DEPARTMENT OF ENERGY


Notice of Request for Information (RFI) on Supercritical Carbon 
Dioxide Power Cycles Integrated With Thermal Energy Storage

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of 
Energy (DOE).

ACTION: Request for Information (RFI).

-----------------------------------------------------------------------

SUMMARY: The U.S. Department of Energy (DOE) invites public comment on 
its Request for Information (RFI) number DE-FOA-0002182 regarding 
Supercritical Carbon Dioxide Power Cycles Integrated with Thermal 
Energy Storage. The purpose of this RFI is to solicit feedback from 
industry, academia, research laboratories, government agencies, and 
other stakeholders on methods to integrate and demonstrate 
supercritical carbon dioxide power cycles with thermal energy storage 
that operates in the temperature range between 565 and 670 [deg]C. The 
focus is on the integration of subsystems at temperatures that can 
enable near-term commercial deployment.

DATES: Responses to the RFI must be received by 5:00 p.m. EST on 
December 18, 2019.

ADDRESSES: Interested parties are to submit comments electronically to: 
[email protected]. Include Supercritical Carbon Dioxide Power 
Cycles Integrated with Thermal Energy Storage or sCO2 TES 
Integration, in the subject of the title. Only electronic responses 
will be accepted. The complete RFI document DE-FOA-0002182 is located 
at https://eere-exchange.energy.gov/.

FOR FURTHER INFORMATION CONTACT: Questions may be addressed to Rajgopal 
Vijaykumar at telephone (202) 287-1817 or by email 
[email protected]. Further instructions can be found in the RFI 
document posted on EERE Exchange.

SUPPLEMENTARY INFORMATION: This RFI seeks feedback on technologies to 
integrate and demonstrate advanced supercritical carbon dioxide (sCO2) 
Brayton power cycles that are indirectly heated via thermal energy 
storage at a turbine inlet temperature (TIT) range between 550 and 630 
[deg]C. This request is focused on accelerating the commercialization 
of sCO2 power cycles that are appropriate for near-term integration 
with concentrating solar-thermal power (CSP), at temperatures that do 
not require significant de-risking of the cost and performance of novel 
materials. The RFI DE-FOA-0002182 is available at: https://eere-exchange.energy.gov/.

Confidential Business Information

    Pursuant to 10 CFR 1004.11, any person submitting information that 
he or she believes to be confidential and exempt by law from public 
disclosure should submit via email two well marked copies: One copy of 
the document marked ``confidential'' including all the information 
believed to be confidential, and one copy of the document marked ``non-
confidential'' with the information believed to be confidential 
deleted. DOE will make its own determination about the confidential 
status of the information and treat it according to its determination.
    Factors of interest to DOE when evaluating requests to treat 
submitted information as confidential include: (1) A description of the 
items; (2) whether and why such items are customarily treated as 
confidential within the industry; (3) whether the information is 
generally known by or available from

[[Page 63864]]

other sources; (4) whether the information has previously been made 
available to others without obligation concerning its confidentiality; 
(5) an explanation of the competitive injury to the submitting person 
that would result from public disclosure; (6) when such information 
might lose its confidential character due to the passage of time; and 
(7) why disclosure of the information would be contrary to the public 
interest.

    Signed in Washington, DC, on October 21, 2019.
Rebecca Jones-Albertus,
Acting Director, Solar Energy Technologies Office.
