Rondo Energy and Calgren Renewable Fuels start up 2MWh Rondo Heat Battery

In California, Rondo Energy and Calgren Renewable Fuels announced the start of commercial operation of a 2MWh Rondo Heat Battery (RHB) at Calgren’s facility in Pixley, California.

The Rondo Heat Battery captures intermittent renewable electricity, stores it at very high temperatures in brick materials, and delivers continuous industrial heat on demand. Calgren Renewable Fuels produces the world’s lowest CI ethanol, biodiesel, and renewable natural gas at their Pixley facility. Rondo is proud to be working with Calgren on this first step in further reducing both the cost of production and the carbon intensity of today’s biofuels. About half of the total carbon emissions of liquid biofuels comes from fossil fuel used in the refining processes. Rondo Heat Batteries eliminate these emissions by replacing fuel combustion with renewable electricity, dropping into existing facilities without process changes.

Without any process or feedstock changes, biofuels produced using clean Rondo heat and power double the CO2 savings per gallon.
