ARPA-E to award up to $130M in fourth round of funding; focus on biofuels, thermal storage, rare earth alternatives, grid controls, and solar power electronics

The US Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E) will make up to $130 million available to develop five new program areas including biofuels, thermal storage, rare earth alternatives, grid controls, and solar power electronics. (Related Funding Opportunity Announcements here.)

In its first year, ARPA-E awarded $363 million in Recovery Act funding to 121 energy projects based in 30 states, with approximately 39% of projects led by universities, 33% by small businesses, 20% by large businesses, 5% by national labs, and 3% by non-profits. Six of its projects have secured more than $100 million in outside private capital investment.

ARPA-E’s fourth round of funding opportunities includes five technology areas detailed below:

  1. Plants Engineered To Replace Oil (PETRO). Technologies for low-cost production of advanced biofuels are limited by the small amount of available energy captured by photosynthesis and the inefficient processes used to convert plant matter to fuel. PETRO aims to create plants that capture more energy from sunlight and convert that energy directly into fuels. ARPA-E seeks to fund technologies that optimize the biochemical processes of energy capture and conversion to develop robust, farm-ready crops that deliver more energy per acre with less processing prior to the pump. If successful, PETRO will create biofuels for half their current cost, finally making them cost-competitive with fuels from oil. Up to $30 million will be made available for this program area.

  2. High Energy Advanced Thermal Storage (HEATS). More than 90% of energy technologies involve the transport and conversion of thermal energy. Therefore, advancements in thermal energy storage—both hot and cold—would dramatically improve performance for a variety of critical energy applications. ARPA-E seeks to develop revolutionary cost-effective thermal energy storage technologies in three focus areas: 1) high temperature storage systems to deliver solar electricity more efficiently around the clock and allow nuclear and fossil baseload resources the flexibility to meet peak demand; 2) fuel produced from the sun’s heat; and 3) HVAC systems that use thermal storage to improve the driving range of electric vehicles by up to 40%. Up to $30 million will be made available for this program area.

  3. Rare Earth Alternatives in Critical Technologies (REACT). Rare earths are naturally-occurring minerals with unique magnetic properties that are used in many emerging energy technologies. As demand for these technologies continues to increase, rare earths are rapidly becoming more expensive due to limited global supply—prices of many have increased 300-700% in the past year. Rising rare earth prices have already escalated costs for some energy technologies and may jeopardize the widespread adoption of many critical energy solutions by US manufacturers. ARPA-E seeks to fund early-stage technology alternatives that reduce or eliminate the dependence on rare earth materials by developing substitutes in two key areas: electric vehicle motors and wind generators. Up to $30 million will be made available for this program area.

  4. Green Electricity Network Integration (GENI). Recent advances in computation, networking, and grid monitoring have shed light on potential ways to deliver electricity more efficiently and reliably. Today, however, the equivalent of one out of every five electricity dollars is lost to power outages and 30 percent of the grid’s hardware needs replacing. ARPA-E seeks to fund innovative control software and high-voltage hardware to reliably control the grid, specifically: 1) controls able to manage 10 times more sporadically available wind and solar electricity than currently on the grid; and 2) resilient power flow control hardware—or the energy equivalent of an internet router—to enable significantly more electricity through the existing network of transmission lines. Up to $30 million will be made available for this program area.

  5. Solar Agile Delivery of Electrical Power Technology (Solar ADEPT). The DOE SunShot Initiative leverages the unique strengths across DOE to reduce the total cost of utility-scale solar systems by 75% by the end of the decade. If successful, this collaboration would deliver solar electricity at roughly 6 cents a kilowatt hour—a cost competitive with electricity from fossil fuels. This would enable solar electricity to scale without subsidies and make the US globally competitive in solar technology. ARPA-E’s portion of the collaboration is the Solar ADEPT program, which focuses on integrating advanced power electronics into solar panels and solar farms to extract and deliver energy more efficiently. Specifically, ARPA-E aims to invest in key advances in magnetics, semiconductor switches, and charge storage, which could reduce power conversion costs by up to 50% for utilities and 80% for homeowners. Up to $10 million will be made available for this program area.

The five technology areas announced today will join ARPA-E’s seven existing programs in power electronics (ADEPT); battery technologies (BEEST); building cooling (BEETIT); non-photosynthetic biofuels (Electrofuels); grid energy storage (GRIDS); carbon capture (IMPACCT); and its initial open solicitation.



Who is going to keep track and control achievement level of those 121 projects? How many will ever meet or even try to meet the initial goals?
How much money will be wasted or spent out of control?

Wouldn't it be a better idea to work with a lot less projects and have better controls over what is being achieved?


Were they all chosen because of the names?

Thermal storage has a big overlap with solar thermal, AA-CAES and load shifting (ice) as well as automotive applications.


I see the DOE as making up for 8 years of lost time when the PNGV program became the hydrogen Freedom Car decades away.

"Six of its projects have secured more than $100 million in outside private capital investment.'

The idea is to leverage private sector investment when they could make more on foreign T Bonds. Our government does not make direct investments, but rather grants and loan guarantees.

The private sector has always pushed for the right of first refusal on any and all deals and they usually refuse unless there is a killing to be made, but then it is too late.
