Details about the project:

The idea of the energy storage systems in general is to give the system any form of energy. So, you can get it back it any time. The idea depends on the oxidation of the water and the reduction of the Co2. To make these two processes you need an electric current which is 1.23 V for the oxidation and 1.14 for the reduction. The carbon dioxide will be got from the atmosphere of Venus. It will be filtered from the sulfuric acid by using a filter that is covered by Na2Co3 that will react with the sulfuric acid and will not let it through. So, the carbon dioxide will enter the cell alone. First what is the cell structure. The cell is made of two separated sides. These sides are separated by super ionic sodium membrane. The electrolyte that is used is a KHCO3 electrolyte pH 6.8. In the first side the water will be placed and the anode that is used will be the platinum. In the other side the cathode will be the Au (Gold). The Co2 will enter to the cathode side directly. The current which is (1.23V) will be added to anode which will oxidize the water to oxygen, hydrogen protons and electrons. This is the reaction of the anode . The reduction reaction of the Co2 depends on the binding energy between the cathode and the Co2. The only equation of the reduction exist was with the copper. Theoretically the Gold Cathode will reduce the Co2 to Co with high percentage, H2 and methanol with lower percentage. The Co and oxygen will go to the collector through a pipe. They will combine and generate electricity more than the input. All this cell will be in a container that is coated by ceramic fibers (insulation material) which will keep the temperature of the cell from the Venus temperature.

The benefits:

The gold was used because it will produce Co.

Th3e Co2 was used from the atmosphere.

Achieving:

the cell can work for 60 days

.

1-It was a great experience as it developed our responsibilities to end the work before the time and make good quality in a perfect time also this experience makes us depend on ourselves because we were outside our home for 2 days without my family so we must find a way to dealing with people without our families help.

2-As Venus is a mystery in the space exploration field because all the previous explorations were not successful as the rovers were not able to withstand the high temperature and the energy source was not sufficient so we were seeking to find a solution that can withstand the high temperature and at the same time be a sufficient source of energy

3- Our goal was to make an energy storage system that can last for 60 days on Venus however the harsh environment like the high temperature and pressure.

4-From the difficulties the overheat on Venus we got metals with a high specific heat capacity like titanium also there was a problem that how we will transfer gas to the collector so we made tubes the gas will go throw it to the collector

5-Everyone in our team must be thanked because everyone works hard with all of his passion and end the work before deadline.
