Second five years was $42.5 million
We will see more “directed” research of the core funding
NGIPS
Challenge Problems
Special Teams
We will have additional funding through “ESRDC Technology”
T-Craft
Compact Power Conversion
Participation on key standards committees and task forces

8. More “directed” research
NGIPS – three major architectures

15. Technology Evaluations
Funded outside and in addition to the ESRDC core grant
Utilizing the ESRDC grant mechanism
Fast turnaround and time limited
May exclude non-US citizens/persons
Requires NDAs with industry
Present projects:
T-Craft – leader –Jon Herbst - UT
Compact Power Support – leader – Dave Cartes FSU

16. T-Craft University of Texas/CEM has lead role
John Herbst PI, Ferenc Bogdan (FSU) co-PI
Evaluated proposals from 3 vendors
Alion
Umoe-Mandal
Textron
Final report submitted to ONR early October
New proposal for Phase II submitted April 09

17. ESRDC Engagement in Standards and Practices Activities
IEEE 1547 – DG Interconnection
CIGRE, FCL Testing Task Force
IEEE P Power Electronics on Ships
IEEE MVDC systems for ships
IEEE I 8 - PEBB working Group
TF 1 Universal Controller
TF 2 Tools for PEBB systems design
IEEE PES Marine Systems Coordinating Committee
IEEE 45 – ship electric power systems installation

18. Market
The Naval Sea Systems Command has established the Electric Ship Office (ESO) to lead the development of advanced technologies and components that will improve operating efficiency of current ships, enhance the capabilities of the existing integrated power system that was designed for the DDG 1000, and produce the Next Generation Integrated Power System (NGIPS) for future ship classes.
Electric Ship is on list of proposed Innovative Naval Prototype for 2012
As ONR-sponsored research in power and energy systems begins to diminish, ESO and the related new ship acquisition programs will become increasingly strong potential markets.
High-energy and directed-energy systems are being pursued as possible future offensive and/or defensive ship weapons. Their development involves participation by offices outside of PEO (Ships) and the ESO
The new administration is pushing for stronger interactions on energy research between agencies

19. Risks
Available future funding. - Fully funding the ESRDC Grant would require 100% of currently available funds at ONR and it’s unlikely that ONR would be able or willing to sustain that beyond the present grant.
Cancellation of DDG-1000 – There is a strong possibility that this Class will be limited to 3 ships and that 8-11 additional DDG-51 Class ships will be built instead with “applicable Zumwalt technologies” This could negate the need for continuation of development of new technologies for insertion into the existing IPS architecture resulting in significant reduction in near- term funding.
CG(X) Is Not All-Electric – One option that is being considered for CG(X) is nuclear propulsion with a mechanical drive transmission. If this option is selected, NGIPS will be either cancelled or significantly delayed

20. Risk
Innovative Naval Prototype. - Electric ship program will not be selected as an NIP
Naval Laboratories – The appearance of competition with naval laboratories for tasks that have traditionally fallen within their charters will make it difficult or impossible for work to be awarded to ESRDC. This is particularly critical for efforts from NAVSEA that may appear to be within the scope of NSWC.

21. ESRDC Value Proposition to the Navy

25. Discussion
Are there factors from the market that should make us radically reevaluate our proposed approach
Are the thrusts as defined in our proposal still appropriate
What should be the core elements in our FY 10 SOW
How do we approach the MVHF architecture
Who takes ownership
How do we approach the challenge of expanding to include utility electric grid in research portfolio
