Rolls-Royce Solutions released after comprehensive field and testbench testings around 80% the active portfolio for paraffinic fuels inherent to EN15940. This affects internal combustion engines for the power generation, marine, mining, rail and construction industry as well as agricultural industry. The fuel norm considers drop-in solutions combinable with fossil fuel and besides the lower density, paraffinic fuels reveal higher heating value and cetane number supplemented by longer shelf life, no impurities, and a high cold resistance. The testing focus within this norm was on Hydrotreated Vegetable Oil (HVO) caused by the most efficiency in savings in greenhouse gas emissions up to 90%. The releases enable Rolls-Royce Solutions to actively participate in the energy transition because avoidance and reduction of greenhouse gas emissions are key to stay qualified for business relationships, enter new markets and stay attractive for institutional investors. To spread the word of the sustainable utilization of internal combustion engines within the heavy-duty-industry and shape the market landscape proactively Rolls-Royce Solutions and Neste closed end of 2022 a strategic partnership. To combine best available renewable fuel quality by Neste with best available internal combustion engine performance, Rolls-Royce Solutions performed testing’s resulting in a decrease in NOx (−16%), CO₂ (up to 90%), and PM (up to 80%), improved response to load acceptance, full power performance and similar fuel consumption. From this reveal, a renewable paraffinic fuel prolongs the life cycle of internal combustion engines to enable customers a feasible economic operation by reaching strategic sustainability targets.
