Special Issue Information

Dear Colleagues,

I am excited to announce the new Special Issue entitled “Achieving Carbon Neutrality: Recent Progress of Sustainable Energy Economic, Energy Policy and Energy Transition—2nd Edition”.

As is well-known, the process of energy transition is in progress, albeit at different paces, with different underpinning strategies around the globe. As we approach the mid- and long-term energy transition goal years of 2030 and 2050, respectively, it is a good time to check in and assess the progress to date, and prospects for the future.

This Special Issue aims to consider how energy policies and economic initiatives aim to achieve carbon neutrality under the auspices of energy transition. We welcome submissions that consider system-wide analyses or analyses specific to individual sectors or technologies. The overarching theme here will be sustainability, i.e., the ability of these approaches to engender a sustainable energy transition.

This topic is strongly related to the journal’s scope, particularly with regard to sustainability evaluations and sustainable development in the areas of socio-economic and integrated approaches to sustainable energy system development. 

In this Special Issue, both original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Achieving a carbon neutral energy system via economic incentives.
  • Evaluation of social, economic and environmental impacts of energy transition policies.
  • Technological contributions to sustainable development and carbon neutral energy systems.
  • Sustainability evaluation metrics and frameworks.
  • Energy policy evaluation vis à vis the achievement of the SDGs and a carbon neutral future.

I look forward to receiving your contributions.

Aviation is widely recognised as one of the most carbon-intensive modes of transport and among the most challenging sectors to decarbonise. The use of green hydrogen (H2) in airside operations can help reduce emissions from air transport. While the pace and scalability of technology development, including H2-powered and ground support equipment, will be key factors, other financial, regulatory, legal, organisational, behavioural, and societal issues must also be considered. This paper investigates the key opportunities and challenges of using H2 in the aviation industry through eleven semi-structured interviews and a virtual expert workshop (N = 37) with key aviation industry stakeholders and academia. The results indicate that, currently, decarbonisation of the aviation sector faces several challenges, including socio-technical, techno-economic, and socio-political challenges, with socio-technical challenges being the most prominent barrier. This study shows that decarbonisation will not occur until the UK government is ready to have all the required infrastructure and capacity in place. Governments can play a significant role in directing the necessary ‘push’ and ‘pull’ to develop and promote zero-carbon emission aircraft in the marketplace and ensure safe implementation.
