Energy and AI: the power and the glory?
…6% of a data-center’s energy needs could be self-powered via on-site solar, per pages 8-9. Combined cycle gas turbines are predicted to emerge as a leading energy source to meet…
Fuel cells: performance, efficiency and decline rates?
…efficiency of 46%. This is above the electrical efficiency of coal plants which average 38%. Simple cycle gas turbines achieve 40%, rising to 57% for the average combined cycle plant…
Pressure ratings: industrial and energy processes?
…LNG plants. Higher pressure industrial processes will reach around 200-bar, for example in the turbine inlet temperature of a gas turbine, or in an ammonia plant. One conclusion is that…
Power plants: average capacity?
…92MW and 84MW respectively, and interquartile ranges of 8-160MW and 5-144MW. However, a c100MW gas turbine lives in a warehouse near its customers, while a 100MW wind farm covers 10,000…
Leading companies in super-alloys?
…also aggregated data into the recipients of ARPA funding to develop super-alloys for next-gen gas turbines, which will boost maximum turbine inlet temperatures from 1,600C to 1,800C, which would improve…
Land intensity of energy transition: acres per MW and per ton?
…emerging nations as part of a just transition. The least land-intensive power generation source is gas turbines, which require 0.2 acres per MW, followed by nuclear and coal plants at…
Prime movers: efficiency of power generation over time?
…rising to around 10% by the 1900s, to 30-50% at modern coal-fired power generation using pulverised, then critical, super-critical and ultra-critical steam. The first functioning gas turbines were constructed in…
Mainspring Energy: linear generator breakthrough?
…to the blades and precision-engineered compression and turbine stages within a gas turbine. Higher efficiency can also be unlocked by harnessing the expansion of combustion gases directly, rather than having…
Global electricity: by source, by use, by region?
…150bcfd in 2023 to 385bcfd by 2050, which also boosts demand for gas turbines. Fuel use for coal, gas and oil, by region, and over time, are broken out on…
Boltzmann energy overview?
…x volume (in m3) = number of molecules x absolute temperature (in Kelvin) x the Boltzmann constant (in Joules/Kelvin). We find ourselves using these physics when modelling gas turbines, compressors,…
