ENEA is the National Agency for New Technologies, Energy and Sustainable Economic Development, a public body aimed at research, technological innovation and the provision of advanced services to enterprises, public administration and citizens in the sectors of energy, the environment and sustainable economic development (article 4, Law no. 22 of 28 December 2015)". ENEA has highly qualified personnel, advanced laboratories, experimental facilities and excellent instruments for the realisation of projects, studies, tests, assessments, analyses and training services, with particular reference to product and process innovation and the valorisation of results to contribute to the development and competitiveness of the national economic system. Since its foundationin the 1960s, its strengths have been applied research, technology transfer and technical-scientific support to companies, associations, territories, central and local administrations: for this reason - unlike other research institutions - the Agency depends on the Ministry of Economic Development. Its focus sectors are energy technologies (renewable sources, energy storage, smart grids), for which the Agency is also the coordinator of the Energy National Technology Cluster, nuclear fusion and nuclear safety (the Agency is the reference national research coordinator), energy efficiency (with the National Agency for Energy Efficiency), technologies for cultural heritage, seismic protection, food safety, pollution, life sciences, strategic raw materials, climate change. Among the emerging issues, is circular economy, which sees ENEA designated as the National Agency for the efficient use of resources and sustainable mobility. ENEA reinforces its efforts by collaborating with numerous national and international research bodies and institutions like Texas Tech University, Stanford Research Institute, New Delhi University, the Chinese Academy of Sciences, ICTP, TWAS, and participates in technological platforms and networks like EERA (European Energy Research Alliance), ECRA (European Climate Research Alliance), MEDENER, and Enterprise Europe Network, the largest network of services supporting competitiveness and innovation for SMEs.

Additional Technical Information:
PRAGA is a full equipped gasification plant based on a 200 kWth updraft gasifier which was installed in June 2010 to test the co-gasification of biomass and sorted (plastic) MSW. The nominal input of the gasifier is 20-30 kg/h of feed with a maximum plastic content of 15%.
The plant is operated slightly above atmospheric conditions and it uses a mix air/steam as gasification medium introduced under a moving grate at the bottom of the gasifier. The produced gas (roughly 80 Nm3/h) moves upward from the bottom of the gasifier while the biomass particles travels downwards progressively trough zones of drying, pyrolysis, reduction and combustion.
The gas cleaning section is composed by a biodiesel scrubber and two coalescer filters in series. By organic scrubbing, most of the organic and inorganic compounds (tars, HCl, etc.) are removed from the gas, while in the coalescer filters the oil drag particles would be removed. This unit also allows a temperature reduction of the syngas coming out from the gasifier (about 300-400 °C). After the cleaning the gas is destined to a flare or to a hydrogen enrichment section. The facility is unique since is equipped of several solid, liquid (tar) and gas sampling probes/lines to fully characterise the process, moreover it is extensively automated and remotely controlled with in field flow-meters, pressure and temperature measurements along the gasifier and the clean-up line for on-line monitoring. Dedicated gas chromatographic analysis (off-line) have been assessed for gas quality and minor species characterisation while online devices based on FTIR have been planned and will be available for the BRISK service time. Tar are sampled after scrubber and coalescer filters for the off-line analysis, both ponderal and fine determination by GC-MS. The installation allows evaluating the process efficiency, the gasifier performance and the gas composition of the plant varying of feedstock specifications, RDF/biomass ratio and gasification medium. A major route to enhance the gasifier flexibility is the use of oxygen enriched air as gasifying agent. The experimental work is routinely coupled with modelling studies of the gasification process to estimate the effect of the main operating conditions and provide a theoretical basis for experimental results interpretation and evaluation (ChemCad, GaBi). An exhaustive chemical and physical determination of feedstock and product streams will be included with the granted Access, as well the online recorded measurements. More details can be found in literature, e.g. Energy Fuels 2014, 28, 3948−3956).
