Making solar power available on demand
In an article on The Conversation website, Vera Moerbeek, Doctorante en physique, Centre national de la recherche scientifique (CNRS); Université de Perpignan Via Domitia writes about the next generation of energy storage: thermal batteries using thermophotovoltaics (TPV) that could make solar power dispatchable without relying on lithium-ion batteries. What are your views? How next‑generation … Continue reading Making solar power available on demand
Electric vehicles: separating legitimate concerns from misinformation
Stuart Braun writes on the Deutsche Welle website about countering common myths about electric vehicles, especially around batteries, critical minerals, fires and supply chains, while putting these concerns into context. Claims that electric vehicle batteries are tainted by exploitative mineral supply chains are discrediting non-fossil cars as electrified road transport booms. Are electric car … Continue reading Electric vehicles: separating legitimate concerns from misinformation
How a sunburn inspired a breakthrough in energy storage
Stranger things have happened, no doubt. But a sunburn had that eureka moment. Chris Baraniuk writes on the BBC News website about the breakthrough in energy storage. How sunburn inspired a new way to store energy The sun does shine, sometimes, in Boston – but not like this. When chemistry professor Grace Han first … Continue reading How a sunburn inspired a breakthrough in energy storage
Energy in Demand News, May 10-11, 2026
It is encouraging that the OECD has published a Data Explainer that details the need for governments to step up policies promoting more efficient energy use. It focuses on 13 energy efficiency policies, including minimum energy performance standards (MEPS), public financing mechanisms for buildings and industry (e.g. green mortgages, vendor credits), fuel economy standards and … Continue reading Energy in Demand News, May 10-11, 2026
