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.

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.

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.

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…

Gas turbines and CHP: technology leaders?
This data-file profiles 30 leading companies in gas turbines and CHPs, from mega-caps such as GE, Siemens and Mitsubishi, down to small-caps and private companies with exciting new technologies. Case studies are also presented, with details on turbine installations.

Gas turbines: what outlook in energy transition?
Gas turbines should be considered a key workhorse for a cleaner and more efficient global energy system. Installations will double to 100GW pa in 2024-30, and reach 140GW in 2030, surpassing their prior peak from 2003. This 16-page report outlines four key drivers in our outlook for gas turbines, and their implications.

Turbo-charge gas turbines: the economics?
This data-file models the economics of turbo-charging gas turbines, which increases the mass flow of combustion air, to improve their power ratings by c10-20%. IRRs are solid. Turbo-charged gas turbines could thus gain greater share as grids become saturated with renewables

Gas turbines: what market size in energy transition?
CHP systems are 20-30% lower-carbon than gas turbines, as they capture waste heat. They are also increasingly economical to backstop renewables. Amidst uncertain policies, the market size for US CHPs could vary by a factor of 100x. We nevertheless find 30 companies well-placed in a $9trn global market.

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…
