  • Liquid Solar Fuels—Fundamental Science to Enable Solar Fuels Beyond Hydrogen
    Liquid Solar Fuels—Fundamental Science to Enable Solar Fuels Beyond Hydrogen Sunlight is Earth’s most abundant energy resource. Remarkable advances in photovoltaic technologies are allowing society to better capitalize on this resource for electricity generation. Harnessing the power of the sun to produce energy-rich chemicals directly from abundant feedstocks such as water, carbon dioxide (CO2), and nitrogen (N2) promises a plentiful supply of sustainable, transportable, and storable solar fuels to meet future US energy needs. Furthermore, solar fuels can provide pathways for efficient chemical energy storage to complement existing electrical energy storage. Solar fuels can also produce diverse chemicals, products, and materials with low environmental impact. Solar fuels generation—often termed artificial photosynthesis—involves the direct conversion of solar energy to chemical energy using man-made materials and chemical processes. Significant progress has been made to boost the efficiency of solar-driven hydrogen production. Much less progress has been made in the area of liquid solar fuel, an approach that requires chemically transforming CO2 and other small molecules into promising fuel targets. Hydrocarbons and/or oxygenates produced from CO2 conversion will be compatible with existing fuels infrastructure. They could also be valuable for production of commodity chemicals and materials. The generation of ammonia and other nitrogen-containing species, which can be used as fuels, fertilizers, and other commodities, presents an opportunity

  • Metal Oxides Applied to Thermochemical Water-Splitting for Hydrogen Production Using Concentrated Solar Energy
    chemengineering Review Metal Oxides Applied to Thermochemical Water-Splitting for Hydrogen Production Using Concentrated Solar Energy Stéphane Abanades Processes, Materials, and Solar Energy Laboratory, PROMES-CNRS, 7 Rue du Four Solaire, 66120 Font Romeu, France; [email protected]; Tel.: +33-0468307730 Received: 17 May 2019; Accepted: 2 July 2019; Published: 4 July 2019 Abstract: Solar thermochemical processes have the potential to efficiently convert high-temperature solar heat into storable and transportable chemical fuels such as hydrogen. In such processes, the thermal energy required for the endothermic reaction is supplied by concentrated solar energy and the hydrogen production routes differ as a function of the feedstock resource. While hydrogen production should still rely on carbonaceous feedstocks in a transition period, thermochemical water-splitting using metal oxide redox reactions is considered to date as one of the most attractive methods in the long-term to produce renewable H2 for direct use in fuel cells or further conversion to synthetic liquid hydrocarbon fuels. The two-step redox cycles generally consist of the endothermic solar thermal reduction of a metal oxide releasing oxygen with concentrated solar energy used as the high-temperature heat source for providing reaction enthalpy; and the exothermic oxidation of the reduced oxide with H2O to generate H2. This approach requires the development of redox-active and thermally-stable oxide materials able to split water with both high fuel productivities and chemical conversion rates. The main relevant two-step metal oxide systems are commonly based on volatile (ZnO/Zn, SnO2/SnO) and non-volatile redox pairs (Fe3O4/FeO, ferrites, CeO2/CeO2 δ, perovskites).

  • Molecular Engineering of Organic Photosensitizes for P-Type Dye
    Molecular Engineering of Organic Photosensitizes for P-type Dye-Sensitized Solar Cells and the Immobilization of Molecular Catalyst for the Hydrogen Evolution Reaction THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Damian Richard Beauchamp Graduate Program in Chemistry The Ohio State University 2016 Master's Examination Committee: Yiying Wu Ph.D., Advisor James Cowan Ph.D. Copyright by Damian Richard Beauchamp 2016 Abstract Solar energy has become an important component in the clean energy mix. There are several different kinds of solar cells that have been developed over decades. The focus of the first three chapters will be p-type dye-sensitized solar cells (DSSCs), which are omnipotent for obtaining high efficiency and cost effective tandem DSSCs. The efficiency of p-type DSSCs lags behind their n-type counterpart due to being less investigated. Herein, the attempts to increase performance of the p-type component via molecular engineering of organic photosensitizers is described. Through the addition of bulky hydrophobic alkyl chains performance can be enhanced, though it was found that the location of these alkyl chains is a critical factor. Additionally, by adopting a double- acceptor single-donor design, as described in chapter 3, when employing the commonly used triphenylamine donor moiety, one can simultaneously increase the molar extinction coefficient while reducing the synthetic steps yielding one the fields top performing photosensitzers. In addition to the conversion of solar energy to electrical energy, the storage of intermittent renewable energy is important. Energy can be stored mechanically (e.g.

