Since 2007, Edinburgh researchers have played an important role in increasing the use of local, context-specific knowledge in the assessment of technological sustainability and efficiency in the bioenergy and solar sectors in East Africa and South Asia. This has taken the following forms:
Recognising a national shortage of young people adopting careers in physics, particularly in Wales, we used our experience in engaging the public with physics research to have an impact on the work of the young people's organisation Urdd Gobaith Cymru at its National Eisteddfod, one of the largest cultural youth festivals in Europe. At the heart of the pavilion, Aberystwyth researchers presented an exhibition of our research on the Sun and the Solar System, supported by the STFC Science in Society scheme. This core activity convinced the organisation to reintroduce a prominent science pavilion (the GwyddonLe), having originally planned not to host a science event. Since 2010, this has grown to be one of the largest and most popular events at the Eisteddfod, attracting external funding and allowing DMAP researchers to have a further impact on society by demonstrating physics to tens of thousands of school children and their parents.
Research by the University of Cambridge Department of Engineering (DoEng) on high-reliability micro-inverters for use in solar power systems was commercialised by DoEng spin-out company Enecsys Limited. Since 2008, Enecsys has attracted GBP34M in private investment, increased its number of employees from 7 to 75 people across three offices in Europe, North America and Asia-Pacific, and shipped more than 150,000 micro-inverter units. Its revenue in financial year 2012/13 was USD11.7M. Solar power installers have confirmed that Enecsys' products, in comparison with traditional string inverters, are: easier, cheaper and safer to install; more reliable; and able to extract more energy from an array of solar panels. Enecsys products are also changing the market for solar power with simple plug-in solutions that home owners buy from retailers and install themselves.
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.
The University of Southampton's pioneering research into energy harvesting has produced proven economic impacts together with impacts on public policy and international standards. Perpetuum, a spin-out from Southampton employing 10 people locally, has attracted £9.6 million in venture capital and developed the world's leading vibration energy harvester. Perpetuum's harvesters are enabling the deployment of zero maintenance, battery-free wireless systems in the rail industry where the technology has revolutionised bearing monitoring. This has enabled, for the first time, real-time monitoring of rolling stock, leading to cost savings, improved reliability, efficiency and safety. Their systems have been deployed on 200 trains across the UK (Southeastern) and Sweden (SJ AB). Southampton's research has driven wider industrial uptake of the technology and Perpetuum's is also the only energy harvester approved for use with the worlds leading suppliers of wireless condition monitoring equipment (GE Bentley Nevada, National Instruments and Emerson). Promotion of the technology has led to a £1.25 million TSB competition on energy harvesting and Southampton researchers are assisting in the development of international standards and increasing public awareness of the technology.
A 2008 `options appraisal' by the Mackintosh Environmental Architecture Research Unit (MEARU) for Cube Housing Association (CHA) impacted directly on practice apropos eliminating `fuel poverty' (energy cost >10% disposable income) and complying with the Scottish Housing Quality Standard (SHQS) — this achieved by a major combined heat and power (CHP) installation linked to thermal upgrading (complete 2012). This tangible impact for CHA in turn helps Scotland to achieve its CO2 reduction targets alongside improved public health. The initial research work by MEARU for CHA followed many years of work with energy efficiency and environmental quality in housing (2 below).
Developing renewable sources of energy has to go hand in hand with reducing energy demand through increased energy awareness and behavioural change. To this end a multidisciplinary consortium of researchers, led by Professor Christopher Howe (Biochemistry), have developed several biophotovoltaic (BPV) devices for off-grid electricity generation, and as educational tools. This has resulted in impact on commerce (i.e. the acquisition of a BPV spinout company by Ortus Energy Ltd in 2009 through share exchange), on society and culture (an award-winning `Moss Table' developed by the consortium, which incorporates BPV technology, has been exhibited internationally since 2011 and has received extensive international media coverage) and on educational practices (a prototype BPV educational tool for schools has been developed by Howe and colleagues in 2013 and trialled with 6th form students).
The impact is in the ERPE design of protocols which are subsequently used for evaluation and comparison of the performance of tidal energy converter designs. Researchers within the UK Centre for Marine Energy Research (UKCMER) at ERPE have led much of the fundamental and applied research that has supported the commercialisation of tidal energy technologies through the establishment of new international test standards and protocols.
ERPE researchers have regularly provided evidence which has influenced policy change in marine energy development in the UK and internationally with many ERPE graduating PhD's, subsequently employed in the marine energy sector.
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)).
As standard commercially-available imaging systems were unable to deliver the performance necessary for our astronomy research programmes, we formed a partnership with Andor Technology to develop two new specifically-tailored novel imaging systems: one to allow high-speed, high cadence imaging over an array of detectors whose capture times were precisely synchronised (for solar research); one to combine large format CCD detectors with a thermoelectric deep cooling design, removing the need for a separate, expensive cooling system (for exoplanet research). This partnership contributed to the development of new imaging products within Andor Technology (2008 — present), for which the company estimates a current total revenue value of over £1.7M per year. It has also helped Andor to maintain a leading position in the scientific camera market on a global scale, via the press and industry coverage obtained for the new technology development.
