The Problem

New York City ranks third in the world for cities with the largest carbon footprint per capita, according to a 2018 report by the Norwegian University of Science and Technology. The NYC Mayor's Office of Sustainability notes that, while the bulk of greenhouse gas (GHG) emissions in most U.S. cities is caused by transportation, 68% of New York's emissions come from buildings.

The passage of New York City Local Law 97 (LL97) is meant to help the city substantially reduce its CO2 emissions for buildings that are 25,000 square feet or larger by creating carbon caps. This poses a challenge to building owners, who face fines for noncompliance. The average owner is anticipated to owe $100,000 in fines annually. New York state is developing similar regulations as part of its Climate Leadership and Community Protection Act (CLCPA).

Our Solution

VanChargTM is a Vanadium Redox Flow Battery which charges from electrical sources like wind, solar, or the electrical grid, and discharges power as needed to support a building's energy load.

Owners of multi-family residential, commercial office, and small industrial buildings are best suited to use our rechargeable battery and energy distribution services, which stores energy during off-peak times and uses the stored power at peak times, to reduce their greenhouse gas emissions and cut down on utility bills.
