CCS in South Africa

Posted by on Monday, 28 February, 2011

More than ninety percent of South Africa’s power is generated from coal and other industries resulting in the release of over 400 million tonnes of carbon dioxide annually. As a part of South African government’s effort to reduce carbon dioxide emissions it has established the South African Centre for Carbon Capture and storage (SACCCS) to investigate the feasibility of CCS in South Africa. SACCCS was established in March 2009 as a division within South African National Energy Research Institute (SANERI) and is governed by a charter that has an initial five year plan.

The strategy of SACCCS is to develop and implement a roadmap for the commercial application of CCS in South Africa. The mission of SACCCS is to be the leading authority for all carbon capture storage related activities in South Africa. Its main objective is to prepare and promote the construction of a safe and reliable carbon capture and demonstration plant in South Africa.

The roadmap consists of five phases:

  • Preliminary Potential Investigation: A preliminary investigation was undertaken by the CSIR for the Department of Minerals and Energy showed theoretically that South Africa had capturable emissions and potential storage sites. Based on this premise, further investigations were initiated.
  • Geological Storage Atlas: A project to derive more authoritative storage information commenced during September, 2008. The Atlas identifies four possible CO2 geological storage basins in South Africa. Two are being explored – onshore areas of the Zululand Basin, with UK support, and the Outeniqua Basin, with European aid support. The Atlas will be taken into the Centre’s programme of work and further developed to locate a storage site suitable for the Test Injection.
  • CO2 Injection Experiment: The ultimate purpose of the Experiment is to show to decision makers that carbon capture and storage can be safely undertaken in South Africa. This experiment will end by 2016.
  • Demonstration Plant: A demonstration plant will test an integrated operating system under local conditions and forms an essential link between feasibility trials and a full scale commercial plant. This phase will demonstrate the capture, transport and safe injection of CO2 into South African geological formations. The magnitude of the demonstration plant is in the order of hundreds of thousands of tonnes of carbon dioxide per year.
  • Commercial Operation: A full scale commercial plant is envisaged once the result of the demonstration plant turns out to be positive. It is expected that this phase will not be a part of the South African Centre for Carbon Capture and Storage. The magnitude of the commercial scale operation is in the order of millions of tonnes of carbon dioxide per year.

Work plan of SACCCS:

The current focus areas of carbon capture and storage work in South Africa are therefore storage and regulation. After the publication of the Atlas the next logical step is the undertaking of the test injection experiment. The purpose of the test injection is a “proof of concept” to demonstrate that carbon storage can be undertaken in South Africa. The process of bringing South Africa to the test injection will also enable ancillary outputs that will be necessary for a carbon capture and storage industry in South Africa. The test injection phase will involve injecting some tens of thousands of tonnes of CO2 to measure the effect of injection of CO2. The results will determine the future of CCS in South Africa.

Carbon Capture and Storage, Geological Sequestration


European carbon capture storage a speech by Charles Hendry

Posted by on Wednesday, 23 February, 2011

Introduction

It’s an honour to be asked here today, and speak to you on how I see CCS moving forward. A subject very close to my heart, because its potential never ceases to amaze.

I think the advantages are clear. Fossil-fired electricity has a hatrick of ‘pros’. Reliability, availability and affordability!  It’s why fossil fuels will remain an important part in our future energy mix.

It’s not about low carbon versus affordability versus energy security. These must all work together.

This security is a major component to the economic regeneration that we are committed to starting.

Where CCS comes in

By 2020 well over half of the UK’s electricity generation will still be fuelled by coal and gas.

Look at the last few winters we’ve had? Look at how exceptionally cold and enduring they were.

We need to meet the challenge of de-carbonising the next generation of our fossil fuel-fired power stations.

That is why CCS is such a crucial element of this Government’s energy and climate change agenda. It is the only technology that can significantly reduce CO2 emissions from fossil fuel power stations – by as much as 90 per cent.

And it will play an important role in balancing the electricity system. Without CCS, halving emissions by 2050 will be 70 per cent more expensive.

CCS and green growth

We have already put in place one of the most comprehensive policy and regulatory frameworks in the world to encourage investment in CCS….

Europe also has a natural advantage in the form of the storage capacity available under the North Sea. The potential is enormous.

The estimated CO₂ storage capacity of the UK and its continental shelf alone is 22 GTonnes. That’s roughly 100 years of capacity for emissions from the power sector.

Demonstration of CCS

In the UK we have amongst the most advanced plans for a fossil fuelled power station with CCS anywhere in the world. We know better than anyone how difficult demonstration of CCS will be.

The market conditions are not adequate to fund the development and deployment of CCS at the pace we need.

That is why, as part of the Spending Review last October; we announced that up to a billion pounds will be invested in one of the world’s first commercial-scale CCS demonstrations on coal-fired electricity generating plant.

Projects 2-4

We know that 1 demonstration project is not sufficient in moving CCS to being a technically and commercially viable technology within the time frames required to meet our carbon reduction targets. That is why we have a commitment to continue public sector investment in a further 3 demonstration projects.

International policy

The work we do in delivering our first demonstration plants will provide large-scale exemplars. I want to see the experience and knowledge from these projects shared widely. We must learn from each other and share that knowledge with the rest of the world.

And we are supporting CCS capacity building in developing countries through the Carbon Sequestration Leadership Fund.

Domestic policy

This Government has, and will, put in place policies and regulatory frameworks to facilitate CCS but we must work with industry to address the delivery issues – the technical, financial and commercial challenges – if demonstration projects are to be built on time and CCS is to become commercially viable. That is why we set up the UK’s CCS Development Forum – to bring together leaders from industry, NGOs and the public sector to hold the Government to account on its CCS commitments.

We are also developing a CCS Roadmap to 2050 which will articulate our proposed timescales and set out the key technical, policy and commercial issues which need to be addressed, by when, and by whom, if CCS is to be commercially deployed from the 2020s and contribute to achievement of our 2050 target.

Investment

More than £110 billion of investment is needed in the UK in new power stations and grid upgrades over the next decade.

The hardest and most important challenge for the Department is on electricity market reform (EMR).

We want to drive investment in the UK and ensure this doesn’t go overseas, so we will ensure that the right level of an EPS is set and this is seen as a beacon of our long term investment framework

Conclusion

In short we need more energy but fewer emissions. And so to end where I began: the challenge is vast, the prospects daunting but it’s all within our reach. The glass is most definitely half full.

Much of the investment will have to be significantly bigger than in the past. And we need to take the public with us. Safety is a priority, but we also need to ensure we are explaining the benefits of CCS.

I’m grateful for the opportunity to share my thoughts with you all, and I look forward to hearing yours.
