A systematic review of modelling methods for studying the integration of hydrogen into energy systems Open
Hydrogen could be generated, stored, transported, and consumed in various ways, making it a promising solution to carbon emission reduction. However, key questions still remain in how hydrogen could be appropriately integrated into energy …

Technoeconomic characterisation of low-carbon liquid hydrocarbons production Open
With growing attention on low-carbon fuels and chemicals to meet climate targets, careful cost and performance evaluations become critical. These hydrocarbons can be derived from biomass or hydrogen with captured CO2 via established pathwa…

Global energy scenarios: A geopolitical reality check Open
The ongoing Global Energy System Transformation (GEST) has attracted the attention of multiple academic disciplines and practitioners, approaching the process with different analytical and conceptual tools. We explore the ‘integration gap’…

A technical evaluation to analyse of potential repurposing of submarine pipelines for hydrogen and CCS using survival analysis Open
The UK oil and gas sector is mature and a combination of a dwindling resource base and a move towards decarbonisation has led to lower investments and an increasing decommissioning bill. Many existing offshore assets are in the vicinity of…

Comment on “How green is blue hydrogen?” Open
This paper is written in response to the paper “How green is blue hydrogen?” by R. W. Howarth and M. Z. Jacobson. It aims at highlighting and discussing the method and assumptions of that paper, and thereby providing a more balanced perspe…

The role of new nuclear power in the UK's net-zero emissions energy system Open
Swift and deep decarbonisation of electricity generation is central to enabling a timely transition to net-zero emission energy systems. While future power systems will likely be dominated by variable renewables (VRE), studies have identif…

Centralized vs. distributed energy storage – Benefits for residential users Open
Distributed energy storage is a solution for balancing variable renewable energy such as solar photovoltaic (PV). Small-scale energy storage systems can be centrally coordinated to offer different services to the grid, such as balancing an…
View article: Review of the Scottish TIMES energy system model
Review of the Scottish TIMES energy system model Open
The Scottish TIMES model has provided influential evidence to inform Scottish Government climate policy in recent years. This report presents the findings of a technical review of the Scottish TIMES model. This comprised a review of the mo…

Uncertainties, sensitivities and robustness of simulated water erosion in an EPIC-based global gridded crop model Open
Water erosion on arable land can reduce soil fertility and agricultural productivity. Despite the impact of water erosion on crops, it is typically neglected in global crop yield projections. Furthermore, previous efforts to quantify globa…

The role of bioenergy for global deep decarbonization: CO<sub>2</sub> removal or low‐carbon energy? Open
Bioenergy is expected to have a prominent role in limiting global greenhouse emissions to meet the climate change target of the Paris Agreement. Many studies identify negative emissions from bioenergy generation with carbon capture and sto…

Measuring inefficiency in international electricity trading Open
Interconnectors reduce the cost of electricity supply if they are operated efficiently. We show that established metrics used to monitor electricity trading inefficiency become increasingly inaccurate in several trading conditions. We devi…

The private and social value of British electrical interconnectors Open
Interconnectors have increasing value for Britain in providing access to cheaper Continental power, security of supply, and managing increased renewables penetration. Their value has induced proposals for substantial new interconnectors. T…
