Energy System 2050
Our interdisciplinary team of scientists performs energy-related process and systems analyses for the purposes of planning and consultation. Data searches and system simulations are used to determine energy and mass balances, as well as performance data, emissions and the costs of energy systems. Such quantifiable values are then used as the basis for comparatively assessing energy systems. Current priorities include the development of energy strategies in order to meet the German Federal Government’s greenhouse gas reduction targets, designing infrastructures for a sustainable and secure energy supply (e.g., via power-to-gas, power-to-fuel, biomass-to-liquid) and the conducting of cost analyses for the implementation and operation of new technologies for future energy markets.

Thermal Energy Storage systems for seasonal variations in heat demand - Dr Daniel Friedrich
The Institute for Energy Systems Seminar Series presents Dr Daniel Friedrich. This IES Seminar took place on the 25th of September 2015 in the School of Engineering at the University of Edinburgh. Presentation Abstract: Balancing the seasonal variation in demand is one of the largest challenges in the decarbonisation of the energy system. For example, in the UK the natural gas demand increases from around 1.5 TWh per day in summer to more than 3.0 TWh per day in winter. This variation is to a large extent due to the increased heating demand and here specifically due to the domestic heating demand. Currently the demand fluctuations can be balanced due to the dispatchable nature of fossil fuel based electricity and heat generation. However, with the increase of non-dispatchable renewables in the energy mix, different solutions are needed. One solution to balance the seasonal variation is seasonal energy storage. However, the required storage capacity for the UK would be more than 100 TWh. Several options ranging from thermal aquifer storage to power-to-fuel systems with liquid fuel storage have been proposed. Here an overview of the different approaches, including the opportunities and challenges, is presented. While most of these methods have been successfully deployed, they are rather expensive and/or suffer from low efficiencies. A second option is a tighter integration of the electricity and heating systems and the utilisation of seasonal variations in renewable energy generation with short to medium term storage. Speakers Bio: Daniel Friedrich received a Diplom in Technomathematik from Universität Karlsruhe (TH), Germany, in 2005. In the same year, he joined the Optoelectronics Research Centre at the University of Southampton, where he obtained his PhD in 2010. In 2009 he joined the School of Engineering, at the University of Edinburgh, to continue his research activity as a post-doctoral researcher and, in March 2013, he was appointed as a Chancellor’s Fellow in Mathematics for Engineering Applications. Daniel has been working extensively on the mathematical modelling and optimisation of engineering systems with particular focus on microfluidic systems, adsorption based gas separation and thermal energy systems. His current research interests are in the efficient numerical simulation and optimisation for low carbon technologies, in particular Carbon Capture and Storage and Thermal Energy Storage.

A new way to store Thermal Energy
In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel -- such as wood,brush or dung -- that is collected with significant time and effort. Now, a new chemical composite developed by researchers at MIT could provide an alternative. It could be used to store heat from the sun or any other source during the day in a kind of thermal battery, and it could release the heat when needed, for example for cooking or heating after dark. A common approach to thermal storage is to use what is known as a phase change material (PCM), where input heat melts the material and its phase change -- from solid to liquid -- stores energy. When the PCM is cooled back down below its melting point, it turns back into a solid, at which point the stored energy is released as heat. There are many examples of these materials, including waxes or fatty acids used for low-temperature applications, and molten salts used at high temperatures. But all current PCMs require a great deal of insulation, and they pass through that phase change temperature uncontrollably, losing their stored heat relatively rapidly. Instead, the new system uses molecular switches that change shape in response to light; when integrated into the PCM, the phase-change temperature of the hybrid material can be adjusted with light, allowing the thermal energy of the phase change to be maintained even well below the melting point of the original material.

The solar sector nearly doubled the amount of solar power installed last year compared to 2015, GTM Research and the Solar Energy Industries Association said in their annual analysis of the US solar sector. Indeed, more solar power was added last year to the nation's electricity grid than any other source of energy - a milestone for the burgeoning industry." Liquid storage of solar energy - more effective than ever before https://phys.org/news/2017-03-liquid-storage-solar-energy-effective.html "Many consider the sun the energy source of the future. But one challenge is that it is difficult to store solar energy and deliver the energy 'on demand". A research team from Chalmers University of Technology in Gothenburg, Sweden, has shown that it is possible to convert the solar energy directly into energy stored in the bonds of a chemical fluid - a so-called molecular solar thermal system. The liquid chemical makes it possible to store and transport the stored solar energy and release it on demand, with full recovery of the storage medium." Make perovskite solar cells stable https://www.nature.com/news/make-perovskite-solar-cells-stable-1.21807 "The hunt is on to find a cheap and safe solar-cell technology. Crystalline silicon is the basis for 90% of commercial photovoltaic devices, which use semiconductors to convert light into electricity. But silicon photovoltaics are still expensive to process, their manufacture produces toxic by-products and they are cumbersome to install. Perovskites could be a game-changer." ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

Daytona State College Thermal Energy Tank
www.DaytonaState.edu On Nov. 20, Daytona State College celebrated completion of a new 2.5-million-gallon thermal energy storage tank constructed on the main campus, with a ribbon-cutting that marks what is expected to be years of energy savings for the institution. Representatives from Florida Power & Light Company (FPL) joined college officials and members of the District Board of Trustees for the event on the Wetherell Center’s fourth-floor outdoor terrace, with the 80-foot-tall storage tank as a backdrop to the west. “This is a great example of partnering to a good end. Florida Power & Light shared the opportunity with us, including rebates of over $1 million,” said college COO/Provost Tom LoBasso, pointing to energy-efficiency rebates DSC received from FPL upon completion of the $3 million project. Board of Trustees Chair Lloyd Freckleton noted that the thermal energy storage tank is a functional, economical, environmentally-sound enhancement for the college. “It showcases the college’s smart choices – from fiscal savings to useful partnerships,” he said. “We welcome further wise investments in our infrastructure, as well as partnering for academic and workforce training programs.” John Haney, FPL’s director of customer service, noted that such partnerships help keep rates low for all FPL customers. “I commend the board for making such a forward thinking and energy efficient solution for the college,” he said. The tank allows Daytona State to take advantage of special low-demand (off-peak) rates offered by FPL. This is achieved by chilling water for the college’s cooling systems at night and storing it in the insulated storage tank, with 10-inch walls of reinforced concrete, at 42 degrees for use during times of peak demand, a process known as load shifting. The tank is projected to provide the college with more than $200,000 annually in energy savings. Construction was completed in August by CROM Corp. of Gainesville, Fla.
