The REMEDY for Methane Conversion

ARPA-E's REMEDY (Reducing Emissions of Methane Every Day of the Year) program is a three-year, $35 million research effort aimed at reducing methane emissions from three specific point sources from the coal, oil, and gas sector. These three sources are responsible for 10% of anthropogenic methane emissions. REMEDY seeks technical solutions that can achieve 99.5% methane conversion and commercial scalability. If successful, REMEDY systems could dramatically reduce U.S. greenhouse gas (GHG) emissions at low cost. ARPA-E Program Director Dr. Jack Lewnard leads the REMEDY program and focuses…

The REBELS of Distributed Power

Fuel cells use the chemical energy in fuels to produce clean, safe, and efficient electricity. Fuel cells can also be used to provide distributed power generation (DG), which refers to electricity generation located at or near the site where it will be used. Efficient, fuel-flexible, cost-competitive DG systems provide reliable stationary combined heat and power (CHP) for a variety of applications, including commercial buildings and data centers.  There is a critical need to develop fuel cell technologies that can enable DG at low cost and with high efficiency. These technologies have…


ARPA-E Investor Update Vol. 5

On September 7, 2021, WHOOP launched its latest wearable fitness device, WHOOP 4.0, which will feature Sila Nanotechnologies’ new battery technology. Their technology replaces graphite anodes with silicon (Si) to increase the energy density of lithium-ion (Li-ion) batteries, which can reduce battery size without sacrificing safety or performance. Sila Nanotechnologies’ anode technology helps enable the WHOOP 4.0’s slim design.   Compared with the previous model, the WHOOP 4.0 has…


Fusing for Further Advancement: Introducing the ARPA-E Fusion Capability Teams

Over the past several years, ARPA-E has funded a number of fusion “capability teams” through the Fusion Diagnostics “Exploratory Topic” (2019) and the BETHE program (2020) to accelerate fusion-energy R&D via public-private partnerships. These capability teams, drawing predominantly from federally funded researchers at U.S. national laboratories and universities, bring state-of-the-art tools (including diagnostic instruments and computational modeling) and expertise to help ARPA-E-supported fusion concept teams (and other federally and privately supported fusion teams) accelerate progress…


ARPA-E Announces Over $9 Million in Funding to Technology Projects Working to Remove Harmful Greenhouse Gas From U.S. Power Grid

Today, the U.S. Department of Energy’s (DOE) Advanced Research Project Agency-Energy (ARPA-E) announced it selected four projects to receive a combined $9.4 million to develop technology focused on removing sulfur hexafluoride—a significantly more potent greenhouse gas than carbon dioxide—from the U.S. power grid. The four projects selected to receive funding include the University of Connecticut in Storrs, Conn.; Georgia Tech in Atlanta, Ga.; GE Grid Solutions, LLC in Charleroi, Pa.; and Toshiba International Corporation in Houston, Texas. “The climate crisis is already devastating…


Announcing Grid Optimization (GO) Competition Challenge 2 Winners

The Grid Optimization (GO) Competition—managed by ARPA‑E—is a series of challenges aimed at developing software management solutions to address challenging power grid problems. The competition’s intent is to create a more reliable, resilient and secure American electricity grid.  The GO Competition began with Challenge 1, which tasked participating teams to find solutions to a security constrained optimal power flow (SCOPF) problem. Challenge 2 expands upon the SCOPF problem posed in Challenge 1 by adding new features including transmission line switching, adjustable…


NIFty and SPARCly: Recent Achievements in Fusion

On August 17, 2021, a New York Times article proclaimed a fusion energy release of 1.3 megajoules from 1.9 megajoules of incident laser energy, achieved at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. The announcement of such a significant physics result rocked the fusion world, renewing discussions on R&D to enable commercially viable embodiments of laser-driven inertial confinement fusion (ICF). While the NIF result equals the decades-old record tokamak scientific…


REPAIR Program Update: An Ounce of Prevention is Worth a Pound of Cure

ARPA-E has kicked off a 3-year, $38M research program called REPAIR (Rapid Encapsulation of Pipelines Avoiding Intensive Replacement) to rehabilitate cast iron, wrought iron, and bare steel natural gas distribution pipes. The goal of the program is to use robots to create a new pipe inside the old pipe. For the program to be successful, the new pipe must meet utilities and regulatory agencies’ requirements, have a minimum life of 50 years, and possess sufficient material properties to operate throughout its service life without relying on the exterior pipe. Considering that gas utilities have…


Refueling Carbon Neutral Liquid Fuel Development with REFUEL+IT

Working to find outside-the-box solutions that address existing limitations of energy technologies is a unifying goal among many ARPA-E programs. A core aspect of our mission is to look at how we can develop new materials, new processes, and new technologies to solve complex problems, with a particular focus on decreasing carbon emissions across a range of energy applications. One such space that ARPA-E identified for impact back in 2016 was the development of manufacturing low-carbon, renewable liquid fuels that are cost and performance competitive with existing petroleum-based fuels.…


The Heat is ON this Summer at ARPA-E

It’s July, and it being the middle of Summer means temperatures are rising and Americans across the country are doing their best to manage the heat in different ways. While people in business and residential spaces seek to keep temperatures as cool and comfortable as possible and electricity costs low (check out this throwback blog about some ARPA-E projects working to do just that), managing heat and thermal energy is also extremely important in almost every aspect of energy technology development. Heat itself - or more specifically thermal energy - is involved in over 90% of all energy…
