Abstract:
Comprehensive information on energy-related topics, such as take-up of heat pumps, industrial natural gas consumption and prices, and battery connections to the electricity grid, is either not available in Europe in a timely manner, or not available at the level of granularity, reliability and consistency needed for informed decision-making. Certain information is simply not collected, while other information is collected but is not comparable or consistent across Europe, or is hard to access. European policy targets, such as greenhouse-gas emission reduction pathways, are evaluated using models for which input assumptions and parameters are not public knowledge. It should be a European Union priority to improve this situation. Doing so will enable better decision-making by policymakers and companies. This is especially relevant when Europe faces the triple challenge of decarbonisation, ensuring security of energy supply and growing its internationally competitive energy-consuming industries. The EU status quo is that good energy information is provided by a mix of institutions, agencies, national bodies, industrial associations and non-governmental organisations, but with substantial room for improvement. Lessons can be learned from the United States Energy Information Administration and the European Environment Agency, which was established to better coordinate climate data. Improving energy information will involve difficult political decisions. A process should be started to evaluate the options and to measure the continued cost of inaction.

Abstract:
Three quarters of the European Union’s greenhouse gas emissions stem from burning coal, oil and natural gas to produce energy services, including heating for buildings, transportation and operation of machinery. The transition to climate neutrality means these services must be provided without associated emissions. It is not possible today to determine tomorrow’s optimal clean energy system, largely because the cost, limitations and capability developments of competing technologies cannot be predicted. Energy systems with widely diverging shares of ‘green fuels’, in the form of electricity, hydrogen and synthetic hydrocarbons, remain conceivable. We find the overall cost of these systems to be of the same order of magnitude, but they involve larger investments at different stages of value chains. A large share of synthetic hydrocarbons would require more investment outside the EU, but less in domestic infrastructure and demand-side appliances, while electrification requires large investment in domestic infrastructure and appliances. Current projections show an overall cost advantage for direct electrification, but projections will evolve and critical players may push hard for alternative fuels. Policy will thus play a major role in shaping this balance. Political decisions should, first, push out carbon-emitting technology, primarily through carbon pricing. The more credible and predictable this strategy is over the coming decades, the smoother will be both divestment from brown technologies and investment in green technologies. Second, policy needs to help ensure that enough climate-neutral alternatives are available in time. Clear public support should be given to three system decisions about which we are sufficiently confident: the massive roll-out of renewable electricity generation; the electrification of significant shares of final energy consumption; and rapid phase-out of coal from electricity generation. For energy services where no dominant system has yet emerged, policy should forcefully explore different solutions by supporting technological and regulatory experimentation. Given the size and urgency of the transition, the current knowledge infrastructure in Europe is insufficient. Data on the current and projected state of the energy system remains inconsistent, either published in different places or not at all. This impedes the societal discussion. The transition to climate neutrality in Europe and elsewhere will be unnecessarily expensive without a knowledge infrastructure that allows society to learn which technologies, systems, and polices work best under which circumstances.

3. Commercialisation contracts: European support for low-carbon technology deployment

Abstract:
Many of the technologies that can help the European Union become a net-zero emissions economy by 2050 have been shown to work but are not yet commercially competitive with incumbent fossil-fuel technologies. There is not enough private investment to drive the deployment of new low-carbon alternatives. This is primarily because carbon prices are neither high enough nor stable. There are a number of benefits from the deployment of low-carbon technologies that private firms do not factor in. These include the benefits of decreasing industry-wide costs over time, and the global climate benefits from the development of low-carbon technologies within the EU that can subsequently be exported. The result is an investment level below the socially optimal value in the EU. Commercialisation contracts could be implemented as a temporary measure to remove the risk associated with uncertain carbon prices for ambitious low-carbon projects. The aim of the contracts would be to increase private investment to the socially optimal level. Contracts would be allocated through auctions in which fixed prices for abated emissions over a fixed duration would be agreed on a project-by-project basis. On an annual basis, public subsidies amounting to the difference between the agreed carbon price and the actual EU carbon price would be provided to investors, depending on the total carbon emissions abated. As long as EU carbon prices are low, investors would receive larger subsidies to ensure their competitiveness. Contracts would be auctioned at EU level. This would generate increased competition compared to national auctions, leading to more efficient outcomes and preventing fragmentation of the single market. From about €3 billion to €6 billion would be provided to the main industrial emitting sectors annually, with the amount reducing as the EU carbon price rises and low-carbon technologies become competitive without subsidy.

4. Navigating through hydrogen

Abstract:
Hydrogen is seen as a means to decarbonise sectors with greenhouse gas emissions that are hard to reduce, as a medium for energy storage, and as a fallback in case halted fossil-fuel imports lead to energy shortages. Hydrogen is likely to play at least some role in the European Union’s achievement by 2050 of a net-zero greenhouse gas emissions target. However, production of hydrogen in the EU is currently emissions intensive. Hydrogen supply could be decarbonised if produced via electrolysis based on electricity from renewable sources, or produced from natural gas with carbon, capture, and storage. The theoretical production potential of low-carbon hydrogen is virtually unlimited and production volumes will thus depend only on demand and supply cost. Estimates of final hydrogen demand in 2050 range from levels similar to today’s in a low-demand scenario, to ten times today’s level in a high-demand scenario. Hydrogen is used as either a chemical feedstock or an energy source. A base level of 2050 demand can be derived from looking at sectors that already consume hydrogen and others that are likely to adopt hydrogen. The use of hydrogen in many sectors has been demonstrated. Whether use will increase depends on the complex interplay between competing energy supplies, public policy, technological and systems innovation, and consumer preferences. Policymakers must address the need to displace carbon-intensive hydrogen with low-carbon hydrogen, and incentivise the uptake of hydrogen as a means to decarbonise sectors with hard-to-reduce emissions. Certain key principles can be followed without regret: driving down supply costs of low-carbon hydrogen production; accelerating initial deployment with public support to test the economic viability and enable learning; and continued strengthening of climate policies such as the EU emissions trading system to stimulate the growth of hydrogen-based solutions in the areas for which hydrogen is most suitable.

5. Greening the recovery by greening the fiscal consolidation

Abstract:
In the wake of COVID-19, some economic recovery policies will help green the economy – for example, energy renovation of buildings. But there are limits to the share of stimulus that can be explicitly green. The European Union should therefore also green the fiscal consolidation by setting out the path to much higher carbon prices than today. This would guide investment and provide revenues to help the fiscal consolidation.

6. A European carbon border tax: much pain, little gain

Author:

Abstract:
The European Commission should not make the implementation of a carbon border adjustment mechanism into a must-have element of its climate policy. There is little in the way of strong empirical evidence that would justify a carbon-adjustment measure. Moreover, significant logistical, legal and political challenges will arise during the design. The EU should instead focus upon the implementation of measures to trigger the development of a competitive low-carbon industry in Europe.
