Energy Modelling Lab has joined TEN21, a collaboration platform supporting district energy decarbonization. We are organized by the Swedish Environmental Research Institute (IVL) as a collaboration between experts across the district energy value chain. The name reflects our focus: Thermal Energy Networks for 21 Degrees of Indoor Comfort, TEN21.

Heating and cooling of buildings make up for a substantial part of energy consumption and total CO2 emissions. So far, only 20% of the heating and cooling provided to buildings in the European Union is produced by using green energy. In comparison, research has shown that 35% of the heating and cooling demand in the EU could be met by using waste heat, an asset with limited use today.

Advancing and supporting district energy decarbonization is therefore of great importance for reaching the goal of net-zero emissions.

Services

The team of TEN21 has the experience, network, and expertise to deliver the services of

  • Committing local authorities and stakeholders
  • Provide a holistic analysis of local district energy systems and resources
  • Identify least-cost and emission solutions using the most feasible technologies
  • Design roadmaps and identify replicable and bankable investment projects (we identify what to invest in, how large the installation should be, when in time it should be realized, and when existing assets should be retired)
  • Develop models for business and finance

Approach

We tailor the energy system model TIMES to analyze city-level district energy systems. Using the model enables us to process all data on energy production, consumption, and resources as well as data on buildings, industries, transportation, land use, and other of the studied locations. Based on the analysis, we study different scenarios and identify the optimal solutions.

Ancillary services costs in Sweden

illustration of ancillary services

We have been assigned by the Danish company Hybrid Greentech to develop a long-term forecast of ancillary services costs in Sweden. The forecast spans until 2050. At present, the electrification drive is inevitably leading to a surge in power demand. Consequently, a fundamental reconfiguration of our energy infrastructure is taking place. It must incorporate both intermittent renewables, flexible electricity demand, and the provision of ancillary services. 

So far, ancillary services have often been the unsung heroes of the power sector as these essential support systems ensure grid reliability. To make the forecast, we integrated and updated previous investigations into power production and demand. 

Potential innovative technologies

We took into consideration the production of green hydrogen in the Nordics. The flexibility of hydrogen production in the Nordics could be an important factor in the ancillary services market since a reduction of this production would most likely result in wider use of battery technologies. 

Potential innovative technologies could also have a high impact on the market for ancillary services. For example, the increasing number of electric vehicles means a large increase in power consumption. This increase, if managed flexibly, could potentially contain a total battery capacity of 250 GWh with a charging capacity of 50 GW. Such a capacity could support all the balancing requirements in all of Sweden if the potential is fully utilized. 

Electricity prices 

A long-term forecast of electricity production, consumption, and prices in Sweden was part of the analysis. In general, from 2020 to 2030 Sweden is expected to be a net exporter of electricity and from 2035 and onwards to be a net importer. Concerning consumption, an increase of about 80% in consumption from industry from 2020 to 2050 is expected. 

According to modelling results, the present price difference between the two Northern and the two Southern regions will decrease over time.

Early Action on Energy Efficiency

Energy Modelling Lab has contributed to the background study “The Value of Early Action on Energy Efficiency”. The study is focusing on buildings and industries. We identified key energy efficiency messages that we presented at the IEA Energy Efficiency Conference 2022 (see full presentation below). The conference took place in the Danish city of Sonderborg.

In collaboration with our partners, we examined the importance of early action on energy efficiency. We considered the costs of delayed progress. Furthermore, we looked into the benefits of achieving energy efficiency milestones on the way to reaching net zero emissions by 2050. The study was contracted by the International Energy Agency and financed by Danfoss.

Key findings on early action

Early action matters. A low energy efficiency pathway would increase final energy consumption by 39%. CO2 emissions increase by 16% if action is delayed by 10 years.

Energy efficiency is the most effective measure to quickly improve energy security and lower electricity prices.

Reduced air pollution in a global net zero emissions scenario can reduce the cost of global health impacts by almost €500 bn in 2030.

Water heaters provide the biggest shifting potential and thereby CO2 emission reductions. Due to high savings and load-shifting potential, water heaters should be one of the first products to be digitized.

In process industries maintenance and simple upgrade of process plants can save 5 to 10% with very short payback time.

