50Hertz and TenneT awarded for PtG projects

26.07.2019

Last week, Peter Altmaier, the German Federal Minister for Economic Affairs and Energy, announced the winners of the ideas competition “Reallabore der Energiewende” (“Real Laboratories of the Energy Transition), which aims to promote promising energy technologies of the future, especially in the field of hydrogen technology. The winners include the two TSCNET shareholders 50Hertz, the transmission system operator (TSO) from north-east Germany, and Tennet, the Dutch-German TSO, as they are both involved in award winning projects.

Tennet is cooperating with Gasunie and Thyssengas for ELEMENT ONE, a power-to-gas (PtG) plant to be built in the German federal state of Lower Saxony, which will be capable of converting up to 100MW of electrical power into gas. ELEMENT ONE is in the planning phase, but the project partners are confident that the results of the project will provide crucial information on electricity and gas grid integration, the development of operator models and the regulatory environment. With their approach, they aim to accelerate the urgently needed transfer of technology and innovation from research to practice in the field of sector coupling and hydrogen technology.

Key technologies of energy supply
50Hertz is involved as associated partner in two winning PtG projects: “GreenHydroChem Mitteldeutsches Chemiedreieck“ in Saxony-Anhalt, and “Reflau – Referenzkraftwerk Lausitz“ in Brandenburg. These two projects also focus on sector coupling and hydrogen technology. The partners for GreenHydroChem are Siemens, Linde, and the Fraunhofer Institute for Microstructure of Materials and Systems (IMWS). With a 50MW electrolyser, regeneratively generated electricity is first to be converted into hydrogen and oxygen. The hydrogen is then converted in refineries into base chemicals and methanol, which can be blended with conventional fuels for the use in the transport sector. With Reflau, the partners want to combine and test in practice key technologies of energy supply with renewable energies and hydrogen as a chemical storage.

Dr. Dirk Biermann, Chief Markets & System Operations Officer at 50Hertz, welcomes the support for innovative technologies: “With our involvement in the laboratories, we are specifically promoting the development of Power-to-X technologies for the energy market. Because if things get serious in a few years’ time, we will need proven and grid-compatible experience with this new technology.”

Wind power hub promotes climate goals

10.07.2019

It’s only been a good three years since TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), first presented the concept of a North Sea Wind Power Hub (NSWPH) to the public. From then on, the vision has taken concrete shape and the hub consortium has been consistently expanded, now including further TSCNET shareholder Energinet from Denmark, the port of Rotterdam and the Dutch natural gas company Gasunie, as power-to-gas applications are an important component of the concept.

In future years, when large wind regions in the North Sea are defined for development, it will be possible to implement several hubs to support the energy transmission infrastructure. These NSWPHs will then combine generation, storage and transmission of wind energy with a multinational interconnection of North Sea riparian states and thus promote the large-scale implementation and integration of offshore wind energy. The NSWPH partners have now presented the results of the project assessment phase. In recent months, they not only analysed options for the construction of wind farms in the North Sea, but also conducted a large number of studies, examined various scenarios and held intensive discussions with policy makers, leading offshore developers and non-governmental organisations.

The studies and investigations have confirmed the technical and economic feasibility of the hub concept. Furthermore, they have shown that large offshore wind capacities must be developed in the North Sea in order to achieve the goals of the Paris Climate Convention in due time. The targeted capacities range from 70 to 150GW by 2040 and up to 180GW by 2045. Depending on the scope of development, the NSWPH could lay the foundation to supply hundreds of millions of Europeans with green electricity. To take the concept forward, the Danish, Dutch and German governments as well as the European Commission are invited by the NSWPH consortium to consider setting up a consultation.

Investing for the energy future

27.06.2019

TSCNET shareholder Amprion, one of the four German transmission system operators (TSOs), presents its Annual Report 2018 on a specially designed website. What, from a TSO’s perspective, is most necessary for the successful energy transition in Germany – the sustainable expansion of the transmission system so that green electricity can be provided nationwide – is clearly reflected in Amprion’s figures for 2018: Amprion further increased its investments in grid extension, which amounted to €763m in 2018 and were 8.5% higher than in the previous year.

