HighEFF adopted the following criteria and definitions of what constitutes an innovation.
An innovation can be a product, a technology, a component, a process or a sub-process, a model or sub-model, a concept, an experimental rig or a service that is new or significantly improved with respect to properties, technical specifications or ease of use. An innovation can also be new application of existing knowledge or commercialisation of R&D results. The innovation should be adopted by somebody or be ready for utilisation provided that it is made probable that the innovation will be utilised within a limited timeframe.
When an HighEFF innovation is recorded, the probability of success and impact is evaluated simultaneously. If both criteria are high, the development of this innovation will continue with considerable effort.
Energy recovery with integrated thermal storage
The significant quantities and high temperature of the heat rejected during ferroalloy casting makes it an interesting source for energy recovery. The heat released during casting is rarely utilised today.
Cold thermal energy storage (CTES)
Large-scale cold TES for the food industry to balance between high cooling demand and varying availability of low- cost electricity from renewable sources.
Optimal selection of thermal energy storage technology for fossil-free steam production
Methodology for identifying the most cost-efficient Thermal Energy Storage (TES) and power-to-heat (P2H) system for load shifting and exploitation of fluctuating renewable energy sources in steam production.
Flexible offshore oil and gas platform model
Assessing different energy-efficient technologies on a variety of configuration relevant to offshore platforms requires a somewhat generic model. An entirely generic model is not practically feasible. However, a flexible and automated one would prove highly beneficial for various analyses and future use.
Energy Recovery and CO₂ Capture for the Aluminium Industry
Presently, close to 40 % of the waste energy generated from aluminium production by the aluminium industry is lost in the off-gas. Also, the CO₂ concentration in the off-gas is very low, thus, making it difficult for economical carbon capture and storage (CCS) by the industry.
Heat Exchanger test rig
To enable testing of novel heat exchanger prototypes, working fluid mixtures, heat transfer coefficients and pressure drops, a new heat exchanger test rig is constructed in SINTEF and NTNUs thermal laboratories in Trondheim. The rig is designed with a main focus on hydrocarbon working fluids. Heating, cooling, evaporation and condensation experiments can be performed at temperatures from 0 – 150 ˚C and pressures up to 70 bar(g), for heat exchangers with thermal capacities up to 20 - 30 kW.
Improving prereduction behaviour to decrease energy and carbon consumption
The ore-gas reactions occur in today's process at a temperature range favoring the occurrence of the Boudouard reaction causing increased energy and carbon consumption. It further leads to a high-energy off-gas rich in CO(g).
