“…Nutzt man temporär verfügbare Energiequellen, kann Wasserstoff erzeugt werden, der als Energiespeicher oder als Treibstoff in der Wasserstoff‐Mobilität genutzt werden kann. Auch eine Einspeisung ins Erdgasnetz kann sinnvoll sein . Darüber hinaus ist Wasserstoff ein guter Ausgangspunkt, um Grundchemikalien wie Ammoniak oder Methanol herzustellen.…”

Nachhaltigkeit ist ein Begriff, der eine inflationäre Entwicklung genommen hat. Hier wird die Frage erörtert, wie in der Zukunft die Versorgung mit kohlenstoffbasierten Rohstoffen gesichert werden kann, ohne die Natur zusätzlich zu belasten. Es wird gezeigt, dass ein nachhaltiger Brückenbau sinnvollerweise auf den beiden Pfeilern Sonnenenergie und CO 2 beruhen sollte. Die natürliche Fotosynthese liefert Biomasse, aus der höherwertige Chemikalien hergestellt werden können, während die künstliche Fotosynthese Kohlenwasserstoffe und/oder Oxigenate zur Herstellung von Kraftstoffe und Grundchemikalien liefert.Sustainability is a term which has taken an inflationary trend. This article discusses the question, how the supply of carbon-based raw materials can be ensured in the future without additional impact on nature. It is shown that a sustainability bridge structure should be based naturally on both pillars solar energy and CO 2 . Natural photosynthesis delivers biomass which could be raw material for the production of higher valued chemicals, while artificial photosynthesis delivers hydrocarbons and/or oxigenates from which fuels and basic chemicals can be produced.

“…The hydrocarbons can then be reconverted to electric power, used for mobility, or as chemical feedstock. [16][17][18][19][20][21] A comparative assessment of the proposed energy storage systems is required to support decision makers. However, energy storage systems producing fuels or chemicals cannot be compared directly to energy storage systems producing power due to their different products.…”

A large variety of energy storage systems are currently investigated for using surplus power from intermittent renewable energy sources. Typically, these energy storage systems are compared based on their Power-to-Power reconversion efficiency. Such a comparison, however, is inappropriate for energy storage systems not providing electric power as output. We therefore present a systematic environmental comparison of energy storage systems providing different products. As potential products, we consider the reconversion to power but also mobility, heat, fuels and chemical feedstock.Using life cycle assessment, we determine the environmental impacts avoided by using 1 MW h of surplus electricity in the energy storage systems instead of producing the same product in a conventional process. Based on data for several countries including the United States, Brazil, Japan, Germany and the United Kingdom, our analysis determines the highest reduction of global warming and fossil depletion impact for using surplus power in heat pumps with hot water storage and battery electric vehicles. Third highest environmental benefits are achieved by electrical energy storage systems (pumped hydro storage, compressed air energy storage and redox flow batteries). Environmental benefits are also obtained if surplus power is used to produce hydrogen but the benefits are lower. Our environmental assessment of energy storage systems is complemented by determination of CO 2 mitigation costs. The lowest CO 2 mitigation costs are achieved by electrical energy storage systems. Broader contextEnvironmental impact reduction is the major motivation for increasing the use of renewable energies. Since renewable energy sources like wind and solar are intermittent in nature, their increased installation leads to unused surplus power. Therefore, storage for surplus power is required. Since the potential of pumped hydro storage as the only installed large scale storage system is nearly exhausted, a large variety of concepts are currently investigated to use the surplus power. The proposed concepts span from electrical storage over storage in battery electric vehicles to production of hydrogen. Hydrogen can then be used in several ways including reconversion to power in fuels cells or conversion of hydrogen with CO 2 to hydrocarbons. However, surplus power is limited and therefore only storage systems with the highest contribution to the reduction of environmental impacts should be implemented. This article therefore provides a method to compare energy storage systems based on their environmental impact reductions using life cycle assessment.
