GENCELL G5rxUtility Backup Power Solution



Aging electrical grids and more frequent extreme weather make it increasingly challenging to meet the power needs of always-connected businesses and consumer lifestyles. In 2015, Americans experienced a reported 3,571 total outages, with an average duration of 49 minutes. Momentary blackouts cost the US economy $60 billion while sustained blackouts cost $50 billion.

Keeping Auto-Reclosers Operational

The GenCell G5rx utility backup power solution produces 5kW of emissions-free electricity for substations during power outages. Operating as a direct source of power or supplementing legacy backup battery systems that provide only 6-8 hours of electricity, the GenCell G5rx keeps circuit breaker auto-reclosers operational until the grid recovers. The solution alleviates the need for costly multiple battery rooms, avoids the pollution and maintenance costs of diesel and includes a shelter that is resistant to high-voltage interference and earthquakes.


What Powers the G5rx?

The G5rx is powered by hydrogen. GenCell has developed a number of patented technologies to reduce the capex and opex of our fuel-cell power solutions, including the use of a non-platinum catalyst, mechanisms for using ambient air as an oxidizer, and using lower-cost fuels such as industrial-grade hydrogen gas. These technology breakthroughs overcome the obstacles that have historically prevented the mainstream adoption of fuel cells.
