Idaho Field Office · $5K–$8M

This Department of Energy program (Idaho Field Office) provides cost-share grants to help offset the cost of licensing advanced nuclear energy reactors. Eligible applicants are broad and include federally recognized tribal governments, small and other businesses, county and city/township governments, nonprofits (including those without 501(c)(3) status, but not higher-ed institutions), and public and private universities. Awards range from about $5,000 up to roughly $8M, and applications are only accepted during a July 1 to September 30 window. Note this is a cost-share program, so applicants are expected to contribute matching funds.

Environmental Protection · Up to $500K

Pennsylvania DEP's Alternative Fuels Incentive Grant Program funds up to $500,000 for the incremental cost of purchasing or retrofitting vehicles to run on alternative fuels, such as RNG, LNG, CNG, propane, hydrogen, biodiesel blends over B20, or battery-electric. Eligible applicants include school districts, municipal authorities, political subdivisions, nonprofits, corporations, LLCs, and partnerships. The deadline is October 7, 2026.

Rural Business-Cooperative Service · $1.5K–$500K

Open to agricultural producers, the USDA REAP program funds renewable energy systems and energy efficiency improvements, with awards ranging from about $1,500 up to $500,000. Eligibility is limited to agricultural producers (and, under the broader REAP program, certain rural small businesses), so general applicants and urban organizations typically do not qualify. Review the application package and contact a State Energy Coordinator for required forms and current terms.

State Treasurer's Office · Amount varies

California businesses, nonprofits, individuals, public agencies, and tribal governments building or expanding a manufacturing facility involving recycled feedstock, advanced manufacturing, alternative energy, or advanced transportation technologies can apply to CAEATFA for a sales and use tax exclusion on qualifying equipment purchases. This is a tax exclusion rather than a direct cash grant, so applicants should confirm it fits their funding needs; no dollar cap or deadline is specified here.

CA Energy Commission · Amount varies

Businesses, individuals, public agencies, and tribal governments in California may apply for this CA Energy Commission program, which provides cost-share funding to match federal geothermal energy grants (energy, science, technology, and R&D projects). No award amounts or deadlines are listed here, and applicants should consult the program's application manual for full eligibility rules and required documentation.

Idaho Field Office · Amount varies

This is a Request for Information (not a funded opportunity) from the DOE Idaho Field Office, seeking input from universities, national labs, industry, nonprofits (with or without 501(c)(3) status), and small businesses on future nuclear energy research priorities, submitted via NEUP.gov. There is no monetary award tied to this notice. For-profit organizations other than small businesses are not eligible to respond as such.

CA Energy Commission · Amount varies

Open to businesses, individuals, nonprofits, public agencies, and tribal governments, but only to applicants who have already received (or are applying for) an eligible federal clean energy funding opportunity or qualifying DOE follow-on funding — this program provides matching cost-share funds, not standalone project grants. Retroactive cost share for already-received federal awards is not eligible. No set award amount or deadline is listed; eligibility depends on holding or pursuing a specific federal award first.

Rural Business-Cooperative Service · $1.5K–$500K

USDA's Rural Business-Cooperative Service Renewable Energy Systems and Energy Efficiency Improvements Program (REAP) funds agricultural producers for renewable energy and efficiency projects, with awards ranging from about $1,500 to $500,000. Eligibility is limited to agricultural producers rather than nonprofits or businesses generally, and applicants should contact their State Energy Coordinator for full application requirements.

Department of Resources Recycling and Recovery · Amount varies

Open to businesses, nonprofits, and public agencies in California, this program funds loans (not grants) to reduce greenhouse gas emissions, particularly landfill methane and upstream manufacturing emissions, with priority benefits for disadvantaged communities. No specific award amount or deadline is listed. Applicants should note this is a loan program, requiring repayment, rather than a non-repayable grant.

CA Energy Commission · Amount varies

Provides state cost-share funding to California businesses, individuals, and public agencies that are applying for a federal DOE clean hydrogen funding opportunity — it is only available alongside an active or pending federal award, not as a standalone grant. Applicants who already received federal funding and want retroactive cost-share are not eligible. No specific award amount or deadline is listed.

Idaho Field Office · Amount varies

This is a Request for Information from the DOE Idaho Field Office, not a funding opportunity; it asks nonprofits (with or without 501(c)(3) status), higher education institutions, state governments, and small businesses to submit comments on nuclear energy research priorities via NEUP.gov. No funding is attached (amount shown as $0), so responding does not itself lead to an award. Eligible respondent types are broad, but this is input-gathering only, not a grant.

State Treasurer's Office · $1.5M–$550M

A tax-exempt bond financing program (not a grant) for California businesses of any size involved in pollution control, waste disposal, recycling, composting, or resource recovery facilities; smaller businesses (500 employees or fewer) may also qualify under separate federal size standards. Financed amounts range from about $1.5 million to $550 million, with strict rules on how bond proceeds may be used (e.g., at least 95% must go to the defined project). Final eligibility depends on review by bond counsel and tax counsel.
