Cleantech Open is the world’s largest cleantech accelerator, providing entrepreneurs and corporate innovators the resources they need to launch and grow successful cleantech businesses. Our one-of-a-kind innovation ecosystem built over the last 19 years of programming spans key cleantech innovation hubs in the U.S., linking labs and universities, service providers, investors, corporations, governments, and other cleantech incubators and accelerators. Through our annual accelerator, we provide between 100-150 companies in the U.S. with a rich program of customer discovery, extensive mentoring, training, investor meetings, startup-corporate matching, and showcasing at both the regional and national levels. Since 2005, more than 70% of our reporting U.S. alumni companies are still operating and have collectively raised over $3B in external funding. Join this exciting community and be a part of our global network of innovation.

EPA’s Office of Brownfields and Land Revitalization is announcing the availability of $20 million dollars to award approximately 20 cooperative agreements for the Multipurpose Grant Program. Multipurpose Grants provide funding to carry out a range of eligible assessment and cleanup activities, including planning and additional community engagement activities. Applicants may request up to $1,000,000 to address hazardous substances and/or petroleum contamination at one or more brownfield sites. Activities carried out at each approved, eligible site may exceed $200,000.

The goal of the Design for Environmental Sustainability in Computing (DESC) program is to address the substantial environmental impacts that computing has through its entire lifecycle from design and manufacturing, through deployment into operation, and finally into reuse, recycling, and disposal. These impacts go well beyond commonly-considered measures of energy consumption at run-time and include greenhouse warming gas emissions (GHGs), depletion of scarce resources like rare earth elements, and the creation of toxic byproducts.

Mark1 is a Developer-as-a-Service for capital intensive, first of a kind industrial climate technologies. We work with technology companies to maximize the opportunity for deploying their first commercial-scale projects. Mark1 helps climate tech innovators develop a faster and less expensive path to bankability. With an experienced in-house team, we co-pilot the process alongside project-specific needs of each participating company, to achieve the project’s development milestones. We support technical and commercial project development and capital strategies.

We provide capital, expertise, and connections to nurture startups specializing in advanced energy systems, industry efficiency technologies, and sustainable solutions. Our particular emphasis is on closed-loop lithium systems, next-gen battery development and supply chain innovations, leveraging Nevada’s unique position in the global energy market. The accelerator aims to develop these innovative startups into thriving enterprises that deliver both economic growth and positive environmental impact.

Be part of the Energy Tech 2025 Conference at the SPARK VIRGINIA Pitch Competition, where Virginia’s most innovative minds in utility, energy, and climate technology compete for $10,000 in prizes ($7,500 grand prize winner; $2,500 runner up)! Taking place on March 6, 2025, at the Science Museum of Virginia during Energy Tech 2025 in Richmond, this exciting event will showcase groundbreaking technologies poised to transform Virginia’s energy economy. Eight startups will pitch their cutting-edge solutions to a panel of Virginia’s top investors, utility executives, and energy leaders. With only five minutes to present and five minutes for Q&A, these entrepreneurs will compete for funding, recognition, and the opportunity to accelerate their journey to commercialization.

The Catalyst Program provides grants of up to $75,000 to researchers and early-stage companies looking to demonstrate initial prototypes of their climate technologies. Catalyst is jointly administered by MassCEC and MassVentures with a goal of stimulating the commercialization of climate technologies developed in the Commonwealth. Specifically, the program is designed to demonstrate the feasibility of transforming new ideas from the research stage to commercially viable technologies to increase industry and investor interest. All awardees gain access to a vast network of partners, expert local market and policy insights, and mentoring from MassCEC and MassVentures, while all finalists receive complimentary pitch coaching and business mentoring.

Circular supply chains improve security and reduce environmental impacts, maximizing the lifetime of materials and products in the economy to support a robust and competitive manufacturing sector while providing economy-wide environmental benefits. Research and development (R&D) of new technologies to increase reuse, repair, recycling, remanufacturing, and repurposing of products and
materials will be essential to realize these economic and environmental benefits. To maximize effectiveness, R&D must be informed by analysis of non-technical factors, including market forces, business models, and the policy landscape. Such analysis can provide a systems-level view–identifying promising technologies and deployment pathways as well as what roadblocks remain–especially when it leverages input from a wide set of connected stakeholders. Those stakeholders can also amplify the impact of DOE investments in technologies that advance circular supply chains. This Notice of Funding Opportunity (NOFO) seeks to assemble a team that will conduct analysis, connect broad groups of stakeholders within multiple application spaces, and socialize EERE-developed innovations across a variety of industries to advance those innovations. The Accelerator’s role will include advancing the entire circularity field’s understanding of emerging technologies, thereby enabling the identification of potential roadblocks to deployment and opportunities to reduce the risks of technology commercialization.

The program will bring together entrepreneurs from across the U.S. and the globe, empowering them to address climate mitigation, adaptation, and resilience.
