Technical in<strong>for</strong>mation about the delivery<br />
Valmet’s total scope <strong>of</strong> delivery includes a<br />
Valmet DNA Automation System, safety-related<br />
systems, Valmet DNA Machine Monitoring,<br />
training simulator, in<strong>for</strong>mation<br />
management calculation applications <strong>for</strong><br />
both emissions monitoring <strong>and</strong> reporting<br />
as well as monitoring the key per<strong>for</strong>mance<br />
indicators (KPI) <strong>of</strong> the boiler <strong>and</strong> the entire<br />
plant.<br />
The automation system will be equipped<br />
with a Valmet DNA User Interface (DNA<br />
UI) that adapts the shown in<strong>for</strong>mation<br />
based on the needs <strong>of</strong> various users <strong>and</strong><br />
user groups. Relevant in<strong>for</strong>mation is delivered<br />
in visual, well-structured, easy-to-underst<strong>and</strong><br />
dashboards, process <strong>and</strong> sub-process<br />
views, allowing the users <strong>of</strong> the automation<br />
system to control the process better.<br />
Built with the latest web technologies,<br />
DNA UI comes with a secure web-based<br />
access that enables the plant teams to access<br />
relevant in<strong>for</strong>mation whenever they<br />
need it, regardless <strong>of</strong> their location.<br />
The new boiler plant 3 will replace the<br />
existing boiler plant 2 <strong>and</strong> re-use some <strong>of</strong><br />
its process parts, which all are already<br />
based on Valmet DNA.<br />

Rolls-Royce builds new fuel cell<br />
demonstrator to ensure<br />
electricity supplies<br />
• Alternative fuels <strong>and</strong> fuel cells <strong>for</strong><br />
carbon-neutral mtu solutions<br />
• 250 kW demonstrator from Rolls-Royce<br />
testing st<strong>and</strong>by, prime <strong>and</strong> UPS power<br />
supply functionality<br />
(r-r) Another new technology – the hydrogen<br />
fuel cell – is currently making in-roads<br />
at the Friedrichshafen plant <strong>of</strong> Rolls-Royce‘s<br />
Power Systems division where a 250<br />
kW demonstrator is in the process <strong>of</strong> being<br />
set up to test future zero-carbon energy<br />
systems <strong>and</strong> present these to customers.<br />
„We firmly believe that fuel cell technology<br />
is set to make a huge contribution to a successful<br />
energy turnaround. That‘s why<br />
Rolls-Royce sees it as its mission to assume<br />
a pioneering role in fuel cell applications,“<br />
said Andreas Schell, CEO <strong>of</strong> Rolls-Royce<br />
Power Systems. „Fuel cells shall <strong>for</strong>m an<br />
elementary part <strong>of</strong> our product portfolio<br />
<strong>for</strong> sustainable solutions.“<br />
Why fuel cells? Fuel cells have very high<br />
efficiency levels when generating electricity<br />
from hydrogen <strong>and</strong> oxygen. When run<br />
on pure hydrogen, they give <strong>of</strong>f zero emissions<br />
– only water vapor – as well as being<br />
low-noise, low-maintenance, <strong>and</strong> vibration-free.<br />
“The greatest benefit is when<br />
they are run on regeneratively produced<br />
hydrogen because this enables polluting<br />
<strong>and</strong> climate-damaging gas emissions to be<br />
fully eliminated. This gives fuel cells a<br />
huge potential to become a major technology<br />
<strong>for</strong> decarbonizing propulsion <strong>and</strong> electrical<br />
power supply systems,” added Dr.<br />
Peter Riegger, Vice President Rolls-Royce<br />
PowerLab.<br />
Much has already happened at Rolls-<br />
Royce Power Systems‘ Friedrichshafen<br />
Plant 1 in recent months, with the complex<br />
hydrogen infrastructure – which requires a<br />
lot <strong>of</strong> investment – now installed <strong>and</strong> the<br />
container all set up complete with its four<br />
low-temperature PEM fuel cell modules.<br />
Indeed, this took quite a lot <strong>of</strong> work by engineers<br />
across a variety <strong>of</strong> sites. Designed<br />
at the company‘s plants in Ruhstorf (Bavaria)<br />
<strong>and</strong> Friedrichshafen, safety reasons dictate<br />
the container has two separate compartments<br />
