One third of industrial processes occur at high temperatures above 1300 K, but current methods of waste heat recovery at these temperatures are limited. Now, reduced graphene oxide is shown to be a highly efficient and reliable thermoelectric material up to 3000 K.
Smart integrated transport and energy systems need to interact with end users to enable the exploitation of demand flexibility. New research shows that relying on assumptions about user behaviour, rather than on data-based empirical models, inflates the benefits of smart-charging programmes.
The rise of prosumers has led to creation of virtual power plants and peer-to-peer trading to help manage a diverse and distributed array of energy sources. This Perspective proposes the federated power plant, which combines these concepts to meet some of their individual challenges and offer new value.
Biological photovoltaic devices (BPVs) use photosynthetic microorganisms to produce electricity, but low photocurrent generation impedes their application. Now, a micro-scale flow-based BPV system is reported with power density outputs similar to that of large-scale biofuels.
