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 to drive a turbine. The exhaust gas is still at about 600ºC. In a combined cycle gas plant, this heat can be used to produce steam that drives an additional turbine, adding…

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.

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 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.

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 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.

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.

Gas generation: what kind of bear is best?
This 20-page report compares combined cycle gas turbines (CCGTs), heavy-duty gas turbines, aeroderivative gas turbines, reciprocating engines and solid oxide fuel cells (SOFCs), on ten dimensions. No one gas generation technology is best. But modular solutions may increasingly rival CCGTs, especially for energizing AI data-centers?
