| Summary/Abstract |
This study simulates a CO2 permit market in Romania using a dynamic general equilibrium model. The carbon constraint is set at 20.7% below the reference emissions level for sectors eligible according to the European Union Emission Trading Scheme (EU-ETS). Free permit distribution enhances growth despite a severe emissions cap, because environmental regulation stimulates structural changes [Porter, M., 1991. American's green strategy. Scientific American 264, 168]. That is, grandfathering allows sectors additional resources to invest in developing technologies, but it also raises the CO2 abatement costs because of energy rebound effects from enhanced growth. Results under endogenous growth [Romer, P.M., 1990. Endogenous technological change. Journal of Political Economy 98 (5), 71-102] are very similar to those obtained under an exogenous growth scenario [Ramsey, Y.F., 1928. A mathematical theory of saving. Economic Journal 38, 543-559], as the substitution effects are responsible for the majority of variations; in addition, Romanian research activities are too modest to significantly impact this system. The abatement cost per unit of GDP is higher under endogenous growth, as spillover effects reduce incentives to invest. Technological diffusion continues to have a positive impact on economic growth, which counterbalances the free-riding attitude adopted by some energy-intensive sectors, such as glass and cement.

| Summary/Abstract |
This study analyses battery electric vehicles (BEVs) in the future German power system and makes projections of the BEVs hourly load profile by car size ('mini', 'small', 'compact' and 'large'). By means of a power plant dispatching optimisation model, the study assesses the optimal BEV charging/discharging strategies in grid-to-vehicle (G2V) and vehicle-to-grid (V2G) schemes. The results show that the 2% rise in power demand required to power these BEVs does not hamper system stability provided an optimal G2V scheme is applied. Moreover, such BEV deployment can contribute to further integrating wind and solar power generation. Applying a V2G scheme would increase the capacity factors of base and mid-load power plants, leading to a higher integration of intermittent renewables and resulting in a decrease in system costs. However, the evaluation of the profitability of BEVs shows that applying a V2G scheme is not a viable economic option due to the high cost of investing in batteries. Some BEV owners would make modest profits (€6 a year), but a higher number would sustain losses, for reasons of scale. For BEVs to become part of the power system, further incentives are necessary to make the business model attractive to car owners

| Summary/Abstract |
New projects using existing storage technologies such as Pumped Hydro Storage (PHS) face uncertainty due to the lack of clear business models. Market regimes have generally tended to embed storage and generators within the central management of operators with multiple assets such as the French EdF (Electricité de France). By means of back-casting, this study depicts the role of storage in the power market, within the vertical integration in the governance portfolio of EdF. A dynamic algorithm simulates hourly operation under two different storage strategies, daily and weekly, and the results are compared with actual patterns over the period 2015–2019. This reveals missing money for a stand-alone player due to price arbitrage caused by low spread, and missing market opportunities. This suggests that the economics of storage are not driven by spot prices alone, but by other services, such as the energy block provision in support of nuclear power. Differential calculus is used to estimate the value of flows integrating the duration of storage and its seasonality. These findings further support the French regulator to install new PHS despite the lack of profitability, by means of capacity-energy hybrid contracts for new competitors in place of the existing government-industry structure.