However, it is not sufficient for TSOs alone to fulfil their role, especially as grid extension needs to be accelerated significantly to keep pace with the expansion of the renewables. Politics must also help by setting the right course to promote the cross-sector transformation of the energy system. Amprion therefore calls for a national master plan for electricity and gas. Dr. Klaus Kleinekorte, CTO at Amprion, explains: “It is not enough just to connect renewable energies to the grid. From our system responsibility, we have the task of integrating them into the energy system.” This requires innovative concepts and technologies such as power-to-gas.

Dr. Hans-Jürgen Brick, Chief Commercial Officer and CFO of Amprion, adds at the company’s annual press conference in the German capital of Berlin, that the expansion of the electricity system as outlined in the German Network Development Plan remains the indispensable basis for achieving the climate targets and the secure and cost-effective power supply of the German conurbations. “Amprion is thus investing more than €9.3bn in its grid over the next ten years.”

Energinet explores PtG potentials

22.05.2019

The generation of renewable energy is volatile and the storage of green electricity at times when production exceeds consumption is an ever-increasing challenge for energy market participants. Power to gas (PtG) technologies appear to be particularly effective in compensating for the weather-related volatility of the renewables. Since TSCNET shareholder Energinet is not only the Danish transmission system operator (TSO) for electricity, but also for gas, the company is ideally suited to profoundly evaluate the PtG potential. The Danish national energy goal is a 100% climate-neutral energy system by 2050, and PtG can play an important role in achieving it.

Energinet’s gas grid could be an essential tool for the transmission of solar and wind energy in Denmark’s energy system of the future, as the energy can be stored and transported in the gas pipelines with hydrogen as the energy carrier. To this end, the electricity is converted into hydrogen, which can then be mixed with natural gas. The TSO is currently testing how much hydrogen the gas grid can handle. The tests take place near the West Jutland town of Varde and are part of the “Hydrogen Injection in the Gas Grid” project, in which Energinet is cooperating with the Danish Gas Technology Centre and IRD Fuel Cells.

The gas in the pipelines near Varde is presently mixed with 12% hydrogen, the research target is 15%. At the beginning of the tests in summer 2017, it was only 2%, so the results are promising. „Using hydrogen as an energy carrier allows us to connect the electricity and gas sectors,“ explains Jesper Bruun, project manager at Energinet, and adds: „Once we are able to handle the hydrogen in the gas grid, we will have an extensive and efficient infrastructure in place for transport and storage.“

Map of German PtG plants

25.04.2019

With Power-to-Gas (PtG) technologies, sustainable electricity can be converted into gas and then stored in the existing gas infrastructure, transported and provided as needed – independent of the natural volatility of wind and solar energy. Forecasts up to 2050 indicate that comprehensive and effective climate protection is not possible without PtG. The “Deutscher Verein des Gas- und Wasserfaches” (German Association of the Gas and Water Sector – DVGW), an independent technical-scientific network for all questions related to gas and water supply, has published an updated map giving an overview of all PtG projects in Germany, including both completed and planned facilities.

The DGWV map shows that the number of PtG plants in Germany as well as their installed capacity is constantly increasing compared to previous statistics. 35 PtG plants are currently in operation with a total capacity of around 30MW. However, most of them are pilot or demonstration projects on a small scale and serve research purposes. Industrial-scale plants are still the exception, also for the 16 projects in planning.

Nevertheless, total PtG capacity will increase significantly in the future (estimated at 273MW), mainly due to two 100MW projects being implemented by two TSCNET shareholders: Amprion, one the four German transmission system operators (TSOs), and the Dutch-German TSO TenneT are pursuing the two most powerful sector coupling projects currently underway in Germany: “hybridge” and “ELEMENT ONE” which are planned at two different sites in the German federal state of Lower Saxony. According to current planning, “ELEMENT ONE” will be gradually operational by 2022 and “hybridge” will be fully operational by 2023.

