We invest in and commercialize early-stage advanced energy technologies that can provide venture-grade financial returns and reduce or mitigate at least 2.5 gigatons of GHGs between investment and 2050.

Investment Overview:

Beyond fulfilling our emissions-reduction mandate, each company must meet the additional five (5) criteria:

  1. Capital Efficient Commercialization: The company can reach pre-determined commercial milestones or be EBITDA-positive for less than $50M in total equity financing.
  2. Reasonable Valuation for Stage: The pre-money valuation is appropriate for the company’s current stage of technology development and is typically $5M to $10M.
  3. Team Seeks Hands-On Investors: The core team must be based in North America, assessed to be coachable, and committed to building a diverse, equitable and inclusive team that can effectively execute their business plan.
  4. Development Stage: The company’s product or service has a clear line-of-sight to initial commercialization within 24 months of our investment.
  5. Sustainable Market Advantage: IP protection or other sustainable competitive advantages provide a defensible position for the next 7+ years and/or can protect a gross margin of at least 40%.
Company Differentiator:

GHG Emissions-reduction Mandates: Every company we invest in must have the potential to mitigate 2.5 GT of GHG emissions by 2050. 

Clean Energy Expertise: Investing in cleantech since 2005 in more that 40 companies. We have 15+ venture partners from our sister investor syndicate, Clean Energy Venture Group. CEV’s advisory board is led by Secretary of Energy Ernest Moniz who is actively involved in the strategic guidance of CEV. 

Value-Add Resources: We are very active investors and bring a suite of resources to the early stage companies including leadership coaching/hiring with Dialogos, strategic marketing with CEV’s Director of Marketing, and deep technical team for multi-generational planning and IP development. 

Diversity, Equity and Inclusion (DEI): We believe in creating diverse teams and backing founders from underrepresented groups. Our term sheets for investment have detailed requirements for portfolio companies to implement and adhere to DEI policies and procedures.

Investment Example

In Q3 2020 CEV invested in SunDensity that has a solar glass coating technology that converts the blue light that cannot be absorbed by solar cells into red light that can be converted into electricity. Applied underneath the glass in solar panels, the photonic coating can increase panel efficiency by 20% or more. This is a highly disruptive innovation that will significantly reduce cost per watt of solar panels. Manufacturers apply this coating with widely available magnetron sputtering tools used throughout the glass industry, reducing engineering risk and helping the company grow “capital-light.” SunDensity’s technology has the potential to mitigate more than 2.5 gigatons of GHGs by 2050. The company was founded by Dr. Nishant Sonwalkar of MIT, who is leveraging a network of photonics experts across New York State. While the solar implications are expansive, this technology also has extended applications in consumer electronics and architectural glass.

Investments systematically target companies where social and/or environmental impact is integral to the product/service being created:

Our GHG emissions-reduction mandate is the clearest representation of where we invest in impact. We consider our emissions reduction criteria to be one of the most aggressive within our peer set and make it a gating item on beginning full due diligence. We clearly communicate this impact-orientation in our published articles, at events, in one-on-one conversations, and on our website. While we don’t expect our investments to eliminate racial or gender biases, we do consider ways their product or solution distinctly benefits underserved communities who will disproportionately feel the effects of climate change. This is a question in our application process that all companies must complete and integral to our screening.

Investments systematically include social and environmental sustainability practices in the due diligence process:

A standard condition of the term sheets that we issue is that companies agree to consider environmental, social, and governance (“ESG”) factors in its operations and report on such matters to us with metrics that include GHG footprint and GHG reduction. Given the early stage of the companies that we consider in our sourcing and due diligence policies, most companies are typically made up of ten or fewer employees at the time of investment and have not yet established many ESG policies. As active board members, we work with each portfolio company to establish ESG policies and best practices.
