Toyota and VDL have jointly integrated Toyota's fuel cell technology into further heavy-duty trucks. Following the successful deployment of an initial demonstration vehicle, four more trucks are now being tested in daily logistics operations on international routes.

 

Collaboration with ZeroAvia will study the ‘potential adoption’ of hydrogen for its fleet of turboprop twins, including the Twin Otter.

 

Japanese researchers at the RIKEN Institute have developed a groundbreaking manganese-based catalyst that significantly enhances hydrogen production, paving the way for a more affordable and sustainable green hydrogen future.

 

Catalysts and precatalysts are key components in the electrochemical water-splitting reaction that produces clean hydrogen fuel.

 

Hydrogen fuel cell trucks from VDL Groep are moving parts from the Toyota's parts centre to France, Germany and the Netherlands.

 

Rocks in some parts of the UK have the potential to produce natural hydrogen, but it remains unclear whether the gas is present in economically viable quantities

 

Leh: In a historic step toward green mobility, the Union Territory of Ladakh witnessed the official launch of India’s first-ever hydrogen fuel cell bus service at the world’s highest altitude.

At a formal ceremony held at the NTPC Green Hydrogen Mobility Station in Leh’s Palam area, five hydrogen-powered buses were handed over by NTPC Limited to the State Industrial Development Corporation (SIDCO), UT Ladakh.

 

Airbus and MTU Aero Engines have signed a strategic Memorandum of Understanding (MoU) at the Paris Air Show to advance hydrogen fuel cell propulsion technology for commercial aircraft, marking a major step toward zero-emission aviation.

 

A natural gas-fired plant outside Atlanta has completed what is described as the largest 50% hydrogen-gas blending test of its kind.

 

Researchers at China's Tianjin University have achieved a milestone in solar-powered hydrogen production, developing a semi-transparent photoanode that pushes solar-to-hydrogen (STH) conversion efficiency to a record 5.1 percent.

Breakthrough innovation is happening in fuel cell technology outside of traditional sectors like cars. BEVs are weirdly turning into a legacy business, and the car industry is becoming an innovation laggard. As of now, it seems likely that hydrogen fuel cell technology will be revolutionary in surprise sectors, such as forklifts, drones, VTOLs, ships, etc., bypassing cars.

It also means that existing car manufacturers are becoming increasingly out of date with their understanding of the technology. We could have millions of hydrogen fuel cell vehicles running (or flying) around before many car manufacturers build their first ones.

Hydrogen exists naturally in the environment. These are silly claims likely originating from the fossil fuel industry.

Most of their games come out on PC now. We are not far off from some SteamOS based PC that works like a console. Sony would be crazy to think they can charge the same price.

The problem is that at those prices, a PC is a more logical purchase. PS6 will have to be priced similar to PS5, or it will underperform dramatically.

Using hydrogen as a bulk energy carrier will enable the hydrogen infrastructure. Unlike wires, you do not have to physically link it to every home. You can have last-mile solutions like using trucks. You also only need to convert existing fuel stations. So the scale is much lower, and likely much cheaper too.

Hydrogen cars are proving to be safer than gasoline cars. The fuel is lighter than air, so it does not linger like gasoline does. There are no known serious car fires in FCEVs. Even li-ion batteries have the same problem of gasoline, namely that the energy source of the fire stays in place. As a result, many people have died or been injured.

You don't technically need one. You can make hydrogen locally if you had too.

Also, a hydrogen infrastructure would be cheaper than a comparable electrical infrastructure. People have forgotten or never realized how complex the grid really is.

This sounds like more magic batteries from the future rhetoric. An endless loop of fantasy ideas that never materializes into something usable. Right off the bat, you suspect it will be expensive to be viable for BEVs: https://www.goldenstatemint.com/blog/samsungs-silver-solid-state-battery-technology-1-kilogram-of-silver-per-car/

Note that you can build an entire energy storage system using hydrogen. People are simply refusing to accept that this is effectively a type of battery. People have a misplaced loyalty to existing technology, even though they would've laughed at its limitations just 15 years ago.

You are imagining BEVs with ever larger and ever less cost effective batteries.

The problem is that the BEV was never intended to replace all cars. To even push this idea just means extremely expensive and non-environmental friendly batteries. You are just wasting your time on pushing greenwashing.

In reality, hydrogen is the only possible solution for most of transportation. Electricity should be reserved for directly electrified vehicles like trains or trolleybuses. Batteries powered vehicles only happened due to massive subsidies. It will revert back into a tiny niche or disappear entirely once those subsidies go away.

[–] Hypx@fedia.io 1 points 10 months ago (2 children)

That's just an indirect way of power a car via hydrogen. Sure, it can work. But it just implies that having cars directly powered by hydrogen are the better idea.

Because a fuel cell is type of electrochemical device. It is literally a type of battery. So whether you are using a li-ion battery or a fuel cell, you are turning chemical energy into electrical energy. Also, the process of distributing hydrogen is comparable to the grid and has similar losses. The latter of which will see a dramatic reduction in efficiency as more renewable energy go onto the grid. Specifically due to the need for energy storage.

There are no experts saying hydrogen for cars is stupid. You are just hearing a lot of pro-BEV marketing and their fanboys. Of course, some of them pretend to be experts, but they are not.

In the long run, BEVs are going to die off because they are not economical vehicles. They cost far more than conventional cars and require huge amounts of new minerals for the raw materials used to make them. If the goal is just to have an EV, then the answer is a type of EV that does not so much raw material nor cost so much. That leads to ideas like PHEVs or FCEVs.

You are not reading my post. The entire set of steps is exactly the same number of steps as charging a battery. Both are electrochemical processes and have similar losses. In theory, we can make a fuel cell that operates just as efficient as a li-ion battery.

The other point is that the process of moving hydrogen around is cheaper than moving energy via electricity. Losses of distribution are similar too. People are forgetting how big and complex the grid is.

Which is about the upper limit of a reasonable powerline. I'm pretty sure they had to resort to HVDC to get it that long. Note that I did not say it was impossible, only impractical. You lose a lot of energy when it gets very long.

I also know that Quebec is making hydrogen with their hydropower. Clearly, they know something you don't.

Pipelines go for thousands of km too, and send far more energy with smaller losses than wires. This is due to physics: A pipe is a hollow tube and scales up better the larger the diameter of the tube. Wires do not scale up as well.

A battery car does not "skip the middle part." It relies on a huge and resource intensive battery to store energy. This is electrochemical energy storage, and works the same way as how a hydrogen car stores energy. As a result, there is no fundamental advantage to using a battery. As costs comes down and as fuel cell technology advances, it is likely that there will be zero or next to zero efficiency advantage for the battery car.