PtG pilot plants on an industrial scale

29.03.2019

Power-to-Gas (PtG) technologies have the potential to compensate for the weather-related volatility of renewable energies. More specifically, PtG can be used to convert sustainable electricity into gas (green hydrogen or methane), so that the gas infrastructure is additionally available for the transport and storage of electricity from renewable sources. The TSCNET shareholder Amprion, one the four German transmission system operators (TSOs), and TenneT, the Dutch-German TSO, are taking the next important step towards implementing the two most powerful sector coupling projects currently underway in Germany: “hybridge” and “ELEMENT ONE”.

The respective gas transmission partners of Amprion and TenneT are Open Grid Europe for the “hybridge” project and Gasunie and Thyssengas for ELEMENT ONE. Both PTG plants are to convert up to 100MW of electrical power into gas. Their construction is planned at two different sites in the German federal state of Lower Saxony, each close to wind power generation centres and well-developed gas infrastructure.

The grid operators have submitted the necessary investment applications for both projects on 29 March to the Bundesnetzagentur (German Federal Network Agency). If the Agency gives the green light, ELEMENT ONE will be gradually operational by 2022 and hybridge will be fully functional by 2023. Dr. Klaus Kleinekorte, CTO at Amprion, comments on the application, that major PtG projects must now be pushed forward, “if we want to use PtG technology on a large scale in Germany in the 2030s”.

Royal interest in the Wind Power Hub

07.03.2019

TenneT, the Dutch-German transmission system operator (TSO), had the honour of hosting high-ranking visitors. During the German-Dutch trade delegation meeting on 6 March 2019 in the German North Sea port of Bremerhaven, Manon van Beek, CEO of the TSCNET shareholder, presented the vision and current plans for the North Sea Wind Power Hub in attendance of the Dutch King Willem-Alexander and Queen Máxima.

The North Sea Wind Power Hub concept combines wind energy production, storage, and transmission with a multinational interconnection of North Sea riparian states. In addition to TenneT, the international hub consortium includes the Danish TSO Energinet, another TSCNET shareholder, the port of Rotterdam and the Dutch natural gas company Gasunie. Hence, power-to-gas technologies are also involved in the hub concept. A transnational transmission grid, controlled through a distribution hub in the North Sea and enabling the feed-in and distribution of vast quantities of offshore wind energy, would strengthen the whole European energy market and increase the security of supply across the continent.

The Dutch royal couple took great interest in the virtual and interactive model of the hub concept showcased at the meeting. Manon van Beek was most appreciative of this aristocratic concern: “We are especially pleased and honoured by the interest of the royal couple in the energy hub.” The TenneT CEO considers the Power Hub to be a valuable instrument in achieving the objectives of the Paris Agreement. In this regard, the royal visit was beneficial because the realisation of a low-carbon energy future “requires international cooperation and coordination, political momentum and courage and the support of non-governmental organisations”, van Beek concluded.

TenneT and Gasunie present “Infrastructure Outlook 2050”

15.02.2019

Electricity grids in Europe are increasingly confronted with the fluctuating feed-in of renewable energies. Consequently, they need more flexibility, which can be provided by the comprehensive coupling of sectors such as energy, transport, industry and heat. Many European transmission system operators (TSOs) have identified the integration of electricity and gas transmission infrastructures as a promising approach to fulfilling the requirements of the coming sustainable energy system. Electricity and gases must complement each other, since interlinking both grid types creates new storage possibilities and also provides additional transport options for renewables. Both factors will help to keep energy supplies reliable and affordable also in the low carbon energy future.

TSCNET shareholder TenneT, the Dutch-German TSO for electricity, and Gasunie, the Dutch TSO for gas, each operate grids in the Netherlands as well as in Germany. Last year they entered into a sector coupling partnership with plans for the Power-to-Gas (PtG) pilot plant “ELEMENT ONE”. Now the TSOs have presented their joint “Infrastructure Outlook 2050”. It clearly illustrates that the existing electricity and gas infrastructures in the Netherlands and Germany continue to play a decisive role in coping with the increase in renewable energies and achieving the Paris climate targets. The main conclusion of the joint TSO study is that electricity and gas networks must be more closely interconnected by 2050 in order to meet the objectives. The Outlook is also the first document of its kind to consider various scenarios for the future development of energy supply.

