11 Feb. SCO power/energy group

Present: Tracy, Jay, Jack, Bob, Dave, Renee, Jen, 2 others.
Tracy leads.
– DOE AFFECT grant proposals. CPS is in good shape for getting the
proposal ready and in. Letters of support are in for RAPID
proposal. Tracy notes this will be not only a power system but also
a communications system, so SRI is an appropriate partner. Tracy is
on target to deliver on schedule. Jack points out that there is no
detailed description of the budget and/or NSF cost sharing, which he
reads as a critical link. The new proposal shows a breakdown, and
the NSF commitment is implicit. Tracy reminds Renee that an agency
(NSF) letter of commitment is a hard requirement for the proposal.
There is some discussion of combining micro-turbine proposals
between the Antarctic and Arctic. There was a waste-to-energy plan
for the Antarctic program, but it sounds like there is not enough
waste to justify the investment (aside). CPS is working on a
life-cycle cost analysis for the CHP proposal. Jen is currently
custodian of the proposal. There is a need for getting the numbers
into the proposal.
– Summit/ISI Grid concept- Tracy asks for comments on the conceptual
drawings, no comments. Next looking for consensus on system
definitions. Looking at 4160 or 15 kV as the line level for the
power line from ISI to Summit. Cable costs have come in, and are
dramatically lower than what we thought earlier. Somewhere around
$30k. This makes it sound quite reasonable for running such a
line. Sounds like it’s looking more like 4160V as it’s more
accessible. Tracy asks SCO if it is pretty reasonable to eliminate
the “manholes” that they used at South Pole. Bob points out that
there are horizontal strain (divergence) data for the Summit area,
and so we should be able to calculate what kind of strain a cable
would have to withstand for a lifetime of 30 years. Question of the
period of autonomy- how much storage? And also looking at the
different battery technologies.
– Other agenda items. requests for new agenda items?
– Jack asks if Fuel cells are any part of the picture for Summit.
Sounds like it may be a challenge “a little risky”. Jack points out
that we need to be pushing the envelope and take leadership on
showing that these things can be done. Not betting the station on
it or anything, but getting things started.
– Tracy has tried to get NREL back in with the group, to no avail.