The use of electromagnetic sources for process heat is in an early stage but holds promising potential for saving energy with a factor of 10 or more.

We used the IEA’s Net Zero Emissions by 2050 Scenario as a central focus and reference case for the analysis. Correspondingly, we focused on the implications and impacts of action within this decade, in all major energy-using regions globally.

Iconic portray of PtX

What could be the best locations for PtX plants in the Nordics? The answer to this question is one of the expected outcomes of the PtX Sector Coupling and LCA project. Energy Modelling Lab is collaborating with 13 partners. We are bringing our expertise in scenario analysis and advanced modelling to the project.

The PtX Sector Coupling and LCA project is part of the MissionGreenFuels partnership launched by the Danish Innovation Fund. The purpose of the project is twofold. The partners are working together on further developing existing energy systems and Life Cycle Assessment tools, methodologies, and models. The expected result is to create better ways to determine optimal ways of integrating PtX into the green transition.

Correspondingly, the partners are collaborating on using these models for assessments when it comes to defining the optimal locations of new PtX plants. This includes taking into consideration multiple factors such as grid capabilities, market forecasts, biomass, and carbon availability. Sector coupling and co-optimization of gas, electricity, hydrogen, and district heating are included as well. The models can generate different scenarios to be analyzed.

Our expertise

Energy Modelling Lab brings our expertise in using advanced mathematical models and modelling frameworks to the project, especially the use of the TIMES-NEU tool and model. Our assignment is to focus on describing sector coupling and potential synergies from the modelled scenarios. By analyzing the scenarios, we will clarify the optimal locations of PtX plants in Nordic countries in terms of cost-effectiveness.

Analysis of future energy market

Mix of solar parks and wind parks to produce green hydrogen
Mix of green energy production from sun and wind used for producing hydrogen

Energy Modelling Lab has made an analysis of the future energy market in Northern Europe that will develop under the green transition. The analysis was an assignment from COWI. It has been used as a reference in the report Roadmap to a Future, Danish hydrogen infrastructure, published by the CIP Foundation in May 2023.

The analysis focuses on Denmark, Norway, Sweden, Germany, Poland, Holland, Belgium, and UK. It probes the potential future markets of energy and fuels including PtX fuels from now on and until 2050.

Based on data from the Danish Energy Agency, the Danish production of electricity is expected to increase by almost 900 % by 2050. The increase is primarily due to offshore wind parks. It’s assumed that the offshore wind parks will be established in connection with planned “energy islands”; two to three in the North Sea and one in the Baltic Sea. Also, there are plans to establish electrolysis facilities and we assume they will be established on the energy islands.

Domestic demand

Domestic electricity demand is expected to remain almost constant due to energy-saving measures. But the overall expected increase could be about sevenfold from now on and until 2050, due to the planned expansion of PtX facilities. The bulk of the potential electricity production would thus be used for the production of green hydrogen for export. Denmark could potentially produce one-third of the total green hydrogen produced in the area, that our analysis covers.

The demand for hydrogen in Northern Europe is estimated to grow dramatically. According to the prognosis in the analysis, Holland, Belgium, and Germany will be the main purchasers. The estimated value of the potential, Danish green hydrogen export is 100 billion DKK pr. year.

Germany or Sweden

The prognosis is based on the assumption, that Germany’s capacity for hydrogen production will remain rather limited. This assumption relies on calculations showing that Danish offshore wind parks will produce slightly cheaper electricity than German facilities. Meanwhile, the likelihood that Germany will establish a large-scale production remains high.

An alternative scenario not included in the published analysis showed that Sweden could become the main purchaser of Danish-produced hydrogen by 2050. This is mainly due to estimates showing that production costs in Sweden are higher than in Denmark.

Energy Modelling Labs has updated the TIMES energy system model for the analysis. We developed it further to cover Northern Europe which resulted in developing the TIMES-NEU. The TIMES model is internationally recognized and developed by an IEA working group.

Energy Modelling Lab is supporting an informed local dialogue on green transition, presenting charts on future demand, feasibility of new solar panel facilities and wind farms and suggestions of how to meet the increase demand.

The demand for green electricity is set to increase sharply in the coming decades. To meet the daily needs of the citizens as well as the industries, production capacity will have to rise accordingly. But which solutions are suitable and feasible on the municipal level? During 2023, Energy Modelling Lab is participating in a series of meetings to support local dialogue on green transition.

