Enefit Volt builds 40 electric vehicle charging stations with support of EU funds

With the help of EU funds, Enefit Volt is expanding its charging services to other local markets. The company will install 40 chargers with at least 150 kW capacity at 20 locations across 4 countries by the end of 2024, thanks to the CEF (Connecting Europe Facility) support. The chargers will allow drivers to charge their vehicles for up to 100 km in just minutes, depending on the vehicle model.

The chargers will be located along the TEN-T (Trans-European Transport Network) route that connects Tallinn and Krakow in the south of Poland, passing through cities like Riga, Vilnius and Warsaw.

This project is funded by the European Union's CEF Transport Alternative Fuels Infrastructure Facility with a grant of 2,000,000 euros under the agreement No. 101101639.

Eesti Energia will participate in a major Europe-wide electric car project

Eesti Energia will be participating in a major Europe-wide electric car project aiming to develop user-centric and innovative next-generation charging solutions. The project will begin in 2020 under the leadership of Renault and will end at the end of 2023. The budget of the development project is EUR 19 million, of which the European Union will cover EUR 15 million. The project will have 33 partners across Europe (France, Netherlands, Italy, Estonia, Germany, etc.). Funded by Horizon 2020, the project aims to test and identify the best possible charging solutions for electric cars.

During the project, Eesti Energia will install ultra-rapid chargers for electric cars in the vicinity of Tallinn, with the capacity to stabilize the power network. Eesti Energia will be developing charging solutions for private and commercial users of electric cars to provide simple, convenient and useful charging services that will also support the highest possible quality of electrical connection anywhere in the network.

The project has received funding from the European Union 's Research and Innovation Program, Horizon 2020, under Grant Agreement 875683.

Applied study to decrease the sulphur compounds in shale oil products

Enefit is starting cooperation wih TalTech to find solutions for reducing sulphur content in the oil products by studying the pyrolysis process parameters and the effect of possible additives to the sulphur content in different fractions. After an application plan will be made for the chosen technological application in the Enefit280.

Main goals:
  • Report on results of the identification and classification of sulphur compounds in the shale oil. Also, possible reaction paths for removing sulphur from the shale oil fractions.
  • Subject to the analysis results a proposal will be made for modification of the pyrolysis parameters and inclusion of additives for further analysis.
  • Preparation of the application plan for the most suitable technological adaptation in Enefit's oil plants.
  • As a result, an input will be received for further development of shale oil products. It will contribute to Enefit's products competitiveness and continued production.
  • The project has received EUR 211 500 of support from the European Union Regional Development Fund.

    Applied study for decreasing the CO2 footprint of the oil-winning process

    The aim of the study is to find a best CCU/CCS technology for Enefit280 in cooperation with the technology providers and develop an application plan for the chosen technology with the break-even price of 50 EUR/t.

    TA partner sees Oxyfuel technology as a very potential candidate and aims to conduct a thorough investigation into this technology. This is subject to the condition that all the other potential technologies are considered equally. Based on the finding of technology analysis the focus will be adjusted.

    Main goals:
  • Oil-winning industry CO2 analysis.
  • Enefit280 suitability assessment of the globally applied and studied CCS/CCU technologies.
  • Development of further testing and research plan to validate the suitability of most promising technologies.
  • Application plan to introduce an industrial scale operation.
  • The project has received EUR 200 000 of support from the European Union Regional Development Fund.

    Study of ways to improve the efficiency of mine survey operations through remote monitoring methods

    Eesti Energia has modernised its mining technologies and made a number of innovations to make operations more efficient and environmentally friendly. However, this has significantly increased the volume and complexity of mine survey operations.

    Together with Tallinn University of Technology, we are conducting an applied research project to develop a metering and analysis method using semi- and fully automated remote monitoring solutions, which will make mine survey operations safer. In addition, modern metering technologies would increase productivity and reduce losses.

    The main objectives of the project are:
  • to develop the most suitable, reliable and efficient set of tools and equipment for mine survey operations for the renewed technologies of Estonian oil shale mines;
  • to develop the most reliable and efficient metering methodology for measuring the volume of mineral resources extracted;
  • to propose the necessary software developments for the processing of data and calculation of volumes of the new metering methodology.
  • The project has received EUR 42,764 of support from the European Union Regional Development Fund.

    Study of the enrichment possibilities of the mining mass originating from lava complex

    In the context of ever-stricter environmental standards and ever-increasing environmental charges, Eesti Energia is looking for solutions to reduce its environmental impact and improve its oil shale valorisation processes.

    The study, conducted in cooperation with the Mining Department of the Institute of Geology at TUT, will help Eesti Energia to select enrichment technologies and evaluate their profitability in a smarter way. The project contributes to a more efficient use of oil shale and helps to reduce specific emissions and waste (waste rock, ash, COx, NOx, SOx).

    The main objectives of the project are:
  • To create a calculation model to predict the quality and yield of the enrichment process;
  • To develop an oil shale enrichment scheme suitable for the enrichment of the ore from longwall mining in the selected mining field according to the quality requirements of the consumer (fuel efficiency, particle size, humidity);
  • To choose the optimal enrichment scheme (equipment selection) according to output quality requirements and ore characteristics.
  • The project has received EUR 62,100 of support from the European Union Regional Development Fund.

    Study of the relationship between the sulphur content of oil shale and the properties of shale oil

    Eesti Energia produces approximately 400,000 tons of shale oil per year, which is consumed by heat producers, energy companies, manufacturers and sellers of marine fuels, road builders, agricultural producers and other companies. Essentially, shale oil is synthetic petroleum that needs to be heated without air to obtain it. This process is known as pyrolysis.

    Our shale oil is characterised by low sulphur content. Further reduction of the sulphur content will allow the competitiveness of shale oil to be even more enhanced. As sulphur gets into oil from oil shale, we have started to study, in cooperation with the University of Tartu, the relationship between the amount and forms of sulphur in oil shale and the quality of oil produced from oil shale. By studying the behaviour of oil shale sulphur in the pyrolysis process, we hope to find solutions that will enable more targeted planning of oil shale mining and use in the future.

    The main objectives of the project are:
  • to clarify whether shale oil with variable sulphur contents affects the characteristics of shale oil;
  • to assess whether selective mining can reduce unwanted impurities in shale oil without refining it;
  • to offer opportunities for more targeted planning of oil shale mining and use.
  • The project has received EUR 56,954 of support from the European Union Regional Development Fund.
