…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…
…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…
This data-file aggregates information into the strength, temperature resistance, rigidity, costs and CO2 intensities of important structural metals and materials. It shows why nickel-based super-alloys are used in gas turbines…
…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…
…for CO2 trucking or CO2 shipping). But there are some unexpected spikes in the heat capacity ratio in the ranges relevant to CO2 pipelines (100-bar) and CO2 gas turbines (300-bar)….
…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,…
…time, looking back at the development of steam cycles, early electrical generators, gas turbines (chart below). Improving net EROEIs may determine the ultimate share of renewables in the future energy…
…accountable, driven by numbers, per pages 16-21. The work draws on five-years of modelling of solar costs, onshore wind, offshore wind, gas turbines, coal plants, nuclear plants, hydro and diesel…
…percent per minute, or MW per minute). Hydro power and simple cycle gas turbines offer the best short-term performance, ramping immediately and rapidly. Next come combined cycle gas plants, then…
…compare this with the heating-melting temperatures of materials, maximum temperatures of structural materials, typical combustion temperatures, typical refinery processes and the hottest gas turbines. These high temperatures cause unavoidable volatilization…
