COUNCIL IMPLEMENTING DECISION (EU) 2021/2058

of 23 November 2021

authorising Italy to apply a reduced rate of taxation to electricity supplied directly to vessels, other than private pleasure craft, at berth in a port

THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Council Directive 2003/96/EC of 27 October 2003 restructuring the Community framework for the taxation of energy products and electricity (1), and in particular Article 19 thereof,

Having regard to the proposal from the European Commission,

Whereas:

| (1) | In its letter of 14 September 2020, Italy, in accordance with the procedure laid down in Article 19 of Directive 2003/96/EC, requested authorisation to apply a reduced rate of taxation to electricity supplied directly to maritime and inland waterway vessels, other than private pleasure craft, at berth in a port (‘shore-side electricity’). In its letter of 12 May 2021, Italy provided additional information. |

(1)

In its letter of 14 September 2020, Italy, in accordance with the procedure laid down in Article 19 of Directive 2003/96/EC, requested authorisation to apply a reduced rate of taxation to electricity supplied directly to maritime and inland waterway vessels, other than private pleasure craft, at berth in a port (‘shore-side electricity’). In its letter of 12 May 2021, Italy provided additional information.

| (2) | Through the reduced rate of taxation, Italy aims to promote the use of shore-side electricity. The use of such electricity is considered to be an environmentally less harmful way of satisfying the electricity needs of vessels at berth in a port than the burning of bunker fuels by those vessels. |

(2)

Through the reduced rate of taxation, Italy aims to promote the use of shore-side electricity. The use of such electricity is considered to be an environmentally less harmful way of satisfying the electricity needs of vessels at berth in a port than the burning of bunker fuels by those vessels.

| (3) | Insofar as the use of shore-side electricity avoids emissions of air pollutants resulting from the burning of bunker fuels by vessels at berth in a port, it improves local air quality in port cities. The reduced rate of taxation to shore-side electricity is therefore expected to contribute to the environmental, health and climate policy objectives of the Union. |

The reduced rate of taxation to shore-side electricity is therefore expected to contribute to the environmental, health and climate policy objectives of the Union.

| (4) | Allowing Italy to apply a reduced rate of taxation to shore-side electricity does not go beyond what is necessary to increase the use of such electricity since on-board generation of electricity will remain a more competitive alternative in most cases. For the same reason, and because of the current relatively low degree of market penetration of the technology, the application of a reduced rate of taxation to shore-side electricity is unlikely to lead to significant distortions in competition during the period of application of that rate of taxation and will thus not negatively affect the proper functioning of the internal market. |

| (5) | In order to enable port and ship operators, as well as distributors and redistributors of electricity, to continue promoting the use of shore-side electricity, it is appropriate to authorise Italy to apply a reduced rate of taxation to shore-side electricity. |

In order to enable port and ship operators, as well as distributors and redistributors of electricity, to continue promoting the use of shore-side electricity, it is appropriate to authorise Italy to apply a reduced rate of taxation to shore-side electricity.

| (6) | In accordance with Article 19(2) of Directive 2003/96/EC, authorisations granted under the procedure laid down in Article 19(1) of that Directive are to be strictly limited in time. In order to ensure that the authorisation period is sufficiently long so as not to discourage relevant economic operators from making the necessary investments, it is appropriate to grant the requested authorisation for 6 years from 1 January 2022. However, the authorisation should cease to apply from the date of application of any general provisions on tax advantages for shore-side electricity adopted by the Council under Article 113 or any other relevant provision of the Treaty on the Functioning of the European Union, should such provisions become applicable prior to 31 December 2027. |

This Decision is without prejudice to the application of Union rules regarding State aid,

HAS ADOPTED THIS DECISION:

Article 1

Italy is authorised to apply a reduced rate of taxation to electricity supplied directly to maritime and inland waterway vessels, other than private pleasure craft, at berth in a port (‘shore-side electricity’), provided that the minimum levels of taxation referred to in Article 10(1) of Directive 2003/96/EC are respected.

Article 2

This Decision shall apply from 1 January 2022 until 31 December 2027.

However, should the Council, acting on the basis of Article 113 or any other relevant provision of the Treaty on the Functioning of the European Union, provide for general provisions on tax advantages for shore-side electricity, this Decision shall cease to apply on the day on which those general provisions become applicable.

Article 3

This Decision is addressed to the Italian Republic.

ANNEX 4

Test conditions and procedures for the assessment of post-crash hydrogen fuel system integrity

1.   Purpose

Determination of compliance with the requirements of paragraph 5.2.1 of this Regulation.

