Hydrogen nearly there then .... the Ls700h maybe

[Las Palmas]

Some think everything is impossible. Some try to do what other think cannot be done.

Current price for a kilo green hydrogen is less than 5$. 33.6KWH. Unfortunately, only in India for now.

0.55 kg in a Mirai can take it 100 km or a bit less than 200km on 1 kilo (180). How long can your car drive for about 5$?

Reality out in the market is that the industry has chosen. Remember nobody insisted them to start producing electric vehicles, the demand was the dreaded co2 95 grams that will become lower over the years. The industrywide answer was electric vehicles and not hydro. If hydro is or would have been the wonderful solution as some on here seem to think why not the other way around?

There is no wonderful solution to the mess we and our forefathers have made.

We want our children to live in a decent world have a decent life and the way of just continue as always is not leading that direction.

Electric cars were chosen as that was the easy solution because there is an almost acceptable grid. That it is not at all sufficient to charge all cars we think we need and never will be for people living in cities does not help. Real bad is also all the batteries that will lose their capacity in a far too short time and are useless when temperature go low enough. It is very expensive and polluting to get just a little part of the material the batteries are made of back from.

Automakers are not in the world to make it a better place to live in. They are here to make money and that is what they plan to do. Unfortunately, that will leave us with so many used worthless batteries that it will be more difficult to get rid of than the atomic waste we are also very concerned about.

So then ..........  when can I place my order with Lexus for the ( to be ) new Lexus Ls700 hydrogen spec'd car  ?🤩

First Malcolm, do not listen to those telling things are impossible. Some are negative and will not believe, some even after thay have been proven wrong.

You will have to be a bit patient, as so far only Porsche has made a promising model in computer (that is the way new engines are made these days) of a V8 combustion engine more efficient than the ones they have running on gasoline. Or chose the Toyota engine refined and converted in company with Yamaha. When they will be available I know as much about as you do. But now the Mirai has a little tank that give a range of 1000km a bit more than 620 miles. No engine noise though. But do not listen to those saying it is impossible or other silly things.

Hydrogen has not been worked on for very long and the progress made in the short time the big money companies have shown interest mean that the 2030 with only EV engined cars will never happen. Toyota has made prototypes of functioning canisters that can be used to transport hydrogen to where is shall be used, without problems.

If we are willing to live in California there are now hydrogen tanks where cars can be filled. 5 minutes to fill a Mirai and the latest model has quite a range now. 1000km and even if not using the range in a month or more you will not lose one single kilometer like you would in a Battery car with the way batteries lose power when not being used.

Solar panel that splits water boosts hydrogen fuel production efficiency

 

New technology developed by University of Michigan researchers is 10x more efficient than previous tech.

University of Michigan researchers have developed a new solar panel they say is 10 times more efficient at splitting water into its hydrogen and oxygen components than previous artificial photosynthesis strategies.

The process uses a catalyst made from nanowires of indium gallium nitride formed on a silicon surface.

The indium gallium nitride nanowires are grown onto a silicon surface to make the catalyst. In this way, it provides the considerable advantage of being able to tolerate notably higher temperatures than previously developed systems. By being able to use higher temperatures, the solar panel’s process of splitting the hydrogen and oxygen from the water molecules occurs much faster, substantially boosting efficiency. Equally, it also inhibits the recombination of the H and O.

According to the researchers, the new design has achieved a 9 percent efficiency level for the conversion of water into its hydrogen and oxygen components. This type of artificial photosynthesis is considered to be one of the strategies for sustainable hydrogen that is most promising as a viable clean energy supply.

The design uses a large lens to focus light directly at the solar panel with an underwater semiconductor chip.

The research team used a lens about the size of a typical residential window. With it, they direct focused light onto a small panel that contains a semiconductor chip which is underwater.

“We reduced the size of the semiconductor by more than 100 times compared to some semiconductors only working at low light intensity,” explained University of Michigan electrical and computer engineering research fellow Peng Zhou, the study’s lead author.

By using a layer of insulation, the panel maintains a steady 75 Celsius degrees, which is a good temperature for efficient water splitting and for long-term use of the design’s semiconductor.

When the researchers tested the solar panel outside, where sunlight is less reliable and temperatures are variable, the hydrogen fuel production efficiency dropped to 6.1 percent. That said, within an indoor controlled indoor environment, it was a steady 9 percent efficient. The team is working on further efficiency improvements to produce high purity H2 that can be fed directly into fuel cells.

This is a very interesting video. It's contradictory to other videos on hydrogen. What do you think?

 

 

[dutchie01]

Interesting. Sounds like the explanation why car manufacturers went for BEV instead of Hydro.

[Malc1]

I think the inevitable " tie-up " between BP manufacturing hydrogen ( for it's UK wide fuel station estate ) for engines, in the north of England and Toyota with it's global scale and it's new truck engine hydrogen plans in the UK, will bring the Hydrogen concept into reality a lot faster than one could have ever imagined ......  notwithstanding the niceties of hydrogen specifics at this stage 

The debacle at Blyth with the proposed EV Battery plant needing £3.8bn to come into production has shown that whatever Govt might be in power in the UK it's now going to be the realities of unlimited financial prowess of the likes of BP and Toyota that will drive new age motoring ....  at least in the UK and near Europe

My thoughts anyway
