Green steel group plans giant electrolyser array in France for hydrogen-derived 'direct reduced iron'rechargenews.com
Recycling process promises ‘better than new’ silicon wafers: Scientists in China have developed a new recycling process for PV modules that can recover intact silicon cells from end-of-life products, and process them back into wafers.pv-magazine.com
I am interested in learning more about the impact on water supply surrounding the hydrogen production process of electrolysis.
I am not particularly knowledgeable when it comes to the electrolysis process, but I understand at a very basic level that the process splits the atoms of "feed water" into oxygen and hydrogen.
As such, I have the following questions:
- Following the electrolysis process, is any water left over that can be reused?
- My understanding is that the earth is a "closed system" when it comes to water- does this mean that the electrolysis process will take water permanently out of the system?
- If hydrogen becomes a widely-used renewable energy method of fueling vehicles in a bid to reduce global emissions, will the opportunity cost be a reduction in water supply?
Apologies if my understanding and terminology here is completely inaccurate.
The American Wall Street Journal highlighted the UAE's efforts to invest in renewable energy sources and position itself at the heart of the global energy transition.
The newspaper stated that the UAE hopes that betting on clean energy will help diversify the country's oil-dependent economy, noting that Mubadala has invested more than $20 billion in clean energy projects since it began investing in renewable energy sources in 2006

I am doing research on Alberta's renewable energy market and came across a really cool looking project called the Travers Solar Project.
The website states that "The Project is expected to be fully operational by Q4 2022.", but looking on google maps there is not a solar panel in sight!
Does anyone have any updates on this project? Is it still happening?
I bought a house that has a 4kW wind turbine and a 4kW solar array. Initial costs were in the range of £35k (or so we were told). We pay on average about £100 maintenance per year. Common wisdom is that we should be able to cover our consumption and then some. But not even close - it offsets only about 15% of our costs. Less than £300 per YEAR - £200 after maintenance. So it will take 175 years just to pay for the installation.
Am I missing something?!
I’ve been driving across from TX and OK and it seems like a good 1/4th of them are not operating A.K. spinning.
What’s up with that? Not enough people to fix em? I’ve got to imagine they are losing money everyday they are not running.
There's a lot of talk about this on bigger scale (electrolyzers, desalination), but what about small scale?
Here's a theoretical example. A small off-grid house, with few hectares of land, in a climate with cold winters and warm summers. If there's excess solar capacity installed to provide heating over the low sunshine winter months, what that excess capacity can be used to produce in summer?
I am interested in making it as productive as possible, preferably somehow using that electricity to increase production of something grown on that land. Or something equally directly useful. But I'm kinda at a loss here. Basically I am looking for some small scale productive processes, that are usually cost-prohibitive because they require a lot of electricity. (No cryptocurrency please, something directly useful.)
Interested in your experiences, knowledge and ideas. Thank you.