2.   Definitions

For the purposes of this annex:

| 2.1. | 'Enclosed spaces' indicates the special volumes within the vehicle (or the vehicle outline across openings) that are external to the hydrogen system (storage system, fuel cell system and fuel flow management system) and its housings (if any) where hydrogen may accumulate (and thereby pose a hazard), such as the passenger compartment, luggage compartment and space under the hood. |
| --- | --- |

2.1.

| 2.2. | 'Luggage compartment' is the space in the vehicle for luggage and/or goods accommodation, bounded by the roof, hood, floor, side walls, being separated from the passenger compartment by the front bulkhead or the rear bulkhead. |
| --- | --- |

2.2.

| 2.3. | 'Nominal working pressure (NWP)' is the gauge pressure that characterizes typical operation of a system. For compressed hydrogen gas containers, NWP is the settled pressure of compressed gas in a fully fuelled container or storage system at a uniform temperature of 15 °C. |
| --- | --- |

2.3.

3.   Preparation, instrumentation and test conditions

| 3.1. | Compressed hydrogen storage systems and downstream piping |
| --- | --- |

3.1.

| 3.1.1. | Prior to conducting the crash test, instrumentation is installed in the hydrogen storage system to perform the required pressure and temperature measurements if the standard vehicle does not already possess instrumentation with the required accuracy. |
| --- | --- |

3.1.1.

| 3.1.2. | The hydrogen storage system is then purged, if necessary, following manufacturer directions to remove impurities from the container before filling the storage system with compressed hydrogen or helium gas. Since the storage system pressure varies with temperature, the targeted fill pressure is a function of the temperature. The target pressure shall be determined from the following equation:
  Ptarget = NWP × (273 + T0) / 288
  where NWP is the nominal working pressure (MPa), T0 is the ambient temperature to which the storage system is expected to settle, and Ptarget is the targeted fill pressure after the temperature settles. |
| --- | --- |

3.1.2.

Ptarget = NWP × (273 + T0) / 288

where NWP is the nominal working pressure (MPa), T0 is the ambient temperature to which the storage system is expected to settle, and Ptarget is the targeted fill pressure after the temperature settles.

| 3.1.3. | The container is filled to a minimum of 95 per cent of the targeted fill pressure and allowed to settle (stabilize) prior to conducting the crash test. |
| --- | --- |

3.1.3.

| 3.1.4. | The main stop valve and shut-off valves for hydrogen gas, located in the downstream hydrogen gas piping, are in normal driving condition immediately prior to the impact. |
| --- | --- |

3.1.4.

| 3.2. | Enclosed spaces |
| --- | --- |

3.2.

| 3.2.1. | Sensors are selected to measure either the build-up of the hydrogen or helium gas or the reduction in oxygen (due to displacement of air by leaking hydrogen/helium). |
| --- | --- |

3.2.1.

| 3.2.2. | Sensors are calibrated to traceable references to ensure an accuracy of ±5 per cent at the targeted criteria of 4 per cent hydrogen or 3 per cent helium by volume in air, and a full scale measurement capability of at least 25 per cent above the target criteria. The sensor shall be capable of a 90 per cent response to a full scale change in concentration within 10 seconds. |
| --- | --- |

3.2.2.

| 3.2.3. | Prior to the crash impact, the sensors are located in the passenger and luggage compartments of the vehicle as follows:






  (a) | At a distance within 250 mm of the headliner above the driver's seat or near the top centre of the passenger compartment; |
| --- | --- | --- |

3.2.3.

(a)

At a distance within 250 mm of the headliner above the driver's seat or near the top centre of the passenger compartment;

| (b) | At a distance within 250 mm of the floor in front of the rear (or rear most) seat in the passenger compartment; and |
| --- | --- |

(b)

At a distance within 250 mm of the floor in front of the rear (or rear most) seat in the passenger compartment; and

| (c) | At a distance within 100 mm of the top of luggage compartments inside the vehicle that are not directly affected by the particular crash impact to be conducted. |
| --- | --- |

(c)

At a distance within 100 mm of the top of luggage compartments inside the vehicle that are not directly affected by the particular crash impact to be conducted.

| 3.2.4. | The sensors are securely mounted on the vehicle structure or seats and protected for the planned crash test from debris, air bag exhaust gas and projectiles. The measurements following the crash are recorded by instruments located in the vehicle or by remote transmission. |
| --- | --- |

3.2.4.

| 3.2.5. | The test may be conducted either outdoors in an area protected from the wind and possible solar effects, or indoors in a space that is large enough or ventilated to prevent the build-up of hydrogen to more than 10 per cent of the targeted criteria in the passenger and luggage compartments. |
| --- | --- |

3.2.5.

