As hydrogen fuel cell technology continue to improve, one idea is to fly hydrogen fuel powered aircraft. RR is looking into it. You'd imagine China's aeroengine manufacturers have to be looking into it also.
China's fossil fuel consumption continue to trend down and import continues to trend down. I read a few days ago that China is thinking of importing Australia again because it has to. Looks like it's doing a great job of meeting its domestic need with domestic production + shift to clean energy. Any additional imports would be to prevent surge period.

China startup makes large, flexible solar panels in industry first

TOKYO -- A Chinese startup this month became the first in the world to mass-produce large, bendable perovskite solar panels, based on technology initially developed by researchers in Japan.
DaZheng (Jiangsu) Micro-Nano Technologies invested 80 million yuan ($11.8 million) to build a production line with an annual capacity of 10 megawatts in Jiangsu Province. The 40 cm by 60 cm panels will be cut into smaller pieces and shipped to smartphone and tablet makers in China.
DaZheng will invest 200 million yuan in 2023 to expand its annual production capacity to 100 MW, Chief Technology Officer Li Xin told Nikkei.
Perovskite solar cells were pioneered in 2009 by Toin University of Yokohama engineering professor Tsutomu Miyasaka and his team. Although these lightweight cells have a power conversion efficiency of around 10% -- about half that of silicon cells -- they can be incorporated into windows, walls and more.
Smaller perovskite cells have been mass-produced before, but DaZheng is the first to do so for large panels. While these cells currently cost three times as much to make as conventional silicon cells, this could potentially be brought down to half at a higher scale.

A lot more installed solar/wind power in H1
The increase here is a lot more than the power generation increase. This tells me that some of the solar roof generation is not counted toward the overall total. It also tells me that a lot of the new capacities have not being connected to the grid or have been ramped up yet.
Further progress on the new CAP1000 plants at Haiyang
That means the 5th CAP1000 construction has started.
These are the cool parts. makes sense to use the extract heat from the energy generation process to heat homes.
Keep in mind that Romania canceled 2 power plants deal with China back 2 years ago after a conservative gov't came into power and is now talking about building SMR designs from American firm Nuscale.
Here is how crazy this is
Keep in mind that Westinghouse participation in nuclear plants at Georgia and South Carolina went so badly, that it went bankrupt in 2017. To me, it seems a terrible idea for any country that hasn't build nuclear plant for a long time to get involved in designs that the home country hasn't even finished. At least the Linglong-1 reactor has started construction. .

This firm doesn't anticipate completing its first commercial SMR until 2029 and Romania gov't somehow thinks this is their solution.

Dongfeng is coming out with a new 16 MW offshore turbine that could eventually support 18 MW. Possibly one upping Mingyang here
Record amount of solar installation in H1 with 31 GW, could reach 75 to 90 GW this year!
a large 800 MWh Vanadium flow battery is under construction in Dalian. 400 MWh in first phase and 800 MWh after 2 phases.
Seems like one of those things where they invest in every form of future technology and see what sticks.
oh yes, battery recycling. That will be important given the Lithium mining shortage and high prices.

Wow, I've been trying to find news on the Vanadium redox battery at Dalian for a while now. I haven't been able to find anything since it started construction a few years ago, and boom, now it's done!
Reading about it then it seemed like a really promising technology. Relatively cheap (when mature), almost infinitely scalable, and almost zero degradation. It seemed like a perfect utility scale electricity storage device. The only concern then was power output, but if it can indeed achieve 100MW for a 400MWh device then I think that's basically on par with Li ion solutions currently. IIRC the Tesla batteries in Australia also discharges in 4 hours.
Anyone more familiar with the technology can enlighten me on why it's not a more hyped solution for the intermittently of solar and wind?
Highlights how spot pricing is so important. People naturally tend to focus more at the supply side, but more often than not, its the demand side that can accelerate the change to renewables
