Whitepaper: Cost savings of flexible electrification

Kraftblock presents the whitepaper on benefits of flexibility and adresses industrial load shifting as a toll to significantly reduce costs.

German Vice Chancellor Habeck visits Kraftblock.

German Minister for Energy, Economics and Climate Affairs and Vice Chancellor Robert Habeck visits Kraftblock to discuss energy storages and the replacement of fossil fuels in industries.

Improving the Carbon Footprint of Hydrogen

Green hydrogen is scarce, yet hydrogen production accounts for 2% of global emissions. Here is how you can reduce the emissions from hydrogen production and how to help green hydrogen to breakthrough.

The Business Model
How to reduce energy costs

A thermal storage in combination with electrification allows for a great cost reduction compared to direct electrification. This is due to the business model of thermal energy storage systems. Unlike with direct electrification, there is a great flexibility in purchasing electricity for the use of process heat.

In the day-ahead or intra-day market, the process heat supply can be aligned with the cheapest available hours. The Kraftblock storage transports the low prices to supply the industry later and avoids peak prices. Thus, operation costs are well below the average.

In case of a PPA, flexibility also helps to improve the prices. As the supplier uses the same market mechanisms, a storage is a great tool for him to store negative prices. Thus, the PPA with flexibility from Kraftblock is cheaper than a normal PPA.

Finally, if an industry has own power generation asset, they can use the surplus in the Kraftblock system instead of selling the electricity for less. This way, they maximize their use of their own energy.

German Energy Agency (dena)

The German Energy Agency (dena) is a centre of excellence for the applied energy transition and climate protection. dena studies the challenges of building a climate-neutral society and supports the German government in achieving its energy and climate policy objectives. Since its foundation in 2000, dena has worked to develop and implement solutions and bring together national and international partners from politics, industry, the scientific community and all parts of society. dena is a project enterprise and a public company owned by the German federal government. dena’s shareholder is the Federal Republic of Germany. www.dena.de/en

German Energy Solutions Initiative

With the aim of positioning German technologies and know-how worldwide, the German Energy Solutions Initiative of the Federal Ministry of Economic Affairs and Climate Action (BMWK) supports suppliers of climate-friendly energy solutions in opening up foreign markets. The focus lies on renewable energies, energy efficiency, smart grids and storage, as well as technologies such as power-to-gas and fuel cells. Aimed in particular at small and medium-sized enterprises, the German Energy Solutions Initiative supports participants through measures to prepare market entry as well as to prospect, develop and secure new markets. www.german-energy-solutions.de/GES/Navigation/EN/Home/home.html

Renewable Energy Solutions Programme (RES Programme)

With the RES programme, the German Energy Solutions Initiative of the Federal Ministry for Economic Affairs and Climate Action (BMWK) helps German companies in the renewable energy and energy efficiency sectors enter new markets. Within the framework of the programme, reference plants are installed and marketed with the support of the German Energy Agency (dena). Information and training activities help ensure a sustainable market entry and demonstrate the quality of climate-friendly technologies made in Germany. www.german-energy-solutions.de/GES/Redaktion/EN/Basepages/Services/dena-res.html
