A pressing question facing policy makers today in developing a long-term strategy to manage carbon emissions from the electric power sector is how to appropriately balance investment in R&D for driving innovation in emerging low-and zero-carbon technologies with investment in commercially available technologies for meeting existing energy needs. Likewise, policy makers need to determine how to allocate limited funding across multiple technologies. Unfortunately, existing modeling tools to study these questions lack a realistic representation of electric power system operations, the innovation process, or both. In this paper, we present a new modeling framework for long-term R&D and electricity generation capacity planning that combines an economic representation of endogenous non-linear technical change with a detailed representation of the power system. The model captures the complementary nature of technologies in the power sector; physical integration constraints of the system; and the opportunity to build new knowledge capital as a non-linear function of R&D and accumulated knowledge, reflective of the diminishing marginal returns to research inherent in the energy innovation process. Through a series of numerical experiments and sensitivity analyses - with and without carbon policy - we show how using frameworks that do not incorporate these features can over-or under-estimate the value of different emerging technologies, and potentially misrepresent the cost-effectiveness of R&D opportunities.

Energy R&D Investments and Emissions Abatement Policy

The study examines the interactions of the energy R&D investments and the CO2 abatement policy using an endogenous energy R&D climate-economy model. Energy R&D investments affect the carbon emissions directly through efficiency improvements and indirectly by changing the comparative advantages of resources. This study considers the R&D investments in energy efficiency and low-carbon technology and explores how energy R&D investments accelerate the energy transition from fossil fuels to low-carbon technology. Three policies of carbon abatements are considered, namely, the optimal policy, the 2 °C policy, and the 1.5 °C policy. From the perspectives of benefits and costs, the optimal policy leads to the least abatement costs compared to the other two abatement policies. This study indicates that the more restrictive the abatement policy is, the more severe economic damage is caused in the short run, but more economic welfare is gained in the long run.
