Pratt & Whitney Unveils Details Of Hydrogen-Steam Hybrid Engine Cycle
Description
Pratt & Whitney is exploring hydrogen fuel for zero carbon emissions with its Hydrogen Steam-Injected, Intercooled Turbine Engine (HySIITE). The concept, developed under a $3.8 million ARPA-E project, combines cryogenic fuel properties with steam injection for efficiency. Early results show potential for up to 35% lower energy use compared to current engines, though further study is needed.

Avnos' Hybrid Direct Air Capture: The Future of Carbon Removal and Water Production
Avnos is revolutionizing carbon removal with its Hybrid Direct Air Capture (HDAC) technology, which simultaneously captures CO2 and water, producing distilled-quality water as a byproduct. The technology is more energy-efficient and cost-effective than traditional systems, with Avnos aiming to reduce removal costs to under $100 per ton. The company is rapidly expanding, with projects in California and New Jersey, and is positioned to lead in both carbon capture and water-positive solutions.

Carbon-Neutral Calcium Carbonate Process Uses Emissions From Steel-Making Plant
A carbon-capture project at U.S. Steel’s Gary, Indiana plant will convert CO2 emissions into carbon-neutral calcium carbonate (endurocal®). The process, developed by CarbonFree, uses flue gas and slag to create high-purity calcium carbonate for various applications. Endurocal® offers the same properties as conventional products but with a zero carbon footprint and lower cost.
