Executive Summary

ARPA-E's UNLOCK program (Unlocking New Levels of Output and Capacity for Key Subsurface Resources) funds technologies that double per-well recovery of oil, gas, geothermal heat and minerals from low-permeability rock while holding or cutting per-unit cost and wastewater. ARPA-E issued two notices on October 21, 2026: DE-FOA-0003630 for universities, national labs and companies of any size, and DE-FOA-0003631, an SBIR/STTR version for small businesses. About $45M is shared between them for 9 to 12 awards.

Every project must combine a new stimulation or recovery method with integrated sensing and modeling, then prove it at a real field site with the site operator on the team. Concept papers are due November 20, 2026, 9:30 AM ET.

What Is UNLOCK?

UNLOCK is an ARPA-E program to deliver a step change in energy and critical resource extraction from the subsurface. It targets formations where low permeability keeps most of the resource in the ground. ARPA-E wants approaches that integrate stimulation and enhanced recovery with sensing and modeling, validated in the lab and then in a field trial at well scale.

What Problem Is ARPA-E Trying to Solve?

ARPA-E notes that shale and tight formations supply most U.S. oil and gas, yet more than 80% of the resource stays trapped and well output can fall by up to half in the first year. Fracturing uses millions of gallons of water per well, and current diagnostics give limited views of fractures and fluid flow. Enhanced geothermal, in-situ mineral leaching and coalbed methane face similar permeability, monitoring and water problems.

Priority Technical Areas: What ARPA-E Is Looking For

• Category A, Shale and Tight Oil & Gas: ARPA-E expects most selections here.
• Category B, Other Low-Permeability Subsurface Resources: enhanced geothermal systems, in-situ leaching of minerals and metals, and coalbed methane.
• Waterless or low-water stimulation: energized gas injection (supercritical CO2, nitrogen), chemical stimulation, electric discharge and pulsed plasma fracturing, high-energy laser stimulation, thermal and acoustic stimulation, self-propagating fracture networks.
• Advanced recovery fluids: supercritical, nanoparticle-enhanced or microbe-assisted fluids; adaptive, responsive or phase-changing fluids such as temperature- or pressure-activated gels.
• Engineered proppants: shape-adaptive, reactive, catalytic, in-situ generated, multifunctional (sensing, scale-inhibiting) and high-temperature stable.
• Diagnostics and modeling: distributed chemical sensing, quantum sensors, swarm-based sensors, micro-sensors and integrated experimental validation.

Funding and Cost Share

• Two phases: about 18 months of laboratory validation, then about 18 months of field testing. Both are funded at the start, but moving to Phase 2 is a portfolio-wide down-select.
• Cost share under 0003630: at least 20% of total project cost for most teams; 5% for a standalone U.S. university or nonprofit, or a team made up only of universities, nonprofits and FFRDCs/national labs.
• Small businesses under 0003630: 0% for the first 12 months, then at least 10% of total project cost (including the first year) if the project continues.
• SBIR/STTR notice 0003631: no cost share required.

Eligibility

• 0003630: U.S. universities, national laboratories, for-profit companies of any size, nonprofits, and individuals who are U.S. citizens or permanent residents (funding goes to an entity they form). Consortia need a U.S.-incorporated representative.
• 0003631: small business concerns only. STTR needs one research institution doing 30% to 60% of the work.
• One lead only: a small business can lead under only one of the two notices. ARPA-E strongly encourages small businesses to use 0003631.
• Foreign participation: requires a Foreign Entity Waiver. Work must be performed in the United States.

How to Apply

• Register in DOE eXCHANGE now.
• Line up the field site: identify the test site, document access with a letter of commitment, put the site operator on the team for both phases and describe the permitting path.
• Write the concept paper: Sections 1 to 4 in up to 4 pages, a 1-page section on the variables behind your metrics, a one-slide summary and the category-specific techno-economic analysis template.
• Submit through DOE eXCHANGE by November 20, 2026, 9:30 AM ET.
• Ask questions only through ARPA-E-CO@hq.doe.gov by November 10, 2026. ARPA-E is in a quiet period.

What Happens After You Submit?

• About January 5, 2027: encourage or discourage notices.
• Full applications: date to be announced, followed by reviewer comments and a reply.
• About April 2027: selection notices.
• About July 2027: awards and project start.

Is This Opportunity a Good Fit for Your Company?

Strong fit for oilfield and geothermal technology companies, specialty chemical and nanomaterial startups, proppant and advanced materials makers, plasma, laser and pulsed-power developers, downhole and quantum sensor companies, reservoir modeling and AI teams, and produced-water treatment companies that can partner with an operator. Weak fit for teams without a realistic path to a field site in this cycle, or with technology too early for a downhole trial. Early-stage teams can join a stronger team as a subrecipient.

How BW&CO Can Help

BW&CO has helped deep-tech and dual-use founders secure more than $350M in non-dilutive funding. For ARPA-E programs like UNLOCK, we help you:

• Test fit and choose between the open and SBIR/STTR notices
• Build the operator, field-site and research partner team
• Set metrics and targets that hold up to ARPA-E review
• Write a 4-page concept paper that earns an encourage notice
• Plan the full application, budget and cost share

Frequently Asked Questions

Is UNLOCK only for oil and gas?

No, but ARPA-E expects most selections in Category A, shale and tight oil and gas. Category B covers geothermal, mineral leaching and coalbed methane.

How much funding is available?

About $45M across both notices for 9 to 12 awards. Awards under 0003630 run $3M to $5M in federal share.

Do I need a field site?

Yes. Every team needs a field test site, documented access and the site operator on the team for both phases.

Is cost share required?

Yes under 0003630, at rates that depend on who leads. No under the SBIR/STTR notice 0003631.

Can a small business lead under both notices?

No. A small business can lead under only one of the two.

Can foreign companies take part?

Only with a Foreign Entity Waiver, and all work must be performed in the United States.

How long is the concept paper?

Sections 1 to 4 are capped at 4 pages, plus a 1-page variables section, a one-slide summary and the TEA template.

When are full applications due?

ARPA-E has not set the date. Encouraged teams will be told after the January 2027 notices.

Can BW&CO help with an UNLOCK submission?

Yes. BW&CO can test fit, help you choose between the two notices, build the operator and field-site team and write the concept paper. Book a call with our team.
