Helm Wind: Final Feasibility Study - One Page Summary

Offshore Wind has huge potential to reduce carbon emissions and create economic prosperity, as well as increasing energy security of supply. For this potential to be unlocked, significant challenges that need to be overcome:Electricity costs need to be competitive with current (2010) onshore wind costs by 2020 and with conventional generation by 2050,Increased yields: annual offshore farm availability to be increased to 97%-98% or better,Reduce technical uncertainties to allow farms to be financed in a...

ETI Insights Report - Domestic Energy Services

J. Batterbee
Our homes are becoming smarter and ever more connected, through technology from a wide range of innovative vendors.The new level of data and control created by technology is likely to lead to a profound change in energy retail. Over time, the possibility of retailing service experiences people value is likely to open up in place of being limited to the retail of units of energy which people simply don’t understand. While this may well happen...

2050 Energy Infrastructure Outlook: Multi Vector Integration Analysis - Multi Vector Interaction Cases Shortlist

I. Walker, A. Stewart, T. Staw & E. Tiniou
The project aims to improve the understanding of the opportunity for and implications of moving to more integrated multi vector energy networks in the future. Future energy systems could use infrastructure very differently to how they are employed today. Several individual energy vectors - electricity, gas and hydrogen - are capable of delivering multiple services and there are other services that can be met or delivered by more than one vector or network.

Distinguishing between the Frenkel and Widom lines in supercritical Nitrogen

, , &
In recent years narrow transitions between gaslike and liquidlike behaviour of fluids at temperatures significantly exceeding the critical temperature Tc (above 6Tc) and densities over double the critical density were observed. Some explained this by extrapolating Widom lines (thermodynamic continuation of vapour pressure curve) from the critical point (CP) and others with newly proposed Frenkel line. The Frenkel line is unrelated to the CP, Widom lines and vapour pressure curve. It should follow P,T path...

Investigating the effect of pH and functionalisation upon the self-assembly of NDIs

, &
Stimuli responsive naphthalene diimides (NDIs) have promising potential in devices such as smart windows. NDIs can be easily and reversibly reduced to a highly coloured radical anion or dianion from a transparent or transmissive state. We believe that these systems are particularly sensitive to small changes, for example differing the functionality of the NDI or altering pH. We hypothesise that there is a related change in aggregation and self-assembly of the molecules when these factors...

Clarifying the origins of the low-temperature dielectric anomaly in BaZrO3

&
The proposed experiments will help to elucidate the origins of the dielectric anomaly in the cubic perovskite BaZrO3. This material finds use in proton-conducting fuel cells and microwave dielectrics. Recent studies demonstrated that the dielectric losses in BaZrO3 can be reduced dramatically by doping it with Nb and Ga, thus making the resulting material attractive for use in dielectric resonators for wireless communications. The observed drop in the losses has been correlated with the disappearance...

Local structure in the hidden order phase of URu2Si2

, , &
URu2Si2 is one of the most actively studied materials exhibiting unconventional behaviour due to electronic correlations. The mystery of this compound is the nature of the so-called `hidden order' state, which sets in below 17.5 K. This transition is characterised by an enormous change in entropy (~0.2R ln2). A small `parasitic' antiferromagnetic order sets in in the HO phase, but its ordered moment is far too small to explain the change in entropy. The nature...

Temperature responsive binary gelation of pNIPAM microgels and a neutral triblock-copolymer surfactant.

, &
SANS will be used to study the structure of an adsorbed polymermic surfactant on pNIPAM microgels. It has been observed that when mixtures of pNIPAM microgels and triblock-copolymer surfactant are heated above the volume phase transition temperature of pNIPAM, the sample transitions from a liquid to a gel. This transition is fully reversible. We have demonstrated that the gelation is a result of the association of the polymers at elevated temperatures, however the nature of...

Investigating local charge- and vacancy-ordering in a sodium-ion cathode

, , , , &
Sodium-ion batteries (NIBs) are a cheaper alternative to lithium-ion batteries. At present, the capacity of NIBs is too low for practical applications and limited by the cathode; to increase this capacity, a detailed understanding of the charge compensation mechanism is required. We have been investigating a new cathode material, Na0.67[Mg0.28Mn0.72]O2, with a promisingly high capacity. Bulk structural invesitgations - using laboratory X-ray diffraction - reveal honeycomb ordering across the Mn/Mg sublattice. However, fits to the...

Effects of Chiral Components on the Structure of Deep Eutectic Solvents

, , , , , , &
Deep eutectic solvents (DES) are novel liquids composed of inexpensive components, and are non-flammable, with a low volatility. One problem with DES is frequently their relatively high viscosity so selecting components which make a tractable liquid with low enough melting point and viscosity to be useful in applications is challenging. Here we wish to probe the structure of DES which have similar components but very different viscosities & melting points, based on tartaric acid (TA)...

Negative Thermal Expansion in the (Bi0.5Na0.5)1-x(Ba0.4Sr0.6)xTiO3 System

, , , &
The (Bi0.5Na0.5)1-x(Ba0.4Sr0.6)xTiO3 (BNT-BST) is being investigated as a lead-free ferroelectric system for energy storage capacitors. At x = 0.2 BNT-BST exhibits a tetragonally distorted perovskite structure. Dielectric measurements reveal two anomalies at ca. 125 C (ferroelectric to relaxor-ferroelectric) and 360 C (relaxor-ferroelectric to paraelectric). The former is associated with a change in structure from tetragonal to cubic symmetry, which involves a 25 C range of negative thermal expansion (NTE), where a dynamic deformation of the...

Muon spin spectroscopy to probe depth-dependent carrier lifetimes in silicon photovoltaics

, , , , , &
Crystalline silicon is used for >90% of photovoltaic solar cells. Electron-hole pairs are produced when light of certain frequencies is absorbed. Some of these charge carriers are lost due to recombination processes in the silicon before they are collected, and the lifetime (or diffusion length) of the carriers defines the quality of a silicon wafer. A new ISIS-developed muon spin spectroscopy technique has advantages over incumbent methods as it is possible to: (i) implant the...
