“…PV-based fuel generation can be used to bridge the gap between peak solar power and utility load curves (2,4,5), the simplest example of which is PV-driven water splitting to generate hydrogen as a fuel. A current lack of distribution and storage infrastructure for H 2 , however, has led to slow technology adoption and thus H 2 is not yet widely used directly as a transportation fuel or for electricity generation via fuel cells (6,7).…”

Photovoltaic cells have considerable potential to satisfy future renewable-energy needs, but efficient and scalable methods of storing the intermittent electricity they produce are required for the large-scale implementation of solar energy. Current solar-to-fuels storage cycles based on water splitting produce hydrogen and oxygen, which are attractive fuels in principle but confront practical limitations from the current energy infrastructure that is based on liquid fuels. In this work, we report the development of a scalable, integrated bioelectrochemical system in which the bacterium Ralstonia eutropha is used to efficiently convert CO2, along with H2 and O2 produced from water splitting, into biomass and fusel alcohols. Water-splitting catalysis was performed using catalysts that are made of earth-abundant metals and enable low overpotential water splitting. In this integrated setup, equivalent solar-to-biomass yields of up to 3.2% of the thermodynamic maximum exceed that of most terrestrial plants. Moreover, engineering of R. eutropha enabled production of the fusel alcohol isopropanol at up to 216 mg/L, the highest bioelectrochemical fuel yield yet reported by >300%. This work demonstrates that catalysts of biotic and abiotic origin can be interfaced to achieve challenging chemical energy-to-fuels transformations.

“…The use of time‐of‐use and real‐time pricing requires investment in infrastructure, like smart meters, and proper empirical estimation of marginal costs for providing electricity for optimal rate setting. Tanaka () points to the cases with real‐time pricing with ramping costs, and suggests a new approach to managing a steep change in electricity demand which explicitly takes into account the ramping costs. Allcott () evaluated the first real‐time pricing program in the USA.…”

The increasing use of demand‐side management, as a tool to reliably meet electricity demands at peak time, has stimulated interest among researchers, consumers and producer organiza‐tions, managers, regulators and policymakers. This research reviews the growing literature on models which are used to study demand, customer base‐line (CBL) and demand response in the electricity market. After characterizing the general demand models, the CBL, based on which the demand response models are studied, is reviewed. Given the experience gained from the review and existing conditions, the study combines an appropriate model for each case for a possible application to the electricity market; moreover, it discusses the implications of the results. In the literature, these aspects are studied independently. The main contribution of this survey is attributed to the treatment of the three issues as sequentially interdependent. The review is expected to enhance the understanding of the demand, CBL and demand response in the electricity market and their relationships. The objective is conducted through a combination of demand and supply side managements in order to reduce demand through different demand response programs during peak times. This enables electricity suppliers to save costly electricity generation and at the same time reduce energy vulnerability.

“…Ref. [3] proposed that electricity demand may increase steeply during the morning hours and decrease steeply during the evening hours which should be considered in real-time pricing mechanism. However, at present, the pilot of real-time electricity price had not been promoted in China and the design of the real-time electricity pricing mechanism has not been unified, so it is thus urgent to analyse more in depth the reasonable policy of real-time electricity pricing and design the optimal real-time electricity pricing system.…”
