cenex (centre of excellence for low carbon & fuel cell technologies)

Loughborough

Cenex was established as the UK’s first Centre of Excellence for Low Carbon and Fuel Cell technologies in 2005. Today, Cenex focuses on low emission transport & associated energy infrastructure and operates as an independent, not-for-profit research technology organisation (RTO) and consultancy, specialising in project delivery, innovation support and market development. We also organise Cenex-EXPO, the UK’s premier low carbon vehicle event, to showcase the latest technology and innovation in the industry. Our independence ensures impartial, trustworthy advice, and, as a not-for-profit, we are driven by the outcomes that are right for you, your industry and your environment, not by the work which pays the most or favours one technology. Finally, as trusted advisors with expert knowledge, we are the go-to source of guidance and support for public and private sector organisations along their transition to a zero-carbon future and will always provide you with the insights and solutions that reduce pollution, increase efficiency and lower costs. Together, we can lower your emissions through innovation in transport and energy infrastructure. View our projects and case studies [https://www.cenex.co.uk/projects-case-studies/] to see more of the work we do. INDEPENDENT: Truly impartial advice you can trust, based on in-house findings rather than manufacturer calculations. NOT-FOR-PROFIT: Driven to reduce the environmental impact of transport, energy and infrastructure, not by profits or returns-on-investment. EXPERTS: Access the best possible low emission solutions supported by evidence-based research, consultancy and models.

High Wycombe

BM TRADA has a long history and heritage that we are justifiably proud of and we can trace our origins back over 80 years to 1934. We are a global testing, inspection and certification company that delivers critical services in materials testing, product qualification testing, inspection and certification to the Fire and Building Products marketplace, where failure in service is simply not an option. Everything BM TRADA does is designed to help our customers to develop better products and processes; get their products to market on time; save time and money; and minimize the risk associated with product and process development as well as product production. Our purpose as a business is a simple one. To help our customers to make certain that all of the materials, products and processes we test, inspect and certify for them, regardless of the industry sectors they operate in, are always safe in their end application; are of marketable quality; are compliant with all relevant standards and industry regulations; and are ultimately fit for purpose. In 1934, a forerunner of what later became the Timber Research and Development Association (TRADA) was set up, its mission, to promote the use of wood in construction in the face of a growth in the use of alternative materials. 60 years later in the mid 1990s and following a management buyout of TRADA’s operating companies, the testing, inspection and certification services were grouped together under the three brands, BM TRADA Certification, Chiltern International Fire and TRADA Technology.

Water is our life elixir and at the same time a limited resource. BWT advocates the sustainable and responsible use of the precious resources of our blue planet. Water is our mission. It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect). In 1811 the Italian physician Amedeo Avogadro finally found the H2O formula for water. Although water has a simple molecular structure, it nevertheless has unique physical properties. It is the only element that exists on our planet in a solid, liquid and gaseous aggregate state. It is these special properties that make water so fascinating and so important for all creatures. Water has 775 times the density of air. This fact causes the ‘buoyancy’ effect, which enables us - and most mammals - to swim. Many substances expand when they are subjected to heat and reduce their density at the same time; conversely, they increase their density when cooled down. When a liquid is cooled, the colder part sinks to the bottom. The freezing process of water is the other way round. Water reaches its maximum density at 4 degrees Celsius, which is exactly 0.999973 kg/l. Ice weighs 0.91 kg/l – which is the reason why icebergs float. This also explains why frozen water bottles explode and why fish can survive in a frozen lake. They live at the bottom where the water is the heaviest, as the temperature there is approximately 4 degrees Celsius. Water is a very bad heat conductor. This property is of utmost importance for the global climate. Water can actually store a lot of heat, which it then releases again during the cold season. In the warm season, however, it prevents excessive heating. In this way water moderates the differences in temperature. If one cubic centimetre of water evaporates (at approx. 100 degrees Celsius), its volume expands to 1243 cubic centimetres (vapour pressure) - a process that formed the basis of the construction of the steam engine; this machine eventually gave rise to the Industrial Revolution. The physical and chemical properties of water make it a universal solvent and means of transport, which is integrated into all cycles of nature, both micro- and macroscopic. Without water, for example, there would be no circulation of nitrogen or phosphorous - both essential elements in the biosphere - as there is no way for the corresponding ions to be transported. Water can dissolve salts and feed these in dissolved form to plants. Plants then use these ions as nutrients and release the water they don’t need for their nitrogen metabolism into the atmosphere. This small water cycle is as important as the large one - without it, and therefore without water, there would be no life.
