Background • The need to update energy policies worldwide in order to deal with climate change is now unanimously considered a priority. Paramount is an approach integrating energy usage and production. Such an approach requires a transition towards an economy not any longer based on fossil fuels, but on an increased demand/supply efficiency and on renewable sources, while aiming at clean technologies and emissions close to zero. • The International Energy Agency (IEA) has agreed that the world’s energy demand will rise by 1. 8% per year, falling back upon coal for over 1/3 of the total growth. In 2030, 97% of the forecasted emission increment will be due to non-OECD countries (3/4 of which in China, India and Middle East Countries). Therefore the energy and research policy must take the following factors into account: • a) fossil fuel demand will stay very high in the coming decades, above all in the Countries with an Emerging Economy; • b) the development and widespread commercial deployment of zero emission technologies at a competitive cost will take longer; • c) it is necessary to act to reduce the emissions into the atmosphere that fossil fuel usage will still bring about.

Background • IEA reckons that CCS techniques could contribute to reduce CO 2 emissions by about 20% by 2050 in a scenario where at that time emissions will be 50% lower than today’s levels. Source: http: //www. iea. org

Background • Regarding the regulatory aspects, many positive steps have been made on the international level to include CCS techniques into the London Protocol on marine pollution and into the OSPAR Treaty for the protection of the marine environment in the N-E Atlantic. • The regulatory framework is destined to evolve rapidly, above all thanks to the recent European Directive 2009/31/EC of 23 April 2009 on CO 2 Geological Storage 2, which binds the member states to report on the implementation state of the Directive at national level by June 2011.

Public acceptance • Recent research indicates that more than 90% of the population is considering greenhouse effect mitigation an important factor to pursue with determination because of its implications on climate change. However most of the people are not fully aware of the potential of CCS. • The lack of awareness of the population regarding CCS makes it imperative that correct information from reliable sources is made available to the public. • A communication strategy addressing a wide and varied group of people to whom CCS is a concern is essential to prevent positions which are extremely anti-CCS, irrational or effectively opposing the objective from monopolizing the debate.

CCS challenges • CCS techniques have a strong potential for the reduction of CO 2 emissions. The objectives of the activity in the next few years can be summarized as follows: • a) lowering the cost of CCS to values < 30 -40 €/t CO 2; • b) reducing the investment and running costs of CCS installation; • c) reducing the added energy required by CCS technologies; • d) completing the mapping of geological sites suitable for CCS in Europe and in Italy; • e) starting CCS demonstration projects on an industrial scale; • f) supporting the European states in implementing the European Directive on CO 2 Geological Storage.

Main projects under way • ENEL – Geological storage in saline aquifers. This demonstrative project is conceived with the aim of evaluating the potential for CCS in Italy, with special regard to the areas located near the ENEL power plants of Civitavecchia, Brindisi and Porto Tolle. The construction of a 0. 8 MNm 3/h CCS installation treating part of the flue gases of a 660 MWe unit of the Porto Tolle power plant will follow. About 1 Mt/year of CO 2 will be transported to an offshore saline aquifer and injected underground.

Main projects under way • ENI – Feasibility study and pilot project of injection into a depleted hydrocarbon field. ENI is installing the surface infrastructure for CO 2 injection and monitoring in the Cortemaggiore gas field. The injection of 8000 t/yr of CO 2 will follow over a 3 year period, followed by 2 years of post injection monitoring. Studies on the utilization of the CO 2 will also be run in order to increase the recovery factor from Italian hydrocarbon fields.

Main projects under way • ENI-ENEL – Agreement for the development of CCS techniques. The agreement involves a joint study on the potential for CO 2 geological storage in Italy and the implementation of the first Italian CCS project. ENEL is busy with the construction of a pilot CO 2 post-combustion capture installation; the CO 2 will be liquefied in situ and transported to Cortemaggiore, where ENI will inject it into the depleted field. A joint study for a CCS demonstration project of 1 Mt/year is also involved.

Main projects under way • CARBOSULCIS – CBM and ECBM methane recovery and CO 2 storage ( Sulcis). The project has the objective of evaluating the feasibility of methane recovery and of CO 2 storage (ECBM) in vast parts of the Sulcis coal basin, Sardinia, which are not suitable for mining activities. Once the characterization of the basin has been completed through studies, analyses of existing data and experimentation, the second stage will follow, with the aim of defining all the remaining aspects for the construction of a pilot injection and storage installation.

Main projects under way • ENEL – CO 2 capture demonstration projects. 1 - post-combustion capture project = construction of a pilot plant of 10. 000 Nm 3/h to be installed at the Brindisi coal power plant. The CO 2 produced will be stored at ENICortemaggiore. A 0. 8 MNm 3/h installation will be constructed to treat part of the flue gases of a 660 MWe unit of the Porto Tolle power plant. 2 - “flameless” combustion of coal in atmosphere of O 2, CO 2 and water vapour, (1500 to 1700 °C and P> 4 bar). Process developed and licensed to ITEA, used now on a 5 MWt pilot plant, will be tested on a 48 MWe plant.

Main projects under way • TECHINT – Post-combustion CCS on gas fired power installation. The main goal is to apply post-combustion CO 2 capture to an existing 120 MWe gas fired cogenerative power installation operated by Tenaris at Dalmine steel industry; the feasibility study is finalized. • TECHINT – Pre-combustion pilot installation at Sotacarbo research centre (PRATO Project). The main goal is the design and construction of a pilot installation for pre-combustion CO 2 capture to be located in the research area of Sotacarbo (Sardinia); the feasibility study has already been finished.

Main projects under way • ENEA – Clean coal/zero emission project. Develop and demonstrate pre-combustion carbon capture technology, applied to a coal fired system, and CO 2 storage in coal beds (ECBM) and in saline aquifers. A pilot installation for the combined generation of electricity and hydrogen will be constructed in the research area of Sotacarbo (Sardinia). The captured CO 2 will be injected into coal beds managed by Carbosulcis and into the underlying aquifers. ENEA is part of the industrial demonstrative initiatives as well as in the aforementioned projects managed by Techint and in ENEL’s oxycombustion project.

Main projects under way • MSE-Lombardia Region agreement for the development of CCS techniques. A recent agreement (Feb. 2010), between MSE and Lombardia Region, promotes joint studies on the potential for CO 2 storage in Lombardia: the largest Italian CO 2 producer. The agreement is also finalized: 1) to foster voluntary agreements between industrial partners, research Institutes (public and/or private), and Universities; 2) to promote the processes involved with authorizative issues and public acceptability; 3) to promote a CCS pilot plant, also in order to transfer administrative competencies from the Italian government to Regional Authorities.
