Rather than efficiency, I saw something about regulations, which can force the plants to have various installations to reduce emissions.
And for this, China was far ahead than say Australia.
Let me try and find the article.
Edit: Found something else
But basically, the newer installations and stuff on plants are helping to reduce their emissions (I suppose they might be put on older plants, maybe?).
Anyways, the newer plants are still greater/better than the older ones and might also have more 'functions' (such as being able to scale up energy production quicker?).
It won't be be expensive when renewables and nuclear power generation facilities come to overwhelmingly dominate the power generation grid. The much reduced cost will offset the storage drawbacks and fuel cells, just like anything else will be much more affordable than presently to produce.
The great domination of renewables and nuclear power generation because of their combined extreme efficiency and abundance ensures that their energy outputs are much greater per unit than anything that fossil fuel generation facilities can provide and they will because of that usher in a prolonged era of much reduce material abundance globally. It is not a question of technological and financial wherewithal. The technologies and financial capability exist for a transition globally in 40 to 50 years. It is a matter of political will. China, which isn't overcome by the myriad of inimical special interests and whose much more meritorious political system than adversarial multi party democracy does possess the political will to make that transition and can influence others to do so and can actually bestow such beneficial goods to those states that do not presently have the wherewithal to do so...
Nickel-Hydrogen
It is a known technology for spacecraft, but it was very expensive, this is a good way: to cheapen known technologies. The list of storage systems is growing every day. For now there is no pressure on the Market beyond stabilizing the Grid and storing 2-4 hours. But as more renewables are installed, the need for storage will increase.
In the future (2030/40-) we can imagine a Grid that would be for example (?): 40% Solar, 20% Wind, 10% Water, 20% Gas, 10% Nuclear.

A long rebuttal to a BS article from the "Foreign Policy" about China's coal-power industry, you will see that China needs a lot of energy in the future, a sure sign that its economy will keep developing in at a relatively high tempo:
China now considers climate change has become a "major risk" in China's modernisation
that's great.
Saw this tweet from Zhao Lijian's account
reforestation is one of the more important part of China's fight against climate change and soil erosion and desert storms and a whole host of things. I remember back 15 years ago, Beijing used to have yearly sandstorms until they stopped the desert growth.
In Davos, they pledge more tree planting. It would be interesting to see how they do this. Having more biodiversity in reforestation would help their impact on the environment.
Unsurprisingly, their emissions are likely to come down again in Q2
that's great.

China aims to start work on 270GW of pumped storage facilities by 2025
The chairman of the Power Construction Corporation of China (Power China) has said the country plans to begin work on more than 200 pumped hydro plants with a combined generating capacity of 270GW by 2025.
According to the Bloomberg news agency, Ding Yanzhang told the People’s Daily newspaper that the schemes would generate more than all the power stations in Japan. They would also raise China’s installed capacity by around 10% and increase the world’s energy storage capacity by around 170%.
If these schemes go ahead, they will mark a striking increase in what was proposed in China’s five-year plan for 2021-25. There it was envisaged that 62GW of pumped hydro would enter service and work would begin on 60GW more.
In January, the State Grid Corporation of China switched on the world’s largest pumped-hydro station in Hebei Province, the 3.6GW Fengning facility.
In February, Power China held the first meeting of its “supply chain assurance working group”, formed to support the ramping up of pumped storage schemes. The company notes on its website that the aim is to ensure new pumped storage projects have “safe, reliable, strong and efficient supply chains”.
Power China is a state-owned company made up of 779 subsidiaries, including well known companies such as SinoHydro. It is presently the fifth largest contractor in the world.
Pumped storage is a way of storing energy in its potential form. The idea is to pair it with wind or solar plants, and use their excess generation to pump water from a lower into a higher reservoir, creating a “water battery”.
According to the International Hydropower Association, pumped storage accounted for 158GW of storage in 2019, or 94% of world energy storage capacity. Recent studies by the association suggest there are more than 600,000 non-river sites that can be exploited in the future.
China is also progressing plans to deploy newer forms of energy storage such as lithium-ion batteries, with the country’s largest grid saying it hopes to have 100GW of such capacity available by 2030.
