Nuclear power and the cost-effective decarbonisation of electricity systems – (Nuclear Energy Agency)
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.
This report explains the approach that the ORNL developed for screening a sample set of “small” coal stations for possible repowering with SMRs, including spatial modelling and initial results.
