Spliting of water, capturing of CO2, development of fuell sells are technologies that are prognosticated as very important steps in future energy conversion
Solar energy can be utilized by PV or CSP module and this source of power will become really cost effective only after considering the technical design,environmental, financial, management, architectural view factors such as: PN material,
Alloy of material working as bed,

Wind and PV are 2 of the principal upcoming primary production systems for renewable energy. For them to succeed, you need new, durable, economical electrical energy storage technology (batteries?) as iwnd and PV enablers.

The big break-through will be the recycling of CO2 into fuel. Another issue is the direct conversion of reductors into electricity by fuel cells. I'm working on utilization of hydrogen sulfide for electricity.
CH4 from landfills. Solar thermal. Geothermal. The cost and exergy have to be right for the whole system.
Along with large production of electrical energy through novel technologies, also make direct applicable renewables such as PV, CSP, WIND and make public to use the same in their day today.
Sure, you can change CO2 into fuel. But you need a lot of really cheap electricity to do it. Better to just charge up a battery and use that in your vehicle.
It is right, that first we must fabricate electrisity. But next problem is energy storage (at renevable energy technologi this is very important) Due to difficulties in accomulating bateries conversion of electricity to H2 or Metanol is a practical step to storing and transport energy prodused by cheap renewable energy sources. Hidrolys as next separated step of spliting water or metanol production looks not better than direct thermo-chemical conversion(few step process to lower operational temperature).
Next step is use of prodused fuel (H2 or Metanol). There is possible to use conventional transport vehicles or hybrid cars or cars withh fuel cells (as well as the stacionar fuel cells, produsing electricity). For fuell cell design are spent less resources, than for design of rechargeable bateries as Li-ion or other advanced kinds and can be espected more quick progress-newertheless that a delay exist!!
Hydrogen is the future fuel. As of now splitting water into hydrogen and oxygen is not a feasible approach but further research along this field can surely give us a solution.
As of now producing hydrogen from methanol is the most efficient method, there might be problem with respect to storing the fuel. This problem can be overcome by having integrated fuel processing systems. We can use microreactor for fuel reforming which occupies less space and is efficient.
Sabori Engine "Gas Plasma Exchange System" wow!!!!!!!.

I am more concern about reduction of CO2 to CH4 we should know Thermodynamics of system It have following stages
1.Conversion of two double bonds to single bond it will require external energy
2.Converted 'C' will be much valuable than fuel because at this stage we can convert it in to diamond also
3. Regular reduction with Hydrogen
We have to study molecular orbits and their energies and can do it but at very fundamental level.
Regardless of ratings, the Papp/Rohner/Sabori contraption was never demonstrated to produce any net energy. Neither is the imaginary possibility that it could do so backed by any meaningful theory: good view about PRS
Could any body give an opinion on wind electrisity production plus hydrolysis of water for production of hydrogen?
No idea though we are able to produce wind energy to electricity at commercial scale nobody ever thought of commercial production of hydrogen by electrolysis of water
Dear Vinayak! For example if you are on island of see or far from electrisity net, as well due to stohastic generation of wind electricity and need to store energy you can need to convert it in Hydrogen!
Joachim, Thank you for examples. Is in Germany stored methane fabricated by wind electricity?
Currently there is a demonstration facility here in Stuttgart. This facility makes use of more or less energy rich material (such as wastes) and converts it into hydrogen. However, the respective developers prefer the additional conversion of the hydrogen into methane as they argue that the respective infrastructures (at least in Germany) for methane are better developed and more mature. see: http://www.zsw-bw.de/infoportal/presseinformationen/presse-detail/weltweit-groesste-power-to-gas-anlage-zur-methan-erzeugung-geht-in-betrieb.html
Georg, Thanks for kind ansver. Your information is interesting for me! I suppose that it will of use and for other RG users!
Thank you Joachim for the data in your exellent answer! There one can learn interesting data on renewable energy sources.
As per my knowledge we require energy input to split water molecule in to hydrogen and oxygen if we oxidize hydrogen it will produce heat and with help of steam turbine we can convert it in to electricity bur my basic question is that is there any technology to produce hydrogen from water by splinting water molecule
About me Hydrogen might be the optimum as fuel, clean, no pollution, but on the other side difficult (if not impossible) to store, dangerous, explosive. Methane as gas on my opinion is the best choice as it burns well and is more easy to manage. Besides the Methane distribution network is already existing and its technology is up to date. Hydrogen technology is still experimental and has to come.
Regarding the water splitting the most known cycle is the sulfur iodine where sulphuric acid is decomposed to sulfur dioxide, water and oxigen; water and sulfur dioxide react with iodine in a second step to form Hydrogen iodide and sulfuric acid that recycles; Hydrogen iodide is then broken to hydrogen and iodine to reform Iodine and close the cycle. The total result of the cycle is the conversion of water in O2 and H2.
There are many technical problems to overcome before make this technology available for hydrogen production. The main developments are in Japan.
There is no doubt that hydrogen is good fuel and available technology is able to handle problems associated it but my doubt is that Is it technically and economically feasible to produce hydrogen from water ?
To produce Hydrogen from water is technically feasible of course as it is produced in some cases by electrolysis; but from economical point of view other fuels are less expensive and give less problems (i.e. methane)
Fossil fuels ar nowaday more effective and less expensive, but they are limited and their prices are increasing rapifly. So production of H2 and carbon-hydrogenates(taking CO2 from atmosphere or directly of sources of its generation(combustion of fossil fuels) will become more and more economically and ecologically usable!
Well, it depends. In Germany energy production from solar cells and wind has become a certain problem. The wind plants are often in the Northern Sea while storage capabilities are extremely limited in this area. This is why people have started thinking on energy storage systems e.g. based on hydrogen that may has its origin in electrolysis.
It is really good to hear from Georg Herdrich. We are working on "how to avoid the bird hitting problem at the WIND TURBINE BLADES".
