الوصف: This study applies a partial equilibrium forest sector model to analyse the impacts of biofuel deployment for road transport in the Nordic countries, when alternative use of the biomass resources and transport sector electrification are considered. We foresee a strong electrification of the transport sector, resulting in a demand for biofuels of approximately 2.5 billion L in 2035 and 1 billion L in 2050 in a 100% fossil-free base scenario. The simultaneous increase in demand from pulping industries and biofuel will cause an overall increase in wood use, of which the biofuels share will constitute approximately 20–25%. The utilization of harvest residues will increase more than 300% compared to the current level, since biofuel production will reallocate some of the current raw material used in district heating. Biofuel consumption in road transport will likely reduce after 2040 due to increasing electrification, but it is plausible that the declining domestic demand will be replaced by increasing demand from international biofuel markets in aviation and shipping. The main uncertainties in the scenarios are the future costs and profitability of forest-based biofuel technologies and the public acceptance of the close to 100 TWh of new renewable electricity production needed for the electrification of Nordic road transport.

الوصف: We investigate the bioelectricity potential of South Korea and the ramifications of the introduction of biomass use in electricity production for the Korean electricity market. The novelty of our study lies in that we consider a broad portfolio of biomass-energy technologies and carefully analyze their potential economic and environmental implications for South Korea given its biomass availability. To the best of our knowledge, this is the first study to attempt this in the context of South Korea. We first offer a preliminary assessment of South Korea&rsquo
s theoretical biomass potential from forestry residues, livestock manure, and staple crops and of the amount of electricity that could be generated using these different biomass feedstocks. Our analysis suggests that biomass can be used to produce a substantial portion of the total electricity consumed annually in South Korea. In addition, out of all the feedstocks and technologies considered, pyrolysis of forestry residues could potentially impact the electricity market the most. Next, we simulate different bioelectricity supply shocks while randomly perturbing our model&rsquo
s demand and supply elasticity parameters using the Monte Carlo methodology. Our results demonstrate that the introduction of bioelectricity could significantly affect South Korea&rsquo
s electricity market as well as its CO2 emissions.وصف الملف: application/pdf

الوصف: Summarization: Biogas development is expected to contribute to the National Recovery and Resilience plan to overcome the COVID-19 shock. Estimation of the agricultural biogas potential in economic terms can contribute to refining policies inciting effective sector development. In this paper, we attempt to do so by modeling a biogas chain from dedicated crops and livestock waste. This was achieved by coupling farming models to the biogas industry in a partial equilibrium framework. This allows for a comprehensive investigation of alternative measures in technology, size, spatial distribution and land use change. The integrated model was implemented in Lubelskie for the previous policy (green certificates) and the current policy (auction market). In both cases, the bottom-up profit driven optimization resulted in approximately 40 MWel, which shows a robust economic potential more than four times the biogas sector’s actual capacity in the region, also providing the detailed structure of the sector. When focusing on the industry structure, both scenarios give similar results regarding 1–2 MWel plant size close to the observed situation. The model also suggests a large number of new facilities

الوصف: This paper examines transitioning to low carbon vehicles such as battery electric vehicles (BEVs), hydrogen fuel cell vehicles (FCVs), and natural gas vehicles (NGVs) for curbing greenhouse gas (GHG) emissions in Japan. Infrastructure development for fuel charging stations for BEVs, FCVs and NGVs and the carbon tax are evaluated as policy measures to promote these vehicle fleets as well as the reduction in the life cycle GHG emissions. Our analysis uses the newly developed Japanese multi-regional partial equilibrium system dynamics model UniSyD_JP. The energy supply sector consists of fossil fuels, nuclear energy, renewable energy and hydrogen and the nation's energy demand is projected by the expected population growth and the GDP outlook. The energy demand for the transport sector is endogenously determined by a consumer's vehicle choice characterized by the multinomial logit model. We examine five scenarios for different mixes of infrastructure development, carbon tax and projected oil price. The transition paths to a low carbon vehicle fleet are explored for the period of 2016–2060. We found that infrastructure development increases the penetration of FCVs and NGVs, but it will not reduce the life cycle GHG emissions. Significant emissions reduction requires both infrastructure development and high carbon taxes.

