Klimakonference i Sønderborg: Skræmmende udsigter, men konstruktive klimaløsninger

CITIES havde sit eget spor på konferencen ’100 % Climate Neutrality’ på Alsion i Sønderborg tidligere på ugen, samtidig med at der var et fælles spor med over 250 deltagere fra hele Europa. Her præsenterede internationale forskere alarmerende facts om klimakrisen og de medfølgende konsekvenser.

Alligevel kunne gæsterne gå hjem med en god følelse i maven, for konferencens viste også, at vi allerede har mange af løsningerne på de klimaudfordringer verden står overfor, skriver arrangørerne – herunder CITIES-partner ProjectZero – i en pressemeddelelse.

Nogle af Europas skarpeste klimahjerner var i ugens løb samlet i Sønderborg for at stille skarpt på den galoperende klimakrise. Og selvom der blev malet med den helt sorte pensel, da fakta og konsekvenser blev præsenteret, så kunne både gæster og deltagere ved konference går derfra med et grønt håb for fremtiden – forskere præsenterede nemlig en række løsninger, som kan forebygge konsekvenserne og bl.a. forbedre energieffektiviteten og ressourceanvendelsen.

”Et godt eksempel er det, som vi med en lidt teknisk term, som vi kalder ’energy payback-time’, som er den tid, der går, før elementet har produceret den energi, det krævede at fremstille det. For organiske solceller, som vi forsker i her på SDU Sønderborg, er den tid nu helt nede på 3-4 uger, lyder det fra én af initiativtagerne og arrangørerne af konferencen”, fortæller leder af Mads Clausen Instituttet Horst-Günter Rubahn.

De unge gjorde deres indtog på konferencen
Konferencen bød på indlæg fra ledende forskere og repræsentanter fra projekterne CITIES, ActNow, RollFlex, PE:Region, Energibyerne.dk og det ambitiøse ungeklimaråd fra byer i både Danmark, Letland og Tyskland.

”Jeg vil i den sammenhæng gerne fremhæve ungeklimarådet, som bragte vitalitet ind i konferencen som vi ikke tidligere har oplevet, og så er det jo i bund og grund dem det handler om. Det er deres fremtid”, vi kæmper for, siger Horst-Günter Rubahn.

De unge indtog scenen i forbindelse med konferencens afsluttende paneldiskussion, som understregede, at de ikke ønsker at pege fingre eller kaste skyld på tidligere generationer, men i stedet vil række en udstrakt hånd frem og opfordre til tæt samarbejde og en fælles front mod de klimaproblemer verden står over for.

Dermed var tonen en anden end da ikonet og den svenske klimaaktivist, Greta Thunberg, indtog talerstolen ved FN’s klimatopmøde i New York i sidste måned og beskyldte verdens topledere for at have stjålet hendes drømme og barndom. Men alvoren og engagementet var den samme.

Tager konklusioner med til København
Sønderborgs ProjectZero vision, har til formål at reducere Sønderborg-områdets CO2-udledning til et rundt nul allerede i 2029 og samtidig skabe nye kompetencer og grønne jobs i virksomhederne.

Også ProjectZeros direktør, Peter Rathje, er som medarrangør glad og stolt over klimakonferencen og dens konklusioner:

”Sønderborg og partnerne i bl.a. CITIES, Energibyerne.dk og ActNow-projekterne har været i gang i mange år. Konferencen bekræftede, at ambitiøse klimamålsætninger bedst løses i tæt samarbejde med lokale interessenter og at byer/kommuner er de nye klima-omdrejningspunkter når der skal sættes turbo på klimaindsatserne”, siger Peter Rathje, adm. direktør, ProjectZero.

Peter Rathje opfordrer Regeringen og ministrene til at styrke dialogen med byerne af de relaterede forskningsprojekter, hvor universiteter og virksomheder allerede samarbejder om de nye løsninger til verdens byer/kommuner.

