Clean Urban Energy

Clean Urban Energy, Inc. was a Chicago, Illinois cleantech company that turned large commercial office buildings into grid-scale thermal energy storage assets. Its technology harnessed the existing thermal mass of a building — concrete, drywall, furnishings — by pre-cooling during off-peak hours and coasting through peak demand, effectively operating the building as a multi-megawatt battery for demand response and load shifting without installing dedicated storage hardware. The company raised a reported $7 million venture round and appears in the Battery Ventures list of all portfolio companies. As of a July 2026 review the company has no live corporate web presence: the cleanurbanenergy.com domain no longer serves company content, and no developer portal, API, documentation, or GitHub organization could be located. It is catalogued here as an inactive, non-API-provider company record.

Clean Urban Energy is profiled on the APIs.io network. Tagged areas include Company, Energy, Cleantech, Energy Storage, and Thermal Energy Storage.
