This is very promising tech. Idk why people say hydrogen is a useless energy. It may take more energy to make it than it is stored but that is the way every energy medium is. Even fossil fuels that are already exisisting take more energy to extract/refine than they give back. Same thing with batteries.
Also by making the hydrogen with solar it is minimal cost especially considering the time the solar panels will keep producing for tens of years assuming no physical damage from external force. As someone already mention the have solid state bydrogen storage where the hydrogen is stored or attached to metal. No high psi or combustability required so it is very stable.
The solar efficiency record in real world use is 33% while the record in a lab is 43% achieved by G.E. Per yard of the earth at the best time and lattitudes recieve 1 kw per sec. Germany produced the same amount of solar power as the U.S. did with nuclear power in 2011 percentage wise which is about 20 %. Obviously 20% in America is more than 20% percent is in Germany. The point being is it proves how viable it is and the fact that Germany recieves less sunlight than London or Seattle. Why do some people some blame solar on not being efficient enough when every technology we use is extremely inefficient. If you go by that logic than the car or computer would have never been created.
It's also economical but its not being mass produced and when compared to exsisting tech that is mass produced and is also subsidised only then is it more expensive. All this was only talking about solar. With all other alternative/sustainable non-polluting sources like wind, geo-thermal, wave, pizeo, any thermal, its amazing and disturbing we are not moving away from fossil fuels more rapidly.
This is all true and is not coming from any bias. I love that fossil fuels provided as much as they have for this country and we would not be here if it were not for them But it is obvious that it has reached a time when it is time to switch from a economic, environment and security standpoint. I feel for the people that would lose jobs but if as a country/world we set a date 5 years or so in advance that would be plenty of time for the change. Companies making money will never make the switch until it more profitable for them which would be a very long time b/c they want to milk the fossil fuel market until it is exhausted.
As for global warming or more appropriately climate change there is no denying that in the past the Earth has gone through wild swings in temp and climate. The huge difference now is the pace of the change. Any warming or ice age happened very slowly i.e. tens of thousands to hundreds of thousands of years whereas man-made is happening much more rapidly to the extent that plant and animal life will be extremely more likely to fall victim to those changes and obviously affect human life. To help put in perspective the sun has solar flares that are billions of tons and are ranging from 1/5 to the size of the son itself. The son is a million times bigger than the earth son when we release billions of tons of a greenhouse gas every year for many decades plus all other years it is obvious that would have to affect the Earth.
I am in no ways trying to make anyone mad but if you look at climate change objectively and critically think about it, it becomes apparent how simple a problem it is. If you do not believe in it there is no point in arguing b/c it is true and assuming climate change is wrong we need to get off fossil fuels for economic, security and other environmental reasons.
Again lets not start a pointless arguement and derailment of this thread. We only need solutions and those solutions are upon us. I am not some hippie and anyone who uses that term does so in a negative way only b/c the stigma exsists, while also not contributing to the solution in any way. Also for anyone who believes in God they should want to take care of the Earth.
Thanks for reading and I hope this only inspired people while promoting critical thinking without bickering and pointless argueing.
