Based on a comprehensive dataset, the paper develops a unique techno-economic market equilibrium model of CO 2 supply from emission sources and CO 2 demand from CO 2 -EOR to assess implications for a future CCTS infrastructure. The demand for "fresh" CO 2 for CO 2 -EOR operation is represented by an exponential storage cost function. In all scenarios of varying CO 2 and crude oil price paths the assumed CO 2 -EOR potential is fully exploited. CO 2 -EOR does add value to CCTS operations but the potential is very limited and does not automatically induce long term CCTS activity. If CO 2 prices stay low, little further use of CCTS can be expected after 2035. Terms of use: Documents in

The Impact of Renewable Energy Sources on the Czech Electricity Transmission SystemThis paper provides the first academic economic simulation analysis of the impact of increase in predominantly German wind and solar energy production on the Czech electricity transmission network. To assess the exact impact on the transmission grid, updated state-of-the-art technoeconomic model ELMOD is employed. Two scenarios for the year 2025 are evaluated on the basis of two representative weeks. The first scenario is considered as baseline and models currently used production mix. The second scenario focuses on the effect of German Energiewende policy on the transmission networks as expected in 2025. The results confirm that in the context of Central Europe, higher feed-in of solar and wind power increases the total transport of electricity between the transmission system operator areas as well as the average load of lines and volatility of flows. Also, an increase in number of critical high-load hours is observable. Taking into account only the Czech transmission system, considerable rise both in transported volume and volatility are observed only on border transmission lines, not inside the country. Moreover, our qualitative analysis shows that all these mentioned effects are strengthened by the presence of German--Austrian bidding zone.

Adequate extension of electricity transmission networks is required for integrating fluctuating renewable energy sources, such as wind power, into electricity systems. We study the performance of different regulatory approaches for network expansion in the context of realistic demand patterns and fluctuating wind power. In particular, we are interested in the relative performance of a combined merchant-regulatory price-cap mechanism compared to a cost-based and a non-regulated approach. We include both an hourly time resolution and fluctuating wind power. This substantially increases the realworld applicability of results compared to previous analyses. We show that a combined merchant-regulatory regulation, which draws upon a cap over the two-part tariff of the transmission company, leads to welfare outcomes superior to the other modeled alternatives. This result proves to be robust over a range of different cases, including such with large amounts of fluctuating wind power. We also evaluate the outcomes of our detailed model using the extension plans resulting from a simplified model based on average levels of load and wind power. We show that this distorts the relative performance of the different regulatory approaches. Terms of use: Documents in
