Market Power in Electricity Markets

, 2019
Electricity markets exhibit unique price dynamics not found elsewhere in other commodity markets. Characteristics such as limited storability, highly inelastic demand, and physical laws requiring continuous production to match consumption cause erratic price dynamics and short periods of extremely high prices known as spikes.

Machine Learning‐Assisted KCl‐CaCl2‐LiCl Electrolyte Design for Low‐Temperature, High‐Performance Calcium‐Based Liquid Metal Batteries

Advanced Science, EarlyView.
A machine learning‐assisted framework optimizes the KCl‐CaCl2‐LiCl ternary electrolyte. The optimized 13:35:52 mol% composition enables Ca‐based liquid metal batteries to operate stably at 480 °C, with >99.5% coulombic efficiency, ultralow self‐discharge, and excellent cycling stability, advancing low‐temperature large‐scale energy storage.

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates

Advanced Science, EarlyView.
Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

Reconstruction of Ultrafine MnS‐Induced Vacancy‐Rich Co9S6.29 Precatalysts in Mesoporous S‐Doped N‐Rich Hollow Carbon Nanotubes Enables Dynamic O‐Vacancy Cycling for High‐Performance Zn‐Air Batteries

Advanced Science, EarlyView.
We develop vacancy‐rich Co9S6.29 precatalysts formed via ultrafine MnS‐induced lattice distortion in mesoporous S‐doped N‐rich hollow carbon nanotubes (CM@SNHCTs). This CM@SNHCT precatalyst is reconstructed into catalytically‐active cathode phases that enable efficient oxygen reduction/evolution reactions (ORR/OER) through dynamic O‐vacancy formation ...

Promoting Electroreduction CO2 to Multi‐Carbon Products by Tailoring the *H Availability With Optimized Interfacial H2O Configuration

Advanced Science, EarlyView.
A catalysis system with adjustable interfacial H2O configuration was conducted by introducing ionomer into Cu. The increasing proportion of K+‐H2O can enhance the dissociation of H2O and improve the generation ability of *H, and the increasing proportion of 4‐HB‐H2O can accelerate the transfer speed of *H to *CO intermediates with the aid of strong ...
