Fellow Researcher can you please suggest a relevant PhD research topic in Renewable/Sustainable energy Systems? I'll appreciate if you can help me identify a clear problem and an incline to the possible solutions.
Dear sir
Please consider the following topics
feasibility study of fuel cell, photocell, storage tank and electrolyzer by exergy-economic and advanced exergy analysis
Using ORC cycle by geothermal inlet energy for cooling the inlet air of gas turbine cycle
If you are eager in any branch in renewable energy subject, feel free to contact with me.
Sir, at Mohamed Azab can you give us more exposure around energy management system
Dear sir
It highly depends on your background. According to your major, I would recommend studying pv cell or electricity storage.
Renewable / Sustainable Energy is a very broad subject, you must first define according to your expertise if what you are interested in and what you know is biomass, wind, geothermal, solar, or which of these topics. Once you do this filter, you should start reading scientific articles on the subject.
If your interest is biomass, the search for new non-food sources to obtain bioethanol or biodiesel is the key.
No easy answer. If you are student really depend on your supervisor. I suggest you to read latest review paper on topic you are interested in. Some you can find here:

As we move toward 100% non fossil energy we create a new problem. Will renewable energy have enough energy from day to day to power the energy needs of that day and the next day and the next day? In Texas several days of cloudy nearly calm weather in February create an energy shortage problem that is surprisingly worse than meeting summer loads. You can see some of the hourly data in this file I have posted which has links to the data https://egpreston.com/storage.pdf What is needed is long term low loss low cost energy storage but it does not yet exist. Some nuclear energy can bridge the gaps in renewable energy shortages.
Abdelhalim abdelnaby Zekry made this remarks to a similar question i asked recently;
One important point to consider is the development or repairable modules to extend the life of the photo voltaic installations. An other point is the recycling the solar cells and the panels. Repair ability will help in recycling and renovation of the solar panels.
The other very important area of advancement is the power conditioning circuits and controller for the PV generators.
One can also mention the development of loads that can work directly with the PV generators.
Best wishes
Multijunction solar cells based on Si -HET top cell, c-Si Middle cell and epi-SiGe bottom cell. You can see one of our good paper , which can cover some part of future project. Please see one of our paper :
Growth and characterization of low composition Ge, x in epi-Si1−x Gex (x ≤ 10%) active layer for fabrication of hydrogenated bottom solar cell

One of the future potentials is to use solar energy for hydrogen production through biomass pyrolysis, as disscused in the below mentioned research. Happy new year.

You already get excellent answers from the respected scholars and researchers, but I have some notes for you. Unlike the M.Sc, the PhD must present significant contribution(s). Therefore, you need to identify a hot topic and an important point of an insufficient research coverage. From this start, you can define an initial possible contribution or list of planned contributions; however, your background and major will usually define the scope and approache(s) of study. You already defined the theme of your research i.e. renewable and sustainable energies. You need then to do an elaborated survey and to identify your favorable point of research. A research coverage matrix extracted from the survey can be very helpful in identifying the focal point of the research. Good luck

Good answers have been written. Just to add something, I have recently encountered irrigation systems. I did not really know that it is such a broad topic. I encountered a chapter on the topic of "renewable energy in irrigation systems". I guess it can be an interesting topic.
I definitely agree with Mohanned al shimy. In addition, You cannot just choose a broad topic without knowing what possible contributions you can make and what you are actually researching. It is not just about literature review
I also have similar challenges in the same topical area and I want to thank all the good people who av been contributing.... Looking forward to more SUGGESTIONS