The meetings are organized by the Danish Board of Technology. Both citizens, representatives from the local industries, and decision-makers are participating. In many places, heads of the local industries and businesses are very keen on being at the forefront of the green transition. Also, experience shows that many citizens are knowledgeable and willing to engage. Dialogue can increase the support for the changes that the green transition entails.

Planning for PtX facility

During meetings in Vordingborg Municipality, we presented charts explaining the estimated increase in the demand for green electricity. Due to the planned installation of a PtX facility on the harbor, the demand is expected to rise by more than six times by 2050.

We showed that this demand could be met by a mix of new solar power facilities, wind farms, and other green energy sources. A number of on-shore and off-shore wind farms are currently being planned. If all of them are installed, they could meet even a 12-fold rise in demand. It is expected that access to green energy will attract new industrial facilities on the harbor.

In the Municipality of Kalundborg, we also presented charts explaining the land use needed to produce 1 million MWh by different kinds of green energy production facilities. The areas needed are presented in comparison to the total area of Kalundborg:

Chart explaining the land-use needed to produce 1 MWh by different kinds of green energy production facilities. The areas needed are presented in comparison to the total area of Kalundborg

We also showed the estimated energy generated, if solar panels were installed on the roofs of all buildings larger than 500 m2: It would amount to 200.000 MWh or enough to meet 20% of the estimated demand in 2030.

A common obstacle to the installation of solar power facilities and wind farms is the lack of support by local landowners and future neighbors. Insights into the actual land use needed can help set realistic goals when planning for future energy facilities.

Udsigt over Vordingborg, hvor Energy Modelling Lab har afholdt grøn dialog om fremtidens energiforsyning

I Vordingborg forventes efterspørgslen på grøn strøm at stige i de kommende år. Det drejer sig dels om grøn strøm til at dække det almindelige forbrug til husholdninger, transport og erhverv, dels til det planlagte PtX-anlæg på erhvervshavnen. Hvor skal strømmen komme fra? Energy Modelling Lab har deltaget i et borgermøde om fremtidens grønne energi i Vordingborg, organiseret af Teknologirådet.

Hvad det almindelige forbrug angår, kan efterspørgslen gå hen og stige med 45% frem til 2050. For PtX-anlæggets vedkommende, så drejer det sig om mere end en seks-dobling frem til 2050. På to møder har vi præsenteret forskellige muligheder for at producere tilstrækkelig med grøn strøm.

Det har givet de fremmødte Vordingborg-borgere et godt grundlag for en dialog om grøn energi. En række fremtrædende, lokale erhvervsledere er på forkant med den grønne omstilling, og mange borgere er både engageret og vidende. Erfaringen viser, at dialog kan bane vejen for øget opbakning til de forandringer, omstillingen til grøn energi indebærer.

Vordingborg Kommunes Klima- og teknikudvalg forventer at vedtage en strategiske energiplan i løbet af efteråret 2023.

Sol og vind

Beregninger viser, at de allerede planlagte solcelle- og landvindsanlæg i Kommunen kan dække efterspørgslen til det almindelige forbrug til husholdninger, transport og erhverv. Det er også muligt at forsyne PtX-anlægget med energi fra havvind, som man kan se på nedenstående diagrammer. Der er indsendt en række ansøgninger til Energistyrelsen om at opføre havvind-projekter i områder omkring Vordingborg Kommune. Hvis anlæggene bliver opført, kan de forsyne PtX-anlægget.

Forbrug af arealer

Det er især de store industrivirksomheder, der får brug for store mængder grøn strøm. Det gælder blandt andre Gyproc, Novo Nordisk, Novozymes og Kalundborg Refinery. Der er mange spørgsmål at tage stilling til. Et af dem er, om Kalundborg Kommune skal gå efter at blive selvforsynende med grøn strøm eller satse på at få strøm udefra.

Et vigtigt grundvilkår er hvilke arealer, der kan benyttes. Grøn energiproduktion kræver forholdsvis store arealer. Energy Modelling Lab har udarbejdet et eksempel på, hvordan der kan produceres 1 million MWh om året i Kommunen. Kalundborg får muligvis brug for omkring 1,5 million MWh eller mere i 2050.

