We extend the WITCH model to consider the possibility to produce and trade electricity generated by large scale concentrated solar power plants in highly productive areas that are connected to the demand centres through High Voltage Direct Current (HVDC) cables. We find that it becomes optimal...

We build a system dynamics model to evaluate the potential dynamics of consumer adoption of “Smart Energy Behaviour”. Within this term we include different levels of: i) shift in electricity consumption towards less costly-less polluting and congestioning hours; ii) the reduction of mainly...

This paper analyzes the future prospects of carbon capture technologies. The first part of the analysis presents and discusses the results of an expert elicitation survey on a broad range of carbon capture options. The survey collected probabilistic estimates on the future values of energy...

In this paper we compare the results of two different expert elicitation methods: in-person interviews and a self-administered web-based survey. Traditional expert elicitation has been done face to face, with an elicitor meeting with an expert for a few hours to several days, depending on the...

We assess the optimality of investments in power grid innovation, under both technological options of Super and Smart Grids, using the WITCH model in the version that includes Super-Grids. Super Grids allow producing and trading of electricity generated by large scale concentrated solar power...

Many non-market valuation models, such as the Ricardian model, have been estimated using cross sectional methods with a single year of data. Although multiple years of data should increase the robustness of such methods, repeated cross sections suggest the results are not stable. We argue that...

The paper examines future energy and emissions scenarios in China, presenting historical data and scenarios generated using the Integrated Assessment Model WITCH. A Business-as-Usual scenario is compared with four scenarios in which Greenhouse Gases emissions are taxed, at different levels. Key...

This paper analyses the incentives to participate in and the stability of international climate coalitions. Using the integrated assessment model WITCH, the analysis of coalitions’ profitability and stability is performed under alternative assumptions concerning the pure rate of time...

WITCH - World Induced Technical Change Hybrid - is a regionally disaggregated hard link hybrid global model with a neoclassical optimal growth structure (top down) and a detailed energy input component (bottom up). The model endogenously accounts for technological change, both through learning...

In this paper we use the hybrid integrated model WITCH to quantify and analyze the investments and financial flows stimulated by a climate policy to stabilize Greenhouse Gases concentrations at 550ppm CO2-eq at the end of the century. We focus on investments to decarbonize the power sector and...
