Fast-charge the electric vehicles with gas?
When electric vehicles are widespread, how will we fuel them? Our model shows the economics can be compelling for powering fast-chargers using gas turbines. $289.00 – Purchase Checkout Added to cart The…
Thermodynamics of prime movers: energy from first principles?
…high-grade gas turbines. Muscle power was the original prime mover in the pre-industrial energy system (chart below). But a typical horse outputs 0.75 kW of power, converts only c10-30% of…
Adiabatic flame temperature: hydrogen, methane and oil products?
…blessing in terms of thermodynamic efficiency. But conversely, the limit on pre-existing gas turbines is not the ability to generate high flame temperatures. It is the ability to withstand them!…
LNG liquefaction technologies: an overview?
…What compressor turbines are used in LNG plants? First generation plants used steam turbines. Second generation plants used industrial gas turbines. Recent plants use aero-derivative turbines, which have smaller footprints,…
