NREL Dedicates New Hydrogen Fueling Station at the ESIF
On October 8, NREL dedicated its 700 bar hydrogen fueling station at the Energy Systems Integration Facility (ESIF)the first station of its kind in Colorado and in the national lab systemas part of a celebration of National Hydrogen and Fuel Cell Day.
The fueling station is part of NREL's new Hydrogen Infrastructure Testing and Research Facility (HITRF), where scientists will be able to produce hydrogen through electrolysis, test fuel cell vehicle and infrastructure components and systems, and improve renewable hydrogen production methods.

"Little Box Challenge" Inverters Arrive at NREL for Testing
On October 21, each of the 18 finalists in the Little Box Challenge presented by Google and the IEEE Power Electronics Society brought their inverters to NREL's Energy Systems Integration Facility (ESIF) to begin testing and evaluation. The day also included each team describing the highlights of its design and lessons learned to a team of researchers and engineers from Google, IEEE, NREL, and others in the power electronics industry.
NREL researchers have collaborated with Google and IEEE to assist in designing the specifications and evaluation methodology for the prototype inverters; each inverter's efficiency and performance will be evaluated using the same set of typical operating conditions spanning 100 hours. Each inverter must be able to meet most of the same specifications required of inverters already available commercially. More than 100 teams submitted technical approach documents and testing applications.
The test results will help Google and IEEE decide the winner of the $1 million prize. To be successful, teams will have designed and built a residential-scale inverter with the highest power densityat least 50 watts per cubic inch. Currently, inverters are about the size of a picnic cooler, and Google would like to see the technology shrink to the size of a small laptop computer, or smaller. Shrinking the inverter by 10 times or more and making it cheaper to produce and install would enable more solar-powered homes, more efficient distribution grids, and help bring electricity to remote areas.
The grand-prize winner will be announced sometime in early 2016.

ESIF HPC System Expands for Increased Computing Power
Peregrine, the flagship high-performance computing (HPC) system at NREL's Energy Systems Integration Facility (ESIF), is expanding to have an additional 1,152 nodes, each of which will have two of the new Intel E5-2670v3 Xeon "Haswell-EP" processor chips and 64 GB of memory. These new nodes will bring the aggregate peak performance of Peregrine to 2.2 PetaFLOPS. The new nodes will be integrated into the system's high-speed Inifiniband network as two 576-node "scalable units," which will increase the maximum number of CPU cores that a single job can use from 6,912 cores to 13,824 cores. This expansion nearly doubles the number of node hours available for project allocations.

NREL Hosts High-Pen PV Workshop, Greentech Media Grid Edge Meeting This Month
NREL hosted two events with industry at the Energy Systems Integration Facility (ESIF) this month.
- On October 22 and 23, NREL hosted a workshop showcasing the latest research and advanced technologies for integrating high penetrations of PV in distribution grids. Stay tunedworkshop materials will soon be posted on NREL's ESI website.
- On October 27, NREL hosted Greentech Media's Grid Edge Executive Council meeting on the topic of renewable integration at the grid edge. Discussions focused on examining the top drivers of renewable integration and the technology currently available to facilitate rapid grid connectivity. Other topics include identifying downstream impacts of more grid-connected renewables and some of the regional efforts currently underway.

NREL's Enhanced Scenario Framework for Electricity Sector Analysis Provides Cost, Performance Data
Projections of potential energy futures are highly dependent on the assumptions associated with specific technologies, market conditions, and energy policies. A new framework from NREL that includes generation technology cost assumptions and an ensemble of future scenarios is being used to improve the robustness and comparability of electric sector analysis by the lab, academia, and other entities in the energy analysis community.
NREL's Annual Technology Baseline (ATB) and Standard Scenarios have been used to inform U.S. region inputs to the International Energy Agency's (IEA) and Nuclear Energy Agency's recent report on "Projected Costs of Generating Electricity 2015 Edition," as well as its ongoing World Energy Outlook analysis. The ATB is also cited in EPA's final Clean Power Plan rule as a source, recognizing the ATB as a current, consensus source for renewable cost and performance assumptions.

ESI in the U.S. and Around the World
iiESI Update: New Video, Thermal Energy Workshop in Korea
This month, the International Institute for Energy Systems Integration (iiESI) released a new video and hosted a workshop on thermal energy storage in Korea. iiESI is a global institute aimed at tackling the challenges of energy systems integration through collaboration and education.
- Watch the video on iiesi.org to learn more about this global collaboration from iiESI leadership and workshop participants.
- iiESI and the Korea Institute of Energy Research co-sponsored the workshop "ICT Enabling Thermal Energy Flexibility in Integrated Energy Systems" in Korea. The workshop followed the World Science and Technology Forum, hosted by the Ministry of Science, ICT, and Future Planning of the Republic of Korea on October 21-22. Workshop materials will soon be posted on iiesi.org.

Energy Department Awards $6 Million to Universities to Advance Master's and Doctoral Training in Power Electronics
On October 8, the U.S. Department of Energy (DOE) announced the two universities selected to receive nearly $6 million to establish one or more graduate-level training programs for engineers in power electronics.
DOE selected the University of Tennessee, Knoxville to receive $2.9 million and Virginia Polytechnic Institute and State University (Virginia Tech) to receive $3 million to create masters or doctoral training programs that will enable the design, manufacturing, and deployment of advanced high-efficiency electrical equipment such as motors, inverters, and grid equipment, as well as high-efficiency electrical systems.
The training curricula in power electronicswhich control or convert electrical energy into usable powerwill include cutting-edge wide bandgap semiconductors that can operate at higher temperatures, voltages, and frequencies, and are more durable and reliable than silicon-based counterparts. The five-year traineeships programs will be implemented beginning in the fall 2016 school year and are concentrated on advanced power electronic equipment engineering, design, and manufacturing.

California's Largest Utility Commits $3B Annually to Grid Modernization
On October 19, Pacific Gas and Electric Co. (PG&E), California's largest utility and a partner in NREL's ESI research, joined a White House effort to rally business support for action on climate change, with the company's top executive taking part in a roundtable discussion with President Obama. PG&E joined 80 other companies who have signed onto President Barack Obama's American Business Act on Climate Pledge, pushing for action on climate change while making a case for stronger innovation on the business side.
The utility pledged to reach 60% carbon-free energy and said it will invest $3 billion annually through 2020 on grid modernization efforts.

Energy Department Invests More Than $34 Million to Improve Protection of the Nation's Energy Infrastructure
On October 9, the U.S. Department of Energy's (DOE) Office of Electricity Delivery and Energy Reliability announced more than $34 million for two projects that will help protect the U.S. electric grid and oil and natural gas infrastructure from cyber threats.
The University of Arkansas and the University of Illinois will assemble teams with expertise in power systems engineering and the computer science of cybersecurity to develop new technologies that will help protect energy delivery systems for continuous and reliable power. These universities and their partners will engage with utilities and suppliers of energy delivery systems and components from early research through eventual adoption by the energy sector.
