Recent Challenges and Development of Technical and Technoeconomic Aspects for Hydrogen Storage, Insights at Different Scales; A State of Art Review
May 2024
Publication
The importance of the energy transition and the role of green hydrogen in facilitating this transition cannot be denied. Therefore it is crucial to pay close attention to and thoroughly understand hydrogen storage which is a critical aspect of the hydrogen supply chain. In this comprehensive review paper we have undertaken the task of categorising and evaluating various hydrogen storage technologies across three different scales. These scales include Read More
Perspectives and Prospects of Underground Hydrogen Storage and Natural Hydrogen
Jun 2022
Publication
Hydrogen is considered the fuel of the future due to its cleaner nature compared to methane and gasoline. Therefore renewable hydrogen production technologies and long-term affordable and safe storage have recently attracted significant research interest. However natural underground hydrogen production and storage have received scant attention in the literature despite its great potential. As such the associated formation mechanisms g Read More
Levelised Cost of Transmission Comparison for Green Hydrogen and Ammonia in New-build Offshore Energy Infrastructure: Pipelines, Tankers, and HVDC
Mar 2024
Publication
As the global market develops for green hydrogen and ammonia derived from renewable electricity the bulk transmission of hydrogen and ammonia from production areas to demand-intensive consumption areas will increase. Repurposing existing infrastructure may be economically and technically feasible but increases in supply and demand will necessitate new developments. Bulk transmission of hydrogen and ammonia may be effected by dedicated pi Read More
Thermodynamic Modelling and Optimisation of a Green Hydrogen-blended Syngas-fueled Integrated PV-SOFC System
Sep 2023
Publication
Developing an effective energy transition roadmap is crucial in the face of global commitments to achieve net zero emissions. While renewable power generation systems are expanding challenges such as curtailments and grid constraints can lead to energy loss. To address this surplus electricity can be converted into green hydrogen serving as a key component in the energy transition. This research explores the use of renewable solar energy for Read More
A Techno-economic Analysis of Global Renewable Hydrogen Value Chains
Jul 2024
Publication
Many countries especially those with a high energy demand but insufficient renewable resources are currently investigating the role that imported low carbon hydrogen may play in meeting future energy requirements and emission reduction targets. A future hydrogen economy is uncertain and predicated on reduced price of hydrogen delivered to customers. Current hydrogen production steam reforming of natural gas or coal gasification is co-located Read More
A Physics Constrained Methodology for the Life Cycle Assessment of Sustainable Aviation Fuel Production
May 2024
Publication
Feedstock-to-fuel conversion or “Fuel Production” is a major contributor to greenhouse gas (GHG) emissions in life cycle assessment (LCA) of sustainable aviation fuels (SAF) from wastes. Here we construct and demonstrate an original mass and energy conserved chemically rigorous LCA methodology for the production of Hydroprocessed Esters and Fatty Acids-Synthetic Paraffinic Kerosene (HEFA-SPK) from Used Cooking Oil (UCO). This study proposes Read More
Green Hydrogen Integration in Aluminium Recycling: Techno-economic Analysis Towards Sustainability Transition in the Expanding Aluminium Market
Feb 2024
Publication
The use of aluminum-based products is widespread and growing particularly in industries such as automotive food packaging and construction. Obtaining aluminum is expensive and energy-intensive making the recycling of existing products essential for economic and environmental viability. This work explores the potential of using green hydrogen as a replacement for natural gas in the smelting and refining furnaces in aluminum recycling facilities. The Read More
An Assessment of Decarbonisation Pathways for Intercontinental Deep-sea Shipping Using Power-to-X Fuels
Aug 2024
Publication
Shipping corridors act as the arteries of the global economy. The maritime shipping sector is also a major source of greenhouse gas emissions accounting for 2.9% of the global total. The international nature of the shipping sector combined with issues surrounding the use of battery technology means that these emissions are considered difficult to eliminate. This work explores the transition to renewable fuels by examining the use of electrofuels (in the for Read More
Palm Trees, Energy Security and Green Hydrogen Futures: Tourists' Views on Mallorca's Low Carbon Transition
Jan 2025
Publication
The development of green hydrogen can provide a welcome boost in energy security particularly for island nations that may be reliant on energy imports or intermittent renewables as part of their energy transition. However the expansion of a green hydrogen economy may have social environmental and economic impacts on tourism-reliant islands which may not be accounted for using typical market assessments. In this study focus groups and an Read More
Policy Supports for the Deployment of Solar Fuels: Islands as Test-beds for a Rapid Green Transition
May 2023
Publication
Coastal areas particularly islands are especially vulnerable to climate change due to their geographic and climate conditions. Reaching decarbonisation targets is a long process which will require radical changes and ‘out of the box’ thinking. In this context islands have become laboratories for the green transition by providing spaces for exploring possibilities and alternatives. Here we explore how hydrogen (H2) energy technologies can be a critical Read More
