  1. 21. Photocatalytic generation of hydrogen from cellulose

    University essay from KTH/Kraft- och värmeteknologi

    Author : Stefano De Luca; [2022]
    Keywords : ;

    Abstract : Uncontrolled emission of greenhouse gases caused by consumption of fossil fuels has led to the urgent need to develop low-emitting energy technologies such as those exploiting renewable energies. In this context, hydrogen (H2) represents an opportunity to enhance the development of such technologies, in light of the possibility to use it as an energy storage for non-programmable renewables, and for its potential to decarbonize key emitting sectors such as transport sector.

  3. 22. Energy improvement options for a small-scale brewery: a literature study

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Eneko Arana; [2022]
    Keywords : Brewing industry; energy audit; energy efficiency; environmental impact; sustainability and energy recovery.;

    Abstract : In the age of technology and development in which we live nowadays, it is inevitable to realise that this so-called progress is translated into pollution, damage to the environment and abuse of energy and fossil fuels. The companies and factories that produce the goods we need, use a lot of energy and pollute in massive ways, posing dilemmas such as how to make these companies more energetically and environmentally efficient, with the aim of decreasing the emissions and energy use.

    Abstract : In the countries willing to follow an energy transition towards decarbonization, a strong emphasis is put on electrification. Carbon-free power production tends to rely more on intermittent renewable energies, bringing many uncertainties on the electricity output to the grid. READ MORE

  6. 25. Energy supply system for a high-rise building in Germany : Optimization of a heating and cooling supply system made with plant simulations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Ida Almén; Elin Johansson; [2022]
    Keywords : energy supply system; absorption chiller; compression chiller; Germany;

    Abstract : The building sector has great potential for energy savings since it is responsible for nearly a third of the global energy use. As oil, coal and natural gas continues to hold a big share of the energy mix it is important to work towards introducing more renewable energy alternatives. READ MORE
