Our Mission

Allotrope Partners mission is to accelerate and capitalize on the transition to a sustainable energy future.

Our role is to identify and develop companies and projects in the clean economy, help deploy pools of capital into those opportunities, and educate decision-makers on successful policy and investment paradigms. Allotrope’s investments span both developed and emerging markets, where ongoing policy, resource and technology shifts are generating higher returns, lower risk and simplified execution.

The Allotrope model is ultimately focused on identifying physical asset opportunities that generate both conventional outputs and environmental benefits. These opportunities can be either discrete projects or project development platforms that spin off multiple assets.  Allotrope focuses on incubating projects in-house but also seeks opportunities to be a “developer of developers,” where we match the right capabilities with the right set of projects.


What We Do

Project Development

Project Development and Finance

We incubate projects in-house and make active operational investments in low carbon project developers with new approaches to markets, products, and services.

Strategic Development

Strategic Investments

We make a select number of small early stage investments in technologies and business processes that are on a trajectory that complements our asset-based development and project-financing model.



We deliver high value advisory capabilities in areas directly related to our mission. This allows us to participate actively in the public dialogue about paths to the clean economy and stay informed on critical developments both domestically and globally.

  • Environmental Matters – Through the Looking Glass in Lebanon 06/27 -

    Did I say Lebanon? Isn’t that a country at war? Isn’t that a country where environmental concerns are but a distant priority to fundamental governance issues?

    Well, as was reinforced to me over the last week of travel there, you might be technically right in asking those questions, but fundamentally wrong. But we’re biased. My partners have never shied from challenging geographies, and we have a significant investment interest in a Middle East group called V4Advisors, which provides technology and consulting services for companies and development agencies to account for environmental impacts. For as it turns out, companies operating in ...Read More

  • California Dreaming? 05/27 -

    “Dreaming” seems to be a theme espoused by pundits in the blogosphere who follow environmental markets, and by the various research analysts who have dipped their toes in the subject over the years. But in California, the dream has been colliding with reality for a number of years. Even though Allotrope is fundamentally focused on developing, acquiring and managing assets, we follow the pricing and policy fundamentals in the markets for renewable energy credits, low carbon fuel certificates, water programs, and carbon. In these areas, California isn’t dreaming at all. And since virtually all of us at Allotrope owe large ...Read More

  • Biomass – In a World of Black and White, I’ll Take Gray 05/09 -

    A couple of recent news items on biomass energy have forced us to do some thinking. Is biomass energy really worse than coal? That seems unlikely, but some folks, like the Partnership for Policy Integrity, don’t like it one bit. And there are broader coalitions arguing against EU biomass subsidies in general. And that coalition includes some friends of ours… (Dan K, let’s have lunch soon.)

    On the other hand a significant industry has grown around the sector and real advocacy groups promote the biomass energy sector. But it seems to us that ...Read More
