Endogenous demand responses for energy services, resulting from changing prices, have long been characterised in energy systems models. However, the uncertainty associated with such demand responses, modelled through the use of price elasticities, has often been ignored. This is problematic for...

This paper presents an analysis of climate policy instruments for the decarbonisation of the global electricity sector in a non-equilibrium economic and technology diffusion perspective. Energy markets are driven by innovation, path-dependent technology choices and diffusion. However,...

Integrated assessment models (IAMs) are a cornerstone of an effective approach to climate change mitigation. Despite the variety of methodologies for characterising the energy system, land use change, economics, and climate response, the modelling community has an open and urgent request for...

We perform a global case study to assess the implications of spatial resolution in electricity systems modelling. The global model PLEXOS-World is used to optimize the long-term capacity expansion and short-term operation of a global net-zero electricity system under alternative spatial...

Mathematical modelling and optimisation of the Distributed Energy Supply System (DESS) using natural gas, both at the building level and the overall energy supply network level was carried out for three types of micro-combined heat and power (micro-CHP) – solid oxide fuel cells, Stirling...

Energy system models based on experience curves are superior to conventional models in their treatment of the dynamics of technological development. However, assuming perfect foresight means that future learning rates are known with certainty, which is not realistic. An optimising model for the...

The European Union (EU) has pledged to reduce greenhouse gas (GHG) emissions until the year 2030 by 55% compared to 1990. Recently, the EU institutions decided to introduce a new Emission Trading System for road transport, buildings and fuels for additional sectors (ETS2) in addition to the...

Hybrid renewable energy systems have garnered considerable attention as sustainable power sources for remote off-grid islands in the Philippines. Consequently, they have been the subject of numerous techno-economic investigations. However, comprehensive explorations into the viability of 100 %...

Actions that transform our energy system are the cornerstone of decarbonizing our economy but have been hindered by the ineffective interface between researchers and decision-makers in Canada. This paper begins by arguing for a more holistic perspective on energy system decarbonization modelling...
