Efficient, Compact, Manufacturable, and Durable: Next-Generation Heat Exchangers

August 9, 2018 Last fall, ARPA-E Program Director Dr. Mike Ohadi led a workshop to explore innovative, high efficiency, modular electricity generation systems. You can read more about Dr. Ohadi’s background, what brought him to ARPA-E, the original goals for the workshop and some initial post-workshop thoughts in the original blog here. Having gained a better understanding of the challenge of efficient heat transfer, Dr. Ohadi sat down to chat about how his thinking surrounding both the problem and solution has evolved—and how the broader research community could help find a solution…


Keeping your cool with ARPA-E

July 10, 2018 Summer is in full swing, and for many Americans that means high temperatures and even higher electric bills. The amount of energy used to heat, cool and ventilate buildings in the United States is enormous, equivalent to approximately 13% of the country’s annual power use.[1] This is in part due to how inefficient environmental systems can be, which results in significant power wasted or lost. But as anyone who’s spent a summer in Florida, or a winter in Wisconsin, knows, heating, ventilation, and air conditioning (HVAC) are often essential to comfort and health. HVAC…


Control Co-Design

June 20, 2018  Control Co-Design: Concurrent Control Engineering for Optimal System Design ARPA-E Program Director Dr. Mario Garcia-Sanz discusses his background and upcoming workshop.   1. You are leading an upcoming workshop entitled “Control Co-Design for Wind and Marine-hydro-kinetic systems” – what is “control co-design”?  Control engineering is the application of mathematics, physics and technology towards autonomous control of physical systems. Control engineers take data about system status and performance, and use microprocessors, algorithms, circuits and…


Exploring Machine Learning-Enhanced Energy-Product Development with Dr. David Tew

June 13, 2018 Dr. David Tew joined ARPA-E as a Program Director in 2016 after nearly 20 years at United Technologies Corporation. His research focus at ARPA-E includes combined heat and power systems, industrial processes, and transportation energy efficiency. Dr. Tew delivered a Fast Pitch on Machine Learning-Enhanced Energy-Product Development at the 2018 ARPA-E Energy Innovation Summit. Now, he is leading a workshop on the topic to engage the broader research community.  Dr. Tew delivering his fast pitch at the 2018 Summit 1. In one sentence, can you tell us what this workshop is…


Three Technologies to Think About on your Commute: Improving the Future of Transportation

May 17, 2018 1. Is your gas light on again? ARPA-E’s Achates Power, Inc. team is working with Argonne National Laboratory and Delphi Powertrain to develop innovative technologies to improve gasoline efficiency in automobiles. Under its OPEN 2015 Award, the Achates team has successfully designed a new engine that is 30-50% more efficient than conventional gasoline engines without raising the engine’s cost. The team integrated a gas compression ignition (GCI) strategy with an opposed piston (OP) engine architecture. The OP engine design offers efficiency improvements as it reduces…


Building a More Resilient Grid in Puerto Rico

May 9, 2018 Cross-posted from the Energy.gov blog.   When Hurricane Maria struck the U.S. territory of Puerto Rico last September, it took the entire island’s power grid with it.   Today, over 95 percent of the island has its power restored, but the rebuilding process is far from finished. Over the long term, many challenges remain — along with some big opportunities to make the grid smarter and more resilient. The Puerto Rico Electric Power Authority (PREPA) manages the island territory’s grid and serves millions of customers. Now, they’ve set out to rebuild it better than…


ARPA-E Goes to EarthX

April 25, 2018 They say everything is big in Texas, and at this year’s EarthX event, it certainly felt that way. ARPA-E joined a trio of its awardees for this year’s conference, a massive expo in Dallas focused on energy, the environment, and new technology to solve some of our most pressing problems. ARPA-E’s mission has innovation at its core, so EarthX was a prime opportunity to showcase some of the agency’s most exciting energy projects while helping the public better understand ARPA-E’s mission and the role of energy in Americans’ everyday lives. UHV Technologies: X-Ray Enhanced Scrap…


Showcasing America’s Future Energy Tech at the 2018 ARPA-E Energy Innovation Summit

April 5, 2018 Three weeks ago, nearly 1,800 energy innovators, investors, and policymakers gathered at the ninth annual ARPA-E Energy Innovation Summit to discuss cutting-edge energy technologies, and how to best transition technologies out of the lab. During the three-day program, attendees from across the U.S. and 15 other countries heard from industry and government leaders, networked at focused receptions and panel discussions, and saw first-hand nearly 300 technologies featured in ARPA-E’s Technology Showcase. This year’s showcase featured technology-focused tours and six technology…


Recap of Day Three at the 2018 ARPA-E Energy Innovation Summit

March 16, 2018  The final day of the 2018 ARPA-E Energy Innovation Summit kicked off with a networking breakfast for the electrochemical flow cell community. Electrolytic components such as membranes, catalysts, MEAs and full electrolytic systems are critical to assemble world class flow cells, fuel cells and electrolyzers, yet they can be isolated in their individual technology silos. This opening session was a chance for this diverse community to connect with commercial and technical colleagues, compare notes, and potentially plan future collaborations, projects and partnerships.…


Recap of Day Two at the 2018 ARPA-E Energy Innovation Summit

March 15, 2018 Highlights from day two of the 2018 ARPA-E Energy Innovation Summit included video greetings to Summit attendees from Energy Secretary Rick Perry and Senator Lamar Alexander, remarks from Senator Michael Bennet and Michael Kratsios, White House Office of Science and Technology Policy, and a keynote from Tim Holt, CEO of Siemens Power Generation Services.
