Descrizione del progetto
Miscelazione dell’idrogeno nelle reti del gas per decarbonizzare il settore del gas
L’UE ha fissato un obiettivo vincolante di riduzione delle emissioni del 45 % rispetto ai livelli del 1990, entro il 2030. Una delle azioni correlate comprende l’aumento della quota di energie rinnovabili nel consumo energetico degli Stati membri dell’UE. L’idrogeno verde prodotto attraverso l’elettrolisi a energia rinnovabile sarà determinante per integrare i mercati dell’elettricità e del gas difficili da decarbonizzare. Ciò può essere realizzato fornendo l’idrogeno attraverso la rete di gasdotti esistenti per il gas naturale. Il progetto HIGGS, finanziato dall’UE, si propone di identificare e colmare le lacune di conoscenza sull’impatto di elevate quantità di idrogeno sull’infrastruttura del gas e sui suoi componenti. Per raggiungere il suo obiettivo, il progetto mapperà le barriere tecniche, legali e normative, contribuirà a determinare la fattibilità economica dell’iniezione di idrogeno nella rete del gas e sperimenterà varie soluzioni tecniche.
Obiettivo
The new policies and the revised renewable energy Directive are fixing ambitious targets for 2030: renewable energy target of at least 32% and an energy efficiency target of at least 32.5%. When the policies are fully implemented, they will lead to a great reduction on emissions for the whole EU, around 45% by 2030 (relative to 1990 GHG emission). The EU framework towards GHG emissions reduction is based in six key areas of action, including the deployment of renewable energy production, decarbonising heating and cooling applications (which vastly relies on fossil fuels), and reducing the emissions on the transport sector. Therefore, the integrated energy markets in the EU shall allow important transformations to provide more flexibility and be better placed to integrate a greater share of renewable energies, allowing also a more independent energy system.
In this context, Hydrogen can play a pivotal role as energy vector allowing coupling the energy sectors (produced by electrolysis) , and as an alternative fuel in hard to electrify sectors. To facilitate that a high amount of hydrogen is produced by RE, existent gas infrastructure could be a way of transporting hydrogen between production point and final use. Therefore, hydrogen injection into the gas grid could support gas-electricity sector coupling and opening the role of hydrogen as a way of decarbonising the gas usages.
HIGGS project aims to pave the way to decarbonisation of the gas grid and its usage, by covering the gaps of knowledge of the impact that high levels of hydrogen could have on the gas infrastructure, its components and its management.
To reach this goal, several activities, including mapping of technical, legal and regulatory barriers and enablers, testing and validation of systems and innovation, techno-economic modelling and the preparation of a set of conclusions as a pathway towards enabling the injection of hydrogen in high-pressure gas grids, are developed in the project.
