Fortlev and Brenmiller Energy Inaugurate the World’s First Renewable Energy-Powered Thermal Energy Storage System for Plastic Manufacturing – AltEnergyMag


-Brenmiller Energy’s bGen Technology Uses Biomass to Heat Crushed Rocks to More Than 600° Celsius, Enabling the On-Demand Delivery of Hot Air to Fortlev’s Polyethylene Water Tank Molding Machines
-bGen Thermal Energy Storage Unit Allows Fortlev to Reduce Fuel Costs by More than 75% and Greenhouse Gas Emissions By 800 tons of CO2 per year

Brenmiller Energy, a global leader in thermal energy storage, announced today that it and Fortlev, the largest producer of water storage solutions in Brazil, have inaugurated a bGen Thermal Energy Storage (TES) unit at Fortlev’s production facility in Anápolis, Brazil.

The bGen unit is the first TES system powered by renewable energy to be used to generate hot air for manufacturing plastic products in the world and also the first thermal energy storage system powered by renewable energy to be used for commercial operations in South America.

The 1 MWh bGen unit enables Fortlev to use renewable biomass rather than natural gas to heat the air it uses to make plastic water tanks with rotational molding machines. Substituting biomass for natural gas allows Fortlev to lower the fuel costs associated with heating this air by more than 75%. Use of the bGen unit will also lower the greenhouse gas (GHG) emissions associated with heating this air by approximately 800 metric tons per year.

Fortlev and Brenmiller Energy are in discussions to install 60 bGen units at the facility, which will enable it to avoid 48,000 metric tons of GHG emissions per year – an amount equivalent to the GHG emissions released by approximately 10,500 gasoline-powered passenger vehicles driven for one year.

“Fortlev is dedicated to delivering its customers high-quality, competitively priced water storage solutions while respecting the environment,” said Antonio Torres, Fortlev Solar CEO. “By helping Fortlev lower our fuel expenses and decarbonize one of our thermal manufacturing processes, Brenmiller Energy’s bGen technology is helping us realize this goal and do well while doing good.”

Having demonstrated the financial and environmental success of bGen’s TES technology, over the next few years Fortlev might not just expand its use of bGen at its Anápolis production facility, but also at its seven other manufacturing facilities in Brazil.

In addition, Fortlev Solar, as a partner of Brenmiller Energy in Brazil, is intending to open a manufacturing factory to produce bGen units for the Brazilian market.

Storing Renewable Energy as Heat to Produce Steam, Hot Water, and Hot Air

Many industrial companies have found it difficult to economically decarbonize plastic roto-molding, food preparation, chemical production, pulp and paper manufacturing, and other thermal processes that require the production or use of steam, hot water or hot air. For example, battery-based energy storage technologies do not efficiently store renewable energy for hours to days at a time, nor do they efficiently convert this energy on-demand into the heat needed to produce steam, hot water, or hot air.

By combining thermal storage, heat exchange, and steam generation together in a single solution, Brenmiller Energy’s bGen technology can provide industrial companies with the energy efficiency, output stability, scalability, and other capabilities they need to cost-competitively decarbonize their thermal processes. Brenmiller Energy’s technology is also flexible, enabling companies to use both electricity (from solar panels, wind turbines, and the grid) and thermal sources of energy (biomass, flue gas, recovered heat) to charge the bGen units.

The crushed rocks in the bGen units can efficiently store this energy as heat for minutes, hours, or even days. Then, when companies need it, they can use this heat to …….
