Is There Enough Metal to Replace Oil?
A key issue for the accomplishment of renewables is power storage because of the impact of wind and solar intermittency, both of which are highly intermittent. Most studies assume gas will be the buffer for intermittency. Other than using fossil fuel such as gas as a buffer, an adequate power storage system to handle intermittency will require 30 times more material than what electric vehicles require with current plans, meaning the scope is much larger than the current paradigm allows.

Techno-economic analysis of self-sustainable thermophotovoltaic systems for grid-scale energy generation
To facilitate the widespread adoption of renewable energy, dispatchable, zero-emission power sources are essential for grid stability. This work performs a comprehensive techno-economic analysis of a self-sustainable thermophotovoltaic (TPV) system, an architecture that integrates solar charging to function as a standalone power generation asset. Using theory-based models for air-bridge InGaAs and Si diode cells, our analysis reveals that while the system is not currently competitive from a pur…

Thailand develops solar plan for community power supply
Thailand’s Ministry of Energy says it is advancing a community solar plan to add up to 1.5 GW of capacity through small ground-mounted projects selling power to local consumers at THB 2.25 ($0.07)/kWh under long-term contracts.

Neighbors with solar panels can now trade energy directly with each other, thanks to a breakthrough cloud-based system from Washington State University.
The platform lets communities share power locally, cutting energy costs by up to 12% in testing. It's a glimpse of how neighborhoods could become mini power grids, keeping solar energy local instead of sending it back to utilities.

Community-based energy trading system for home solar-plus-storage
A research team led by Washington State University has developed a cloud-based system for trading and sharing energy from solar panels and batteries within a neighbourhood. The concept displayed potential energy cost savings of around 12% over a five-day test period.

Coronal mass ejection arrival forecasting with the drag-based assimilation of satellite observations
Forecasting the arrival of coronal mass ejections (CMEs) is vital for protecting satellites, power systems, and human spaceflight. We present HELIOPANDA: Heliospheric Observer for Predicting CME Arrival via Nonlinear Drag Assimilation, a framework that integrates the Drag-Based Model (DBM) with spacecraft observations using iterative parameter estimation and Kalman filter assimilation. We introduce a method for estimating the solar wind speed $w$ and drag parameter $γ$, two key but usually unk…

Scientists report experimental breach of Shockley-Queisser efficiency limit for silicon solar cell
A Chinese-US research group claims to have achieved a power conversion efficiency of over 50% in an n-type single-junction solar cell by inhibiting light conversion to heat at extremely low temperatures. The result was achieved at temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero.
