The growing concern about climate change and the contemporary increase in mobility requirements call for faster cheaper safer and cleaner means of transportation. The retrofitting of fossil-fueled piston engine ultralight aerial vehicles to hydrogen power systems is an option recently proposed in this direction. The goal of this investigation is a comparative analysis of the environmental impact of conventional and hydrogen-based propulsive syst Read More

This paper presents an assessment of the levelized cost of clean hydrogen produced in Sicily a region in Southern Italy particularly rich in renewable energy and where nearly 50% of Italy’s refineries are located making a comparison between on-site production that is near the end users who will use the hydrogen and centralized production comparing the costs obtained by employing the two types of electrolyzers already commercially available. In the study Read More

A regional integrated energy system (RIES) synergizing multiple energy forms is pivotal for enhancing renewable energy use and mitigating the greenhouse effect. Considering that the equipment of the current regional comprehensive energy system is relatively simple there is a coupling relationship linking power generation refrigeration and heating in the cogeneration system which is complex and cannot directly meet various load demands. This article pro Read More

In this latest OIES podcast James Henderson talks to Bill Farren-Price the new Head of the Gas Programme about some of Key Themes identified by OIES research fellows for 2024. After a review of the outcomes from 2023 we look at the oil and gas markets and discuss a common theme around the contrast between the fundamental tightness in both markets compared with the relative softness of prices. We then move onto a number of energy transiti Read More

The current study presents a comprehensive investigation of different energy system configurations for a remote village community in India with entirely renewable electricity. Excess electricity generated by the systems has been stored using two types of energy storage options: lithium-ion batteries and green hydrogen production through the electrolysers. The hybrid renewable energy system (HRES) configurations have been sized by minimising the lev Read More

Hydrogen trade is an emerging area of interest for hydrogen developers end-users traders and governments around the world. It can enhance system flexibility energy security and clean growth enabling decarbonisation at a lower cost and faster pace. Thanks to its competitive advantage in existing ports terminals and interconnectors the UK is well placed to be the European trade hub for hydrogen and its carriers. With its access to world leading of Read More

The pressing global challenge of climate change necessitates a concerted effort to limit greenhouse gas emissions particularly carbon dioxide. A critical pathway is to replace fossil fuel sources by electrification including transportation. While electrification of light-duty vehicles is rapidly expanding the heavy-duty vehicle sector is subject to challenges notably the logistical drawbacks of the size and weight of high-capacity batteries required for range as Read More

This work discusses the current scenario and future growth of electrochemical energy devices such as water electrolyzers and fuel cells. It is based on the pivotal role that hydrogen can play as an energy carrier to replace fossil fuels. Moreover it is envisaged that the scaled-up and broader deployment of the technologies can hold the potential to address the challenges associated with intermittent renewable energy generation. From a sustainability per Read More

Hydrogen is a promising solution for the decarbonisation of several hard-to-abate end uses which are mainly in the industrial and transport sectors. The development of an extensive hydrogen delivery infrastructure is essential to effectively activate and deploy a hydrogen economy connecting production storage and demand. This work adopts a mixed-integer linear programming model to study the cost-optimal design of a future hydrogen infrastru Read More

Experiments and numerical simulations were conducted to study the flame acceleration (FA) in stoichiometric CH4/H2/air mixtures with various hydrogen blend ratios (i.e. Hbr = 0% 20% 50% 80% and 100%). In the experiments high-speed photography was used to record the FA process. In the calculations the two-dimensional fully-compressible reactive Navier-Stokes equations were solved using a high-order algorithm on a dynamically adapting mesh. T Read More
