Key Takeaways: Turbochargers for natural gas engines have evolved significantly, driven by stringent emissions regulations and the adoption of stoichiometric burning. Modern natural gas turbochargers feature distinct components compared to their diesel counterparts. Cummins’ innovations in natural gas turbocharger design have improved the cost-effectiveness and environmental performance of natural gas engines.

After working with Cummins Inc. and other major industry suppliers to slash emissions with a hydrogen internal combustion engine (H2-ICE), Southwest Research Institute is moving onto the next phase of its H2-ICE Consortium - drawing on real-world expertise from fleets.

Battery energy storage systems (BESS) are advanced energy storage solutions that store electrical energy for later use. They can be recharged when there is an excess supply of electricity, often at lower costs, or when intermittent renewable energy sources, such as solar or wind, are generating power. BESS can then discharge the stored energy to provide a dedicated power supply, support microgrids or supplement the general grid during periods of high demand or when electricity prices are elevated.

Knowing the fuel used for hydrogen fuel cells and hydrogen internal combustion engines (H2-ICE) is just as important as knowing the powertrains themselves. Fuel can impact not only performance but also a fleet’s green profile. Several terms are used to identify hydrogen and for various reasons. Dif
