What we do?

For battery providers

The power grid cannot store energy, so consumption and generation must be equal at all times. This is achieved by electricity markets operating on multiple timescales. Day-ahead and intraday markets operated by power exchanges such as Nord Pool and EPEX are a market driven solution for planning beforehand how buying and selling of electrical energy are matched. However, generation and consumption cannot be perfectly forecasted and unexpected outages or consumption peaks can occur. Ancillary markets operating at different timescales are a solution for reacting to grid disturbances as they occur.

Transmission system operators procure reserve resources beforehand, which are compensated for standing by and being ready to react quickly to grid disturbances. The replacement of fossil fuel generation with wind and solar generation greatly complicates the grid balancing problem and thus increases the need for reserve resources. As battery prices have come down, batteries have emerged as a highly suitable kind of reserve resource that is capable of quickly reacting to grid disturbances. Operating stand- alone batteries on reserve markets is currently a profitable business. Additionally, many companies are developing grid-scale batteries co-located with other resources such as solar or wind generation or electricity consumers such as commercial buildings or industrial processes. Such co- located assets are able to capitalize on price fluctuations in the Nord Pool or EPEX markets.

For heat storage providers

A large portion of energy consumption in Europe is from the generation of steam for industrial processes. The main energy sources have been fossil fuels and biomass. To decarbonize, the heat generation is being electrified either by boilers or other more innovative solutions involving heat storage mediums such as molten salt, sand or concrete bricks. In each case, the solution consists of a heat generation component and a heat storage component. If the heat generation is electrically powered, the storage capacity can be used to permit the profitable scheduling of the heater on multiple electricity markets. Depending on the ramp rates, the heating element can generate additional revenues from ancillary markets, especially aFRR.

OptiBidTM prototypes support the scheduling of any electrical heating element across all applicable electricity markets while ensuring uninterrupted heat delivery to process steam generation, according to the heat offtake required by the customer. Further extensions of OptiBidTM are possible to consider gas prices and the utilization of any redundant gas-powered generators on site.

For renewable power and H2/P2X producers

Due to massive investments into wind and solar generation, electricity prices can be very low or even negative during generation peaks. Battery storage will solve this problem at least partially, but this requires investment into immense battery fleets. Another approach is to use electrically powered electrolyzers for green hydrogen production. The hydrogen can be used locally at a hydrogen refueling station, or it can be consumed by an onsite industrial process, or it can be transported short distances with tube trailers. The hydrogen can also be refined further to products that are easier to store and transport, such as ammonia or methanol, to be used for example in the marine industry.

A fuel cell can also be used to generate electricity from the hydrogen. However, significant energy losses are incurred in all of these conversions, and the situation with regulations and subsidies is unclear, so the business case for green hydrogen has major uncertainties, with most projects still in early stages without a final investment decision. OptiBidTM prototypes have shown good performance in scheduling the electrolyzer, considering the varying efficiency of the electrolyzer at different loads. Some aspects of the local hydrogen logistics have also been included to the optimization. We have demonstrated the profitable cross-market bidding of the electrolyzer on the aFRR market, but there is still work to do by electrolyzer vendors to prequalify for reserve markets. We have also optimized a renewables site with battery storage and an electrolyzer.