<strong>for</strong> fuel cells <strong>and</strong> batteries, plus<br />
a host <strong>of</strong> power electronics. The control<br />
system has now been fully refined, cooling<br />
<strong>and</strong> air conditioning are on the ro<strong>of</strong>, <strong>and</strong> a<br />
rack system enables simple maintenance,<br />
allowing individual system modules to be<br />
replaced as required.<br />
The energy systems using fuel cell modules<br />
from the automotive sector have been<br />
put through their paces on the test st<strong>and</strong>,<br />
<strong>and</strong> Rolls-Royce engineers are more than<br />
happy with the results: “Power flexing<br />
characteristics <strong>and</strong> per<strong>for</strong>mance are excellent,<br />
<strong>and</strong> as expected there are no vibrations<br />
or no loud noises”, explained Dr. Peter<br />
Riegger. The next step is to connect all<br />
four demo modules together in the container<br />
<strong>and</strong> hook up the batteries <strong>and</strong> power<br />
circuit. Commissioning is slated <strong>for</strong> the second<br />
half <strong>of</strong> <strong>2021</strong>.<br />
The demonstrator will be used <strong>for</strong> test<br />
purposes, <strong>and</strong> to show interested parties<br />
which applications the system is suitable<br />
<strong>for</strong>. These include st<strong>and</strong>by power, prime<br />
power, uninterruptible power supplies<br />
(UPS) <strong>and</strong> black start capability, allowing<br />
the system to be started from scratch without<br />
a mains connection. The system consists<br />
<strong>of</strong> fuel cell modules, batteries, fire protection,<br />
air conditioning <strong>and</strong> safety systems,<br />
cooling, gas supply <strong>and</strong> automation.<br />

E.ON und RWTH verlängern<br />
Kooperationsvertrag<br />
• Erfolgreiche Arbeit des E.ON Energy<br />
Research Centers wird weiter gefördert<br />
(eon) E.ON wird die erfolgreiche Zusammenarbeit<br />
mit der RWTH Aachen <strong>for</strong>tführen<br />
und hat den bestehenden Kooperationsvertrag<br />
um weitere fünf Jahre verlängert.<br />
Eine entsprechende Vereinbarung<br />
unterzeichneten am 23. Juni E.ON-Vorst<strong>and</strong>smitglied<br />
Dr. Karsten Wildberger und<br />
der Rektor der RWTH Aachen, Pr<strong>of</strong>essor<br />
Ulrich Rüdiger.<br />
Mit dem neuen Kooperationsvertrag werden<br />
wir insbesondere Forschungsprojekte<br />
in den Bereichen Energie- und Nachhaltigkeits<strong>for</strong>schung,<br />
Energiesystemanalyse und<br />
-optimierung, Smart Grids, Energiespeicherung,<br />
Energieeffizienz, Elektrifizierung<br />
und Digitalisierung fördern. Dabei konzentrieren<br />
wir uns auf das E.ON Energy Research<br />
Center der RWTH Aachen (E.ON<br />
ERC), aber auch weitere Institute der Aachener<br />
Hochschule können und sollen eingebunden<br />
werden, erklärte Dr. Wildberger<br />
anlässlich der Vertragsunterzeichnung.<br />
Das E.ON ERC ist aus einer öffentlich-privaten<br />
Partnerschaft zwischen E.ON und<br />
der RWTH Aachen entst<strong>and</strong>en und setzt<br />
seit seiner Gründung im Jahr 2006 Maßstäbe<br />
in der interdisziplinären und vernetzten<br />
Energie<strong>for</strong>schung. E.ON wird in den<br />
kommenden fünf Jahren gemeinsame Forschungsprojekte<br />
mit einer Gesamtsumme<br />
von zehn Millionen Euro finanzieren. Hinzu<br />
kommen jährlich bis zu einer halben<br />
Million Euro zur Finanzierung von gemeinnützigen<br />
Projekten. In vielen Fällen werden<br />
auch die Ergebnisse der E.ON-Forschungsprojekte<br />
der Allgemeinheit zur<br />
Verfügung gestellt.<br />
Auch RWTH-Rektor Pr<strong>of</strong>essor Rüdiger<br />
zeigte sich sehr zufrieden mit der bisherigen<br />
Zusammenarbeit und freut sich auf<br />
fünf weitere erfolgreiche Jahre. Gemeinsam<br />
mit E.ON ist die RWTH seit 15 Jahren<br />
erfolgreich dabei, einen signifikanten Beitrag<br />
zur Energiewende zu leisten. Die Zusammenarbeit<br />
zeigt, welchen Impact wir<br />
als Hochschule im Netzwerk mit unseren<br />
Partnerinnen und Partnern leisten können.<br />
Mit E.ON verbindet uns eine starke Kooperation,<br />
die wir nun für die weitere erfolgreiche<br />
Gestaltung der Energiewende einsetzen<br />
werden.<br />
