Siemens Energy has been a leading supplier for
Electrification, Automation, and Digitalization solutions in the pulp
and paper industry for decades, is well connected in the landscape
of the global pulp and paper community, and therefore is a perfect
match for the add on of Power2X or eFuel projects, such as Liquid
Wind, into existing or new pulp and paper mills. Beyond this,
Siemens Energy is also implementing for the Liquid Wind project
the same Automation System, PCS7, the same drives, motors,
transformers, switchgears, and other electrification equipment as
has been used for years in countless pulp and paper mills around
the world. Also, COMOS will play a significant role as the backbone
of the entire Liquid Wind approach: implementing the Data Digital
Twin, SIMIT, and other simulation tools, will help to generate the
Process Digital Twin for the entire production chain of eMethanol. In
addition, a Digitalization toolbox will prepare the production facilities
for Autonomous Operations and Predictive/Remote maintenance
services.
Global roll-out of a model project
Liquid Wind, a Swedish power-to-fuel development
company, is currently planning the worldwide first large-scale
industrial roll-out of eMethanol production facilities. The first plants
will be built in Sweden, with additional plans to roll out the so-called
Flagship facilities in Europe and on a global scale, in partnership
with pulp and paper mills and CHP plants. The eMethanol produced
can be used to power all kinds of ships, and replace marine fuel oil.
Ten Flagships, with an annual production volume of a
minimum 50,000 metric tons of eMethanol each are to be built
by 2030. The company is planning to scale rapidly, targeting the
development and implementation of 500 plants worldwide by 2050.
The production facilities will use Siemens Energy’s Electrolyzer of
the newest generation, Silyzer 300, which is highly adaptive and
matching the requirements of the specific value chains.
This scaling is made possible thanks to a standardized and
modular facility model, based on the latest digitalization technology,
for the efficient replication of eMethanol facilities. The entire planning
and integration are carried out with the help of licensing, a so-called
Digital Twin, for data (COMOS), process and operations, which is
also provided by the Siemens Ecosystem. This means that all plants
can be planned, tested, and efficiently operated via Digital Twin
implementations. This offers great development opportunities for
scaling up in countries that are rich in renewable energy and, with
the synthesis from hydrogen and CO2, meet the growing demand for
green methanol.

Closed production cycles
Liquid Wind’s first eMethanol plant, FlagshipONE, will be co-located
with a combined heat and power plant (CHP) from Övik Energy
in Örnköldsvik, north-east Sweden, making use of biogenic CO2,
sustainable energy, and other utilities. The biomass-based flue
gases will form the green raw material for a carbon neutral fuel. In
the process, the CO2 for the methanol synthesis is captured from
the plant’s biomass-based flue gas. The purified water is used
for the hydrogen electrolysis, as is the water produced as a byproduct during the methanol synthesis. The waste heat is used to
concentrate the CO2.
The pulp and paper industry is an ideal industry partner for the
production of eMethanol for several reasons:
1.
The oxygen produced can be returned to the pulp mill
or CHP.
2.
Mills can use the on-site eMethanol to replace diesel
for trucks, fork lifters or caterpillars in their distribution
chain to further reduce CO2 emissions.
Each Liquid Wind facility will produce 50,000 tons of
eMethanol per year. To achieve this, 75 MW of renewable energy
from wind power will be used to produce green hydrogen, and
70,000 tons of industrial CO2 will be upcycled.
Four Siemens Silyzer 300 units will be used as Electrolyzers
for producing hydrogen. Siemens Energy is also responsible for the
plant-wide electrification, instrumentation & automation, including
engineering and services, as well as digitalization with Digital Twin
implementation, Industrial Internet of Things (IIoT), analytics, and AI
applications. Production from FlagshipONE in Sweden is scheduled
to start at the beginning of 2024.
