A competitive program designed to stimulate technological innovation by leveraging the small business sector's ability to meet federal research and development goals. It provides non-dilutive funds for early-stage green tech development across multiple agencies.
Similar to SBIR but mandates collaboration between small businesses and non-profit research institutions. This structure helps green energy startups access specialized academic expertise and facilities for R&D, fostering stronger commercialization pathways.
Provides large-scale loan guarantees for innovative energy projects that reduce greenhouse gas emissions and increase energy efficiency. While often associated with larger infrastructure, it has funded pioneering startups in carbon capture and advanced nuclear.
Not a direct government loan but a key partner in the USDA Rural Energy for America Program (REAP), this entity helps facilitate financing for agricultural and rural small businesses to adopt renewable energy systems.
Offers guaranteed loan financing and grant funding to agricultural producers and rural small businesses for renewable energy systems or energy efficiency improvements. It is a critical resource for agrivoltaics and bioenergy startups.
The NSF is the largest funder of SBIR/STTR awards, heavily supporting startups working on fundamental green technologies, including advanced materials for batteries, solar efficiency, and smart grid algorithms.
Promotes the use of biobased products and supports market development for bioenergy startups. It offers labeling programs and procurement preferences that help clean biomass companies gain commercial traction.
Various state-level agencies, such as New York State Energy Research and Development Authority, offer local loan products and incentives. These complement federal programs by addressing regional market needs and providing additional capital.
Supports university-based teams, often incubating startup technologies, in developing zero-energy homes. While not a direct startup loan, it provides significant R&D funding and validation for building-integrated PV startups.
While primarily for homeowners, these loans can finance energy efficiency upgrades and solar installations. Green energy startups offering retrofit services can leverage this federal guarantee to expand their customer base.
While technically a tax credit, the administration of transferability rules and direct payment options (for eligible entities) acts as a financial instrument that improves balance sheets for qualifying clean energy startups.
Provides funding to communities to assess and clean up contaminated sites, which can be developed for renewable energy projects like solar farms. Startups providing remediation or site assessment tech benefit indirectly.
Administered by the DOE, these grants go to state governments to implement their own energy efficiency and renewable energy programs. Startups can often access these through state-level vendor lists and partnerships.
For startups with international ambitions, the DFC provides loans and political risk insurance. This helps green tech companies deploy solutions in emerging markets where private capital is hesitant to enter.
California offers substantial state-level funding for clean tech startups, particularly in energy storage, hydrogen, and grid modernization. These grants often serve as seed funding that attracts private venture capital.
A public benefit corporation that leverages public money to attract private investment in clean energy projects. It offers innovative financial products like loan securitization and subordinated debt for innovative startups.
Provides grants and financing for companies working in clean energy technologies within Massachusetts. It offers a range of products including pilot project grants and commercialization funds for early-stage firms.
Includes provisions for electric vehicle charging infrastructure grants. Startups developing charging hardware or software can apply for federal funding to deploy networks, acting as revenue-generating assets.
While general, SBA loans can be secured through Community Development Financial Institutions (CDFIs) that specialize in green business lending. This pathway offers more favorable terms for sustainable startups.
Fosters public-private partnerships in advanced manufacturing, including green tech production. Startups can access NIST facilities and co-funding opportunities to scale manufacturing of solar cells or battery components.
