Electrified Thermal Solutions' Joule Hive™ Thermal Battery Achieves Technology Readiness Level 6, Meeting Key DOE Performance Milestone - Selected for over $40M in Department of Energy Funding

Trending...
BOSTON, Aug. 5, 2024 ~ Boston-based company, Electrified Thermal Solutions (ETS), has received a significant funding extension from the U.S. Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E). The company, known for its innovative thermal energy storage solutions, has successfully completed the final milestones required for this funding by cycling its E-Brick heated circuit to a temperature of 1,700°C (3,092°F) in ambient air operating conditions.

This achievement marks a major milestone for ETS' Joule Hive Thermal Battery (JHTB), which has now reached a Technology Readiness Level (TRL) 6. By blowing air across the bricks' surface, the JHTB demonstrated its ability to deliver heat to industrial processes. This success has enabled ETS to secure a $5 million award from the DOE Industrial Efficiency and Decarbonization Office and a $35 million award from the DOE Office of Clean Energy Demonstrations.

With these funds, ETS expects to achieve TRL 8 by 2025 with a megawatt-scale commercial demonstration of their Joule Hive Thermal Battery. This will allow them to decarbonize the heat processes of their industrial partners in sectors such as cement, chemicals, food and beverage, and consumer goods manufacturing.

The need for decarbonization in heavy industry is becoming increasingly urgent as carbon emissions from power generation and transportation continue to decrease while emissions from heavy industry continue to rise. In fact, industrial heat processes are responsible for approximately 20% of global greenhouse gas emissions. Currently, most industrial heat demand is met by burning fossil fuels, particularly natural gas. However, ETS has developed an alternative solution that is both cost-competitive and zero-carbon.

The JHTB can harness clean energy-derived electricity to generate, store, and deliver zero-carbon heat even at extremely high temperatures. Developed over almost a decade at MIT, this technology provides the lowest-cost decarbonized heat by using onsite renewable electricity or charging from the grid during off-peak hours when electricity is the least expensive.

The JHTB is the first thermal energy storage system to durably deliver up to 1,800°C (3,275°F) heat from electricity, making it suitable for even the most demanding industrial applications. This achievement is a key milestone towards commercialization and aligns with the vision jointly set out by ETS and ARPA-E.

According to Daniel Stack, Co-founder and CEO of Electrified Thermal Solutions, "We are quickly knocking down the barriers to electrifying high-temperature heat processes for industry." He explains that historically, the inability of state-of-the-art heating elements to survive at the highest temperatures required for heavy industry has been a major obstacle. However, ETS has found a solution by slightly altering the composition of traditional firebrick.

Dr. Peter de Bock, Program Director at ARPA-E, also recognizes the significance of this milestone. "This marks an important step in opening the door to decarbonization of industrial heat processes around the world," he says. The breakthrough was achieved as part of ETS' milestones from an ARPA-E SEED award in 2021, and this latest funding will support their efforts towards commercialization.

With this successful milestone under their belt, ETS is now focused on building a 1MW, 5MWh JHTB commercial demonstration system that will be operational in 2025. They plan to follow this with first-of-a-kind deployments at customer sites in support of their goal to deliver 2GWs of thermal power capacity by 2030. This aligns with their mission to decarbonize heavy industry with electrified heat.