Derfor vil Peter Rathje tage konferencens konklusioner med til bl.a. København, når 96 af verdens ledende byer i uge 41 mødes for, i endnu større skala, at sætte actions på verdens klimaproblemer i forbindelse med ‘C40 Mayors Summit’.

Sønderborgs ProjectZero i Sveriges Radio

Sønderborg Kommune har siden 2007 reduceret CO2-udledningen med 38,3 procent. Ambitionen er at have reduceret udledningen af drivhusgasser med 75 procent i 2025, og at kommunen er CO2-neutral i 2029.

Resultatet og visionen trækker overskrifter i nabolandet, hvor Sveriges Radio har været på besøg og talt med tennisklubben (der sparer mange penge ved at holde temperaturen på 13-14 grader i hallen om vinteren og have LED-lamper), et supermarked, borgmesteren og ikke mindst Peter Rathje, der er administrerende direktør i CITIES’ partner ProjectZero.

Hør indslaget her

De overbevisende CO2-reduktioner er formet af ProjectZero, hvor man arbejder med alle energirelaterede CO2-udledninger, som knytter sig til energiproduktion og energiforbrug.

De første 10-12 år handlede det om spare energi, men nu handler det mere om at producere energi, fortæller Peter Rathje til Sveriges Radio. For kommunen vil gennem Roadmap2025 indlemme store mængder grøn energi fra sol, vind og biogas.

Borgmesteren fortæller, at det på bundlinjen har kostet kommunen penge, men at man samtidig har stimuleret erhvervslivet, så der er skabt nye virksomheder og job takket være klimambitionen, som derigennem sikrer skatteindtægter til kommunen.

I den kommende uge fra den 30. september til 2. oktober, finder den internationale klimakonference ’100% Climate Neutrality Conference’ sted i Sønderborg, hvor CITIES har sit eget spor tirsdag eftermiddag og onsdag formiddag. Se programmet herunder.

PROGRAMME FOR CITIES – Center for IT-Intelligent Energy Systems in Cities

Tuesday, 1 October
13:00 – 15:00

TRACK A1: CITIES – From Solutions to Scalable Solutions

The high densities of population, energy consumption, and energy and communications networks in cities offer a great potential for flexibility in the energy system. Cities account for 80% of global energy consumption and emissions, which makes the urban environment an ideal setting for energy systems integration research. 

CITIES is a project which pioneers research into fully integrated city energy systems, building shortterm operational models that feed longer term planning models, considering the spatiotemporal variations, interactions, dynamics and stochastics in the energy system.

The project involves leading position of European academia and industry. The conference programme will include a combination of speeches from the international project participants, European Lighthouse projects (SCC1-H2020) and industry partners in the CITIES project.

Summer school engineering the green transition

During a week, 44 young researchers got ‘hands-on’ experience with statistical modelling techniques for smart energy systems and intelligent energy savings, including calculating solar energy gain in buildings.

44 PhD students and postdocs mainly from universities in Europe have spent last week of August at DTU Compute to learn about smart energy systems and intelligent energy savings.

The summer school was arranged by the two centres CITIES, lead by DTU (including the Interreg supported project Smart Cities Accelerator (SCA) and researchers from DTU, Section for Dynamical Systems), and FME-ZEN, lead by NTNU in Norway in collaboration with IEA EBC Annexes 67 & 71.

During the summer school named ‘Time series analysis – with a focus on modelling and forecasting in energy systems’ the participants were introduced to statistical techniques that are particularly useful for data driven modelling of energy systems. As well as the use of the models for e.g. control.

Engineering the future

This year was only the second time for the summer school about smart energy systems and Professor Henrik Madsen was very happy with the number of participants.

“These are the PhD students and postdocs to help the world achieve the green transition. These are not people, who are close to retiring. They are the ones who need to be part of this process,” he says.

“It is fascinating that there are so many coming from universities and knowledge institutions around Europe, and with backgrounds from universities all over the world, to hear about what we can do and learn about the technologies, we use in SCA, FME-ZEN and CITIES,” Henrik Madsen says.