الوصف: Climate change is likely to affect water availability and therefore hydropower generation in many regions of the world. In drying regions, hydropower generation may be impaired, creating a need for new power investments that would otherwise have been unnecessary. In this study we apply two partial equilibrium models (GCAM and TIAM-ECN) and two general equilibrium models (MEG4C and Phoenix) to identify possible pathways of power sector adaptation for Colombia under climate change. We adopt two GCM projections that deteriorate hydropower generation over the next three decades, and simulate each for two radiative forcing scenarios (RCP8.5 and RCP4.5). Relative to Colombia's projected power demand growth over the coming decades, losses in hydropower generation are marginal. Nonetheless, climate-driven losses in hydropower must be compensated by alternative technologies´expansion, which vary significantly across models. When climate policy is implemented (RCP4.5), three distinct expansion pathways emerge: increased solar and wind energy (TIAM-ECN); significant power demand reductions (Phoenix and MEG4C); and increased fossil resources with carbon dioxide capture and storage (GCAM). We show the need to explore the tradeoffs/synergies among alternative expansion pathways and their potential impacts on other sectors (e.g. water and land), and for effective policies to incentivize their adoption in Colombia.

الوصف: The Generation Expansion Planning (GEP) stands as one as one of the most discussed topics within the academia and decision makers in the energy sector, especially related to meeting deep emission reduction targets. Every country, aiming at decarbonizing its economy, focuses on the application of policies that could enhance the penetration of Renewable Energy Sources (RES) in its power capacity mix. GEP is a complex task, combining techno-economic, financial, spatial and environmental characteristics. Several models are developed to model GEP, applying different methodological approaches. The underlying theory is very important as it might inherit bias in the resulted outcomes. The debate on the appropriateness of each methodology is increased, especially as projected outlooks deviate from reality. The paper aims to provide a review of the models employed to integrate RES in the GEP. The paper classifies models in three generic categories: optimisation models, general/partial equilibrium models and alternative models, not adopting the optimum integration of RES in the GEP. It provides insights on the characteristics, advantages and disadvantages of the theoretical approaches implemented, as well on their suitability for different aspects of the problem, contributing in the better understanding on the expected outcomes of each methodology.

الوصف: International audience; Bioenergy systems are promoted in an effort to mitigate climate change, and policies are defined accordingly to be implemented in the coming decades. Life Cycle Assessment (LCA) is used to assess the environmental performance of bioenergy systems, yet subject to the limitations of static approaches. In classical LCA, no temporal differentiation is undertaken: all inventoried instant to long-term greenhouse gases emissions (GHG) are aggregated and characterised in the same way, over a fixed time horizon, by means of fixed characterisation factors. Positive and negative impact contributions of dynamic biogenic carbon (Cbio) sum up to zero, yielding the same result as carbon neutral estimates. Climate mitigation results are biased without the temporal consideration of these flows. The purpose of the study is to highlight the time-sensitive potential climatic consequences of policy-driven transport strategies for metropolitan France, in the specific context of the dynamic LCA framework and climate change mitigation. We therefore propose a dynamic approach coupling a partial-equilibrium model (PEM) with dynamic Cbio models. The PEM analyses in detail the techno-economic performance of the metropolitan French energy-transport sector. It explores prospective optimization options (supply-demand equilibrium) of emerging commodity and energy process pathways in response to a policy in question. The Cbio model generates dynamic inventories of the Cbio embedded in the primary renewable biomass outputs of the PEM. It captures the dynamic Cbio exchange flows between the atmosphere and the technosphere over time: negative emissions from fixation (sequestration) and positive emissions from release (e.g. combustion or decay). A dynamic impact method is applied to evaluate the mitigation effects of Cbio from forest wood residues by comparing the climate change impacts from complete carbon (fossil + biogenic) with carbon neutral inventories across scenarios. Two sets of results are computed concerning the overall transport (all emissions) and bioethanol (wood-to-fuel emissions) systems. The mitigation effect from long-term historic sequestration allocated to bioethanol (462%) is significantly larger than for transport (3%), expressed as the difference with carbon neutral estimates. The fossil-sourced emissions from bioethanol production represents only 5.4%. In contrast, a comparison with an alternative reference scenario involving wood decay demonstrated higher impacts (i.e. an increase of 316%) than carbon neutral estimates. The representation of the actual climatic consequences depends on the chosen fixed end-year of the dynamic impact assessment. Moreover, the mitigation effect is proven sensitive to the rotation length of forestry wood: the shorter the length the lower the mitigation from using renewable forest resources. Other energy-policy scenarios, Cbio modelling approaches and consequences of indirect effects should be further studied and contrasted.

