Soaring European wholesale gas prices are encouraging more utilities to switch to carbon-heavy coal to generate electricity just as the region tries to wean nations off the polluting fuel. Although European coal and carbon prices have also jumped in recent months, they have lagged the spike in gas prices, causing short-term marginal costs to shift in favour of using coal to generate electricity. Benchmark carbon permit prices under the European Union’s Emissions Trading System (ETS) have almost doubled since the start of the year while European coal futures are more than twice as high. Wholesale Dutch gas prices, however, are almost four times higher than at the start of 2021. Ahead of the next round of United Nations climate talks in Scotland in November, the EU has been encouraging other big polluters to commit to more ambitious climate targets and move away from coal-fired power.
As your Hellenic link talks about, it's minor changes in the pricing of various alternatives that drives the shift to alternatives, so economics do matter. Whether it's too costly at present or not remains to be seen, and depends partly on further flucutations in costs of alternatives. But fossil fuels are limited and thus prices have to go up eventually (or continue to rise), and as they go up the greener alternatives will become economically more viable.

One way of doing so is replacing the Coal with Hydrogen Plants to generate electricity. Too costly? Bull sheep! It can be done and it is quite green.
That's nice to see, I hope they are very successful. It sounds like they plan on producing more ammonia as a means of shipping the hydrogen to global markets. This also requires economical ways of getting the hydrogen back out of the ammonia. This article says ammonia can be burned in internal combustion engines, though it seems like those engines are still in development:
My former company Air Products & Chemicals is building a Hydrogen Plant in Saudi Arabia.
The key point seems to be that changing prices of alternatives can shift demand to the less expensive alternatives. This will continue to be an issue as long as the greener alternatives have marginal economics, but, someday the economics of greener alternatives will work out, as fossil fuel prices go up more and more.
Here's the Hellenic Link:
Switch to Coal
But fossil fuels are limited and thus prices have to go up eventually (or continue to rise), and as they go up the greener alternatives will become economically more viable.
Representatives from nearly 200 countries will meet in Glasgow, Scotland, from Oct. 31-Nov. 12 for climate talks to strengthen action to tackle global warming under the 2015 Paris Agreement.
A U.N. analysis of new or revised NDCs submitted by the end of July found that by 2030, those 113 countries would together lower their emissions by 12% from 2010 levels.
But the available NDCs of all 191 parties of the Paris Agreement combined equate to a 16% increase in greenhouse gas emissions in 2030 compared to 2010, it said.

Hydrogen? LOL
One Word…. Hindenburg 😆😆😆
There are two questions we can ask:

This is probably the thing I've ever disagreed with you on here, what studies show they are limited?
We constantly find new reservoirs with expansive natural and crude resources, and the current ones being pumped are not running dry. Peak oil is not real.
...whilst many worry about the possibility of fossil fuels running out, it is instead expected that we will have to leave between 65 to 80 percent of current known reserves untouched if we are to stand a chance of keeping average global temperature rise below our two-degrees global target.
