Why Long-Duration Energy Storage Matters

By Max Tuttman & Dr. Scott Litzelman Long-duration electricity storage (LDES) – storage systems that can discharge for 10 hours or more at their rated power–  have recently gained a lot of attention and continue to be a technology space of interest in energy innovation discussions. The increased interest stems from a growing appreciation and acknowledgement of the need for “firm” low-carbon energy resources to complement variable renewable generators like wind and solar[1], and ARPA-E is actively working to increase storage capacity to help fill this need. LDES is one of the…


Turning Ideas Into Reality - Projects in Progress III

ARPA-E focuses on next-generation energy innovation to create a sustainable energy future. The agency provides R&D support to businesses, universities, and national labs to develop technologies that could fundamentally change the way we get, use, and store energy. Since 2009, ARPA-E has provided approximately $2 billion in support to more than 800 energy technology projects. In January, we introduced a new series to highlight the transformational technology our project teams are developing across the energy portfolio. Check out these projects turning ideas into reality: Electroville…


ARPA-E - Enhancing Energy Security Through Defense Partnerships

One of the pillars of our mission here at ARPA-E is to enhance the economic and energy security of the United States. We do this by supporting the development of energy technologies that could potentially reduce energy imports from foreign sources, decrease energy-related emissions, and improve the energy efficiency of our nation’s economic sectors. Through strategic partnerships and collaborations with other federal agencies, we can help our awardees to further develop and prepare their technologies to eventually make the transition out of the lab and into the market. Over ARPA-E’s first…


Entering Deep Waters with ARPA-E’s First Ever “Ocean Week”

ARPA-E strives for excellence in both program development and program integration, to encourage new discussions and new perspectives.  This approach was on display at the recent ARPA-E “Ocean Week,” held from January 28-30, in Washington.  This three-day voyage into ARPA-E’s ocean-focused programs consisted of three events: The Macroalgae Research Inspiring Novel Energy Resources (MARINER) Program Review, the Aerodynamic Turbines Lighter and Afloat with Nautical Technologies and Integrated Servo-control (ATLANTIS) Program Kickoff, and a Submarine Hydrokinetic Industry Day.…

Complete Freedom and Flexibility: A Look Back on the ARPA-E Summer Scholars Program with David Zhang

With spring break just around the corner, ARPA-E is getting ready to welcome a new crop of energy enthusiasts to its annual Summer Scholars program. We reached out to a former Summer Scholar, David Zhang, to learn a little about his background, his experience at ARPA-E, and how it helped change the course of his career. Tell us a little about yourself! How did you become involved in the energy world? Growing up in the energy capital of the world – Houston, Texas – I’ve always been surrounded by the energy industry. I interned abroad during my sophomore year of college, designing…


Gone Fission with New Program Director Bob Ledoux

Newest ARPA-E Program Director Dr. Robert (Bob) J. Ledoux’s professional experience ranges from professor to entrepreneur and his patents from nonintrusive cargo inspection to medical technologies. Prior to joining ARPA-E, the Boston native founded Passport Systems, a cargo inspection technology company, where he served as director and CEO. Previous to that, he developed control algorithms and hardware used in semiconductor manufacturing equipment as vice president of Pyramid Technical Consultants—and before that was CEO of a medical instruments company that developed and brought to market…

Untapped Resources and New Horizons – The ATLANTIS Program

For thousands of years, civilization has been fascinated by the fabled lost city of Atlantis. Legend has it that the ancient city was a technologically advanced utopia filled with riches and wealth, and theories on the lost civilization speculate it’s reach extended far past the boundaries of the ancient Mediterranean world. While over the years skeptics have dismissed its existence as the stuff of myth and legend, explorers have nonetheless long searched for Atlantis. To this day, its story continues to serve as inspiration to those seeking to discover new frontiers and reach untapped…


ARPA-E: Innovating Through Unconventional Ideas

In 2019, ARPA-E announced an ongoing funding opportunity for a range of the most innovative and unconventional ideas across the energy technology spectrum, exploring high-risk R&D that could lead to the development of disruptive technologies. The topics explored under this opportunity are not part of existing ARPA-E programs, but if successful could establish new program areas for ARPA-E to further explore. Take a look at specific projects ARPA-E has funded under this opportunity across the broad range of technical areas outlined below. [collapsed title="Mining Incinerated Disposal…
