Gas turbines and CHP: technology leaders?
The aim of this data-file is to profile thirty leading companies in gas turbines and smaller-scale CHPs, based on their disclosures and patent filings. In each case, we describe the…
A new case for gas: what if renewables get overbuilt?
…meter. The theory, technical details and rationale for these CHP systems are explained on pages 10-11. Economics of combined heat and power and reviewed in detail on pages 12-14, focusing…
Mainspring Energy: linear generator breakthrough?
Linear generator technology can convert any gaseous fuel into electricity, with c45% electrical efficiency, and >80% efficiency in CHP mode. This data-file reviews Mainspring Energy’s patents. We conclude that the…
Combined heat and power: the economics?
…the grid, due to high efficiency capturing and using exhaust heat in CHPs. Economic sensitivities can be stress-tested, including to power prices, gas prices, thermal efficiencies and system sizes (examples…
Landfill gas: rags to riches?
…CHP (pages 9-12), cleaning up to pipeline spec (pages 13-14), further cleaning into CNG transportation fuels (pages 15-16) and biogas-to-jet (page 17). Perspective is crucial. The ultimate carbon abatement costs…
Absorption chillers: the economics?
This data-file approximates the costs of absorption chillers, which perform the thermodynamic alchemy of converting waste heat (e.g., from a CHP turbine) into coldness. Today the market is small, around…
Coal versus gas: explaining the CO2 intensity?
…combined cycle gas plants average 57% efficiencies, and we are particularly excited about emerging gas-fired CHP systems that can reach 80-90% total thermal efficiencies (note below). https://thundersaidenergy.com/2021/07/01/gas-turbines-what-market-size-in-energy-transition/ (3) What about…
