A CCS Roadmap for Portugal

Publish date: April 1, 2015

Bellona has been an active contributor in a year-long project which has resulted in the publication of a CCS Roadmap for Portugal. A key finding of the Roadmap is that CCS forms part of a least-cost strategy to achieving climate targets in Portugal in a deep decarbonisation scenario. To this end, a conducive policy framework and sufficient public funds would need to be guaranteed.

«These kinds of roadmaps are precisely the sort of thing we need to see across EU Member States as they allow us to set a path toward 2050. If we only look to achieve 2020 or 2030 targets there is a real danger of missing the bigger picture – where CCS is essential – and finding ourselfs trapped with emissions we cannot cost-effectivley reduce» said Director of Bellona Europa, Jonas Helseth.

The importance of developing CCS Roadmaps was also highlighted in the final summary report delivered to the European Commission on the review of the CCS Directive, to which Bellona contributed. One of the key recommendations listed in this report is for Member States to develop national decarbonisation plans which include CCS (or else explain how they are going to meet 2050 climate targets without it).

Bellona has also published CCS Roadmaps for Greece, Hungary, Romania and Poland, as well as a study of CCS in Ukraine. These can all be found here.

The Portuguese Roadmap looks at the role CCS technology can play in decarbonising the country’s energy and industry sectors. It also considers cost-effectiveness of CCS deployment, and the potential risks and benefits for economic development. Some key findings are:

  • With an 80% GHG reduction target, CCS technology is deplyed as cost-effective technology from 2030;
  • Under all mitigation scenarios modelled, CCS is deployed in significant volumes in the cement sector;
  • Given the availability of renewables generation in Portugal, deployment of CCS in the power sector is relatively low and varies significantly depending on the scenario examined;
  • In Portugal onshore CO2 storage offers the lowest costs solution, but the roadmap takes into account that offshore capacity is more available and politically more feasible;
  • The difference in the total energy system costs (including supply and demand side, such as industry) between the scenarios with and without CCS, indicate that for all the scenarios, in the long term, earnings surpass costs – and that alternative mitigation technologies will be more expensive.

The CCS Roadmap for Portugal is written by the partners of the project CCS-PT: Perspectives for capture and sequestration of CO2 in Portugal: Bellona, CENSE research group, CGE research group, National Laboratory of Energy and Geology and REN. It was undertaken with financial contributions from the Global CCS Institute (GCCSI).

The Roadmap can be downloaded from the project website.

The role of CCS in Germany’s climate toolbox: Bellona Deutschland’s statement in the Association Hearing

After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.

Bellona’s new working paper analyzes Russia’s big LNG ambitions the Arctic

In the midst of a global discussion on whether natural gas should be used as a transitional fuel and whether emissions from its extraction, production, transport and use are significantly less than those from other fossil fuels, Russia has developed ambitious plans to increase its own production of liquified natural gas (LNG) in the Arctic – a region with 75% of proven gas reserves in Russia – to raise its share in the international gas trade.
