I guess we can now look forward to a new wave of scams promising to break the laws of thermodynamics to get free energy from water.

I, for one, cannot wait to purchase dehydrated water.

It's great for backpacking as it weighs much less and takes up less space in your pack. All you have to do is add water, shake it up, and your drink is ready in less than 15 seconds. Maybe the astronauts can take advantage too.

Couple of quotes from the OP:

"To produce hydrogen, water (H2O) can be converted into hydrogen gas (H2) by means of a series of chemical processes. However, as water molecules are very stable, splitting them into hydrogen and oxygen presents a big challenge to chemists. For it to succeed at all, the water first has to be activated using a catalyst – then it reacts more easily. A team of researchers led by Prof. Armido Studer at the Institute of Organic Chemistry at Münster University has developed a photocatalytic process in which water, under mild reaction conditions, is activated through triaryl phosphines and not, as in most other processes, through transition metal complexes."

Also:

"Dr. Jingjing Zhang, who carried out the experimental work, adds: “The hydrogen atoms of the activated water can be transferred to alkenes and arenes under very mild conditions, in so-called hydrogenation reactions.” Hydrogenation reactions are enormously important in pharmaceutical research, in the agrochemical industry and in materials sciences."

Suggesting applications might relate more to hidden enrichment than hydrogen gas production per se?

you laugh but i've always thought it would be great to carry a kilo of pure hydrogen in my backpack - just burn it to obtain like 5 litres of water ... I mean why are we carrying all that oxygen in our backpacks when he atmosphere has a plentiful supply of it...

Has been available for a while. E.g. https://www.rei.com/product/109906/aquatabs-water-purificati...

How much of a progress is this? Anyone here that can add insights?

The paper isn't about splitting water to yield hydrogen and oxygen gas which would be useful for energy applications. It's about a new way to make radical hydrogen (1 protein plus 1 electron) which is useful for synthesizing some organic compounds. It will be helpful for synthetic chemists and will make it easier to explore hydrogen radical chemistry. It may replace some processes that currently require transition metal catalysts, especially Samarium which is a rare earth element.
