This sounds like it could revolutionize hydrogen electrolysis from water. Currently the electrolysis requires catalyst made of platinum which is rare and costly. “Graphene discovery could help generate hydrogen cheaply and sustainably.” ScienceDaily.

2023-08-19 Electric Vehicle Batteries – What Happens To Them
Electric car batteries and all other lithium batteries are processed into ‘black mass’ at this Li-Cycle facility in Gilbert AZ. 95% of the batteries is recycled into inert, mostly plastic waste, copper and other heavy metals, and black mass where the lithium, cobalt and other valuable minerals are. The process starts with shredding the batteries

2023-08-15 Methane+Sunlight+ Catalyst = Emissions Free Hydrogen – Research
This sounds like it could be developed into a very important process. Methane + sunlight + boron nitride catalyst. The end products are hydrogen and just carbon – not CO2. So the carbon never enters the atmosphere, never becomes a greenhouse gas. Methane + Sunlight + Catalyst = Emissions-Free Hydrogen, Say UCF Researchers

2023-07-04 The End Of Haber-Bosch – Its Replacement
New research has enabled fixating nitrogen easier than by the Haber-Bosch process. About half the world’s food supply depends on the fertilizer made by the Haber-Bosch process. It is imperative that we end the use of fossil fuels in the Haber-Bosch process because its end product is CO2 greenhouse gas. It must be replaced by

2023-06-24 Why Is Water So Remarkable? Tyson
Neil deGrasse Tyson explains why the remarkable change in water at 4 degrees C is why we are alive today. When water gets colder it gets denser, until it reaches 4 degrees C, then it gets less dense as it gets colder until it freezes at 0 degrees C. This causes the ice to float

This Cleantechnica article about research and development advancements on batteries using aluminum-ion and aluminum-sulfur chemistries. German Universities; Lyten company announcing opening a pilot battery factory for lithium-sulfur cells. Quote: “”Aluminium is the most abundant metal in the Earth’s crust and its recycling is easy. Its high volumetric capacity of 8040 mA-h/cm−3 as a negative electrode

2022-05-24 High Energy Battery Lasts For 100 Years
This research from Canadian Dalhousie U. and Jeff Dahn says they developed a high energy density battery that could last for 100 years. The energy density is better than LFP cells. The problem is that it requires cobalt, nickel. https://electrek.co/2022/05/24/tesla-battery-research-paper-high-energy-density-battery-last-100-years/

2022-05-06 Methane Is Much Worse Than CO2
The world has a much more dangerous greenhouse gas than CO2 – it’s methane, also known as natural gas. And huge amounts are locked up in the environment, and may be released by global warming. Biofuelspk said, “… natural gas which is 84 times worse for climate change compared to CO2.” I’ve read the numbers
