The heated debates over the potential inclusion of nuclear power and natural gas in the EU taxonomy has again exposed the different interests of EU nations. Simon Göss at cr.hub, writing for Energy Brainpool, explains what parameters the EU taxonomy controls, what conditions are attached should the two technologies be classified as sustainable, as well as summarising those national interests and constraints. Critics say neither should be included, so that all efforts are put into new clean technologies and solutions. But high dependence on these two techs makes a nation a big fan. Nine nations use nuclear for over 30% of their electricity generation mix. Ten nations use gas for over 30%. Though inclusion in the taxonomy should make the financing of a technology easier, each asset must comply with a range of strict sustainability rules (emissions reductions, environmental, etc.) to actually qualify (note: even those rules have been called insufficient by critics). If the final version is passed by the European Parliament over the coming months, Göss says unhappy nations will find it very difficult to veto the new taxonomy (essentially requiring a two-thirds majority), so getting it right now will be essential for everyone. No wonder the arguments are intense.
The EU Taxonomy briefly explained
As the core of the EU sustainable finance action plan, the EU taxonomy aims to do one thing above all: channel financial flows into more sustainable activities. Specifically, sustainable finance means linking financial issues and the specific needs of the European economy for the benefit of the planet and our society (source: EU Commission). As a uniform classification system, the EU taxonomy aims to define under which conditions economic activities can be declared sustainable.
Especially for large investors, banks and insurance companies, and increasingly for other companies as well, public reporting requirements apply to their activities regarding sustainability. The idea behind this: The EU taxonomy creates incentives for a sustainable transformation of the economy.
Six environmental objectives
For several years, stakeholders from various working groups and institutions at the EU level have been developing the EU taxonomy. These include, for example, the EU Joint Research Center, the Technical Expert Group and the Sustainable Finance Platform. In general, activities must be aligned with the EU’s six environmental goals to be included in the taxonomy. These goals are:
- climate change mitigation
- adaptation to climate change
- sustainable use and protection of water and marine resources
- transition to a circular economy
- pollution prevention and control
- protection and restoration of biodiversity and ecosystems
Thus, the inclusion of a technology in the EU taxonomy is a way for funders and companies to be able to declare financing or economic activity in the relevant area as sustainable. This may be associated with better private financing conditions.
Firstly, however, the taxonomy has a signal and orientation effect. In no way does the taxonomy imply general governmental or EU-wide financing or subsidies of the technologies included.
Inclusion of Nuclear and Natural Gas in the proposal
On December 31, 2021, the EU Commission sent a draft regulation to the governments of the member states. In this draft, the Commission also included nuclear power and natural gas, which have long been controversial technologies. A version of the proposals can be found here.
France, for example, has specifically advocated the inclusion of nuclear power, partly so that the French energy company EDF can invest in its power plants. Meanwhile, at the German level (depending on party affiliation), the inclusion of gas-fired power plants is preferred.
However, the “Ampelkoalition” (coalition formed by the German parties SPD, FDP and Green Party) disagrees on this. Likewise, Federal Minister of Economy and Environment Habeck rejects the current proposal. Many see the inclusion of the two forms of energy as a compromise between France and Germany.
The power generation structure at the EU level
In order to understand the discussion around the taxonomy in terms of the energy industry, we will now have a look at the power generation structure at the EU level. Figure 1 shows the European electricity mix for 2021 (source: Energy-Charts).
Nuclear power and natural gas have been the two technologies with the highest electricity generation at EU level for the past five years. In 2021, for example, nearly 27 percent of the EU’s electricity came from nuclear power plants and 17 percent from natural gas.
Above all, these existing dependencies of electricity generation on nuclear power and natural gas in the EU countries lead to its classification as a sustainable technology. In addition, the political balance of power contributes to this.
It is therefore not surprising that at the EU level, the technologies currently still generating the most electricity are favoured in the respective countries. The inclusion of nuclear power and natural gas in the EU taxonomy would be subject to conditions.
Nuclear: usage, taxonomy rules
At the European level, it is important to note that many countries were already relying on nuclear power to mitigate greenhouse gases before the taxonomy. For example, expansion is planned or envisaged not only in France, but also in Romania, Bulgaria, the Netherlands, Poland and Estonia.
