NOX isn't CO2...
We'll all be killed by cancer long before the CO2 induced global heating burns us all to death when the planets temperature rises to a hundred gazillion ballizion degrees.
"Well, yeah, you know, that's just, like, your opinion, man"

In reality, it will look quite like this image of Gunfleet sands wind farm in the UK. Those turbines are about 50% smaller, but also about 40% closer than Kish. So the difference to the casual observer will be minimal.
As a resident of the area also, I wouldn't be too disturbed by that view. Especially given the greater context.

The 9HA's are big power turbines , up to 571MW, that can be upgraded to 100% H2 in the future and have NOX reduction today.
The DLN 2.6e maintains many of the elements of GE’s DLN 2.6+ combustion system and introduces advanced premixing for reduced NOx emissions while enabling high plant efficiency. Its advanced premixer enables expanded fuel flexibility to operate on both “rich” and “lean” gaseous fuels, a 50% hydrogen (H2) capability with a technology pathway to 100%, a gas turbine turndown to 30% load, and an optional park mode at 7-15% load, further reducing customers’ operating costs.
If you need 80% hydrogen today (and we don't) you'd have to settle for the smaller 9F's at 288MW
a GE 6B gas turbine (~44 megawatts) that has operated for more than 20 years on a refinery waste gas with a hydrogen content that has varied from 70 percent to 95 percent (by volume). This isn't new tech.
You claim that £150/100MW is a non runner at grid scale but there will be economies in scale. More importantly Hinkley C increased in cost by £100/100MW in 2022 and also in 2019. Other cost increases at that one plant would pay for conversion of a gas field to storage. (or use the cost increases at Vogtle for a different supplier on a different continent)

Speaking of rain, MET Eireann released their 2022 climate report which showed rainfall was below typical levels at most stations. Lots of other interesting points to note
On rainfall
On temperature, above average everywhere, warmest year on record overall
On climate change they have this to say
Ireland’s warming trend continued in 2022, and we are warming in line with the global average. Other countries are warming at a greater rate than Ireland and the summer of 2022 saw multiple heatwaves and record-breaking temperatures across Europe and around the world. The spring and summer of 2022 were drier than average in Ireland, which had negative consequences for agriculture and wider society.
The latest Irish climate change projections indicate further warming in the future, drier summers on average and an increased chance of heatwaves and periods of drought. The Irish summer of 2022 is broadly consistent with projected future trends. While climate change projections also indicate a trend toward warmer winters, cold periods like those experienced this December cannot be ruled out in any particular year.
Keith Lambkin, the Head of Met Éireann’s Climate Services Division said: “Climate change has changed the odds of getting more frequent, more extreme heat related events. Thanks to over a century of dedicated weather observations here in Ireland, we know that 2022 brought us record-breaking extremes as well as what is likely to be the warmest year on Irish record. It is essential that we must continue to adapt to ensure our national infrastructures and planning are best suited to both current and future warming.”
Have you seen their monthly reports? Very interesting stuff. Take for example, December where rainfall was way down on the average as was temperature

UK strike price for offshore wind is £37.35/MWh and other technologies are in the same ballpark it so it's not an outlier. Average is £41/MWh
Offshore wind at £37.35/MWh is 40.4% of the Strike price for nuclear of £92.50/MWh. Electricity from stored hydrogen is within half a % of nuclear.
But you'd only use stored hydrogen for peaking , the rest of the time you'd be using wind or solar or (gas within 20% limit) which are way cheaper than nuclear.
The £150m/100MW is total project cost. So treat it as a maximum cost for early adaption.
What is this obsession with desalination ? The output of the generators (turbine or fuel cell) is pure water , which last time I heard was reusable. In Ireland water isn't that expensive and it literally falls from the sky so you could be able to harvest a tonne per m2 per year.
Again even in a desert mechanical vapour recompression reduces the thermal input needed to distil water by 99% and ultrafiltration is a thing.
Hydrogen molecules are easier to store than helium atoms. Almost all of our helium comes from gas wells where it's been stored for hundreds of millions of years.
For the Nth time many of our gas lines used to run on 50% hydrogen in city centres so it's been done. BTW only certain metals suffer embrittlement and it's not softer cheaper kinds like used in pipes. Pipes can also have linings installed.
The capex is for the investors to pay not the customer. (unless it's nuclear where the government has to offer additional financing guarantees)
The strike price is the contracted price of the electricity. (When you buy an airline ticket you care about the cost of the ticket, not who paid for the plane)
After 15 years it's whatever the market pays for renewables. Nuclear will still command over twice the price of renewables for 35 years.
