A technology evaluation method for assessing the potential contribution of energy technologies to decarbonisation of the Italian production system

A methodology focused on technology evaluation is proposed to give a footprint of the development potential of energy technologies in Italy. The approach focuses on the impact on climate, the potential in terms of R&D, the competitiveness of Italian companies and their diffusion on the territory. A reference Catalogue was realised in the framework  of the ‘Technical Board on Decarbonisation of the Economy’, established by the Italian Presidency of the Council of Ministers. 36 datasheets, containing quantitative and qualitative information on Technology Readiness Level (TRL), efficiency, environmental and economic impacts and policy aspects were filled by 70 experts for each technology. Some data were extracted from the Catalogue - TRL, CO2 emissions, developers, and centres of excellence - and further analysed with other information relating to the Italian production and innovation system collected from the National Enterprise Registry (ASIA). Companies and research centres  are involved in development of technologies based on Renewable Energy Sources (RES) and Energy Storage (ES) with different levels of TRL and high potential for mitigating effects on climate. However, their distribution shows a rather inhomogeneous presence at territorial level. This evaluation provided useful elements to elaborate policy measures to support the diffusion of energy technologies

Fast Triacylglycerol Fingerprinting in Edible Oils by Subcritical Solvent Chromatography

Supercritical fluid chromatography (SFC) has witnessed a resurge of interest in the last decade, motivated by substantial progress in hardware capabilities and the development of specifically tailored packing materials. Meanwhile, the technique has been transitioning to the use of mobile phases in which an organic co-solvent is mixed to carbon dioxide under subcritical conditions (subFC). The use of a mobile phase modifier will also affect the selectivity, and extend the range of SFC-amenable compounds, including lipids. In this research, a subFC method was developed for the separation of triacylglycerols (TAGs) in edible oils of vegetable origin, namely borage, corn, hazelnut, olive, palm, peanut, and soybean oil. For all the samples investigated, elution of the TAG species was achieved within 8 min, the only exception being borage oil (14 min run), characterized by TAGs spanning in a wide range of partition number (PN 36–56), as constituted by fatty acids differing for alkyl chain lengths (CN 14–24), and degree of unsaturation (DB 0–9). The coupling to mass spectrometry (MS) detection allowed for the average parameters of fatty acid composition to be derived in the oil TAG constituents. A total of 121 TAGs were identified by subFC-MS, with reduced analysis time and solvent consumption (1.5 mL per analysis) compared to common chromatographic approaches. Key features of the method developed hereby are low toxicity, costs, and environmental impact. Notably, the achieved separations were conducted at room temperature, which is beneficial in terms of column life
