- How to make use of hydrogen as an innovative energy solution for a sustainable future?
In his TEDx-talk, he gives us an overview of the functionality and prospects of hydrogen-based energy storage. He shows us glimpses of a hydrogen economy, how hydrogen can be used as fuel in automobile transportation and how it can be incorporated into our everyday lives as an alternative to fossil fuels. Tomas is a professor in Solid State Physics at the Department of Engineering Sciences at Uppsala University. His ongoing work undertakes research on low dimensional materials for solar cells, water purification, and solar fuels. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
A short introduction to hydrogen as an energy carrier, history of water splitting, and the untapped potential of solar energy to produce a solar fuel. The talk is intended for laymen and the younger generation.
For technical details and research related questions on solar driven water splitting and processes occuring on the surface of the catalysts, see our research at e.g. "Sustainable solar hydrogen production: from photoelectrochemical cells to PV-electrolyzers and
back again", Energy Environ. Sci., 2014, 7, 2056, "Direct observation of active catalyst surface phases ...", Energy Environ. Sci., 2019, 12, 572, or general comments on possibilities and challenges in uttilizing concentrated solar energy, "Water splitting: A concentrated effort" Nature Energy 2019. 4, 354-355.
A game changer is the new Plasma Technology developed by the Keshe Foundation, they have released a Stand Alone Plasma Generator with no moving parts to the Governments of the world which can produce Mega Watts of energy, this was initially developed for space travel and is now being used in Agriculture and Health, Mehran Keshe is a Nuclear Plasma scientist who has gifted this technology to the world, so no more fossil fuels or nuclear energy needed.
Amazing talk Tomas...explained very well.. I am using/sharing your talk weblink (will be running it online) for a conference back in India and Brazil. Will share details with you.
There are 3 problems with hydrogen, he only mentioned one. 1. It takes a lot of energy to separate hydrogen from water or methane. 2. Fuel cells are only 65% efficient. 3. Transporting and storing and compressing takes a lot of energy. End to end hydrogen is very inefficient. You are lucky to get back 50% of the energy it took to separate it, transport and store it, and use it in a fuel cell. That being said it may be the only solution for aviation, or shipping.
looking forward on how to discuss further
@@AIMGlobalEClVirgilioBAberte 90% of H2 sold in the US is derived from fossil fuel, and a lot of CO2 is released in the process. It's super inefficient, compared to just charging a battery. Still believe it has a place, just not in cars or light trucks.
@@carljaekle wishes to introduce ours. Thanks.
@@carljaekle You are 3 problems
Thank you for sharing your knowledge, Carl, hope more research and more efficient methods will be devloped
Sunlight is basically hydrogen light. All visible light can be thought of as derived from hydrogen energy transitions.
Oh! The Keshe Foundation have released a Hydrogen producing unit as well.
Its cool japan made cool cars
the fossyle fuels crisis on Erf..when will it be solved??!!
despite my silly comment (in the spirit of comedy based on making fun of accents and mispronunciation, which I enjoy while also being a non native english speaker with accent and miscpronunciation still being my thing), I thoroughly enjoyed the talk..thank you!
I find hydorgen exciting and I wish I could work in that 'movement'
I just lost interest in this one.
Then you just have a lack of brain cells mate
This is one of the worst explanations on the advantages of hydrogen and its potential to solve many of today problems better than any other solution.
If this person can make a TED talk, then I should be able to make 10 of this.
You know nothing. I hope you go to sleep thinking of that.
@@Topelbeats everyone who think I dont know what I am talking about, they get completely destroyed by logic, evidence and facts when I start to exchange knowledge with them.
So I am 100% sure that I know the hydrogen topic way better than this guy.
I knew the potential for hydrogen way before countries and companies started to invest a lot on it, because there is no other better solution in its range of application, I know all energy technologies very well, I know the best case application for each one, but in order to deliver or store clean power for longer than 5 hours (natural gas grid, trucks, airplanes, trains, ships, season disparities, etc), there is no other technology that can solve the intermittency of solar and wind solving at the same time co2 emission in all the sectors I mentioned.
Of course, batteries and other technologies also had their place of application, but not for the cases I mentioned.
Hey remember me? You are still wrong.
China made thorium reactor u can too
