When you look for the next big leap in clean energy, you often find the answer in Israel. It is a nation constantly redefining what is possible in tech, and its energy innovators are proving that size is irrelevant to global impact. Whether it is transforming basic materials into industrial scale heat storage, radically redesigning the core of a battery, perfecting asset performance, or rethinking how buildings manage temperature, Israeli companies are delivering concrete solutions to the world’s climate crisis. Here are four standout firms demonstrating why this small ecosystem commands massive global attention.
Brenmiller Energy: Storing Heat in Stone
Brenmiller Energy has stepped in to solve the most critical roadblock for modern renewables: flexible, industrial scale storage. Instead of relying on traditional batteries or costly grid upgrades, Brenmiller developed a thermal energy storage solution that uses crushed rocks to store heat at extremely high temperatures.
This deceptively simple technology delivers clean, reliable energy on demand making it an elegant answer to the intermittency challenges of solar and wind. Brenmiller’s systems are already deployed across Europe, Africa, the US, and South America, supporting industries that need round the clock heat without the emissions. In a world searching for scalable decarbonisation tools, Brenmiller shows that the most groundbreaking solutions often come from reimagining nature’s most basic materials.

Addionics: Rethinking the Battery’s Blueprint
Instead of simply tweaking battery chemistry, Addionics is leading a revolution by attacking the problem from the inside out: reinventing the battery’s physical structure. While most companies aim to improve chemistry, Addionics focuses on reinventing battery architecture, specifically, the physical structure that determines how ions move through the cell.
Their patented 3D electrode design reduces resistance, improves energy density, increases cycle life, and speeds up charging, all without changing the chemistry. This means Addionics can integrate into existing manufacturing lines while delivering dramatically improved performance. For automakers, grid scale storage providers, and electronics firms, the implications are enormous: better batteries without the cost and disruption of rebuilding supply chains. Addionics is proving that a small structural shift can have a massive impact on how the world stores and uses energy.

Ensights: Turning Data into Peak Performance
Once the clean energy infrastructure is built, Ensights steps in to ensure those assets perform at their absolute financial and operational best. Their advanced optimisation platform collects, analyses, and interprets data from solar farms, batteries, and other clean energy systems to provide deep visibility into operational, financial, and maintenance indicators.
Ensights interprets trends, identifies inefficiencies, detects anomalies early, and recommends actions that maximise output and reduce costs. With renewable energy expanding rapidly across the globe, Ensights helps asset owners shift from reactive maintenance to predictive intelligence. By turning complex energy data into actionable insight, Ensights gives clean energy projects the opportunity to perform not just adequately, but exceptionally.

Oasix Energy: Smart Temperature Control for Buildings
Oasix Energy is quietly delivering a sophisticated solution that fundamentally improves how large buildings manage temperature and dramatically lower their energy use. Their advanced dual thermal storage technology captures and stores both heating and cooling simultaneously, across a huge temperature range from 50 degrees to 120 degrees
Unlike bulky, inefficient, or fire risk thermal systems of the past, Oasix delivers a compact, modular, and safe solution that reduces peak loads and dramatically lowers energy consumption. It is particularly powerful for data centres, commercial buildings, and industrial sites where both heat and cooling demands fluctuate throughout the day. Oasix’s innovation offers cities a pathway to net zero building standards that is both technologically sophisticated and operationally practical.
These four companies highlight a shared belief running through Israel’s clean tech sector: meaningful climate solutions must be not only innovative, but deployable, scalable, and grounded in real operational needs. From reshaping battery architecture to mastering thermal storage and making renewable energy more efficient, Israel’s energy innovators are charting a future where sustainability and performance go hand in hand.
