Rondo Energy builds heat batteries that store renewable electricity as high-temperature heat for industrial processes, decarbonizing hard-to-abate manufacturing.
Rondo Energy is a clean energy company founded in 2020 focused on industrial decarbonization through thermal energy storage. The company builds brick-based heat batteries that store cheap renewable electricity as high-temperature heat up to 1500 degrees Celsius, which can be delivered on demand as steam, hot air, or direct heat for industrial processes including cement, chemicals, food production, and paper manufacturing. Industrial heat represents roughly 20% of global carbon emissions and has been among the most difficult sectors to decarbonize because most industrial processes require consistent high-temperature heat that electricity alone cannot easily provide. Rondo's technology eliminates the need for fossil fuel combustion in industrial heating by storing excess renewable energy during low-cost periods and dispatching it as heat when needed. The company raised over $100M and has deployed commercial projects with major industrial customers including Linde and Siam Cement Group. Rondo Energy addresses a massive decarbonization opportunity that electrification and carbon capture alone cannot fully solve.
Grid capacity mapping platform for solar and storage developers pre-computing interconnection availability; $66M raised serving AES and Invenergy with 500+ GW analyzed across MISO, ERCOT, PJM markets.
Nira Energy is a Denver-based renewable energy software company providing grid capacity mapping and interconnection analysis tools that help solar, battery storage, and data center developers identify optimal project sites based on available grid capacity — reducing the years-long interconnection study process to minutes by pre-computing capacity availability across major US electricity markets. Backed by Y Combinator with $66 million raised, Nira generated $3.6 million in revenue in 2024, serving 100+ leading energy developers including AES, Invenergy, and Scout Energy with 500+ gigawatts of interconnection studies processed.
