Gas turbines: operating parameters?
A typical simple-cycle gas turbine is sized at 200MW, and achieves 38% efficiency, as super-heated gases at 1,250ºC temperature and 100-bar pressure expand and drive a turbine. Efficiency rises to 58% in a combined cycle. The purpose of this data-file is to tabulate typical operating parameters of gas turbines.

Coal-to-gas switching: what CO2 abatement cost?
Coal-to-gas switching halves the CO2 emissions per unit of primary energy. This data-file estimates the CO2 abatement costs. Gas is often more expensive than coal. But as a rule of thumb, a $30-60/ton CO2 price makes $6-8/mcf gas competitive with $60-80/ton coal. CO2 abatement costs are materially lower in the US and after reflecting efficiency.…

Gas power: levelized costs of combined cycle gas turbines?
Levelized costs of combined cycle gas turbines are built up in this data-file. Our base case costs of gas-fired power generation are 8c/kWh, at a combined cycle turbine converting 55% of the thermal energy of natural gas into electrical energy, for a total CO2 intensity of 0.35 kg/kWh.

Global gas turbines by region and over time?
Global gas turbine additions averaged 50 GW pa over the decade from 2015-2024, of which the US was 20%, Europe was 10%, Asia was 50%, LatAm was 10% and Africa was 10%. Yet global gas turbine additions could double to 100 GW pa in 2025-30. This data-file estimates global gas turbine capacity by region and…

Renewables+gas LCOEs versus standalone gas turbines?
Levelized costs of electricity depend as much on the system being electrified as the energy sources used to electrify it. This data-file captures solar+gas LCOEs (in c/kWh), when meeting different load profiles, as a function of solar capex (in $/kW), gas prices (in $/mcf), and the relative utilization of solar vs gas.

Methane slip: how much gas evades combustion?
Methane slip occurs when a small portion of natural gas fails to combust, and instead escapes into the atmosphere. This data-file reviews different technical papers. Methane slip is effectively nil at gas turbines and gas heating (less than 0.1%). It rises to 0.5-3% in cookstoves and some dual-fuel marine engines. However, the highest rate of…

Thermal power plant: loss attribution?
This data-file is a simple loss attribution for a thermal power plant. For example, a typical coal-fired power plant might achieve a primary efficiency of 38%, converting thermal energy in coal into electrical energy. Our loss attribution covers the other 62% using simple physics and industry average data-points.
