Wooden wind turbines?
…carbon negative turbines? If we add up all of the considerations above, we estimate there is potential to deflate the levelized costs of wind turbines by 2.5 – 10%, from…
Thermal power plant: loss attribution?
…efficiency of a wood-fired power plant is 34%. Gas turbines. We have also developed a gas-turbine variant of the model, reflecting the energy economics of the Brayton cycle from first…
Wind turbine generators: DFIGs or Rare Earth magnets?
…10-15MW turbines, especially offshore, is almost always associated with PMSG turbines. Why do wind turbines use Rare Earth magnets? The short answer is that Rare Earth magnets have greater magnetic…
Offshore Wind: Tracking Turbines with Satellites and Machine Learning?
…Yaw misalignment is a challenge in the wind industry, denoting the variation of a wind turbine’s blades from their optimal orientation facing directly into the wind. It reduces turbines’ productivity,…
Power functions: how would gas shortages change the cost curve?
…and power-electronics; and less gas, until gas prices normalized. Self-defeatingly, we would also expect less short-term decarbonization via coal-to-gas switching. Across our research we have modelled over 150 different technologies…
Methane leaks: by gas source and use

LNG liquefaction technologies: an overview?
…What compressor turbines are used in LNG plants? First generation plants used steam turbines. Second generation plants used industrial gas turbines. Recent plants use aero-derivative turbines, which have smaller footprints,…
Windy physics: how is power of a wind turbine calculated?
…offshore wind turbines. Could large wind turbines shift to using two blades? Another intriguing observation from the physics is the possibility of two-blade turbines, as an adaptation strategy that is…
Back up: does ramping renewables displace gas?
…gas power plant generation profiles. Yet our data show how ramping renewables have entrenched pre-existing gas turbines in the grid in Australia — similar to other analysis we have conducted…
Coal-to-gas switching: what CO2 abatement cost?
…of gas averaged $8.2/mcf, which translates into 2.7c/kWh-th. Thus the premium for natural gas was around 1.5c/kWh-th. Directly substituting coal fuel for gas fuel therefore incurred a cost of $80/ton…