Modelling building thermal dynamics

During the course, the students learned about how CITIES, FME-ZEN and SCA work with intelligent energy savings using data to characterize the thermal performance of buildings. And how to identify the dynamics of the building.

This applies both in terms of being able to use the building as thermal energy storage, but also to be able to pinpoint the easiest achievable energy savings – thus where building refurbishment gives the most value.

The summer school alternated between lectures and exercises to get ‘hands-on’ experience with the technique – for example, to calculate solar energy gain in buildings, and how it affects the building.

This is a technology, that PhD student Christoffer Rasmussen and his colleagues from DTU Compute has developed. Christoffer Rasmussen was also one of the teachers at the summer school:

“Usually, the solar energy gain is said to be dependent on the sun’s radiation from the outside, but the usual data driven models assume that the solar gain is proportional to the solar irradiation and constant throughout the day. It is not, as the Earth is turning.”

“In our data driven models we have made the solar energy inflow dependent on the sun’s position in the sky, such that you can account for, for example, a large window area towards one corner of the Earth and shading trees toward another. The incident angle of the sun rays will also change during the day which affects the amount of irradiation entering the building. All this, and more, are we now capable of estimating only based time series measurements,” explains Christoffer Rasmussen.

During the course, participants have learnt how the statistical modelling techniques work fundamentally and how to implement it in grey-box models (combining a partial theoretical structure with data) and in this way model the solar heat gain in buildings.

“At the end of the day, you want a good model that can describe the building dynamics and forecast different scenarios. It can be used, for example, to control the heating system of the building; how does the temperature react if you turn off or turn on the heat? How can you reduce the cost of heating the building if the consumer has variable energy prices, while using more green energy and keeping the consumer happy and warm?” says Christoffer Rasmussen.

Happy participants

PhD student Nasibeh Saffari from URV – Rovira at Virgili University in Catalonia, Spain is one of the participants at the summer school.

Usually, she works with artificial intelligence in the pharmaceutical industry. She is here because her friends praised last years summer school.

“It is interesting to work with models and algorithms. I am here to expand my knowledge. It is hard because I work with something completely different at home in Spain, but I’ve learned a lot over the week,” she says.

Another participant, American Evan Alexander, who has an MBA from Duke University, works daily for Maersk’s digitization group in Copenhagen, where data is analyzed through a forecasting program to optimize Maersk’s shipping business.

“It has been great! This is the second year that I spend a week of my summer vacation at a summer school at DTU. I am here to learn new modelling techniques and update my knowledge. I definitely expect to do it again next year because I get a lot of knowledge back home,” says Evan Alexander.

After the course, the students submit a report on the exercises they work on at the summer school.

Professor Henrik Madsen awarded best Senior Presenter

Professor Henrik Madsen awarded best Senior Presenter

Earlier this week, Professor and Centre Leader at DTU Compute Henrik Madsen was awarded with the prize for the best Senior Presentation at the 5th International Conference on Smart Energy Systems in Copenhagen.

The presentation ’Perspective in Using Meter Data for Temperature Optimization’ was based on knowledge from the project CITIES, Smart Cities Accelerator, IDASC (Intelligent data-anvendelse i Smart Cities), Heat 4.0, and FED.

The presentation was so exciting and well communicated that Henrik Madsen won the prize of 1000 Euro sponsored by Kamstrup.

The nomination was justified by ”his (Henrik Madsens, red.) enthusiasm is still fully alive after all the years of experience. He keeps pushing the boundaries of control methods.”

Professor Henrik Madsen was very pleased and surprised by the award for his presentation.

The point of the theme in the presentation is that ‘data is gold’.

“With new meters and frequent meter readings we are finally at a stage where we can benefit from a next generation of tools for forecasting and control based on data-analytics and machine learning,” he says.

“We have demonstrated that this gives new possibilities for smart control of low temperature district heating. This new generation of district heating systems will pave for an acceleration of the green transitions with more efficient supply, better use of heat pumps and excess heat, and for unlocking the flexibility in DH systems needed for the fossil free energy system,” Henrik Madsen says.

