  • Software for monitoring CO2 reservoirs

    Software for monitoring CO2 reservoirs

    Post-doctoral researcher and Pioneer Fellow Edoardo Pezzulli from the Swiss Federal Institute of Technology in Zurich(ETH) has developed software that makes it possible to continuously monitor carbon dioxide storage in reservoirs and reduce the risks involved. According to a press release, the mathematician is now endeavouring to bring his technology to market maturity. To this end, he founded the start-up Storra Dynamics GmbH with mechanical engineer Michael Liem.

    “Anyone who stores CO2 has a social responsibility,” Pezzulli is quoted as saying in the press release. “The plants must be safe for generations to come. With our monitoring system, we want to prove that the risks are limited and that operation at the highest level of safety is possible.” This is because there are geological uncertainties with this type of storage. First of all, it is necessary to analyse how much carbon dioxide can be injected into the site, and then the stored gas can be monitored to ensure that it remains bound. The newly developed software will then work like a digital twin by simulating pressure, temperature and load conditions in the storage site.

    Pezzuli is currently involved in the CITru pilot and demonstration project in the municipality of Trüllikon. Under the direction of ETH Zurich, the feasibility of injecting carbon dioxide through a disused borehole created by Nagra (National Co-operative for the Disposal of Radioactive Waste) is being tested. The scientist is responsible for the risk assessment and the development of the monitoring plan.

  • High-temperature solar power plants for continuous energy supply

    High-temperature solar power plants for continuous energy supply

    The centrepiece of 247Solar’s technology is a high-temperature heat exchanger developed by David Gordon Wilson, Professor Emeritus at MIT. By integrating this heat exchanger into a conventional turbine similar to a jet engine, efficient and emission-free energy generation becomes possible. The turbine utilises hot air, which is heated to around 1,000 degrees Celsius by solar energy, to produce both electricity and heat.

    Solar power plant with integrated energy storage
    An innovative component of this system is combined heat and power generation, supplemented by thermal energy storage. These store heat in solid materials, which can then drive the turbine when solar radiation is not available. This enables a continuous energy supply, regardless of the time of day and weather conditions. The generation capacity of the model presented is 400 kilowatts of electricity and 600 kilowatts of heat.

    The modular design of the system offers a wide range of possible applications, especially for remote or self-sufficient communities. This technology is ideal for combining with other renewable energy sources such as wind power to provide a holistic and sustainable energy supply.

    Bruce Anderson, Managing Director of 247Solar, emphasises that the main aim of developing this system was to overcome the intermittency issues of conventional renewables. The ability to provide uninterrupted energy represents a significant advance in the utilisation of renewable energy sources and could play a key role in the global energy future.

  • AEW Energie takes over 50 per cent of GA-Werkstatt.ch

    AEW Energie takes over 50 per cent of GA-Werkstatt.ch

    GA-Werkstatt.ch (GAW) is now owned equally by AEW Energie AG and the previous sole owner, Rotkreuz-based Herzog Kull Group Holding(HKG). With their new joint venture, the partners want to meet the increased demand in the field of building management for commercial properties. As stated in a joint press release, they aim to take a holistic approach and assume the project management role of a general energy company or total energy company.

    Both companies are convinced that a building will be an increasingly relevant element in the future energy system as a consumer, producer and store of energy. By working more closely together, they want to offer integrated energy solutions from a single source throughout the country.

    The competences of the new partners will complement each other: HKG will gain expertise in the planning of medium and high-voltage systems, according to the press release. The collaboration will enable a holistic view of buildings and grids in all areas of target grid planning. By acquiring a stake in GAW, AEW is expanding its portfolio of grid and energy-related services to include building technology, thereby strengthening its position as a provider of integrated energy services for its customers. Its associated company Virtual Global Trading AG is contributing its digitalisation expertise.
