6 Energy Transition projects

In terms of sustainability, Regulation (EU) 347/2013 defines that projects ­“involving two or more MSs or located on the territory of one MSs but with ­significant cross-border impact”, need contributing significantly “through ­reducing emissions, supporting intermittent renewables generation and ­enhancing ­deployments of renewable gas” in order to be labelled as PCI. ­Renewable and decarbonised gases projects enhance GHG emissions reductions that, by definition, represent cross-border benefits.

Other cross-border effects are determined by the positive externalities generated by technology and innovation diffusion across EU countries via energy transition projects implementation and scaling-up.

Anticipating those needs and considering that projects that want to apply for the PCI label must be included in the latest available TYNDP, the TYNDP 2020 for the first time opened to the submission of Energy Transition (ETR) projects: “any project which facilitates the integration of renewables, the achievement of decarbonisation and efficiency ­targets, reduction of other air pollutants, sector coupling initiatives and, more generally, all projects specifically aimed at the energy system transformation for reaching sustainability goals and not ­already included in the previous project categories”. In TYNDP 2020 ETR projects represent 30 % of the overall submitted projects (28 % if considering the overall submissions before their aggregation1).

Support to sustainability through renewables penetration is vital to achieve the decarbonisation ­targets therefore ENTSOG believes that the PCI ­assessment should consider these activities too.

In its TYNDP 2020 Opinion, also ACER welcomed the final Practical Implementation Document 2020 allowing the submission of Energy Transition projects. In its Opinion, ACER acknowledges the potential importance of renewable gas projects for the decarbonisation of the gas sector and its contribution to the climate objectives of the European ­Union.

See table 6 for a complete list of TYNDP 2020 ETR projects divided by type.

Table 6: ETR projects included in TYNDP 2020 divided per type

If compared, for example, to traditional cross-­border interconnections, in many cases ETR ­projects could be represented by smaller-capacity-size projects and more geographically distributed within a country. This is the case for example of many biomethane production facilities whose ­location is mostly dependent on the location of the biogas production location.

For this reason, for TYNDP 2020, promoters of ­Energy Transition Projects submitted their ETR projects as a virtual aggregation of more projects, when possible.

As mentioned in section 5.3.4, most of the ­submissions can be identified under one of the ­following categories: power-to-gas (P2G) and ­hydrogen related projects; biomethane production and injection; carbon capture and storage/use; ­further enable of use of gas in the form of CNG and LNG in transport sectors; reverse flow DSO-TSO.

The main technologies related to ETR projects are briefly presented below:

  • Power-to-Gas is an instrument allowing for ­optimisation of the overall energy system since it deals with excess of renewable electricity (compared to the demand) which is difficult to store in large quantities for a long time. The ­advantages based of producing renewable gases like hydrogen and synthetic methane are to provide seasonal flexibility and storage, building on existing gas network and underground storage. Already today the gas system offers over 1100 TWh of underground storage ­capacity. Existing gas Infrastructure – after technical adaption – can be used for long-term energy storage and transportation. In addition, renewable gases allow the decarbonisation of hard-to-abate sectors (heavy industry) and a more efficient use of the expected increase in generation potential coming from RES in the future.
    Power-to-Gas means a conversion of electrical power into a gaseous energy carrier. In a first step, electricity from renewable energy sources is used in an electrolyser to split water into hydrogen and oxygen. This process is called Electrolysis. An additional Methanation step can be used to synthesise the hydrogen with carbon dioxide into synthetic methane.
  • Biogas is a mixture of methane, CO₂ and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment. The precise composition of biogas depends on the type of feedstock and the production pathway.
  • Biomethane is an almost pure source of methane produced either by “upgrading” biogas (a process that removes any CO₂ and other contaminants present in the biogas) or through the gasification of solid biomass followed by methanation. Biomethane can be injected and transported through the gas grid without additional upgrades of the transmission system.
  • CCS and CCU aim to capture CO₂ emissions from point sources such as power plants and industrial processes, to prevent the release into the atmosphere. The difference between CCS and CCU is in the final destination of the captured CO₂. In CCS, captured CO₂ is transferred to a suitable site for long-term storage, while in CCU, captured CO₂ is converted into commercial products. This technology can be used also in the production of hydrogen following the Steam Methane Reforming process (SMR).
    CO₂ can be transported for storage or use via pipelines, road or maritime.

More detailed information related to project ­description and technical details can be found for each ETR in the Annex A of TYNDP 2020.
