The photo-driven reduction of carbon dioxide (CO2) into green and valuable solar fuels could be a promising solution to simultaneously address energy- and environmental-related problems. This approach could play an integral role in achieving a sustainable energy economy by closing the carbon cycle and allowing the storage and transportation of intermittent solar energy within the chemical bonds of hydrocarbon molecules. This Perspective discusses the latest technological advancements in photo-driven CO2 conversion via various pathways, namely photocatalysis, photoelectrocatalysis and photovoltaic-integrated systems. In addition to providing an outlook on unresolved issues concerning the said technologies, this Perspective also spotlights new trends and strategies in the structural engineering of materials to meet the demands for prominent CO2 photoreduction activity as well as spearhead the ground-breaking advances in the field that lead to the translation of CO2 photo-driven technologies from the laboratory to industrial-scale applications.

The authors should be commended for their pioneering research work on structural cladding and energy-dissipating connections. This discussion has been written to help ensure that this research, which is multidisciplinary in nature, leads to practical applications. All structural engineering researchers must recognize that structural cladding design is one of the broadest building-related research topics that can be tackled. They should not focus only on topics that have roots in structural engineering alone, and thus deny the integral role of structural cladding in building design. The importance of a building systems approach must be recognized. In doing so, the role of the architect will become obvious, and a promising collaborative effort will be established. This discussion is made from the perspective of a background in structural engineering and architectural research and practice.

ABSTRACT The possibility of providing the acetogenic microorganism Sporomusa ovata with electrons delivered directly to the cells with a graphite electrode for the reduction of carbon dioxide to organic compounds was investigated. Biofilms of S. ovata growing on graphite cathode surfaces consumed electrons with the reduction of carbon dioxide to acetate and small amounts of 2-oxobutyrate. Electrons appearing in these products accounted for over 85% of the electrons consumed. These results demonstrate that microbial production of multicarbon organic compounds from carbon dioxide and water with electricity as the energy source is feasible. IMPORTANCE Reducing carbon dioxide to multicarbon organic chemicals and fuels with electricity has been identified as an attractive strategy to convert solar energy that is harvested intermittently with photovoltaic technology and store it as covalent chemical bonds. The organic compounds produced can then be distributed via existing infrastructure. Nonbiological electrochemical reduction of carbon dioxide has proven problematic. The results presented here suggest that microbiological catalysts may be a robust alternative, and when coupled with photovoltaics, current-driven microbial carbon dioxide reduction represents a new form of photosynthesis that might convert solar energy to organic products more effectively than traditional biomass-based strategies.

Energy Economy

The conversion of renewable energy especially solar energy into versatile fuels is a key technology for an innovative and sustainable energy economy. To finally benefit from solar fuels they have to be produced with high efficiencies and low to no greenhouse gas emissions in large quantities. The final goal will most probably be the carbon free fuel hydrogen. But the main challenge is its market introduction. Therefore a strategy incorporating transition steps has to be developed. Solar thermal processes have the potential to be amongst the most efficient alternatives for large scale solar fuel production in the future. Therefore high temperature solar technologies are under development for the different development steps up to the final goal of carbon free hydrogen. This paper discusses the strategy based on the efficiencies of the chosen solar processes incorporating carbonaceous materials for a fast market introduction and processes based on water splitting for long term solar hydrogen generation. A comparison with the most common industrial processes shall demonstrate which endeavors have to be done to establish solar fuels.

The Status

The greenhouse gas represented by carbon dioxide is having a negative impact on the earth's ecology. The goal of carbon neutrality is to reduce carbon emissions to zero through complete elimination or dynamic balance. Therefore, achieving the goal of carbon neutrality is conducive to restoring the earth's ecology and reducing global temperature. The main ways to achieve carbon neutrality include the use of renewable energy to replace fossil energy and carbon capture and sequestration. There is no carbon dioxide involved in the process of renewable energy production, and carbon capture and storage can directly eliminate carbon dioxide. This article reviews the ways to achieve carbon neutrality: the status quo, advantages and disadvantages of renewable energy and carbon capture and sequestration, and analyzes the current development and problems and challenges of carbon neutrality through examples.

Abstract. Carbon dioxide concentrations in the atmosphere play an integral role in many earth system dynamics, including its influence on global temperature. Long-term trends can provide insights into these dynamics though reconstructing long-term trends of atmospheric carbon dioxide (expressed in partial pressure; PCO2) remains a challenge in paleoclimatology. One promising approach for reconstructing past PCO2 utilizes isotopic fractionation associated with CO2-fixation during photosynthesis into organic matter (Ɛp). Previous studies have focused primarily on testing estimates of Ɛp derived from species-specific alkenone compounds in laboratory cultures and mesocosm experiments. Here, we analyze Ɛp derived from general algal compounds from sites at a CO2 seep near Shikine Island (Japan), a natural environment with CO2 concentrations ranging from ambient (ca. 310 µatm) to elevated (ca. 770 µatm). We observed strong, consistent δ13C shifts in several algal biomarkers from a variety of sample matrices over the steep CO2 gradient. Of the three general algal biomarkers explored here, namely loliolide, phytol, and cholesterol, Ɛp positively correlates with PCO2 in agreement with Ɛp theory and previous culture studies. PCO2 reconstructed from the Ɛp of general algal biomarkers show the same trends throughout, as well as the correct control values, but with lower absolute reconstructed values than the measured values at the elevated PCO2 sites. Our results show that naturally-occurring CO2 seeps may provide useful testing grounds for PCO2 proxies and that general algal biomarkers show promise for reconstructing past PCO2.
