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.
Houston oilfield completions and drilling (NYSE: HAL) $22.9B FY2024 revenue; #1 US hydraulic fracturing, Zeus E-frac, international expansion, $4.0B adj. operating income competing with SLB and Baker Hughes.
Halliburton Company is a Houston, Texas-based oilfield services company — publicly traded on the New York Stock Exchange (NYSE: HAL) as an S&P 500 Energy component — providing products and services for the exploration, development, and production of oil and natural gas through two segments: Completion and Production (hydraulic fracturing, cementing, artificial lift, wireline logging) and Drilling and Evaluation (drill bits, directional drilling, formation evaluation, well construction planning) through approximately 50,000 employees in 70+ countries. In fiscal year 2024, Halliburton reported revenues of $22.9 billion and adjusted operating income of $4.0 billion, with North America (the most important market — driven by US shale completions) generating $8.6 billion and international operations (Middle East, Latin America, Africa, Europe) generating $14.3 billion. CEO Jeff Miller has led Halliburton's return to strong profitability following the COVID-19 oil demand collapse with a disciplined capital-light model: rather than owning all completion equipment (pressure pumping fleets, cementing units), Halliburton has entered long-term customer partnerships where major E&P operators (Pioneer, EOG, Devon, ConocoPhillips) commit multi-year completion work to Halliburton in exchange for deployment priority and dedicated crew relationships — reducing equipment idle time and Halliburton's capital requirements while securing predictable activity levels. Halliburton's Zeus electric fracturing fleet (E-frac using natural gas-powered electric motors to drive frac pumps rather than diesel engines) reduces NOx emissions and fuel cost for US shale operators — achieving 40-50% fuel cost reduction that operators increasingly specify as a sustainability requirement.
