Applications & Pathways

This study aims to present a philosophical and quantitative perspective of a propulsion system for a large-scale hydrogen-fuelled liquid-hydrogen (LH2) tanker ship. Established methods are used to evaluate the design and performance of an LH2-carrier propulsion system for JAMILA a ship designed with four cylindrical LH2 tanks bearing a total capacity of ~280000 m3 along with cargo and using the boil-off as propulsion and power fuel. Additionally the Read More

Fuel cell based micro-combined heat and power (CHP) units used for domestic applications can provide significant cost and environmental benefits for end users and contribute to the UK’s 2050 emissions target by reducing primary energy consumption in dwellings. Lately there has been increased interest in the development of systematic methods for the design of such systems and their smoother integration with domestic building services. Several model Read More

The Energy Systems Catapult (ESC) explored the role of households in a net-zero emissions society to accompany the CCC’s Net Zero report looking at opportunities and challenges for households to reduce emissions from today’s levels and to support the stretch from an 80% emissions reduction to a net-zero greenhouse gas target. As well as describing a net-zero emissions world for households of different types the ESC looked at average househo Read More

Energy–structure–function (ESF) maps can aid the targeted discovery of porous molecular crystals by predicting the stable crystalline arrangements along with their functions of interest. Here we compute ESF maps for a series of rigid molecules that comprise either a triptycene or a spiro-biphenyl core functionalized with six different hydrogen-bonding moieties. We show that the positioning of the hydrogen-bonding sites as well as their number ha Read More

A potentially viable solution to the problem of greenhouse gas emissions by vehicles in the transportation sector is the deployment of hydrogen as alternative fuel. A limitation to the diffusion of the hydrogen‐fuelled vehicles option is the intricate refuelling stations that vehicles will require. This study examines the practical use of hydrogen fuel within the internal combustion engine (ICE)‐powered long‐haul heavy‐duty trucking vehicles. Specifically it appraises Read More

The cost reduction of hydrogen refueling stations (HRSs) is very important for the popularization of hydrogen vehicles. This paper proposes an optimized operation algorithm based on hydrogen energy demand estimation for on-site hydrogen refueling stations. Firstly the user’s hydrogen demand was estimated based on the simulation of their hydrogenation behavior. Secondly mixed integer linear programming method was used to optimize the operation Read More

Tailpipe emissions from vehicles consist of CO2 and other greenhouse gases which con‐ tribute immensely to the rise in global temperatures. Green hydrogen produced from the gasification of biomass can reduce the amount of CO2 emissions to zero. This study aims to provide a modelling framework to optimize the production of hydrogen from biomass waste obtained from different cities for use in the road transport sector in Nigeria. A gasification model Read More

With the rapid development of hydrogen production by water electrolysis the coupling between the electricity-hydrogen system has become closer providing an effective way to consume surplus new energy generation. As a form of centralized management of distributed energy resources virtual power plants can aggregate the integrated energy production and consumption segments in a certain region and participate in electricity market transactions as a Read More

We report the development of new tools and methods for facile integration and meaningful representation of high throughput data generated by genome-wide analyses of the model cyanobacterium Synechocystis PCC6803 for future genetic engineering aiming at increasing its level of hydrogen photoproduction. These robust tools comprise new oligonucleotide DNA microarrays to monitor the transcriptomic responses of all 3725 genes of Read More

This study investigated a pre-cooled turbojet engine for a Mach 5 class hypersonic transport aircraft. The engine was demonstrated under takeoff and Mach 2 flight conditions and a Mach 5 propulsion wind tunnel test is planned. The engine is composed of a pre-cooler a core engine and an afterburner. The engine was tested under simulated Mach 4 conditions using an air supply facility. High-temperature air under high pressure was supplied to the engine co Read More