Kamstrup is a world-leading supplier of intelligent energy and water metering solutions, so Henrik Madsen’s presentation resonated with the companys interest.

“Henrik’s presentation was an excellent example on the potential for increased digitalization in the DH industry. Temperature optimization based on real time data from smart meters makes it possible to operate the network closer to the limits and is thus a key enabler to lower the temperature levels in a DH system. And lower temperatures is a necessity for integrating large amounts of waste heat and renewable energy in the system,” says Steen Schelle Jensen, Head of Product Management – Solutions in Heat/Cooling Division at Kamstrup.

Hong Kong: CITIES model for Energy Systems in Smart Homes

Hong Kong: CITIES model for Energy Systems in Smart Homes

These weeks, Hong Kong is massive in the media due to major demonstrations and unrest in the city, but life in the city continues alongside. Last week, PhD student Hjørdis Amanda Schlüter and Professor John Bagterp, both affiliated with CITIES and the Smart Cities Accelerator at DTU Compute, attended the IEEE CCTA 2019 (Conference on Control Technology and Applications) in Hong Kong.

Here, on August 20, 2019 Hjørdis Amanda Schlüter presented a new model, EMPC, to manage the energy system in smart homes (Economic Model Predictive Control for Energy Systems in Smart Homes).

Here, the energy system basically consists of a stationary battery, photovoltaic solar cells on the roof, a heat pump for heating and an electric car where the battery has to be charged.

Using weather forecasts, thermal comfort and driving profiles, EMPC coordinates this energy system and its interaction with the external energy system by buying and selling electricity at prices announced in advance.

DTU Compute is not the first to present such a model. It has been done before, for example, by Stephen Boyd (Department of Electrical Engineering, Stanford University) in the article “Dynamic energy management with scenario-based robust MPC”. There he and his people focus on the software they have created to control a smart home energy system. ‘

“Our focus is on developing the simplest model we could think of. The model is so simple that it is easy to set up for others who do not know so much about the subject,” says Hjørdis Amanda Schlüter.

The conference was quite small and some of the participants did not show up due to the unrest in Hong Kong. Nevertheless, about 20 researchers and firms found their way to Hjørdis Amanda Schlüter’s presentation, and she got a lot of questions about the model.

The research continues with two graduate students who will be writing a thesis at John Bagterp this semester. They have to reproduce Hjørdis Amanda Schlüter’s results and then extend the model to a whole street instead of a single house.

Professor: Think energy communities on a large scale

The electricity generation of the future gets a new player – the prosumer. For example, a homeowner with solar cells on the roof, who both consumes power and produces and sells his surplus power. GridTech and the Ingeniøren have taken a closer look at the energy landscape of the future – and talked with Professor, Henrik Madsen.

Local energy communities, where, for example, homeowners produce, share and trade in energy, will take over part of the energy production in Denmark. Electricity companies have a monopoly on transmitting power to the grid, but new EU rules now pave the way for energy communities. Several smart city projects at DTU including both CITIES and the Interreg-supported Smart Cities Accelerator work with energy communities.

This week, Teknologiens Mediehus’ pro-media GridTech and newspaper Ingeniøren are reviewing a report from Energinet Elsystemansvar og Dansk Energi, about the future of the electricity system, including the presumptions about how energy communities will characterize the electricity grid.

Among others, the centre leader of CITIES and the technical manager of the Smart Cities Accelerator, Professor Henrik Madsen, is quoted.

“Energy communities should be a larger area where multi-supply is shared – water, district heating, electricity and gas. If the energy community is just a few people trading electricity with each other, it does not give the same flexibility. It is also an expensive way to do it …,” he says to GridTech.

The article is also in the newspaper Ingeniøren on Friday, August 16, 2019. If you are a member of IDA, you have access through your membership of the trade union. Otherwise, find the paper edition.
