This paper seeks to decry the notion of a single solution or “silver bullet” to replace petroleum products with renewable transport fuel. At different times different technological developments have been in vogue as the panacea for future transport needs: for quite some time hydrogen has been perceived as a transport fuel that would be all encompassing when the technology was mature. Liquid biofuels have gone from exalted to unsustainable in the las Read More

The global energy transition towards a carbon neutral society requires a profound transformation of electricity generation and consumption as well as of electric power systems. Hydrogen has an important potential to accelerate the process of scaling up clean and renewable energy however its integration in power systems remains little studied. This paper reviews the current progress and outlook of hydrogen technologies and their application in power Read More

To improve the utilization rate of the energy industry and reduce high energy consumption and pollution caused by coal chemical industries in north western China a planning scheme of a wind‐coal coupling energy system was developed. This scheme involved the analysis method evaluation criteria planning method and optimization operation check for the integration of a comprehensive evaluation framework. A system was established to plan the tota Read More

Hydrogen produced from renewable electricity will play an important role in deep decarbonisation of industry. However adding large electrolyser capacities to a low-carbon electricity system also increases the need for additional electricity generation from variable renewable energies. This will require hydrogen production to be variable unless other sources provide sufficient flexibility. Existing sources of flexibility in hydro-thermal systems are hydropower Read More

Due to their environmental protection and high power generation efficiency the control technology of hydrogen fuel cells (HFCs) connected to the microgrid has become a research hotspot. However when they encounter peak demand or transient events the lack of power cannot be compensated immediately by HFCs which results in sudden changes of the voltage and frequency. The improved virtual synchronous generator (VSG) control strategy based on Read More

Compact-tension (CT) specimens made of low alloy 30CrMo steels were hydrogen-charged and then subjected to the fracture toughness test. The experimental results revealed that the higher crack propagation and the lower crack growth resistance (CTOD-R curve) are significantly noticeable with increasing hydrogen embrittlement (HE) indexes. Moreover the transition in the microstructural fracture mechanism from ductile (microvoid coale Read More

Visible-light-driven hydrogen production through photocatalysis has attracted enormous interest owing to its great potential to address energy and environmental issues. However photocatalysis possesses several limitations to overcome for practical applications such as low light absorption efficiency rapid charge recombination and poor stability of photocatalysts. Here the preparation of efficient noble metal–semiconductor hybrid photocatalyst Read More

The objective of this paper is to derive for the first time decarbonization roadmaps for the ten nations of ASEAN. This study first presents a regional view of ASEAN’s fossil and renewable energy usage and energy-related CO2 emission. Results show that renewable energies have been losing ground to fossil energies in the last two decades and fossil fuels will likely continue to be an important part of ASEAN’s energy mix for the next few decades. There Read More

Producing hydrogen from water using a redox mediator on solid electrocatalyst particles in a reactor offers several advantages over classical electrolysis in terms of safety membrane degradation purity and flexibility. Herein vanadium-mediated hydrogen evolution on a commercial and low-cost Mo2C electrocatalyst is studied through the development of a reaction kinetics model. Based on a proposed mechanistic reaction scheme we establishe Read More

This standard has been created for the specific purposes of the Hy4Heat programme. The standard was commissioned in 2018 and this version was considered and approved by the relevant IGEM committees in May of 2020. This version of the standard was developed using the latest publicly available information at that time and may include some conservative requirements which further research may deem not necessary. The supplement will Read More
