## About

Avi Brenmiller, a former Babcock & Wilcox executive with decades in the thermal power sector, founded Brenmiller Energy in 2012 after recognizing that industrial heat — responsible for nearly a quarter of global energy consumption — lacked a viable storage solution. The company went public on the Tel Aviv Stock Exchange in 2019 and trades on the NASDAQ via an ADR listing, though its primary operations remain concentrated in Israel and Europe. Brenmiller Energy deploys its bGen thermal storage system, a modular unit that uses crushed volcanic rock as the storage medium. Customers include industrial facilities seeking to replace fossil-fuel boilers, utilities integrating concentrated solar power, and district heating networks. Notable projects include a 24 MWh installation at the University of Salerno in Italy and a collaboration with Siemens Gamesa for green hydrogen production. The company targets the global industrial heat market, estimated at over 1,500 TWh annually, prioritizing Europe and the Middle East. The firm has raised approximately $50M in equity and grants since inception, including a $10M grant from the Israel Innovation Authority and a 2022 funding round that included institutional investors. As of mid-2024, the company employs roughly 40 people, split between research and development in Rosh HaAyin and project execution teams in Europe. Brenmiller Energy has not disclosed a formal family office or asset management affiliate. Unlike most thermal storage startups that focus on grid-scale electricity storage, Brenmiller Energy's structural bet is on direct industrial heat replacement — a harder to decarbonize segment that still relies on coal and gas boilers. The bGen system's ability to reach 750°C and produce steam positions it for cement, chemicals, and food processing, markets where electrification remains uneconomical. This focus on industrial thermal storage rather than power markets differentiates Brenmiller Energy from peers like Malta or Energy Vault.

## Questions

### How does Brenmiller Energy's bGen system differ from battery storage?

The bGen system stores energy as heat in crushed volcanic rock rather than in electrochemical batteries. It can hold thermal energy at temperatures up to 750°C for hours at low loss, and release it as steam or hot air — matching the output of fossil-fuel boilers. Batteries are better for fast-responding grid applications; bGen targets the industrial sector where heat, not electricity, is the primary energy input.

### Which industrial sectors can use Brenmiller Energy's technology?

The bGen system is designed for heat-intensive industries including cement, chemicals, food and beverage processing, paper and pulp, and refining. A typical installation replaces 50–80% of a factory's natural gas or coal consumption for process heat. The company has publicly disclosed pilot projects with cement producers and district heating networks in Europe.

### What is the geographic focus of Brenmiller Energy's projects?

The company's primary market is Europe, driven by policy mandates for industrial decarbonization and high natural gas prices. Key project locations include Italy (University of Salerno), Spain (with Siemens Gamesa), and Israel. The firm has stated interest in the Middle East and North Africa for solar thermal integration but has not disclosed active projects there as of mid-2024.
