“…Imagine a future where we could power our cars with nothing but water. , Obviously, this advancement would address the environmental , and societal issues associated with the burning of fossil fuels, allow for the development of highly sustainable technologies, − and potentially lead us to a carbon-free economy. − While this may seem like a far-fetched idea, the decomposition of water into its elemental components (oxygen and hydrogen) using electricity (or electrolytic water-splitting) has in fact been known for over 200 years, and the design and characterization of electrocatalysts which improve the efficiency of these reactions has been a priority of research efforts since its discovery and reviewed extensively. − Despite such attention, modern electrocatalysts for water-splitting reactions still fall short of industrially relevant stabilities and efficiencies. ,− Electrolytic water splitting consists of two half-cell reactions: the hydrogen evolution reaction (HER), where water is reduced to produce H 2 , and the oxygen evolution reaction (OER), where water is oxidized to produce O 2 . Both reactions must be optimized before the widespread application and industrial scale-up of electrolytic water-splitting can be achieved.…”

Making a measurement over millions of nanoparticles or exposed crystal facets seldom reports on reactivity of a single nanoparticle or facet, which may depart drastically from ensemble measurements. Within the past 30 years, science has moved toward studying the reactivity of single atoms, molecules, and nanoparticles, one at a time. This shift has been fueled by the realization that everything changes at the nanoscale, especially important industrially relevant properties like those important to electrocatalysis. Studying single nanoscale entities, however, is not trivial and has required the development of new measurement tools. This review explores a tale of the clever use of old and new measurement tools to study electrocatalysis at the single entity level. We explore in detail the complex interrelationship between measurement method, electrocatalytic material, and reaction of interest (e.g., carbon dioxide reduction, oxygen reduction, hydrazine oxidation, etc.). We end with our perspective on the future of single entity electrocatalysis with a key focus on what types of measurements present the greatest opportunity for fundamental discovery.

“…The integration of renewable energy and electric vehicles into the grid can reduce both operation costs and capital costs in building more power system assets, while effectively reducing greenhouse gas emissions. It is estimated that by 2030, carbon dioxide emissions will be reduced by up to 77.6 million tons and environmental costs will be reduced by up to USD 18.945 billion [1]. However, due to the uncertainty in and volatility of renewable energy, balancing supply and demand in the power grid become more difficult, and brings significant challenges to the unit scheduling, power grid control, and market operation of power systems [2].…”

Global fossil fuel consumption and associated emissions are continuing to increase amid the 2022 energy crisis and environmental pollution and climate change issues are becoming even severer. Aiming at energy saving and emission reduction, in this paper, a new unit commitment model considering electric vehicles and renewable energy integration is established, taking into account the prediction errors of emissions from thermal units and renewable power generations. Furthermore, a new binary CMAES, dubbed BCMAES, which uses a signal function to map sampled individuals is proposed and compared with eight other mapping functions. The proposed model and the BCMAES algorithm are then applied in simulation studies on IEEE 10- and IEEE 118-bus systems, and compared with other popular algorithms such as BPSO, NSGAII, and HS. The results confirm that the proposed BCMAES algorithm outperforms other algorithms for large-scale mixed integer optimization problems with over 1000 dimensions, achieving a more than 1% cost reduction. It is further shown that the use of V2G energy transfer and the integration of renewable energy can significantly reduce both the operation costs and emissions by 5.57% and 13.71%, respectively.
