Abstract Solid-oxide electrolysis technology (SOEC) can efficiently convert electricity from renewable sources into H2 via steam electrolysis, or syngas (a mixture of H2 and CO2) via co-electrolysis of steam and CO2. Co-SOEC provides the advantage of better thermal integration for standalone applications or with other industrial processes. In this paper two promising cases are investigated from the perspective of life-cycle assessment to evaluate the potential of reducing carbon emissions: (1) coupling co-SOEC with a cement plant, and (2) integrating co-SOEC into a biomass gasification plant. Life cycle assessment was performed based on the collection of comprehensive information regarding the electricity sources for different scenarios and a sensitivity analysis was included to verify the consistency of the results. The results show that in both cases the co-electrolysis system can be beneficial in terms of reduction of global warming potential, although it depends heavily on the geographic location and on the share of renewable energy. The highest benefits among the cases reviewed were found in the case of a coal-fed cement plant, where annual CO2 savings reached up to 2.39E + 05 tonnes CO2-eq in France with 23.6% of the electricity provided by photovoltaics (PV). In Germany, on the other hand, both cases first show benefits when the renewable share reaches a very high percentage of the electricity input: 50% provided by PV for the case of the cement plant and 82% for the case of a biomass-gasification unit. Since electricity input is the main impact concerning power-to-gas applications, the carbon content of the electricity grid mix is very important. As grid mixes become ‘cleaner’ in the future with more renewable share in the electricity generation in every country, the investigated applications are expected to provide even higher benefits.

The development of Li-ion batteries has enabled the re-entry of electric vehicles into the market. As car manufacturers strive to reach higher practical specific energies (550 Wh/kg) than what is achievable for Li-ion batteries, new alternatives for battery chemistry are being considered. Li-Sulfur batteries are of interest due to their ability to achieve the desired practical specific energy. The research presented in this paper focuses on the development of the Li-Sulfur technology for use in electric vehicles. The paper presents the methodology and results for endurance tests conducted on in-house manufactured Li-S cells under various accelerated ageing conditions. The Li-S cells were found to reach 80% state of health after 300–500 cycles. The results of these tests were used as the basis for discussing the second life options for Li-S batteries, as well as environmental Life Cycle Assessment results of a 50 kWh Li-S battery.

Wind energy is the world's fastest growing energy source. Specifically in the recent decade, offshore wind energy is the technology that has developed the fastest due to the stronger and stable winds produced at sea and the huge areas where it can be employed. Electricity production from wind sources has seen high growth along with wind turbine capacity, foreseeing a linear evolution in the next decade. Additionally, it has been well demonstrated recently that the larger the power per wind turbine unit installed, the lower the levelized cost of energy. Second-generation high-temperature superconductor synchronous generators with direct-drive technology (2GHTSDDSG) for offshore wind energy applications have recently emerged as an alternative to consider instead of permanent-magnet direct-drive synchronous generators (PMDDSG), due to their lower dimensions and low weight per megawatt. This paper contains a detailed “cradle-to-gate” life-cycle assessment of the 15-MW 2GHTSDDSG and PMDDSG, using GaBi 6 commercial software and PE International Professional and Ecoinvent 2.2 databases, as a result of quantifying each component required for the production. After a detailed inspection of each component fabrication, conclusions and recommendations are obtained and presented.

This paper illustrates the Life Cycle Analysis (LCA) activities performed during the preparation of the Spanish Product Category Rules (PCR) relative to the construction sector. Specifically, the study presents the results obtained from the life cycle analysis of the floor and wall tile sector, which served as the basis for the drafting of the PCR required for the definition of Environmental Product Declarations (EPD). More than 50 Spanish companies in the ceramic tile sector participated in the study, providing inventory data on the manufacture of their products. Additionally, bibliographic information and the GaBi 4 software database by PE International were used to complete background and generic data, such as those related to energy and transportation processes.
EPDs are voluntary declarations based on LCA studies that permit the disclosure and dissemination of environmental information quantified over the life cycle of a product. The definition of PCRs for ceramic tiles was performed in accordance to the UNE EN ISO 14025 and ISO 21930 standards and they have been submitted to industries and professional association public consultations. PCRs have been developed in the context of the DAPc program (promoted by the Catalan Government and CAATEEB) and represents the first ecolabelling activity for building products in Spain.
