It's a better way to get it industrial level of green hydrogen by eliminating the need for pure water AND not using precious metals for a catalyst
Simple point you spin up into some faiery thesis with no basis.

Argue the article not your over complicated imagination. If that's what you call a critical eye ...heaven help the planet. :coffee:
