GLOBAL MONITOR
Major Energy Storage Deal Announced.
Energy Dome, a global provider of long-duration
energy storage solutions that enable
renewable energy to be dispatchable, and
Ansaldo Energia, a leading international
power original equipment manufacturer
and service provider, signed a non-exclusive
license agreement to partner on the
commercialization of long-duration energy
storage facilities across Europe, the
Middle East, and Africa that will support
greater integration and use of renewable
energy on the grid. This partnership will
help accelerate the transition away from
fossil fuel power toward renewable energy
to meet climate goals. Energy Dome
will provide the " CO2
which uses carbon dioxide (CO2
Battery " technology,
), and Ansaldo
will provide equipment, engineering,
and construction of new grid-scale energy
storage to support the energy transition.
Energy Dome is nearing completion of its
first commercial CO2
Battery storage facility
in Sardinia, Italy. The company anticipates
it could build as many as 30 facilities
over the next five years in Italy, Germany,
the Middle East, and Africa. These facilities
will use Energy Dome's non-flammable,
non-toxic CO2
-based energy storage solution
to store and dispatch power. The
companies anticipate the deployment of
the first CO2
Batteries, including performance
guarantees, starting in 2023, with
Ansaldo Energia acting as EPC. Energy
Dome's technology uses carbon dioxide
and off-the-shelf components to charge
and discharge power from 4 hours to 24
hours, enabling renewables to serve as
fully dispatchable daily energy resources.
Energy Dome's CO2
Battery uses CO2
in
a closed-loop charge/discharge cycle as a
storage agent. Prior to charging, gaseous
CO2
is kept in a large dome structure. During
charging, electricity from the grid is
used to compress the CO2
into liquid form,
creating stored heat in the process. During
discharge, the liquid CO2
is evaporated using
the stored heat, expanded back into its
gaseous form, and used to drive a turbine
to generate electricity.
Tender Launched for Infrastructure
for Offshore Wind Projects. Poland's
PGE and Ørsted recently launched a
tender procedure for the construction
of onshore infrastructure necessary to
evacuate power from both stages of the
Baltica Offshore Wind Farm (OWF). Tender
results for the 1,498-MW Baltica 2
and 1,045.5-MW Baltica 3 projects are
planned to be announced by the end of
this year. Preparation for the construction
of the land part of the infrastructure
and its implementation will occur over
the next few years, in parallel with the
preparatory work at sea, according to an
executive with PGE. Tender results are
expected by the end of this year, with
the first construction on land expected in
the fourth quarter of 2023. The offshore
wind farm is expected to come online
in 2026, providing power to Poland. The
tender proceedings will be conducted by
PGE Baltica, and the contract with the
general contractor selected in the tender
will be signed jointly by PGE Baltica
and Ørsted, which form a joint venture
developing the Baltica OWF. The onshore
connection infrastructure for the wind
farm will be built in the vicinity of Osieki
Leborskie, in the Choczewo commune,
in the Wejherowo district in Pomerania.
Two adjacent land stations will be built
there, one for Baltica 2 and another for
Baltica 3. Construction includes the power
stations and power export cable lines
on land, along with access and internal
roads, water and sewage network for
the stations, and lighting and fencing. ■