The importance of hydrogen from PtG technologies for energy storage and transport is also highlighted. But even despite the potential of sector integration, further expansion of the electricity grid remains essential, as all scenarios envisage a significant increase in the necessity of electricity transport. In addition, however, there must also be backing from political decision-makers and the creation of a clear, supportive regulatory framework. Manon van Beek, CEO at TenneT, argues that “energy systems are not converted overnight but require sustained, joint efforts”. She therefore sees the need for close cooperation between all those involved in the energy market. In this respect, the “Infrastructure Outlook 2050” represents a “solid, joint start with fresh insights”.

Hybridge to couple energy sectors

11.02.2019

Last summer, TSCNET shareholder Amprion, one the four German transmission system operators (TSOs) for electricity, and Open Grid Europe (OGE), German TSO for natural gas, announced a collaboration in the field of sector coupling by means of power to gas (PtG) facilities. PtG technologies offer promising perspectives for a low-carbon energy future. Now the two partners are ready to launch the sector coupling at system level in Germany with the project “hybridge” comprising an electrolyser in the 100MW class and a hydrogen infrastructure.

At a joint press conference on 11 February in the German capital of Berlin, the current status of hybridge and further steps were presented. Since the partners, who estimate the costs for the entire project at €150m, are ready to enter the approval phase, Dr. Klaus Kleinekorte, CTO at Amprion, explained that the regulatory framework must now be set up quickly. The more so, as it is crucial for the German climate targets that PtG is available in the GW range from 2030. “The ball is in the court of politics. If the course is set now, the plant can already go into operation in 2023,” commented Dr. Kleinekorte.

The ideal location for the first PtG plant in the projected size, in which electricity from renewable energies is converted into green hydrogen and partly further into green methane via an electrolyser, was found at an intersection between the Amprion and OGE grids in the district of Emsland in the northwest of the German federal state of Lower Saxony. The regional natural gas storage facilities, which can be converted to hydrogen in the future, also contribute to optimal conditions for the development of a hydrogen grid to complement the 100MW electrolyser. Amprion and OGE intend to further develop an existing OGE pipeline for the exclusive transport of hydrogen. The concept of Amprion and OGE for sector coupling at system level also includes non-discriminatory third-party access for all market participants to the planned grid coupling infrastructure.

Coupling of renewables and PtG for climate targets

11.12.2018

In order to achieve ambitious climate targets, a rapid expansion of renewable energy generation is essential. The German market still has great offshore potential in this respect. However, regenerative expansion makes no sense if the corresponding transport or storage capacities are lacking. TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), is already known for its sustained efforts to significantly expand the transmission infrastructure in its control area as environmentally friendly as possible. But the TSO is also very active in the development of storage concepts, just consider, for example, the storage potential of the North Sea Wind Power Hub project or the “ELEMENT ONE” power-to-gas (PtG) pilot plant.

Together with Siemens and Shell, both global players in their respective fields, Tennet is now making additional efforts to promote the renewables as well as PtG. The three companies are convinced that green hydrogen will play a decisive role in the future energy mix as the basis for many power-to-X applications, which are technologies for storage and other uses of surplus electricity. TenneT, Siemens and Shell have thus commissioned a study on a new type of tender model for offshore wind capacity. This model intends to link the awarding of contracts for the operation of offshore plants to the production of hydrogen: The additional wind power from such facilities should not put too much strain on the onshore grid, but rather be used to generate hydrogen and even stablise the electricity grid. The green hydrogen can be transported via the gas grid and then be used in other sectors, such as industry or mobility.

Lex Hartman, Managing Director of TenneT, is determined to not squander any potential for renewable energies and convinced that PtG technologies provide flexibility, reduce the strain on the grid and make power supply more secure. “In the long term,” Mr Hartman continues, “the combination with hydrogen production can also be applied throughout Germany to other renewable energies. This advances the energy transition and helps to achieve our climate targets.”
