UFWA commenced its operations in Australia in 2008, to develop a portfolio of wind farms acquired
from a local developer.
The portfolio comprises 8 projects in 2 States:
NSW: Crookwell 2, Crookwell 3 and Paling Yards (Southern Tablelands)
VIC: Ryan Corner, Hawkesdale, Berrybank, Darlington and Tarrone (all in the SW district)
Currently the portfolio represents ~1,300MW of wind farms being developed, with one of them
(Crookwell 2, 91MW), already moving into construction mode.
On 18th August 2016, the ACT Government awarded Crookwell 2 Wind Farm a Feed-in Tariff
Entitlement as part of the ACT Next Generation Renewables Auction. It is expected that the wind
farm will commence commercial operation by late 2018, contributing to the 100% renewables target
for the Territory.
We are committed to a number of initiatives for Economic Development in the ACT. The key one for
the Academic Institutions and for the Industry of the ACT, is the Renewable Power to Gas initiative,
which is described in the rest of this presentation.

The challenge for
energy storage
7
Peak demand from the System will not necessarily match the Maximum Renewable Production
The challenge for energy storage
Wind and solar energy are naturally fluctuating
Solar generation shows a daily trend, with seasonal variation
Wind generation shows a more random behaviour
Current targets for renewable energy at a global scale, and specifically for the ACT, require an
increasingly important role of wind and solar energy.
The natural variability and intermittency of these sources will require solutions to balance the
generation with demand.

The challenge for energy storage
Energy storage technologies and properties

Stored energySource: Fraunhofer IWES - Solarfuel
Hydrogen and methane do not require a specific storage infrastructure as they can be directly
injected into the existing gas distribution grid that acts as the sink
Energy Storage with different discharge ranges, capacities and timeframes offer a solution that will
allow a higher penetration of variable renewable energy.
A combination of storage technologies would be required.
Hydrogen and Methane (natural gas), are forms of storage offering larger energy storage
capabilities and are potentially the most suitable for bulk energy storage.

Renewable Power to Gas
(ReP2G) technology

Renewable Power to Gas (ReP2G) technology
Concept
Methanation provides a double benefit: Energy storage plus CO2 reduction
ReP2G technology is a leading candidate to tackle the issues associated with the intermittency of
renewable energy power generation.
The ReP2G process links the electrical power grid to the gas grid by converting the electrical energy
to:
Hydrogen (H2) by water electrolysis for direct injection in the gas grid or conversion to;
Methane (CH4) by the reaction of H2 with an available source of carbon monoxide (CO) or carbon
dioxide (CO2). This process results in a substitute or synthetic natural gas (SNG) and offers
significant potential as a CO2 sink.

Renewable Power to Gas (ReP2G) technology
Electric and gas networks interconnection
The electricity and gas networks can become increasingly interconnected leading to a sustainable,
interconnected and smart energy grid
Other technologies can build upon ReP2G, adding value and increasing the sustainability of the
energy system

Renewable Power to Gas (ReP2G) technology
Advantages
ReP2G technology allows or facilitates:
• Increased renewable generation capacity.
• Avoided renewable curtailment.
• Absorption of reactive power.
• Reduced reserve power
• Reduced CO2
emissions.
• Increased value for transport and distribution assets.
• Creation of a new business: Production of synthetic gas/renewable heat.
• Decarbonising Gas.
• Reduced fuel imports
• Improved security of supply.
• Creation of jobs and wealth.
• Creation of a new industry: Production of synthetic fuels.
• Avoid investments in expensive storage facilities.
• Reduced CO2
emissions.

Renewable Power to Gas (ReP2G) technology
Our experience in Europe
CDPL’s parent company, GNF Group, has already conducted research and developed a number of
pioneering projects dealing with ReP2G technology and storage:
Sotavento
Collaborative project with the Regional Government of Galicia to
acquire knowledge on the technology and potential of H2 as
storage of renewable energy. This plant, the first of its type in
Europe, has a capacity of 288kW, achieving a H2 production
efficiency of 75% producing some 60 Nm3/h of gas.
Smart Green GasCollaborative project
investing improvements in
the process to up-grade
biogas to bio-methane for
injection in the gas network
or use as a transport fuel.

Spain and investigation
in a 15kW pilot plant.

General scope
To deliver the proposed energy storage paradigm, CDLP, ANU-ECI and ActewAGL are engaging to
carry out this initiative with the following goals:
Bring together academic institutions and the industry to integrate energy storage solutions with the
existing and future rooftop solar PV installations and other micro-grid infrastructure.
Invest in an appropriately sized ReP2G pilot plant, envisaged to be in the range of 100-200 kW on
an ACT site to support the applicable research and test program, whose results will provide
knowledge about the technical and economic feasibility of the ReP2G systems.
Assess the commercial potential of the Power2Gas technology.
Ultimately, seek to create a new sector within the renewable energy industry reaching beyond the
ACT that will create long-term jobs and economic benefits as a result of rolling out commercial
products.
CDLP will provide seed funding for the ReP2G project valued at $1.25M. Also as a part of the transfer
activities, we will transfer knowledge and experience valued in $30M.
Additionally, a significant part of the funding that CDLP will provide to the ACT tertiary collaboration &
research partnership with the ANU, valued at $1.5 million over 20 years, will be oriented to the ReP2G
initiative and this provision will comprise of:
An annual scholarship of up to $25,000
Additional collaborative research funding of up to $50,000 per annum.
