…by absorbing cheap renewables and running the gas turbines less frequently? Returning to our ethane cracker example above, we estimate that each ton of ethane requires 24mcf of gas (around…
…makes for a fascinating case study into how gas turbines are used to stabilize power grids, backstop renewables, and how this has changed over time. $799.00 – Purchase Checkout Added to cart…
…solar, per pages 2-4. Hence, we have drawn five conclusions about the utilization rates of gas turbines, generation in MWH and capacity requirements in MW on pages 5-9 of the…
…flow by $5/kW/year. Numbers can be stress-tested in the data-file. Other inputs in the model are informed by our data into gas turbine parameters, gas turbine capex costs, gas prices…
Combined heat and power systems are 20-30% lower-carbon than today’s gas turbines, as they capture waste heat. They are also increasingly economical to backstop renewable-heavy grids. Amidst uncertain policies, the…
…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!…
…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…
This data-file explores an alternative design for a combined cycle gas turbine, re-circulating exhaust gases (including CO2) after the combustion stage, back into the turbine’s compressor and combustion zones. The…
…Cycles are always going to ‘beat’ Rankine Cycles. As a rule of thumb, gas turbines are going to be 1.5x more efficient than steam turbines. But they are also harder…
…simple cycle gas turbines only achieve c40%. The theme and opportunity are therefore explored in our 17-page note below. https://thundersaidenergy.com/2020/09/17/a-new-case-for-gas-what-if-renewables-get-overbuilt/ (4) Over-building electric vehicles? Subsidies for EVs are also more…
