Today CCS technology chain is fundamental to reach the environmental target, in particularly for the CO2 emissions from "hard-to-abate" industries. To make CCS chain more effective and reduce costs, it is mandatory to explore new approaches, in a strongly multidisciplinary approach.
The R&D environment can facilitate the creation of place where needs and opportunities can be better identified when well integrated with business and field application. In Eni, an R&D CCS Platform "eCCSlens" has been created, in which different competences are shared and cross contamination is encouraged.
In this paper, an integrated workflow is presented, with a particular focus in the example of "boundary" optimization:
• Integration between capture technologies, compression, transport routing and design, considering requirements defined by the local geography and characteristics of the sources and stores
• Merge of modelling of transport in wells and surface facilities
• A G&G integrated workflow leading to a complete modelling of the reservoir in tight connection with the Measuring, Monitoring and Verification (MMV) plan
• A tool to estimate the CAPEX and OPEX costs of different scenarios within a CCS initiative
Since pre-industrial times, the atmospheric concentration of several greenhouse gases (as CO2, methane and nitrous oxides) has increased substantially. The stability of our climate is directly linked to the atmosphere, so variations in the level, or concentration, of any greenhouse gas will have an impact.
Atmospheric levels of CO2 are now higher than at any time in the past 800,000 years, reaching 400 parts per million (ppm) in early 2013, compared to a pre-industrial high of 280 ppm. Reducing man-made CO2 emissions, including those produced through the burning of fossil fuels, is a key element in mitigating greenhouse gas emissions and the dangerous effects of climate change.
Why we need CCS, to which IEA attributes a 12÷15% contribution to the zeroing of the CO2 emission in the next 30 to 50 years:
