  • China’s Energy revolution strategy into 2030
    Resources Conservation and Recycling, 2018
    Co-Authors: Qilin Liu, Qi Lei, Jiahai Yuan
    Abstract:

    The Chinese Government just released its Energy Revolution Strategy (2016–2030) as an official policy response to President Xi Jinping’s urge. Withdraw of the US from Paris Climate Agreement has turned the global focus on if China can comply with its climate change commitments. The purpose of this paper is to conduct a comprehensive assessment on this utterly important question. We find that the 2030 Strategy is consistent with the GDP CO2 intensity target but cannot deliver CO2 peak earlier than 2030. We also explore the possibility for China to realize leapfrog in Energy efficiency and contribute more to global society in CO2 emissions abatement. Given China’s economic restructuring potential, continuous efforts in Energy efficiency could lead to much lower Primary Energy Demand than the Strategy proposed and thus peak Energy-related CO2 emissions around 2020. It can also make China a new champion in the world with highest Energy efficiency level at comparable income level during the economic development process. A much lower Primary Energy Demand can also facilitate China’s non-fossil Primary Energy share target and the low-carbon power system transition.

  • Well-to-wheel costs, Primary Energy Demand, and greenhouse gas emissions for the production and operation of conventional and alternative vehicles
    Transportation Research Part D-transport and Environment, 2016
    Co-Authors: Mashael Yazdanie, Fabrizio Noembrini, Augusto Espinel, Steve Heinen, Konstantinos Boulouchos
    Abstract:

    Abstract This study provides a comprehensive comparison of well-to-wheel (WTW) Energy Demand, WTW GHG emissions, and costs for conventional ICE and alternative passenger car powertrains, including full electric, hybrid, and fuel cell powertrains. Vehicle production, operation, maintenance, and disposal are considered, along with a range of hydrogen production processes, electricity mixes, ICE fuels, and battery types. Results are determined based on a reference vehicle, powertrain efficiencies, life cycle inventory data, and cost estimations. Powertrain performance is measured against a gasoline ICE vehicle. Energy carrier and battery production are found to be the largest contributors to WTW Energy Demand, GHG emissions, and costs; however, electric powertrain performance is highly sensitive to battery specific Energy. ICE and full hybrid vehicles using alternative fuels to gasoline, and fuel cell vehicles using natural gas hydrogen production pathways, are the only powertrains which demonstrate reductions in all three evaluation categories simultaneously (i.e., WTW Energy Demand, emissions, and costs). Overall, however, WTW emission reductions depend more on the Energy carrier production pathway than on the powertrain; hence, alternative Energy carriers to gasoline for an ICE-based fleet (including hybrids) should be emphasized from a policy perspective in the short-term. This will ease the transition towards a low-emission fleet in Switzerland.

  • a comparative analysis of well to wheel Primary Energy Demand and greenhouse gas emissions for the operation of alternative and conventional vehicles in switzerland considering various Energy carrier production pathways
    Journal of Power Sources, 2014
    Co-Authors: Mashael Yazdanie, Fabrizio Noembrini, Lionel Dossetto, Konstantinos Boulouchos
    Abstract:

    This study provides a comprehensive analysis of well-to-wheel (WTW) Primary Energy Demand and greenhouse gas (GHG) emissions for the operation of conventional and alternative passenger vehicle drivetrains. Results are determined based on a reference vehicle, drivetrain/production process efficiencies, and lifecycle inventory data specific to Switzerland. WTW performance is compared to a gasoline internal combustion engine vehicle (ICEV). Both industrialized and novel hydrogen and electricity production pathways are evaluated. A strong case is presented for pluggable electric vehicles (PEVs) due to their high drivetrain efficiency. However, WTW performance strongly depends on the electricity source. A critical electricity mix can be identified which divides optimal drivetrain performance between the EV, ICEV, and plug-in hybrid vehicle. Alternative drivetrain and Energy carrier production pathways are also compared by natural resource. Fuel cell vehicle (FCV) performance proves to be on par with PEVs for Energy carrier (EC) production via biomass and natural gas resources. However, PEVs outperform FCVs via solar Energy EC production pathways. ICE drivetrains using alternative fuels, particularly biogas and CNG, yield remarkable WTW Energy and emission reductions as well, indicating that alternative fuels, and not only alternative drivetrains, play an important role in the transition towards low-emission vehicles in Switzerland.

  • Global warming potential of hydrogen and methane production from renewable electricity via power-to-gas technology
    The International Journal of Life Cycle Assessment, 2015
    Co-Authors: Gerda Reiter, Johannes Lindorfer
    Abstract:

    Purpose Power-to-gas technology enables storage of surplus electricity from fluctuating renewable sources such as wind power or photovoltaics, by generating hydrogen (H2) via water electrolysis, with optional methane (CH4) synthesis from carbon dioxide (CO2) and H2; the advantage of the latter is that CH4 can be fed into existing gas infrastructure. This paper presents a life cycle assessment (LCA) of this technological concept, evaluating the main parameters influencing global warming potential (GWP) and Primary Energy Demand. Methods The conducted LCA of power-to-gas systems includes the production of H2 or CH4 from cradle to gate. Product utilization was not evaluated but considered qualitatively during interpretation. Material and Energy balances were modeled using the LCA software GaBi 5 (PE International). The assessed impacts of H2 and CH4 from power-to-gas were compared to those of reference processes, such as steam reforming of natural gas and crude oil as well as natural gas extraction. Sensitivity analysis was used to evaluate the influence of the type of electricity source, the efficiency of the electrolyzer, and the type of CO2 source used for methanation. Results and discussion The ecological performance of both H2 and CH4 produced via power-to-gas strongly depends on the electricity generation source. The assessed impacts of H2 production are only improved if GWP of the utilized electricity does not exceed 190 g CO2 per kWh. Due to reduced efficiency, the assessed impacts of CH4 are higher than that of H2. Thus, the environmental break-even point for CH4 production is 113 g CO2 per kWh if utilized CO2 is treated as a waste product, and 73 g CO2 per kWh if the CO2 separation effort is included. Electricity mix of EU-27 countries is therefore not at all suitable as an input. Utilization of renewable H2 and CH4 in the industry or the transport sector offers substantial reduction potential in GWP and Primary Energy Demand. Conclusions H2 and CH4 production through power-to-gas with electricity from renewable sources, such as wind power or photovoltaics, offers substantial potential to reduce GWP and Primary Energy Demand. However, the input of electricity predominately generated from fossil resources leads to a higher environmental impact of H2 and CH4 compared to fossil reference processes and is not recommended. As previously bound CO2 is re-emitted when CH4 is utilized for instance in vehicles, the type of CO2 source and the allocation method have a significant influence on overall ecological performance.
