  • Rubrik: Datum: Title: Solar Cell Efficiency – Approaching a Tipping Point to Widespread Adoption

    Compared to other renewable energy sources, solar has always enjoyed a relatively positive reputation. Solar panels do not present the visual intrusion of a wind turbine, nor the environmental impact of a nuclear power plant. The real obstacle to broader adoption lies in the science behind solar power itself – solar panel efficiency. Businesses, homeowners and developers are not likely to invest heavily in solar energy until solar panel efficiency reaches a tipping point – delivering performance that spurs large scale purchasing and lower manufacturing costs. With this goal in mind, several companies are actively seeking solutions on ways to improve solar panel efficiency – accelerating innovation and bringing the concept of ubiquitous solar energy closer to a reality.

  • Rubrik: Datum: Title: ISH Preview: Heat for the digital world

    ISH, the world's leading trade fair for building and heating technology, will take place from 14 to 18 March in Frankfurt, Germany. Sector coupling and the digitisation of heating technology will be at the top of the agenda this year.

  • Rubrik: Datum: Title: Battery Storage: Still Too Early?

    Renewable energy deployment over the last decades has posed unprecedented challenges for the planning and operation of power systems. In the context of increasingly decentralized and intermittent generation, power utilities and system operators need to rethink their portfolios, business models and positions in the market in order to be resilient to these changes and benefit from them.

  • Rubrik: Datum: Title: Solar Process Heat: Surprisingly popular

    Solar heat far from being a standard in production processes yet, but it is more widespread than you might think: System designers and collector manufacturers report more than 500 systems worldwide. The 2017 World Map of Solar Process Heat Specialists shows 71 companies in 22 countries.

  • Rubrik: Datum: Title: SuRe - The Global Infrastructure Standard for a Sustainable Future

    A multi-stakeholder process is under way to develop SuRe - The Standard for Sustainable and Resilient Infrastructure which consists of 65 key sustainability and resilience criteria divided into 14 themes covering environmental, governance and social (ESG) aspects.

  • Rubrik: Datum: Title: A versatile tool for remote measuring

    Hardly any other technology in the offshore industry is evolving as quickly as the LiDAR measuring method. The handy devices have finally also become affordable, and they are increasingly being installed at sea where their nearly unlimited capabilities can be fully used.

  • Rubrik: Datum: Title: Pushing down stagnation temperature

    The idea of having temperatures in excess of 200°C on their roof scares off a lot of potential solar-thermal customers. But the industry has now found ways to solve stagnation problems and limit high stagnation temperatures.

  • Rubrik: Datum: Title: Too little transparency in the storage market

    The company Solarwatt, from Dresden, Germany, developed its storage system “MyReserve” completely on its own and makes the battery modules itself. In an S&WE interview at the technology centre “Solarwatt Innovation”, the centre’s head Andreas Gutsch explained his take on battery technology and its future perspectives. Here we have put together his arguments, background information and forecasts.

  • Rubrik: Datum: Title: Solar power for a piglet farm

    A large number of farms depend on power supplied by diesel generators. An example from Spain now shows that these fossil fuel-powered systems can be almost completely replaced with PV systems.

  • Rubrik: Datum: Title: "He who has kept a good diary is fortunate"

    High operational availability of the wind turbines is a basic requirement for the economic operation of a wind farm - offshore even more so than onshore. Every day that a wind turbine at sea cannot operate is expensive. As part of Task 33 of the International Energy Agency, scientists and industry representatives have looked into the way in which standardized data collection, analysis and evaluation can contribute to the more efficient operation of offshore wind farms and have developed 10 main recommendations. OWI talked to Berthold Hahn, Head of the Department of Wind Farm Planning and Operation at the Fraunhofer IWES, about the compatibility of data, the cost of compilation and fading memory.
