DNV has unveiled an updated version of its computational fluid dynamics (CFD) software, KFX, developed through joint industry projects with major energy companies. The software's new features focus on specialized consequence modeling of carbon dioxide (CO2), ammonia (NH3), and hydrogen (H2), crucial for the safe implementation of energy transition solutions like carbon capture, utilization and storage (CCUS). These enhancements allow for accurate simulations of gas dispersion, fire, and explosions, aiding in the design of installations and quantitative risk assessments. The release of KFX showcases DNV's commitment to collaboration with leading energy firms to decode the complexities of the energy transition. Industry partners like Equinor and TotalEnergies have collaborated closely with DNV over the past four years to develop these unique capabilities reflecting the physical properties of each fluid. The software now predicts phenomena like the formation of dry ice from CO2 releases and the sublimation of particles, benefiting cost-efficient decarbonization projects. Moreover, the software includes a multi-component spray model to simulate ammonia gas absorption in water droplets, aiding in evaluating safety measures for accidental releases. Extensive testing and validation have been conducted for hydrogen dispersion, combustion, and radiation models within KFX, with enhancements made to the gas explosion solver for better prediction of hydrogen explosion effects. DNV's Head of Section of CFD Solutions, Trond Evanger, highlights the software's ability to create more accurate models, leading to improved decision-making in critical energy projects. The article emphasizes that these advancements support the safe and effective deployment of CCUS, hydrogen, and ammonia technologies, ultimately optimizing safety measures and design efficiency in energy transition initiatives. The release of the latest version of KFX represents a continuation of DNV's three-decade commitment to providing cutting-edge CFD solutions in collaboration with industry leaders.
