Hello Kirk,
we wish you two a happy new year! Thank you for your answer.
So we´re going to analyse Option 1: Electrolyte-membrane interactions. Therefore, we make a LCA, which includes transportation, production and use-phase.
We have some more questions:
- Friendly reminder to answer the general questions mentioned in our previous blog post:
General questions:
• How much energy supply does a RFB require (for one cycle/in total)?
• Which electricity mix is currently used to operate the battery (is there a proportion of green electricity)?
• Where are the materials purchased? From which countries are they delivered and how (train, car, ship)?
• In which country are the batteries assembled and tested?
-
Do you have any data of the composition and volume of the electrolyte of the large-format cell design? Or should we scale up the chemicals from the 2 cm² RFB to the 175 cm² RFB?
◦ Electrolyte composition: 4M KI, 2M ZnCl2, 1M NH4Cl in deionized H2O
→ Is M equivalent to mmol/L or mol/L?
◦ Electrolyte volume: 5 mL (anolyte) + 5 mL (catholyte) -
Do you have an assumption for how many cycles the matte photo paper could last?
-
How long do the tests of the RFB last (in minutes/hours)? We need this information to calculate the power consumption.
We would gladly like to accept your offer of building columns for weight, manufacturing process, and material, into the BOM of the project.
We look forward to hearing from you.
Kind regards,
Rieke Huesmann, Anita Thaqi, Stella Vucemilovic
