Well looking at the advertorial for Cummins and the future of Diesel I think Cummins can't not be further from the truth.
Cummins state
Diesel power delivers better acceleration, forklift speed, and driveline torque at low RPM, as well as easily handling any hydraulic additions. A electric forklift will accelerate better than a Diesel truck over a short length. A 100% Zero emission ammonia hybrid using an electric drive will out perfume any diesel truck.
Less maintenance issues. A diesel forklift requires less scheduled repair and maintenance. Electric trucks and ammonia hybrid have less moving parts than a diesel Torque converter truck and require around 50% less maintenance.
More cost efficient. The cost of diesel is usually less than propane and diesel lifts feature a lower cost of ownership than propane. An Ammonia hybrid truck is more efficient and cost less to run than a diesel forklift. A 10,000kg Diesel forklift would cost around 9.6 US dollars to run per hour. A 10,000kg Ammonia hybrid cost around 4 US dollars per hour to run