Figure 2 shows the share of electricity generation from nuclear power in the 13 EU countries with nuclear power plants in 2020. Clearly visible is the high share of over 30 percent in many EU member states (source: EU Commission).
According to the EU Commission’s draft, nuclear power plants should only be sustainable if they:
- meet the latest technical standards
- have received a construction permit by 2045
- possess a fund for the final disposal of radioactive materials
- dispose of a dismantling fund
The funds must have sufficient financial resources. The above conditions for classification should also apply to nuclear power plants whose operating lives are extended. Furthermore, the political level must approve continued operation until 2040.
Only nuclear power plants whose operating lives are extended after 2025 must also have a detailed plan for final disposal (source: Montel).
Gas-fired power plants: usage, taxonomy rules
Around 17 percent of European electricity is generated from natural gas. Here, too, the differences between countries are large. Gas-fired power plants account for a particularly high share of electricity generation in Belgium, Greece, Ireland, Italy, Latvia, Lithuania, Portugal and the Netherlands – i.e. primarily in countries that do not have a high level of generation from nuclear power.
Figure 3 makes this clear. It shows the share of electricity from gas-fired power plants in the 13 countries with the highest shares in 2020 (source: CREA). Generation from gas-fired power plants could also increase in Germany after the phase-out of nuclear power and with an accelerated coal phase-out.
In general, gas-fired power plants must have greenhouse gas emissions of less than 100 g CO2/kWh. This limit would probably only be achievable with CO2 capture and storage.
Exemptions for Gas-fired power plants with planning permission until 2030
For gas-fired power plants that receive a building permit by December 31, 2030, less restrictive regulations apply in order to be classified as sustainable. Here, there are still two options for gas-fired power plants:
Under the first path, direct greenhouse gas emissions must be below 270 g CO2/kWh for power generation. Highly efficient cogeneration plants can fulfil this condition. For normal gas and steam power plants, the value is generally between 300 and 350 g CO2/kWh.
The second option is that power plants must not emit more than an average of 550 kg CO2/kW per year over 20 years. This would mean that power plants would have to reduce the number of hours they operate per year. In addition, they would only be allowed to produce electricity during high-load phases or when generation from renewables is low. Regardless of the two options above, new gas-fired power plants that receive a permit by the end of December 2030 must demonstrate that the
- electricity generated cannot yet be efficiently produced by renewables
- gas-fired power plant replaces an existing plant with higher emissions and the emissions reduction per kWh is at least 55 per cent
- plant is capable of co-firing low-CO2 and renewable fuels and the share of these fuels is at least 30 percent from 2026, at least 55 percent from 2030, and as much as 100 percent from 2036
- a coal phase-out is planned in the country concerned and laid down in an official plan
What are the next steps?
Environmental associations and individual countries have already strongly criticised the new regulations. Austria even wants to file a lawsuit against the inclusion of the two energy sources in the EU taxonomy. Energy industry players doubt that enough low-CO2 or renewable fuels will be available for the gas-fired power plants (source: Montel). However, major investors and donors, through the IIGCC (Institutional Investors Group on Climate Change), have also attacked the inclusion of gas in the taxonomy in an open letter to the EU (source: Euractiv).
On a political level, the EU Commission wanted to consult the draft with the member states first by 12th of January 2022. MEPs extended this deadline until 21st of January 2022. After that, the Commission will present the final proposal. The Council of Member States or the EU Parliament can still veto the proposal within four months before it becomes binding for all EU countries.
Conditions for a veto
For a veto, however, at least 20 EU states representing at least 65 percent of the total EU population or at least 353 MEPs in the EU Parliament must vote against the draft. At the country level, there will not be enough opposition due to the existing and continued dependence on the two energy sources (see figures 2 and 3).
On the other hand, there is greater opposition in the Parliament to the inclusion of nuclear power and natural gas. Nevertheless, given the balance of power, a veto is the most unlikely outcome. So whether the EU taxonomy will also classify nuclear power and natural gas as sustainable activities in the future has not yet been decided. However, even then, the use of the two technologies would come with some conditions.
It also remains to be seen whether the taxonomy classification will stimulate private-sector investment. Due to the high construction costs and time delays of nuclear power plants and the currently high gas prices, renewable energies could be cheaper and more profitable compared to the two alternatives.
