Given that we have a limited, accumulated budget for Green House Gas (GHG) emissions to keep global warming well below 2☌ (IPCC ref.: 1170 Gt CO2eq) or preferably 1.5☌ (IPCC ref.: 420 Gt CO2eq) compared to pre-industrial levels, ICE-based applications play a key role in reaching climate goals. Based on own calculations, we estimate the overall CO2 emissions of the off-highway market with Diesel engines >560kW to be approximately 690 Mt CO2eq in 2019 (following the SBT calculation methodvi ). (vi). Today’s off-highway market is dominated by fossil-fired ICEs which cause a significant amount of CO2 emissions.
Power Generation: ICE-driven generator sets for mission critical & backup power in hospitals, data centers, etc.The key applications of concern to Rolls-Royce Power Systems and this paper are: Nevertheless, it goes without saying that certain technology advances in the on-highway market were and will be transferred and innovated into the off-highway market and thus also into Power Systems products and applications. While many propulsion related discussions of today’s ICE are revolving around the high volumes of engines produced for the automotive industry, this paper addresses the future of the ICE through the lenses of our applications and industries. In recent years, the increasing focus on de-carbonization of the power train of on-highway applications has also reached many applications in the off-highway markets. In the most recent decades of ICE development, the main focus was on the increase of power density, on the performance map (aiming at optimizing fuel consumption at given load and speed profiles), on efficiency improvements and on emissions reduction.
