NEWS EDITOR’S CHOICE - PHOTON ENERGY INSTALL 384KWP OF SUNPOWER AT CAMBRIDGE T


he first phase build of a new development at the University


of Cambridge has now been completed and features 384kWp of solar Photovoltaic (PV). It was installed by Photon Energy and is mounted on nine apartment blocks. The North West Cambridge


development is being built in a number of phases and will provide up to 3,000 new homes and community facilities to help overcome problems with overcrowding and rising land prices in the city. Photon Energy won the tender from main contractor Wates to install 384.23kWp of solar PV at Lot 2 of


the development, comprised of key worker units, local shops and a café, positioned around a market square. This development has been


carefully created with sustainability in mind. The apartments have been built to the Code for Sustainable Homes Level 5 and contain a number of features including triple layers of insulation, brown roofs and a district heating system, as well as the solar PV arrays generating clean energy for each home. The solar PV arrays had to be


designed by Photon to fit in with various elements on the roofs of


the apartment buildings. These included the ‘brown roof’ areas covered with soil and sections that were laid with pebbles, to ease flooding and improve insulation. Due to the limitations with roof


space, SunPower 327 PV modules were chosen to ensure maximum output, with a total of 1,175 being installed. The modules were fixed to a K2 Systems D-Dome mounting system. The solar PV will generate


approximately 262,355kWh of electricity each year for the local residents and save 136 tonnes of CO₂ emissions.

STORAGE SYSTEMS DEVELOPMENT


CMBlu Projekt AG and Schaeffler Technologies AG & Co. KG have signed a joint development agreement to develop large


- scale energy storage systems. Over


the past five years, CMBlu – in collaboration with research groups from German universities – has developed the novel and renewable Organic Flow Storage Technology for power grids up to prototype scale. The goal of both partners is to make a substantial contribution to a secure, efficient and sustainable power supply worldwide. Organic Flow Batteries can be used


SOLAR POWER FOR COMMERCIAL USE COMES OF AGE


Whilst many in the renewable energy sector greeted the closure of the Government’s Feed-In Tariff scheme with dismay, solar power company Mypower (which installed a solar PV system on the roof of Gloucester Cathedral) believes solar power for businesses and agriculture is now ready to stand on its own two feet and compete with 'mainstream' energy in the open market. Commercial scale solar power can now compete on the free market as it offers electricity at around 70%


cheaper than grid supplied electricity, adds certainty to energy prices for 25 years, and reduces carbon dioxide emissions with the beneficial PR this brings. Solar power fixes the price of a significant proportion of a company's electricity at less than 5p/unit compared to the current price from the National Grid of approx 14.5p/unit. Mypower believes removing the FITs will create a stable and market driven demand for solar power as it


removes reliance on Governmental policy. Plus some companies perceived the FIT system as too complex so wouldn't consider it and others wouldn't take subsidies as a matter of principle. Ben Harrison, Managing Partner of Mypower, says: "Over the last two years, we've seen electricity


prices for SMEs increase by more than 35% effectively removing £35,000 off the bottom line from a company spending £100,000 on energy. The significant reduction in the cost of solar PR system installation, the low cost of generating solar electricity and the reduction in overall energy bills because of this means solar power no longer needs subsidies." During the past 12 months, many of Mypower customers have opted to sell their surplus energy directly


to suppliers as market value of 5.8-5.9p/unit is greater than the price of 5.24p/unit guaranteed by the export Feed-In Tariff. Mypower, therefore, doesn't see the closure of the FIT scheme as barrier for commercial or agricultural customers. www.mypoweruk.com


flexibly as stationary energy storage units in the power grid and contribute to the balance between generation and consumption. The technology can be used in the intermediate storage of renewable energies or peak shaving in industrial plants. Another field of application is the charging infrastructure for electromobility. As buffer storage, the batteries contribute to the relief of medium


- voltage grids, eliminating the


need for upgrading due to additional loads. Ultimately, a decentralised charging infrastructure for electric vehicles will only be possible with powerful and scaleable energy storage systems, such as Organic Flow Batteries. The underlying technology is similar


to the principle of conventional redox flow batteries. The electrical energy is stored in chemical compounds, which form electrolytes in water solution. In contrast to conventional, metal


- based


systems, organic molecules derived from lignin are used for storage. Lignin can be found in every plant such as trees or grass. It is a naturally renewable source and is extracted in pulp and paper production as a waste product on a million


- tonne scale. www.schaeffler.com

range of fully automatic burners. These burners independently and automatically set up plant parameters such as temperature, pressure and boiler power, as well as reacting to ambient variables including altitude and climate. The system recognises and adapts to all types of boilers and processes for optimum performance. These characteristics help simplify installation and can reduce commissioning time, compared with conventional burners. For the rare occasions when operator intervention is required, these units have a user-friendly LCD controller. During operation, these burners have a proactive

and self-regulating mass flow sensing capability, automatically adjusting fuel and air flow. The


ignition point is burner determined and regulated to ensure optimum ignition. The products intelligent technology facilitates


remote operation and data monitoring via PC, laptop, tablet and IPhone. Plant performance is constantly monitored and real time alerts are issued promptly, highlighting performance or maintenance issues. Operational statistics are measured against key performance indicators, providing an up-to-the-minute overview of plant functions and efficiency. These smart features also provide the resources for preventative maintenance regimes and remote system diagnostics, simplifying and reducing service management costs. www.gpburners.co.uk
