The EPOS project : operationalizing cross-sectorial industrial symbiosis for the European industry

The EPOS project brings together five process industries from five key sectors: steel, cement, chemicals, minerals and engineering. With the intention of reinforcing competitiveness of the EU industry, EPOS partners aim to increase cross-sectorial knowledge and investigate cluster opportunities using an innovative Industrial Symbiosis (IS) tool. EPOS' main objective is to provide a wide range of technological and organisational options for making business and operations more efficient, more cost-effective, more competitive and more sustainable across the different process sectors. An innovative tool is to be developed, applying a proven methodology for the thermo-economical optimization of energy and resource use within and between industrial clusters, taking into account sustainability opportunities. To achieve the objectives of the EPOS tool, a cross-sectorial energy, material and service integration approach is considered, based on process integration methodology. This holistic tool will enable an on-site optimized resource management, further targeting cross-sectorial opportunities. The expected users are process industries, suitable for both small and large scale. The tool will be usable by non-experts, after a reasonable training period, and will thus have a user-friendly interface such that the final user will not be directly in contact with the internal model, but will rather use a 'high-level' platform that reflects his knowledge and understanding of the sites. In addition to the ongoing tool development, a full work package led by Strane is dedicated to developing a generic business case for industrial symbiosis, taking into consideration monetized and non-monetized aspects. One main focus includes internalizing positive social and environmental externalities within the business models of industrial companies. A market study of the potential for industrial symbiosis in Europe was performed. It included the mapping of all industrial sites in the EPOS sectors, the generation of more than 1000 possible synergies, and a preliminary assessment of the economic and environmental relevance of a selection of 28 synergies. The study highlighted industrial hotspots, a consistent approach to identifying and assessing synergies. Each EPOS sector demonstrated a good potential for industrial symbiosis. Future work of the EPOS Project will focus on deepening the analysis of business models and their associated environmental impact assessment, using the life cycle assessment (LCA) approach. The presentation will detail the methodology to link LCA and business models, which may serve as a reference model for future similar undertakings.

It includes the mechanism of electricity pricing on the Day Ahead Market (DAM) and the Imbalance Market (IM). The extra production volumes of Electricity from Renewable Energy Sources (RES-E) and the flexibility of electrical consumption of industries is provided as reserves on the IM. Five thousand simulations were run by using the agent-based model to gather data that were then fit in linear regression models. This helped to quantify the effect of feed-in tariffs and installed capacity of wind power on the consumption from renewable energy and market prices.

It includes the mechanism of electricity pricing on the Day Ahead Market (DAM) and the Imbalance Market (IM). The extra production volumes of Electricity from Renewable Energy Sources (RES-E) and the flexibility of electrical consumption of industries is provided as reserves on the IM. Five thousand simulations were run by using the agent-based model to gather data that were then fit in linear regression models. This helped to quantify the effect of feed-in tariffs and installed capacity of wind power on the consumption from renewable energy and market prices. The consumption from renewable sources, expressed as percentage of total system consumption, increased by 8.17% for every 10% increase in installed capacity of wind power. The sharpest increase in renewable energy consumption is observed when a feed-in tariff of 0.04 €/kWh is provided to the wind farm owners, resulting in an average increase of 9.1% and 5.1% in the consumption from renewable sources while the maximum installed capacity of wind power is 35% and 100%, respectively. The regression model for the annualized DAM prices showed an increase by 0.01 €cents/kWh in the DAM prices for every 10% increase in the installed wind power capacity. With every increase of 0.01 €/kWh in the value of feed-in tariffs, the mean DAM price is lowered as compared to the previous value of the feed-in tariff. DAM prices only decrease with increasing installed wind capacity when a feed-in tariff of 0.04 €/kWh is provided. This is observed because all wind power being traded on DAM at a very cheap price. Hence, no volume of electricity is being stored for availability on IM. The regression models for predicting IM prices show that, with every 10% increase in installed capacity of wind power, the annualized IM price decreases by 0.031 and 0.34 €cents/kWh, when installed capacity of wind power is between 0 and 25%, and between 25 and 100%, respectively. The models also showed that, until the maximum installed capacity of wind power is less than 25%, the IM prices increase when the value of feed-in tariff is 0.01 and 0.04 €/kWh, but decrease for a feed-in tariff of 0.02 and 0.03 €/kWh. When installed capacity of wind power is between 25 and 100%, increasing feed-in tariffs to the value of 0.03 €/kWh result in lowering the mean IM price. However, at 0.04 €/kWh, the mean IM price is higher, showing the effect of no storage reserves being available on IM and more expensive reserves being engaged on the IM. The study concludes that the effect of increasing installed capacity of wind power is more significant on increasing consumption of renewable energy and decreasing the DAM and IM prices than the effect of feed-in tariffs. However, the effect of increasing values of both factors on the profit of RES-E producers with storage facilities is not positive, pointing to the need for customized rules and incentives to encourage their market participation and investment in storage facilities.

The solution space includes heavy utilisation of renewables for the electrification of industrial processes and the use of renewable molecules. It is expected that more than 200 GW of offshore wind power will be installed in the North Sea region by 2050, which necessitates the need for bulk power transport together with storage facilities. Hydrogen production and storage systems can help balance the electricity grid and facilitate the maximum utilisation of offshore wind energy. Such systems also will affect the expansion requirements of electricity grids by reducing wind power curtailments and employing the existing natural gas network and hydrogen pipelines. This research investigates the optimal operation of a coupled wind-hydrogen system, which supplies green hydrogen to the industrial sites and injects it into the natural gas grid. The produced hydrogen can be utilised as a long-term storage medium for electricity generation as well. Moreover, in order to maximise the total annual profits and renewable energy utilisation ratio, the optimal design of the hydrogen system is studied by using historical data from the Belgian energy markets. The preliminary results show that net power curtailment can be reduced up to 63% by making use of the excess energy to produce hydrogen.
