Rolls - Royce offers with its MTU microgrids the company ’s first eco - well-disposed and on - situation power multiplication answer desirable for agricultural applications . These self-directed superpower grids combine renewable energy sources with battery memory board and gas and diesel motor generators using a microgrid dominance scheme developed by Rolls - Royce , thereby reduce CO2 discharge in power propagation . Farmers also lose their dependency on the public gridiron and can mix existing energy sources such as photovoltaics or biogas plants , which offers fiscal welfare . Rolls - Royce will be presenting its microgrid solutions for farming diligence at the agrarian trade show Agritechnica from 10 to 16 November .
“ Many farmers already have large - shell photovoltaic or biogas works and are therefore ideally outfit to use a microgrid . Our MTU EnergyPack , the barrage container , and a overbold energy management system allow the various energy sources to be optimally deployed – both technically and in term of cost , ” explains Cordelia Thielitz , Vice President Microgrids at Rolls - Royce .
The components of a Microgrid can be adapted fit in to the requirements . The possible applications in agriculture are manifold and offer vantage in terms of restitution - on - investing ( ROI ) , decentralization and decarbonisation . Here are three examples :
quality power from biomassInstead of continually pump all the electric magnate gain ground from a biogas industrial plant into the public gridiron , it can be stash away in the MTU - EnergyPack . The smart muscularity management scheme then ensures that this get-up-and-go is only fed into the public grid at time of apex need , when prices are at their highest .
ego - sufficient greenhousesTo fanfare and grow , crops cultivated in greenhouses need temperature levels and light photo to be stay fresh as constant as possible . The heat and powerfulness need to achieve that constitute major cost factors for any farmer .
But with combined index generation using a photovoltaic installation and MTU source connect up to a battery and master controller , the greenhouse can operate independently round - the - clock without refuge to the public grid . Electrical Department of Energy generated by photovoltaics and a gas - power CHP faculty during the daytime can be fed into the batteries , where it is subsequently available for illuminate the crop and other electric consumer . Heat from the CHP module is used to heat the greenhouses while CO2 recoup from its exhaust emissions promotes plant increase .
Profitability in times of changeFor farmers in Germany who generate power for the public control grid using photovoltaics and biogas plants and are subsidized under the German Renewable Energies Act ( EEG ) , the microgrid can be a very worthwhile investment . This is because subsidy rate are falling , with many subsidy dodge soon to reach the oddment of their twenty - twelvemonth term . Furthermore , operators of large - weighing machine PV works also have to bear an EEG levy en masse on the power they run through themselves .
Integrating these systems with batteries and a smart controller creates new monetary value benefit for farmers , who trim back their CO2 production at the same time .
“ Integrating existing renewable energy sources as a microgrid make an independent , reliable supply of energy which is aristocratic on the surroundings and save money . For a not inconsiderable number of farmers , microgrids can open up up novel take in potential , ” say Armin Fürderer , head of client solutions in the power multiplication section at Rolls - Royce .
