High temperature heat pumps will reduce CO2 emissions and lower energy use
Some industries require temperatures of between 100 and 180 degrees. A high temperature heat pump is able to deliver this, so it has great commercial potential. The reduction of climate gas emissions is a global challenge for todays and future generations to minimize the impact…
From cozy woodstove to sustainable and healthy woodstove technology
Hopefully my PhD project will contribute to a sustainable woodstove future, where the impact on climate is mitigated and the air quality will be improved, which will improve people’s health and quality of life. I am researching woodburning stoves, and the impact they have on…
Battery testing: developing a new computational tool to reduce experiments
Battery behavior is best studied through experiments. However, time-consuming cycling tests are required to ensure that a specific battery design will perform well over its entire life. I aim to develop a new computational tool for long-term battery testing. My PhD project aims to develop…
Green energy: Hydraulic Machinery and Systems
A post symposium summary of the 31st Symposium on Hydraulic Machinery and Systems (IAHR 2022) in Trondheim. The Symposium on Hydraulic Machinery and Systems, widely known as IAHR symposium within hydraulic machinery community, is organized every second year. It is organized under the framework of…
Making heat pumps hotter to reduce CO2 emissions
Food processing, battery production and other industriall processes all demand heating and cooling at the same time. Improving high temperature heat pumps will reduce both energy use and CO2 emissions for these and other industrial processes, and the objective of my PhD is to develop…
We need to find more efficient ways to recycle metals
Metals are less available than before, and a lot of them come from geopolitically critical areas. I investigate a way to make metal production more sustainable, through recycling. We have been facing the limits of growth for a long time, and that strongly affects the…
Saving up solar heat for cooking
Can you believe that during our series of tests, the maximum temperature reached so far is 173 degrees Celsius? Despite the challenges with the weather in Trondheim? My name is Casiana Blasius Lwiwa, and I started my PhD period at NTNU in 2019. The research…
Capturing CO2 from thermal power plants with a..bed of gravel?
To mitigate the effects of global warming, we need to change the way the world produces electricity. This will likely involve both more renewable energy in the grid and the capture of CO2 from power plants. I am researching how we can reliably capture CO2…
Plastic waste in the ocean: making impact models
Human activities affect the ecosystems of the ocean through different types of pollution such as plastic. However, we lack models to understand the impacts of plastic pollution and how they can be reduced. In my project, I make models for the impact of marine animals…
New book on lower temperatures in heat distribution networks
In our new guidebook on low-temperature district heating implementation, we propose a toolbox. Our guidebook contains aggregated information about the main economic drivers for low-temperature district heating. It shows how to obtain lower temperatures in heating systems inside existing and new buildings, as well as…
