Incorporating Safety-II in future gas systems

This article studies safety management in future gas systems. It is structured around the compatibility of its technological and institutional coordination. We identify how the current mode of safety management is not in harmony with increasingly complex technological and institutional arrangements, and combine safety science with...

Strategic uses for ancillary bioenergy in a carbon-neutral and fossil-free 2050 European energy system

Biomass is a growing renewable energy source in Europe and is envisioned to play a role for realising carbon neutrality, predominantly using dedicated energy crops. However, dedicated biomass is controversial for reasons including its competition with food production or its land-use and emissions impacts. Here we examine the potential role of a...

On the discovery and enactment of positive socio-ecological tipping points: insights from energy systems interventions in Bangladesh and Indonesia

Notions, such as leverage points, sensitive interventions, social tipping points, transformational tipping points, and positive tipping points, are increasingly attracting attention within sustainability science. However, they are also creating confusion and unresolved questions about how to apply these concepts when dealing with urgent...

Design principles for efficient photoelectrodes in solar rechargeable redox flow cell applications

Recent advances in photoelectrochemical redox flow cells, such as solar redox flow batteries, have received much attention as an alternative integrated technology for simultaneous conversion and storage of solar energy. Theoretically, it has been reported that even single- photon devices can demonstrate unbiased photo-charging with high solar-to...

Warping NMPC for online generation and tracking of optimal trajectories

Generation of feasible and optimal reference trajectories is crucial in tracking Nonlinear Model Predictive Control. Especially, for stability and optimality in presence of a time varying parameter, adaptation of the tracking trajectory has to be implemented. General approaches are real-time generation of trajectories or switching between a...

The geopolitics of renewables; exploring the political implications of renewable energy systems

This paper explores the potential political implications of the geographic and technical characteristics of renewable energy systems. This is done through a thought experiment that imagines a purely renewable based energy system, keeping all else equal. We start by noting that all countries have access to some form of renewable energy, though...
