Potential Analysis of On‐Site Oxygen and Ozone Production for Wastewater Treatment Plants

Chemie Ingenieur Technik, EarlyView.
The potential of a power‐to‐gas process focusing on the oxygen stream to cover an upcoming demand of ozone at German wastewater treatment plants is analyzed. Economic and ecological parameters are compared to the conventional production of hydrogen and oxygen. Powered by on‐site produced wind energy, the process is deemed beneficial.

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Defossilisation of the Energy Supply of a Chemical Site by Integration of a Carnot Battery

Chemie Ingenieur Technik, EarlyView.
This study presents the results of a techno‐economic analysis of CO2‐free energy supply concepts for electricity and heat for the defossilisation of a chemical park in Germany for the model years 2030 and 2045. The focus is on the integration of a Carnot battery with thermal energy storage, which enables the flexible use of green fuels and renewable ...

Energy Flexibilization and Demand Response for a Novel Decentralized Power‐to‐Methanol Process

Chemie Ingenieur Technik, EarlyView.
This study presents the results of an optimization framework for the scheduling of a Power‐to‐methanol process coupled with an electrolyser, renewable energy sources and a battery. The optimal dynamic operating schedule is computed with different configurations and boundary conditions, showing the advantages of flexible operation.