الوصف: We investigate the economic impacts of policies for coordinating electricity production in the Gulf Cooperation Council (GCC) through electricity trade. The GCC countries have installed a network of high-voltage transmission lines that links Saudi Arabia, Bahrain, Kuwait, Oman, Qatar, and the United Arab Emirates. The Interconnector has successfully provided reliability services but has not yet realized its full potential as a platform to fully integrate the individual electricity systems. We perform a static analysis of 2015 using a partial equilibrium model with detailed power generation and water production sectors for each country. We calculate economic losses and gains for each country and in aggregate before and after coordination through electricity trade. We first assess the potential gains from coordination subject to the existing national policies for fuel subsidies. We then consider coordination when fuel inputs are not subsidized. Finally, we devise a scenario that aims to retain the benefits of coordination without removing fuel subsidies. Our results indicate that subsidy removal is necessary for each country to gain from electricity trade. Removing fuel subsidies provides the bulk of economic gains: $42.6 billion. Utilizing the Interconnector further increases annual gains by $1.1 billion.

الوصف: This paper simulates the real household expenditure effects of large electricity price increases in Zambia. First, we find that electricity subsidies are highly regressive. The richest household quintile receives over 60% of the subsidies, while the poorest quintile receives less than 1%. Second, our partial equilibrium simulations of the welfare effects of a 75% electricity price increase show that the poorest households would experience a 3 times larger percentage loss in real expenditure compared to the wealthiest households. Naturally, these adverse effects lead to an increase in poverty. However, we find that transferring the fiscal savings realised from the complete elimination of electricity subsidies to the poor reduces extreme poverty significantly. This budget-neutral strategy is particularly attractive for Zambia, and other sub-Saharan economies currently battling the twin challenges of widening budget deficits and high extreme poverty.

الوصف: Greenhouse gas emission (GHGE) taxes on food products have recently been proposed as means to help reduce agricultural emissions. Numerous authors have calculated potential GHGE reductions in case such a tax was implemented in certain countries or regions. They did however assume a reduced production of GHGE-intense foods equal to the decline in demand induced by the tax. This omits however possible increases of net-exports that might offset such a demand reduction. Herein, the market dynamic behind this so-called “emission leakage” is explained and its effect quantified for a greenhouse gas tax in the European Union. We use the European Forest and Agricultural Sector Optimization Model for the quantitative analysis and simulate a greenhouse gas tax on all food products, based on their individual emission levels. The partial equilibrium model covers all world regions and hence the tax's effects on international trade of agricultural commodities can be examined. It was found that 43% of the greenhouse gas reduction indicted by a domestic consumption reduction is lost through emission leakage. This already includes the mitigating effects of a production shift from inefficient to efficient producers that is another consequence of increased exports from the European Union. A greenhouse gas emission tax on food products is hence much less efficient than previously proposed, if it is not introduced globally or trade is not restricted.
