Berenschot research report endorses opportunities for mini turbines
Our energy system is moving towards a more sustainable future. During the COP21 in Paris, 192 countries voted in favour of limiting global warming to well below 2 degrees Celsius.This means that, by 2050, measures must have been put into placeto reduce carbon emissions by 80-95% when compared to 1990.
According to the Berenschot research team, energy transition currently poses a huge challenge for the Dutch industry, especially concerning industrial heat demand. At present, few solutions are available to ensure the decarbonisation of high temperature heat supply.
Mini turbine principle
The mini turbine principle offers a new solution, however: ‘A carbon-lean concept in which highly efficient electricity is produced by using the demand for steam. The principle is easily applicable and proves to be lean in emissions and cost’, according to the report.
The researchers are referring to the innovative concept of a mini turbine, developed by Innecs Power Systems. This mini turbine has remarkable properties, allowing electricity to be generated extremely efficiently, and thus achieving a short payback period.
The conclusions of the research report are clear:
- Energy transition poses a huge challenge for the Dutch industry, especially concerning industrial heat demand. At the same time, there is increased demand for sustainable electricity, which puts pressure on the available energy sources.
- In industrial applications, mini turbines offer the possibility of combining efficient heat production with the generation of electricity. This solution not only reduces the total number of required electricity resources but also renders the entire energy system more sustainable.
- Mini turbines convert a large share (~ 86%) of energy into process steam and a small share (~ 9%) into electricity. This means they are able to generate electricity at a marginal gas-to-power efficiency of approximately 90%. The concept is suitable for small to medium-range industries, for which a carbon neutral solution is not (yet) feasible. If the full potential of mini turbines could be implemented in the Dutch industry, this would contribute to a reduction of 1.3 million tons of CO2.
- Thanks to its unique properties, a mini turbine can compete with the conventional technologies, both in terms of cost and sustainability. The amount of carbon emitted by the production of electricity using mini turbines is 1.75 – 4 times lower than that of gas or coal production plants.
Innecs Power Systems recently developed a mini turbine – the MiniSTEG –, which is a combination of two technologies: the PowerBurner and SteamExpander. The MiniSTEG offers a solution that:
- can be applied in various industries
- is sustainable because it reduces the carbon footprint of the industrial demand for electricity
- is financially sound
- is flexible
