Rolls Royce acquires technology for the electrically­assisted charging of MTU engines


New €2.3m project to maximise offshore wind power production


of the control strategies. The selected wind farm will


have extensive measurement equipment installed as part of the validation process for the simulations. James Sinfield, WFCT


A new £20.2 million project aimed at maximis- ing energy production from offshore wind whilst reducing turbine loads has been launched. The Carbon Trust’s Offshore Wind Accelerator’s Wind Farm Control Trials (WFCT) will investigate the impact of focusing on strategies to improve energy generation across an entire wind farm, rather than individual turbines. Optimising control strategies to reduce wake


effects is said to lower the levelised cost of energy (LCoE) by increasing the total wind energy yield and reducing fatigue, saving operational and maintenance costs. They are also expected to increase availability and extend the lifetime of existing and future assets. The first stage of the


project involves analysis to determine the most suitable wind farm test site for the trials and an optimisation of


Project Manager at the Carbon Trust said: “The project has the potential to have a significant impact on cost reduction with a win- win on improving annual energy production and at the same time reducing opera- tional and maintenance costs.” The trials are expected to be undertaken in 2018 and full results are expected in 2019. The UK is one of the best locations for wind power in the world, and is considered to be the best in Europe. Wind power contributed


11% of UK electricity generation in 2015, and 17% in December 2015. Allowing for the costs of pollution, particularly the carbon emis- sions of other forms of pro- duction, onshore wind power is said to be the cheapest form of energy in the UK.


Rolls-Royce has acquired from G+L innotec the exclusive rights of use for a new technology for the electrically-assisted charging of off-highway combus- tion engines in the power range above 450 kW. The new invention from the development and engineering services is protected by patents and has thus not been available on the market to date, reports UKPN. Rolls-Royce plans to offer engines of its MTU brand with


this key technology - designed for the electrically-assisted charging of off-highway combustion engines in the power range above 450 kWas - as of 2021. “Electrically-assisted charging is a milestone on the way


to the hybridising of the engine. Using this technology, it will be possible for us to develop agile, low-consumption engines,” said Dr. John Kech, Director of Development Turbocharging & Fluid Systems at MTU. MTU and G+L innotec will complete the next stages of development on the basis of a close partnership. On the basis of a development collaboration agreement


with G+L innotec, MTU has equipped its turbochargers with this electric drive and has carried out component tests to determine its possible potential. In the next stage, the two partner companies will


prepare the new products for series production. This mean that, as of 2021, MTU will be able to launch engines equipped with this technology on the market. The first area of application suitable for these engines include ships and emergency backup gensets. The electrically-assisted charging system comprises an electric drive combined with a traditional turbocharger developed and manufactured by MTU. As a result, the turbocharger can be accelerated electrically and the charge pressure built up earlier. In operating conditions, in which the energy required for


a faster charge pressure of the turbine would normally not be sufficient, it is also possible to build up with the aid of the electric drive. Using the technology developed by G+L innotec, MTU


will be able to increase the acceleration capability of marine engines, for example, and also the load response capabilities of generator drives significantly. In addition it will also be possible to reduce the engine’s fuel consump- tion and emissions in a variety of different applications. Due to the increased load response capability, emergency standby gensets will be able to deliver their full output even faster than was previously the case. According to the manufacturer, ‘this technology is ideally suited to diesel and gas engines’.

Schneider Electric UK confirms green goals for 2030 ­ using 100% renewable electricity and doubling its energy productivity


joined two global initiatives to achieve these goals – the RE100 movement to use only clean power and the EP100 scheme to get twice the economic output from every unit of energy consumed. These commitments will cover more than 1,000 electricity consuming sites around the globe, including 200 factories. Schneider Electric plans to leverage a wide range of renewable energy sources, including solar, wind, geothermal and biomass, reports the company. These will include onsite generation, such as its existing solar rooftops at its sites in India and Thailand, as well as geothermal equipment at its offices in the UK. Using these technologies it hopes to achieve an preliminary target of 80% renewable electricity use by 2020. The company will also invest in the long-term procurement of offsite renewables through


S


Power Purchase Agreements (PPAs), Energy Attribute Certificates (EACs) and green tariffs. Emmanuel Lagarrigue, Chief Strategy Officer and Executive Vice President at Schneider Electric said: “The commitments we have made today in joining RE100 and EP100 to source 100% renewable electricity and reflect on the doubling of our energy productivity are a demonstration of how consumers and business can be empowered to ensure the affordability, resilience, sustainability and security of the energy that they consume.”
