Heat Storage for Cooking: A Discussion on Requirements and Concepts
(Peer reviewed; Journal article, 2023)Methodologies for direct and indirect solar energy for cooking are discussed. Clean and renewable energy solutions for cooking are, in particular, in demand in the sub-Saharan region where fuel wood is the main source of ... -
Heat Storage for oil based solar concentrators
(Master thesis, 2012)As the world’s energy demand increases, more and more focus is directed towards different solar energy solutions. In many African countries, a great share of the population cook their food with firewood as the energy source. ... -
Heat Storage for Vapour Based Solar Concentrators
(Master thesis, 2012)In a world where energy demand, population, and environmental concern are increasing by the day, the use of solar energy and other renewable energy sources becomes ever more important. Most of the African population lives ... -
Heat stress response is part of the isothiocyanate-induced response in Arabidopsis thaliana
(Master thesis, 2016)Heat stress responses (HSR) represent a multi-pathway system of adaptive responses to environmental changes. Common downstream targets of HSR pathways are the heat shock proteins, amongst them HSP101 (At1g74310). In ... -
Heat to H2 - Hydrogen production in a closed loop RED-system

Heat to H2: Using Waste Heat for Hydrogen Production through Reverse Electrodialysis
(Journal article; Peer reviewed, 2019)This work presents an integrated hydrogen production system using reverse electrodialysis (RED) and waste heat, termed Heat to H2. The driving potential in RED is a concentration difference over alternating anion and cation ... -
Heat to H2: Using Waste Heat to Set Up Concentration Differences for Reverse Electrodialysis Hydrogen Production
(Journal article; Peer reviewed, 2018)The present work suggests two concepts for producing hydrogen by reverse electrodialysis. Reverse electrodialysis is a technology that uses concentration differences to create electrical energy. In this work, the energy ... -
Heat to Hydrogen by RED—Reviewing Membranes and Salts for the RED Heat Engine Concept
(Peer reviewed; Journal article, 2022)The Reverse electrodialysis heat engine (REDHE) combines a reverse electrodialysis stack for power generation with a thermal regeneration unit to restore the concentration difference of the salt solutions. Current approaches ... -
Heat to Hydrogen by Reverse Electrodialysis—Using a Non-Equilibrium Thermodynamics Model to Evaluate Hydrogen Production Concepts Utilising Waste Heat
(Peer reviewed; Journal article, 2022)The reverse electrodialysis heat engine (REDHE) is a promising salinity gradient energy technology, capable of producing hydrogen with an input of waste heat at temperatures below 100 °C. A salinity gradient drives water ... -
Heat tolerance during uncompensable heat stress in men and women wearing firefighter personal protective equipment
(Peer reviewed; Journal article, 2022)Firefighters run a risk of heat strain during occupational tasks. The number of female firefighters has been increasing, but research relevant to this group is still scarce. We aimed to investigate whether there are any ... -
Heat transfer and pressure drop characteristics of the silicone-based plate heat exchanger
(Journal article; Peer reviewed, 2019)The paper presents an experimental investigation of a silicone based heat exchanger, with passive heat transfer intensification by means of surface enhancement. The main objective of this paper was to experimentally ... -
Heat transfer and pressure drop of supercritical CO2 in brazed plate heat exchangers of the tri-partite gas cooler
(Peer reviewed; Journal article, 2021)The heat transfer characteristic of supercritical CO2 is an essential research topic due to its significant influence on the performance of heat exchangers and systems. In this paper, the heat transfer and pressure drop ... -
Heat transfer characteristics of CO2 condensation on common heat exchanger materials, method development and experimental results
(Peer reviewed; Journal article, 2021)Understanding condensation of CO2 is essential for e.g designing compact heat exchangers or processes involved in Carbon Capture and Storage. However, a consistent experimental campaign for condensation of CO2 on common ... -
Heat Transfer Characteristics of Crushed Rock and Lightweight Aggregate Materials
(Doctoral theses at NTNU;2018:228, Doctoral thesis, 2018)Over the last decades there has been a major transition to using crushed rock materials for road and railway construction instead of natural materials such as sand or gravel. In addition, it is common practice to use very ... -
The heat transfer coefficient similarity between binary and single component flow condensation inside plain pipes