4.   Post-crash leak test measurement for a compressed hydrogen storage system filled with compressed hydrogen

| 4.1. | The hydrogen gas pressure, P0 (MPa), and temperature, T0 (°C), are measured immediately before the impact and then at a time interval, Δt (min), after the impact. |
| --- | --- |

4.1.

| 4.1.1. | The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at least 60 minutes. |
| --- | --- |

4.1.1.

| 4.1.2. | The time interval, Δt shall be increased if necessary in order to accommodate measurement accuracy for a storage system with a large volume operating up to 70MPa; in that case, Δt can be calculated from the following formula:
  Δt = VCHSS × NWP /1 000 × ((-0,027 × NWP +4) × Rs – 0,21) -1,7 × Rs

  where Rs = Ps / NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed hydrogen storage system (L), and Δt is the time interval (min). |
| --- | --- |

4.1.2.

Δt = VCHSS × NWP /1 000 × ((-0,027 × NWP +4) × Rs – 0,21) -1,7 × Rs

where Rs = Ps / NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed hydrogen storage system (L), and Δt is the time interval (min).

| 4.1.3. | If the calculated value of Δt is less than 60 minutes, Δt is set to 60 minutes. |
| --- | --- |

4.1.3.

| 4.2. | The initial mass of hydrogen in the storage system can be calculated as follows:
  P0′ = P0 × 288 / (273 + T0)
  ρ0′ = –0,0027 × (P0′)2 + 0,75 × P0′ + 0,5789
  M0 = ρ0′ × VCHSS |
| --- | --- |

4.2.

P0′ = P0 × 288 / (273 + T0)

ρ0′ = –0,0027 × (P0′)2 + 0,75 × P0′ + 0,5789

M0 = ρ0′ × VCHSS

| 4.3. | Correspondingly, the final mass of hydrogen in the storage system, Mf, at the end of the time interval, Δt, can be calculated as follows:
  Pf′ = Pf × 288 / (273 + Tf)
  ρf′ = –0,0027 × (Pf′)2 + 0,75 × Pf′ + 0,5789
  Mf = ρf′ × VCHSS

  where Pf is the measured final pressure (MPa) at the end of the time interval, and Tf is the measured final temperature (°C). |
| --- | --- |

4.3.

Pf′ = Pf × 288 / (273 + Tf)

ρf′ = –0,0027 × (Pf′)2 + 0,75 × Pf′ + 0,5789

Mf = ρf′ × VCHSS

where Pf is the measured final pressure (MPa) at the end of the time interval, and Tf is the measured final temperature (°C).

| 4.4. | The average hydrogen flow rate over the time interval is therefore:
  VH2 = (Mf-M0) / Δt × 22,41 / 2,016 × (Ptarget /P0)
  where VH2 is the average volumetric flow rate (NL/min) over the time interval and the term (Ptarget/P0) is used to compensate for differences between the measured initial pressure (P0) and the targeted fill pressure (Ptarget). |
| --- | --- |

4.4.

VH2 = (Mf-M0) / Δt × 22,41 / 2,016 × (Ptarget /P0)

where VH2 is the average volumetric flow rate (NL/min) over the time interval and the term (Ptarget/P0) is used to compensate for differences between the measured initial pressure (P0) and the targeted fill pressure (Ptarget).

5.   Post-crash leak test measurement for a compressed hydrogen storage system filled with compressed helium

| 5.1. | The helium gas pressure, P0 (MPa), and temperature T0 (°C), are measured immediately before the impact and then at a predetermined time interval after the impact. |
| --- | --- |

5.1.

| 5.1.1. | The time interval, Δt, starts when the vehicle comes to rest after the impact and continues for at least 60 minutes. |
| --- | --- |

5.1.1.

| 5.1.2. | The time interval, Δt, shall be increased, if necessary, in order to accommodate measurement accuracy for a storage system with a large volume operating up to 70 MPa; in that case, Δt can be calculated from the following equation:
  Δt = VCHSS × NWP /1 000 × ((-0,028 × NWP +5,5) × Rs – 0,3) – 2,6 × Rs

  where Rs = Ps / NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed hydrogen storage system (L), and Δt is the time interval (min). |
| --- | --- |

5.1.2.

