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.

Is electrification the only decarbonization option for the bus and coach industry right now? That’s a key question that will no doubt be asked at the National Bus & Coach Show at Brisbane’s Exhibition Centre from September 17-18 as the optimism and uncertainties of the future collide with the realities of the moment. While battery electric vehicles may eventually dominate the landscape, the current limitations of vehicle cost, range and supporting infrastructure still need to be addressed.

Cummins Inc.'s Australian-made PGXL coolants are widely accepted in the mining industry, providing superior protection across all diesel engine brands. In supporting remote mine operations, Cummins provides a well-established bulk coolant delivery service, eliminating the need for miners to manage their coolant inventory. Cummins takes care of all the logistics, delivering the coolant directly to the minesite. The PGXL production facility in Melbourne has the capacity to deliver 30 million litres of coolant per annum, so supply is readily available.

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.
