China breaks new record this:
Another little feat of China in the field of energy that will be talked about.
Chinese researchers have just broken a world record for solar-hydrogen conversion. Meanwhile, with so elegant technology that you almost want to say thank you in the sun. In addition, It is not “yet” a large complex device in platinum or rare land. Meanwhile, No. For example, this time it is a thin layer of copper, zinc, tin and sulfur, posed like a varnish, and which transforms light … For example, into fuel.

The material is called CZTS. Meanwhile, It is less poetic than “orchid”. Moreover, “firefly”, but in the field of solar energy, it is a name that we will remember. Furthermore, Because this small assembly of simple metals, copper, zinc, tin, sulfur, costs three china breaks new record this times nothing and needs no rare ingredient.
So far, the CZTS has never exceeded 8 % yield. For example, He did what he could, slowed down by microscopic defects, poorly ordered grains, electron losses. Moreover, And then there. Moreover, a simple and fine idea changed everything: preparing the material with a method called Precursor Seed Layer Engineering. Additionally, Moreover, We improve the starting layer, we grow the crystals in the right direction, and suddenly … the yield increases to 9.91 %. It is a world record for this technology and which should appeal many others.

Current, hydrogen … and salt water – China breaks new record this
The most beautiful? The team managed to run a CZTS – bivo tandem cell without any electrical voltage. Just with untreated solar light and sea water. No need for a sanitized laboratory, nor a purified acid bath. A simple salt water tank and a piece of blue sky is enough.
The fuel of tomorrow could come… from a solar film
This thin film (barely a few microns thick) could soon land on reservoir walls. sea buoys, floating modules. We immerse, we light up, and we harvest hydrogen. No pump, no compressor, no high voltage line. Just sun, water, and a tidy material.
It is a track for small coastal china breaks new record this villages, ports, islands, remote areas. A clean. silent, continuous source of energy, which does not depend on oil or natural gas and which rejects nothing other than oxygen.
A bridge between the laboratory and the shore
The researchers insist: the process is compatible with industrial production lines. It only uses abundant materials, can be applied by simple deposit, and does not require any precious catalyst.
Their cell reaches a current density of 29.44 mA/cm², to a hair of the theoretical maximum and above all, it remains stable. No brutal fall after a few hours. No visible degradation.
France “shines” in a sector of the future with the largest laser in the world with a power of 10 petawatts
Hydrogen. future industrial pillar despite its exorbitant price?
In France, the signal is already launched. The state provides 6.5 GW of electrolysis by 2030, with investments of several billion euros. The stakes are twofold: decaroner the difficult sectors (steel, cement, heavy transport) and create a new industrial fabric. Projections speak of more than 100,000 jobs. It is a long -term bet, but with possible benefits on all floors.
For this transition to take, it is not enough to have electrolysers. Transport networks, storage capacities, suitable ports, shared technical standards are also needed. Clearly, a whole ecosystem to build.
The price of green hydrogen is still high china breaks new record this today. generally located between 4 and 10 euros per kilogram, depending on the region and technologies. Despite a slightly expected slight decrease. Bloombergnef experts anticipate that its cost will not drop significantly until 2050 for an estimated price between 1.5 and 5 euros, which remains above the price of gray hydrogen from natural gas. However, some markets like China and India could reach parity in 2040, thanks to their massive investments in renewables.