Δt = VCHSS × NWP /1 000 × ((-0,028 × NWP +5,5) × Rs – 0,3) – 2,6 × Rs

where Rs = Ps / NWP, Ps is the pressure range of the pressure sensor (MPa), NWP is the Nominal Working Pressure (MPa), VCHSS is the volume of the compressed hydrogen storage system (L), and Δt is the time interval (min).

ANNEX 5

Test procedures for the vehicles equipped with electric power train

This annex describes test procedures to demonstrate compliance to the electrical safety requirements of paragraph 5.2.2 of this Regulation.

1.

If a high voltage disconnect function is used, measurements are to be taken from both sides of the device performing the disconnect function. However, if the high voltage disconnect is integral to the REESS or the energy conversion system and the high-voltage bus of the REESS or the energy conversion system is protected according to protection degree IPXXB following the impact test, measurements may only be taken between the device performing the disconnect function and the electrical loads.

The voltmeter used in this test shall measure DC values and have an internal resistance of at least 10 MΩ.

2.

After the impact test, determine the high voltage bus voltages (Ub, U1, U2) (see Figure 1 below).

The voltage measurement shall be made not earlier than 10 seconds, but, not later than 60 seconds after the impact.

This procedure is not applicable if the test is performed under the condition where the electric power train is not energized.

Prior to the impact a switch S1 and a known discharge resistor Re is connected in parallel to the relevant capacitance (ref. Figure 2 below).

| (a) | Not earlier than 10 seconds and not later than 60 seconds after the impact the switch S1 shall be closed while the voltage Ub and the current Ie are measured and recorded. The product of the voltage Ub and the current Ie shall be integrated over the period of time, starting from the moment when the switch S1 is closed (tc) until the voltage Ub falls below the high voltage threshold of 60 V DC (th). The resulting integration equals the Total Energy (TE) in joules. |

| (c) | When U1 and U2 (see Figure 1 above) are measured at a point in time between 10 seconds and 60 seconds after the impact and the capacitances of the Y-capacitors (Cy1, Cy2) are specified by the manufacturer, Total Energy (TEy1, TEy2) shall be calculated according to the following formulas:
  TEy1 = 0,5 × Cy1 × U1

TEy1 = 0,5 × Cy1 × U1

Following the vehicle impact test any parts surrounding the high voltage components shall be, without the use of tools, opened, disassembled or removed. All remaining surrounding parts shall be considered part of the physical protection.

The jointed test finger described in Figure 3 shall be inserted into any gaps or openings of the physical protection with a test force of 10 N ± 10 per cent for electrical safety assessment. If partial or full penetration into the physical protection by the jointed test finger occurs, the jointed test finger shall be placed in every position as specified below.

Starting from the straight position, both joints of the test finger shall be rotated progressively through an angle of up to 90° with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.

Internal electrical protection barriers are considered part of the enclosure.

If appropriate a low-voltage supply (of not less than 40 V and not more than 50 V) in series with a suitable lamp should be connected, between the jointed test finger and high voltage live parts inside the electrical protection barrier or enclosure.

Both joints shall permit movement in the same plane and the same direction through an angle of 90° with a 0 to +10° tolerance.

The requirements of paragraph 5.2.2.1.3 of this Regulation are met if the jointed test finger described in Figure 3, is unable to contact high voltage live parts.

If necessary, a mirror or a fiberscope may be used to inspect whether the jointed test finger touches the high voltage buses.

If this requirement is verified by a signal circuit between the jointed test finger and high voltage live parts, the lamp shall not light.

All measurements for calculating voltage(s) and electrical isolation are made after a minimum of 10 s after the impact.

| 5.2. | Measurement method
  The isolation resistance measurement is conducted by selecting an appropriate measurement method from among those listed in paragraphs 5.2.1 to 5.2.2 of this annex, depending on the electrical charge of the live parts or the isolation resistance.
  The range of the electrical circuit to be measured is clarified in advance, using electrical circuit diagrams. If the high voltage buses are conductively isolated from each other, isolation resistance shall be measured for each electrical circuit.
  Moreover, modifications necessary for measuring the isolation resistance may be carried out, such as removal of the cover in order to reach the live parts, drawing of measurement lines and change in software.
  In cases where the measured values are not stable due to the operation of the on-board isolation resistance monitoring system, necessary modifications for conducting the measurement may be carried out by stopping the operation of the device concerned or by removing it. Furthermore, when the device is removed, a set of drawings will be used to prove that the isolation resistance between the live parts and the electrical chassis remains unchanged.
  These modifications shall not influence the test results.
  Utmost care shall be exercised to avoid short circuit and electric shock since this confirmation might require direct operations of the high-voltage circuit. |
