      During the operation of combustion or incineration plant the properties of ash has a major impact on the availability and operational cost of the systems. We will provide methods of how to optimise the operation with regard to ash problems. This is a topic which is on our list to be completed as soon as possible. We will send a post here as soon as the topic is online. So, please tick the notification box below to be informed when the topic is ready.

        WHY

        Why do we need the www.alera.academy?

        The global energy transition towards an electricity dominated energy world created by renewable energy, mainly wind and solar, is well underway. In some countries, wind and solar are already contributing a notable portion of the electricity production. By this transition, the interest in thermal energy is declining and material and intellectual resources are increasingly diverted from thermal energy technology to electricity from renewables. Some university institutes for thermal engineering are faced with strongly reduced numbers of students or they even close thermal energy departments

        However, if one looks at the total global primary energy usage, the picture looks less promising.

        Evaluating the last 17 years, the period after the Kyoto protocol signed by 192 nations went into force in 2005. we see that the actual contribution of wind and solar energy to cover the global primary energy consumption is neglectable.

        In this period the global primary consumption of energy increased by 26,3 % and the largest amount of this increase  with 70 % was provided by coal, oil and gas. Wind and solar contributed only 20 % of the increase and hydropower 8 %. 

        In 2021 wind and solar energy only provided 4,3 % of total global primary energy.

        The contribution of the different energy sources to the global primary energy is shown below.

        (source https://ourworldindata.org/energy-mix). 

        The fact that wind and solar energy have a high convertion factor to  electricity is already accounted for in the above numbers chart. Nuclear is shown with its thermal input, not electricity produced and hydro is adjusted for efficiency as present in a thermal power plant.

        The idea that additional energy consumption growth or the globally required energy  will in the short to medium future, say 50 to 100 years, be in its majority provided by wind and solar and the rest by other renewables such as hydro or nuclear with a suitable grid and energy storage system is nothing but an illusion.

        This is why we are conviced that we must upkeep and further develop thermal energy knowledge, and so utilise the enormous potential energy saving  through efficiency increase and better thermal energy processes.
