Paving the way for zero carbon energy

The European Climate Foundation (ECF) has published its “Roadmap 2050: a practical guide to a prosperous, low-carbon Europe” which calls for more aggressive energy efficiency, the build-out of the power grid, regionally integrated market operations, energy market reform, smart grids and a firm commitment to phase out high-carbon assets on a fixed timetable.

According to the ECF, any delay in acting on these urgent priorities, and failure to better coordinate action across borders from the outset, “will foreclose options, increase risks and dramatically raise the costs of achieving Europe’s energy and climate objectives”.

The project finds that in a decarbonised power system, the future cost of electricity is comparable to the future cost of electricity in the current carbon-intensive infrastructure. Roadmap 2050 also shows that with the necessary investments in energy efficiency and Europe’s power network infrastructure, a decarbonised power sector using available technologies can provide the same high level of reliability that consumers enjoy today, in all low/zero carbon pathways.

The report was authored by the ECF with technical and economic analysis by Imperial College London, KEMA, Oxford Economics and McKinsey & Company and policy analysis by E3G and the Energy Research Centre of the Netherlands (ECN). AMO, a research and design studio within the Office for Metropolitan Architecture, contributed to the content development through the production of a graphic narrative which conceptualizes and visualizes the geographic, political, and cultural implications of the integrated, decarbonised European power sector.

Four decarbonised scenarios

Roadmap 2050 looks at the economic, service reliability, infrastructure, energy security and policy implications of the European power system in 2050 in four decarbonised scenarios. The pathways do not rely on imported electricity and are based on existing or late stage development technologies including renewables such as solar, wind, biomass, geothermal and also non-renewable low-carbon resources such as carbon capture and storage (CCS) and nuclear:

1. 40% renewables, with the remaining 60% supplied evenly between non-renewable low-carbon technologies: CCS and nuclear
2. 60% renewables, with the remaining 40% supplied evenly between non-renewable low-carbon technologies: CCS and nuclear
3. 80% renewables, with the remaining 20% supplied evenly between non-renewable low-carbon technologies: CCS and nuclear
4. The study has also assessed the technical and economic feasibility of a scenario with 100% renewable electricity, requiring no nuclear power and limiting CCS application to heavy industry, including solar power from North Africa and breakthroughs on enhanced geothermal power generation.

When the Roadmap 2050 project started, a number of widely shared assumptions dominated the debate on the future of the European power sector. These included assertions that high-renewable energy scenarios would be too unstable to provide sufficient reliability, that high-renewable scenarios would be uneconomic and much more costly, and that technology breakthroughs would be required to move Europe to a zero-carbon power sector. Roadmap 2050 has found all of these assertions to be incorrect.

With the exception of existing hydroelectric facilities, almost all of the power generation capacity required to supply Europe in 2050 will need to be built in the next 40 years. This is a major undertaking regardless of the energy mix, and would pose a massive challenge even in a high-carbon scenario.

The key finding of the Roadmap 2050 project is that the challenge is basically the same in either a high-carbon, low-carbon or zero-carbon energy scenario, in terms of overall cost and scale.

What does change significantly is the required level of investment early in the cycle. Capital expenditure on energy infrastructure will need to double in the next 15 years to deliver a zero-carbon power sector by 2050. But in that scenario, the overall energy bill for the economy will be heading downward by 2020, and the day-to-day running costs fall fast throughout the period.

As well as studying the technical requirements of the grid and power infrastructure and the economics of the various scenarios, the Roadmap 2050 project has also delivered an analysis of the policy requirements for decarbonisation of the power sector by 2050.

2015 a key year

Action before 2015 is a prerequisite for decarbonisation by 2050. Immediate policy development and implementation should focus on:
• Energy Efficiency measures, creating cost savings and reducing demand.
• Investments in regional networks and local smart grids and coordination of power market operations among member states, maximizing the value of low-carbon investments and minimizing back-up supply and load-balancing requirements.
• Market reform to ensure an effective investment scenario.

Roadmap 2050 shows that existing policy frameworks can be adapted to support decarbonisation of the European power-sector, but that an holistic approach is needed, with rapid action at both regional and national level required.

The Roadmap 2050 project shows that the benefits of the low-carbon transition by far outweigh the challenges and that a commitment now to a systemic low-carbon transformation of the energy sector is ultimately the winning economic strategy for competitiveness, jobs and low-carbon prosperity in Europe. Achieving at least 80% greenhouse gas reductions in 2050 based on zero carbon power generation in Europe is technically feasible and makes compelling economic sense.
