Thermal Energy Storage: Climate Change Mitigation Solution?
2011 (English)In: International Conference for Sustainable Energy Storage, Belfast, UK: University of Ulster , 2011Conference paper (Refereed)
Environmental well being and technology development are on the verge of collapsing. It has been asserted by IPCC that 30% of fauna and flora will face extinction by mid 21st century in the pursuit of business as usual path with current economic development pace. In order to minimize the anthropogenic related damage to the environment, a maximum level of 450ppm CO2 emission has to be maintained at all cost. Technologies that provide climate change mitigation solution and economic growth are hence the highlight; thermal energy storage (TES) is one among them. Energy storage provides the possibility to shift load from on peak energy demand to off peak thermal and electricity production, this results in lower energy flux in the system and therefore cuts down the marginal thermal and electricity production. This reduction in peak power demand translates to a decrease in marginal power production which, in today’s fossil fuel based economy, often pars with auxiliary and high carbon emitting thermal and electric power plants. This study provides a scenario analysis which quantifies the environmental benefit of TES implementation for the Swedish energy system. In the studied scenario, thermal energy storage will be implemented to the existing energy grid to alleviate peak electric and thermal power demand. The rate of implementation is paired with decrease in technology cost, reproduced from typical Learning Curve Model. The study shows that for the Swedish energy system, the total amount of fossil fuel used in heating of residential and service sectors is 19TWh, while reduction that can be achieved cost effectively with implementation of TES amounts to 2.5TWh. This corresponds to a Green House Gas (GHG) emission reduction of 620kton/year or 13% of total fossil fuel based emissions from heating in residential and service sectors.
