           Foreword

           Welcome to the 2020 ten-year Network
           Development Plan (NDP) published
           by Gas Networks Ireland.
           This document provides a view of how the gas
           network may develop over a ten-year period.
           It is based on current supply and demand for
           gas, as well as projections for gas consumption
           and development of infrastructure. The
           document follows a process of engagement and
           consultation, both internally and through informal
           consultation with key industry stakeholders.

     Introduction

     Key messages:
     The gas network currently consists of 2,477
     km of high pressure steel transmission
     pipelines and 12,044 km lower pressure
     polyethylene distribution pipelines.
     Natural gas is available in 21 counties and
     there are circa 700,000 users in Ireland.
     The Network Development Plan (NDP)
     provides a view of how the gas network may
     develop over a ten-year period. It is based on
     current supply and demand for gas, as well
     as projections for growth in gas consumption
     and development of infrastructure.

     Gas Networks Ireland, together with its

     Replacing diesel in HGVs and buses with CNG
     can deliver immediate emissions reductions,
     air quality improvement (by eliminating
     particulate matter) and noise reduction.
     CCS can capture up to 100% of the CO2
     emissions produced from the use of fossil
     fuels in electricity generation and industrial
     processes, significantly reducing the amount
     of carbon dioxide entering the atmosphere.
     Hydrogen may be stored indefinitely
     and may be used in heat, transport,
     industry or power generation.
     Gas Networks Ireland welcomes the strength of
     the ambition and the associated governance set
     out in the Climate Action Plan and recognises
     that Ireland must significantly increase its
     commitments to tacking climate disruption.

Gas Networks Ireland, together with
its parent company Ervia, published
“Vision 2050 – A Net Zero Carbon Gas
Network for Ireland”3 on the 3rd of
October 2019. Through a combination
of technologies, Gas Networks Ireland
sets out one potential pathway
to reducing Ireland’s total carbon
emissions by one third by creating a
net zero carbon gas network.

Vision 2050 outlines one potential
role that the gas network and key
technologies such as renewable gas,
compressed natural gas (CNG) for
transport, carbon capture and storage
(CCS) and hydrogen can play in tackling
climate change while also ensuring
that Ireland has a sustainable and
secure energy future. Vision 2050
demonstrates how the gas network
supports decarbonisation for domestic
customers, industrial users, transport,
agriculture and power generation.

Today, gas is used to generate
approximately 52% of Ireland’s
electricity. A move to achieving a 70%
renewable energy share in electricity
generation (RES-E), such as from
wind and solar, is planned by 2030                  Ireland has a secure energy supply at               CCS, meaning Ireland can continue to
as part of ambitious national climate               all times.                                          benefit from the reliability of the gas
