Hydrogen economy in Taiwan and biohydrogen

“…In this regard, extensive literature demonstrates the feasibility and effectiveness of using CGE or PE models to simulate future environmental burdens, although the proposed analyses were typically limited to the estimate of future carbon emissions without considering a full life cycle perspective (e.g., Bae and Cho, 2010;Chen et al, 2007;Dai et al, 2011;Strachan and Kannan 2008;Thepkhun et al, 2013;Zhou et al, 2013). Interestingly, Input-Output (IO) models were often used in combination with CGE or PE models, either as alternative to LCA or to strength the overall LCI for some specific technologies (see e.g., Dandres et al, 2012;Earles et al, 2013;Lee and Lee, 2008). Lee and co-authors (2011) and Mischke and Karlsson (2014) comprehensively illustrate the pros and cons of using CGE, PE, LCA and IO models to predict the environmental impacts at country's scale.…”

Combination of Equilibrium Models and Hybrid Life Cycle Input-Output Analysis to Predict the Environmental Impacts of Energy Policy Scenarios

Nowadays, many countries adopt an active agenda to mitigate the impact of greenhouse gas emissions by moving towards less polluting energy generation technologies. The environmental costs, directly or indirectly generated to achieve such a challenging objective, remain however largely underexplored. Until now, research has focused either on pure economic approaches such as computable general equilibrium (CGE) and partial equilibrium (PE) models, or on (physical) energy supply scenarios. These latter could be used to evaluate the environmental impacts of various energy saving or cleaner technologies via life cycle assessment (LCA) methodology. These modelling efforts have, however, been pursued in isolation, without exploring the possible complementarities and synergies. In this study, we have undertaken a practical combination of these approaches into a common framework: on the one hand, by coupling a CGE with a PE model, and, on the other hand, by linking the outcomes from the coupling with a hybrid inputoutput−process based life cycle inventory. The methodological framework aimed at assessing the environmental consequences of two energy policy scenarios in Luxembourg between 2010 and 2025. The study highlights the potential of coupling CGE and PE models but also the related methodological difficulties (e.g. small number of available technologies in Luxembourg, intrinsic limitations of the two approaches, etc.). The assessment shows both environmental synergies and trade-offs due to the implementation of energy policies. For example, despite the changes in technologies towards the reduction of greenhouse gas emissions, only marginal improvements are observed in the climate change mitigation scenario as compared to the business-as-usual. The energy related production and imports are indeed expected to increase over time and represent a large contribution to the country's impacts. Interestingly, side effects on other impacts than climate change or fossil resource depletion (e.g. ionising radiation and water depletion) may also occur mainly due to the use of nuclear energy in neighbouring countries.

“…Hydrogen is typically produced by steaming reforming, electrolysis, a biological method or other approaches [27]. Through comparative assessment of hydrogen production from all sources, biomass gasification has the best energetic and exergetic efficiencies [28].…”

“…The CGE model is suitable for evaluating the possible development of new energy, based on optimal behaviors of members in an economy with price adjustments, resources constraints, various production technologies and principles of market equilibrium. Evaluation of the impact of the development of a hydrogen economy requires a comprehensive economic energy model [5,6,8,27]. The dynamic GTAP model is a global CGE model [35] that was developed by Refs.…”
