Oak Ridge National Laboratory (ORNL) developed the Oak Ridge Siting Analysis for Power Generation Expansion (OR-SAGE) tool in response to studies on national electrical energy supply.
This paper analyses the future of the existing Polish coal-fired power fleet and proposes retrofitting existing coal-fired units by replacing coal-fired boilers with small modular reactors.
This study assesses the future of the coal power sector by evaluating the full spectrum of retrofit decarbonization options (e.g. carbon capture, fuel conversion and replacing coal boilers with new low-carbon energy sources)
This paper proposes integrating high‑temperature thermal energy storage (HTTES) via an additional thermodynamic cycle to improve load flexibility in a 600 MW subcritical coal unit.
This executive summary proposes converting Chile’s retiring coal plants into “Thermal Storage Plants” by replacing boilers with molten‑salt steam generators charged by renewable electricity via resistive heaters, reusing the Rankine cycle and interconnection.
Achieving cost-effective decarbonisation requires structural reform of the electricity market.
MIT–INL–Exelon workshop summary on coupling thermal energy storage to Gen IV reactors to deliver flexible power: charge storage at low/negative prices and discharge to meet peaks, using nitrate/chloride salts, concrete, rock, and Brayton/Rankine cycle configurations.
The Paris Agreement crystallized the world’s commitment to reducing greenhouse gas (GHG) emissions to limit global temperature change to well below 2 °C above pre-industrial levels, while pursuing efforts to limit it to 1.5 °C
The paper develops four scenarios: I) full wind curtailment with average coal dispatch, II) no curtailment with average coal dispatch, III) no curtailment with optimal coal dispatch, and IV) partial curtailment with optimal coal dispatch, calculated across 24 hours for a coal plant and wind farm in Harbin.
Authors: Rongrong Zhai, Hongtao Liu, Chao Li, Miaomiao Zhao, Yongping Yang Researchers have explored ways to integrate renewable energy into existing coal-fired power plants in order to reduce fuel consumption and emissions while maintaining reliable electricity production. This study examines a solar-aided coal-fired power generation (SAPG) system, where solar thermal energy replaces part of the steam extraction process used to heat feedwater in conventional…
AltaRock Energy, Inc: Only with EGS can we replace coal with geothermal in a wide variety of locations. Co-locating the geothermal project on land owned by the coal plant takes advantage of the grid connection, permitting and cooling system as well as a skilled workforce. Waste water stored in ponds at the site can be…
For the purpose of the Working Group III (WGIII) contribution to the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5), a limited but still diverse set of sector-specific metrics is used to strike a balance between harmonization of approaches across sectors and adequate consideration of the complexities involved.
