Special Issue Information

Dear Colleagues,

The global goal is to bring greenhouse gas emissions to zero within the second half of the 21st century, as ratified in the 2015 Paris Agreement. Such a challenging target implies developing novel methods and devices, or improving existing ones, to extract more energy from renewable resources, at low cost. Energy from wind, tides, and waves, and geothermal energy, have been identified as leading technology options to decarbonise the energy system worldwide.

The significant increase in computing power over the past decades has motivated the development of numerical tools, which can be efficiently used for the design and control of renewable energy systems. Authors are invited to submit research and progress related to the development and use of numerical methods for renewable energy applications. This Special Issue will feature original research in these areas, including but not limited to:

  • Offshore/onshore wind energy
  • Tidal/wave renewable energy
  • Geothermal energy.

I invite you to submit a manuscript to this Special Issue, which should ideally include a clear numerical component, for instance Computational Fluid Dynamics (CFD), numerical optimization, deep learning, etc., demonstrating how numerical methods, models, and codes can be applied for the design, study and/or optimization of existing and/or novel renewable energy systems.

Geothermal energy is a reliable and mature energy source, but it represents less than 1% of the total renewable energy mix. While the enhanced geothermal system (EGS) concept faces technical validation challenges and suffers from public acceptance issues, the development of unconventional deep-well designs can help to improve their efficiency and reliability. Modelling single-EGS-well designs is key to assessing their long-term thermal performances, particularly in unconventional geological settings. Numerical results obtained with the T2WELL/EOS1 code have been validated with available experimental data from a deep borehole heat exchanger (DBHE), where a temperature of 358 C has been measured at a depth of 1962 m. Based on a calibrated model, the thermal performances of two enhanced thermal conductive DBHEs with graphite were compared for high geothermal gradients. The analysis highlights the potential recovery of a variable fraction of vapour. Graphite used along the well appears to be the most suitable solution to enhance the thermal output by 5 to 8% when compared to conventional wells. The theoretical implementation of such well in the Newberry volcano field was investigated with a single and doublet DBHE. The findings provide a robust methodology to assess alternative engineering solutions to current geothermal practices. Full article
