Key takeaways: Natural gas turbochargers are specifically designed for natural gas engines. Natural gas turbochargers are optimized for high-altitude performance, crucial for markets like China. Natural gas turbochargers offer lower total operational costs and better compliance with emissions regulations.

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.

As fleets work towards reducing emissions, understanding the differences in aftertreatment systems for various fuel types is crucial. The adoption and growth of hydrogen internal combustion engines (ICE) is a significant step as hydrogen ICE provides a low-emission, low-carbon option for a more sustainable transportation sector. The mechanisms that clean exhaust gases in these engines are fundamentally the same as diesel ICE, with the key difference being what is in the exhaust gas to start with.

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.
