Incubating Market-Propelled Entrepreneurial-Mindset at the Labs and Beyond

IMPEL is a Department of Energy tech-to-market program focused on building technologies, funded by the Building Technologies Office and implemented by Lawrence Berkeley National Laboratory.

Our program helps early-stage individuals from business, academia, and DOE’s national labs translate the premise and promise of their technology into the language of business, boosting their chances of bringing it to market. These individuals–or as we call them, IMPEL Innovators–have a passion for the building lifecycle (design, construction, operations, and circular technologies) and for energy technologies that integrate with buildings (onsite renewables or grid integration incorporating electrification, energy storage, and electric vehicle charging). The buildings sector has been notoriously challenging for bringing tech-to-market, where many new projects or businesses fall victim to the notorious ‘valleys of death’.

IMPEL has a strong theory of change: Support technology commercialization for net zero built infrastructure, that promotes equitable wellness and resilience for all.

Our Innovators have technologies that fall across three focus areas:

Hear IMPEL Program Director Reshma Singh talk about the IMPEL engine that accelerates climate tech in buildings and energy by recruiting and fostering a dynamic Innovator community, mentoring them to develop strong entrepreneurial skill sets, and enabling access to powerful public and private tech-to-market pipelines.

IMPEL provides Foundational Training and Pipeline Opportunities

Through the program, Innovators receive access to IMPEL's Foundational Training, including:

While acceptance into the program guarantees participation in our foundational training, a select number of Innovators will also be offered exclusive opportunities for further training through our Business Seminars and other pipeline opportunities with our partners at the U.S. Department of Energy and Greentown Labs.

Visit the IMPEL Timeline page for more information about each of these pillars of IMPEL programming.

IMPEL Connects Innovators to Experts

The IMPEL Executive Team at Lawrence Berkeley National Lab supports Innovators' journeys through every step of the program, while connecting them to Expert Coaches, Incubators, Mentors, and a wider network within the building technology space. 

Read more below about the types of experts that IMPEL offers.

Expert Coaches

IMPEL Coaches provide dynamic guidance during the one-day workshops to help Innovators refine and practice verbal pitches to communicate their technology or idea clearly, succinctly, and compellingly to critical stakeholders. Our coaches are field experts: skilled entrepreneurs who have raised multi-million dollar funds, judged startup pitches, coached technologists towards successful commercialization.

Meet our Coaches


IMPEL has partnered with Greentown Labs to provide real pitching opportunities and connections to a broader pool of mentors, investors, and other innovators in climate-tech. They help Innovators engage with the private sector, gain fully-funded access to national pitch events, and accelerators. 

Learn more about our Partners


IMPEL Mentors represent investors from boutique and impact funds to financial giants, potential demonstration partners from major universities, state energy offices, and federal entities including the General Services Administration and the Department of Defense, major corporate ventures, and subject matter experts from national labs.
