CASTEP is a parameter-free and predictive quantum mechanical atomistic simulation code developed by Professor Payne in the Department of Physics at the University of Cambridge. CASTEP has been sold commercially by Accelrys since 1995, with more than 800 industrial customers using the package. As part of Accelrys' Materials Studio, it can be used by non-experts to determine a wide range of physical and chemical properties of materials. Companies can thus perform `virtual experiments' using CASTEP. As quantum mechanical simulations can be cheaper and more flexible than experiments, CASTEP invariably reduces costs and accelerates product development.
The impact presented is the use of research carried out in the School of Chemical Engineering by a range of multinational food industries (inc. Unilever, Cargill, PepsiCo) to engineer a series of fat-reduced foods such as low fat spreads (LFS), dressings, margarine, sauces and mayonnaise. This has allowed them to build up a portfolio of novel low fat products; this portfolio would be much reduced or in some cases non-existent without the research contribution and capability generated by the Birmingham group as stated by Peter Lillford5.1 (former Chief Scientist, Unilever) and John Casey, (Vice President Biological Sciences, Unilever)5.2. These products are a significant and growing market segment e.g. LFS now outsell margarine/butter in a number of countries and are estimated to be worth globally 10 Billion Euros per year between 2008-13. Thus these products are having a significant impact on the industries' profitability. In addition, consumption of low fat foods act to tackle obesity with knock on effects for government (health service, lost GDP etc.) and the community as a whole.
The work described here has impacted on European policy and standards concerning energy efficiency in Building Services.
The impact arises from two Welsh School of Architecture led and European Commission funded projects, HARMONAC (focussed on inspection of air-conditioning systems) and iSERV (focussed on automatic system monitoring and feedback). These pan-European projects demonstrate achieved energy savings of up to 33% of total building electricity use in individual buildings, and potential savings up to €60Bn. These projects demonstrably impacted the recast European Energy Performance of Buildings Directive (EPBD) and the revision of EU Standards (European Committee for Standardisation (CEN)).
Dr David Toke's research at the University of Birmingham has contributed to policy made by governments in the UK and EU, and the work and policy of environmentally concerned NGOs. Renewable Energy is a crucial aspect of EU and UK sustainable energy strategies and feed-in tariffs have now become the preferred method of incentivising renewable energy in the UK. Toke made a major contribution to generating this change through his proactive dissemination of research on feed-in tariffs and the publication of a key public policy report, at a time when little was known about this type of policy instrument.
His research has stimulated debate among industry professionals and events organised by him have provided a forum where the industry and NGOs can develop an evidence-based dialogue. Through using popular media to disseminate his research findings, Toke has provided a source for greater public understanding of the related issues, and in particular has challenged the decisions of government. In a broader sense, his research has contributed to improving governmental and financial support for renewable energies in the UK and thus environmental sustainability.
This case study describes the national and international impact of research undertaken by Professor Chao, as part of an EU funded Framework 7 project, Digital Environment Home Energy Management Systems (DEHEMS). The project has improved existing household energy monitoring, tackling the issues of global warming and CO2 emission reduction in the domestic sector. The research has directly contributed to the development of a product called EnergyHive, subsequently marketed by Small to Medium-sized Enterprise (SME) Hildebrand Ltd, who was the industrial partner in the DEHEMS consortium. The research has delivered the following:
Beneficiaries of the research and the subsequent impact include: a commercial business, domestic energy consumers, UK and international energy companies and local authorities.
The SAFT-VR family of thermodynamic models has made it possible to predict reliably the behaviour of the many complex and challenging fluids that are found across a range of industrial sectors, including oil & gas, chemicals (refrigerants, surfactants, polymers), energy (carbon capture solvents, carbon dioxide-rich streams) and pharmaceuticals.
The SAFT-VR models have had a wide impact on industrial practice. At BP, they have been used to design novel surfactants that have increased the lifetime of oil fields up to five-fold, avoiding maintenance interventions costing millions of dollars and increasing productivity by 50% (worth $2-3 million per year per well). At Borealis, they have been used to understand how to increase the productivity of the reactor in the flagship Borstar process by 30%. At ICI and Ineos/Mexichem, they have been used to design efficient processes for producing replacement refrigerants with much reduced reliance on extreme and expensive experiments involving hydrogen fluoride, a highly corrosive substance. Industrial demand for access to the predictive capabilities of SAFT-VR has been such that Imperial College has licensed the software in 2013 to a UK SME in order to distribute it worldwide to users.
