Balancing energy – storage of regenerative power in thermal energy
Due to the growing share of renewable energy generation, which cannot be controlled in the case of the most important energy sources, wind and sun, and the displacement of controllable thermal power plants, balancing generator and consumer output is becoming increasingly challenging.
These rapid and large fluctuations in generation pose ever greater problems for grid operators, as they must guarantee electricity customers good energy quality, i.e. stable voltage and grid frequency. In the worst case, there is a risk of a power failure.
The major challenge posed by the increasing share of renewable energies in the energy mix is therefore to balance the fluctuating demand for electricity with the even more volatile supply of wind and solar power. Flexible solutions for rapid load changes and the stabilisation of frequency fluctuations (control power) are required.
Why are energy storage systems necessary?
Wind and solar energy do not always generate the same amount of power. In order to be able to use surplus energy later, storage systems, e.g. in the form of hot water tanks, are useful.
Intelligent use of surplus energy with power-to-heat technology
- Stabilisation of frequency fluctuations in the power grid as a source of potential added value
- High flexibility in responding to load fluctuations
- Use of surplus renewable electricity by converting it into thermal energy (direct feed-in to local or district heating networks)
- Storing energy (as thermal energy in hot water storage tanks)
- Generating process heat economically
- Opportunities in the control energy market for lucrative additional revenue
- Savings in fossil fuels and CO2 reduction
Electric heaters are particularly suitable as flexible control energy capacity.
- Decades of operating experience with this proven technology.
- Fast response time between power request and reaching full load (< 5 min).
- Many years of routine mechanical and electrical installation.
- Low maintenance (no moving, rotating parts) that cause wear No emissions (noise/exhaust gases)
- Increased operational safety with redundant heat generators (in addition to fossil fuel-fired heat generators)
- Precise temperature and power control
- High efficiency in the conversion of electricity to heat (> 98%)
