Terra produces a low-carbon cement alternative derived from abundant silicate rock that can replace up to 50% of Portland cement in standard concrete mixes. The product reportedly lowers carbon emissions by up to 70% and nitrogen oxide emissions by as much as 90% per ton of cement replaced, and is compatible with existing production processes. Terra is Golden, Colo.-based and has moved beyond lab scale to commercial deployment, breaking ground on a Cleburne, Texas plant in December that is expected to be the first U.S. commercial-scale facility of its kind. Its recent financing round, now $147 million in Series B funding after All Aboard’s $22 million coinvestment, is intended to help construct that plant. The company’s market positioning emphasizes ease of integration with current concrete production and significant emissions reductions versus conventional Portland cement.

Zanskar combines artificial intelligence, modern drilling techniques, and computational geoscience to find, assess, and develop geothermal energy resources. The company has a portfolio of greenfield geothermal projects, including the Lightning Dock site in New Mexico and recent discoveries at Pumpernickel and Big Blind in Nevada, plus two announced discovery sites in Nevada. Financially, Zanskar completed a $115 million Series C in January 2026 (later expanded with additional investment from Just Climate) and has now closed a $40 million revolving Development Capital Facility structured to scale to $100 million. Zanskar plans to use the new facility to fund pre-construction work and bridge projects to traditional project financing so it can rapidly build multiple geothermal power plants. The company aims to deliver gigawatts of clean, firm power to U.S. customers and expects to create hundreds of jobs as it scales development. Zanskar markets its approach as making geothermal more predictable, lowering development costs, and enabling large-scale deployment of dispatchable baseload power.