Vi præsenterede eksemplet på et borgermøde arrangeret af Teknologirådet. Vi viste blandt andet hvor mange hektar, de forskellige teknologier skal bruge for at producere 1 million MWh om året:

Diagram der viser arealforbruget til at producere grøn strøm med hhv. sol, havvind, landvind, træ, halm til energi og halm til biogas.

I eksemplet mixer vi, så 35 % af strømmen kommer fra havvind, 35 % fra landvind, 20 procent fra sol og de resterende 10 % fra træ og biogas. Der bliver der anvendt 9000 hektar i alt, heraf 1300 hektar til havvindmøller. Eksemplet indebærer, at der er produktion af grøn energi på omtrent 13 procent af Kalundborg Kommunes areal.

Præsentationen gav de fremmødte Kalundborg-borgere et godt grundlag for en dialog om grøn energi. En række fremtrædende, lokale erhvervsledere er på forkant med den grønne omstilling, og mange borgere er både engageret og vidende.

Viet Nam to reach net-zero emissions

Viet Nam is making headways in planning for the energy sector and is heading to reach net-zero emissions in 2050. Viet Nam Energy Outlook Report 2021  examined possible pathways for the development of the energy sector, and it featured a trajectory to reach this target for the first time.

One major finding was that a sustainable energy system will enable self-sufficiency. Another is that wind and solar energy are cheaper long-term solutions than coal and gas. At present, coal is the leading source of power.

Energy Modelling Lab is developing the scenarios that will be used in a new energy-system model for the Energy Outlook Report 2023. The model makes it possible for decision-makers and energy and power planners to identify the most cost-effective and feasible pathways to achieve a sustainable green transition.

Building DK-BioRes

MODELLING

The first step is to meet with our Vietnamese partners and agree on the questions to address, relevant analyses to undertake, and scenarios to design.

Energy Modelling Lab then redesigns and updates the modelling framework. We strengthen the representation of new decarbonization technologies and integrate relevant constraints.

SCENARIO ANALYSIS

The core scenarios focus on the realization of the net-zero target. They allow for a comprehensive investigation of optimal solutions. The results are then reflected in recommendations for policymaking.

The process fosters a wide consensus and understanding of Viet Nam’s energy challenges and opportunities in the mid-to long term.

REPORT

The Viet Nam Energy Outlook Report 2023 identifies the cost-optimized solutions that support Viet Nam’s energy system to become sustainable.

The Report allows for decision-makers to explore the system-wide implications of fulfilling targets by 2050. It also shows how Viet Nam can contribute to fulfilling the Paris Agreement on climate change.

Enhancing energy planning in Viet Nam

Energy Modelling Lab is enhancing energy planning in Viet Nam

Viet Nam is a regional manufactural hub and one of the most dynamic countries in East Asia, with the GDP annual growth rate averaging 6.2 per cent from 2000 until 2023. According to the analysis in the Viet Nam Energy Outlook Report 2021, electricity consumption will more than double in 2050 compared to 2020.

Viet Nam has pledged to reach the target of net-zero emissions by 2050. This means that the power system must meet more than 70 per cent of the total final energy demand with renewable energy-based electricity.

Energy Modelling Lab supports the endeavours to enhance energy planning in Viet Nam. We assist the Vietnamese authorities by building up their planning capacities concerning scenario-based, long-term modelling of the Vietnamese energy system. To this end, we are integrating an updated technology catalogue in the present energy system model and have included electricity storage solutions, P2X, nuclear technologies, optimal use of biomass, and carbon capture and storage.

Building DK-BioRes

MODELLING

Energy Modelling Lab updates the technology catalogue that is integrated into the present energy system model.

The catalogue includes decarbonisation technologies that are not yet being used and describes costs and relevant technical parameters.

ANALYSIS

The catalogue contributes to fostering data-driven discussions and understanding of the potential of decarbonization technologies.

The expected outcome of this process is a broader consensus on the potential.

RESULTS

The results will be integrated into the existing energy system model and can create first insights into cost-optimal applications of these technologies.

The results will contribute to making the Viet Nam Energy Outlook Report 2023 more comprehensive and enable decision-making on investments.
