1. Underground Compressed Air Renewable Energy
Storage (UCARES)-
Structuring for a technical and financial analysis.

2. A financial comparison based on technical analysis, between en-
ergy provision at POR(Port of Rotterdam) without UCARES and
with UCARES. The comparison will also cater for system
scalability scenarios.
e.g.
Find out whether it is possible to produce more electricity using
the heat generated by air compression and delivering this heat to
the existing heat exchange system at POR.

Immediate Concerns
II.a
Without UCARES:
What is the peak hours energy price of the present system?
With UCARES:
Can UCARES be connected at POR to the grid?
If it can be connected, what is the cost of the system, CAPEX &
OPEX?
While in operation, how can the system i.e. UCARES + clients,
keep the stored energy within the ‘Island Mode’?
Heat Exchange:
Does the heat generated due compression has a value?

3. If the price for peak energy for the present system, is not available, how the assumptions
are made, and what is kept in consideration?
Which component of UCARES shall be connected to the grid? What are the standards
to connect on grid side? & which component of UCARES shall be connected to the cli-
ent? What are the standards to connect on client side?
To calculate CAPEX, what are the prices of preferred components?
To calculate OPEX, what are the life expectancy/maintainance costs of the components?
How does ‘Scalability’ effect the cost?
Incase of more than one client, how would the connections be made? What is the grid
topology, in regards to Island mode operation?
What are the risks involved in applying such topology at POR? Reliability, protection
and automation risks?
Does the matlab/simulink simulation give substantial results, can the system operate
according to above decided standards and topologies?
Is the heat generated by compression enough to be injected in the system?

Secondary
Find out how power consumtion profile of energy of an industrial client is logically assumed? Incase data
is not provided.
What are the standards of connection carried out at POR? What are the standards of connection in Eu-
rope?
What are the preferred components and which standards do they comply with?
What is the best geological postion for UCARES at POR? - Optimzation?
Who are the interested clients?
What are their peak energy costs? If not whole power profile, could a number be acquired?
Research on CAPEX/OPEX, finding references and learning how can such an analysis be made. Find out
whether the prices of components could be known? Analysis for possible client scenarios vis-a-vis scala-
bility scenarios?
How does ‘Island Mode‘ system work?- Research. Are there any standards for Island mode operation?
How does the distribution network at POR look like? Where can UCARES be connected?
Are there any protection and reliability risks? Research the kind of problems that may occure after
UCARES application.
Implement the findings in Matlab. Find out whether there are any simulation issues with the connections,
topology, transmission and distribution of energy in the system.
Learn how to calculate the heat generated by the air compression, learn how that heat can be transported
to the heat exchange system, learn how heat exchange work. Learn if the generated heat could be trans-
ported in given scenario to the heat exchange system at POR. Would it be of any value to the system?
What is the minimum heat required to be inducted in the system?