  • 201126 Entering Into an Advisory Agreement with Akira Fujishima
    November 26, 2020 < Press Release > Entering into an advisory agreement with Akira Fujishima, Professor Emeritus, Tokyo University of Science, a World-renowned Chemist and the Discoverer of Photocatalytic Reactions. - Photocatalytic research launched in pursuit of environmental protection and hygiene management, which are issues facing modern society - Aderans Co., Ltd. (headquartered in Shinjuku-ku, Tokyo; Group CEO, Representative Director and President Yoshihiro Tsumura) promoting the wellness industry of hair, beauty and health, has concluded an advisory contract with Akira Fujishima, a world-renowned chemist, professor emeritus at Tokyo University of Science and discoverer of photocatalytic reactions, in conjunction with the launch of its hygiene business using photocatalytic technology. In response to the recent increase in awareness of hygiene management, Aderans will launch a hygiene business using photocatalysts as a part of SDGs activities, based on the philosophy of contributing to the hygienic environment of society. In addition, we will establish a new research facility for photocatalyst in our “Aderans Niiza Artificial Hair Research Institute” (Niiza City, Saitama Prefecture) to promote full-scale research and development. Accordingly, we have invited Professor Emeritus Fujishima, the father of photocatalyst and a leading researcher, to become our advisor and ask for his technical cooperation in our photocatalytic business. In 1967, while a graduate student at the University of Tokyo, Professor Emeritus Fujishima first discovered that a photocatalytic reaction occurred on the surface of titanium dioxide when a titanium dioxide electrode in aqueous solution was exposed to strong light. This phenomenon was later termed the “Honda-Fujishima Effect” in combination with the name of his co-researcher, Kenichi Honda.

  • Can S Olar Energy Fuel Th E W Orld ?
    Photo: Anders Karlqvist Anders Photo: Can Solar Energy Fuel the World? Paul Hudson and Mathias Uhlen Science for Life Laboratory, KTH Royal Institute of Technology, Stockholm, Sweden The primary motivation for developing renewable energy is to slow the accumulation of harmful greenhouse gases caused by combusting fossil fuels. A secondary motivation is to create a sustainable supply of energy for future societies. Though peak oil or peak gas is unlikely to occur soon, supplies of these are often unevenly distributed and at the whim of other nation states. In contrast, solar energy is plentiful enough everywhere, even in Northern Europe. Solar energy has developed rapidly in OECD countries as a significant component of electricity generation in the form of photovoltaics (PV), wind turbines, and biomass combustion. Complementary energy storage technologies have also rapidly expanded. An important question is whether these renewables, in particular low-cost solar photovoltaics, can provide a significant amount of world energy in the medium-term future (by 2050). In this essay, we highlight the advances of solar energy to produce liquid, fungible fuels. 34 35 The world used 162,000 TWh of energy in 2015 (1), which is three times upgraded to methane or other motor fuels. In Sweden, GoBiGas (Göteborg more energy than it did in 1965. Estimates are that by 2050 the world’s most Energi) collects waste biomass for thermal gasification to synthesis gas, which populous countries will have slowed growth, and world energy usage will is then catalytically upgraded to methane. A similar project was initiated by begin to level off at approximately 250,000 TWh (2).

It is an important source of renewable energy, whose tech- nologies are broadly characterized as, either passive solar or active solar depending on the way they capture and distribute solar energy or convert it into solar power. The passive solar techniques include orienting architecture to the sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
