ECOVAT storing energy from and for buildings

Report on KIVI visit to ECOVAT: HQ in Veghel and production in Oss.

Our host is Aris de Groot, founder and managing director of Ecovat. He starts his introduction on Ecovat with the statement "After the natural gas comes Ecovat!" He stresses that in future the advantages of renewable energies from windmills, solar panels, bio power stations and the like can only be harvested to the full extent if flexible storage of energy is possible at economically attractive prices and lasting for various seasons. With the storage systems known today this is only possible for short periods and not economically acceptable.

The new company Ecovat is promoting an innovative solution for heating and/or cooling of a residential area with a reasonable number of houses. The system contains an impressive and highly insolated water-cask of up to 30 metres high and a diameter ranging from 30 up to 48 metres. The cask is built up with rings of elements having a height of 3 metres and sides under an angle of 12 degrees to make in the ring a proper fit of the elements possible. The use of a four-pipe system enables the supply or storage of water for heating as well as for cooling of a number of houses equipped with e.g. solar panels. A very innovative controlling system ensures proper operation and service to the connected houses.

After some years of evaluation and testing Ecovat is now realising some projects for new residential areas. For details of the system reference is made to the website www.ecovat.eu

After the introduction on Ecovat and the presentation of the new flexible storage system of energy a visit was made to the production location in Oss. The entrance of the location was clearly dominated by rows of construction parts for building the water-cask to be realised next year in the town of Arnhem. At the start of the production the elements for forming the wall of the cask were made in a horizontal mould. Today the elements are produced in an impressive vertical equipment specially designed for Ecovat.
The system will be built in Arnhem during the next months. It was agreed to visit also that building site somewhere next year to see in reality the system and components in a real environment.

For questions

Question can be sent to the organiser of the visit by e-mail webbeheer-el@kivi.nl.

Questions and answers are following (in Dutch) published:

1. What is expensive?

Expensive is a relative term. A €1 pen that doesn't write is expensive. It is simply about the Capex, Opex and efficiency ratio of each technology.

For a project of 1,000 homes, the value of the homes together, say 300,000 euros/home total is 300 million euros.

With a complete 100% sustainable Ecovat system configuration included, you are talking about a total investment of around 315/320 million euros. On amounts like that, that is a manageable and manageable price level. After all, you're talking about around 5% of the total investment. The point is that you include all costs in the assessment. It is always a pity that people make judgements without substantive depth.

a. Annex 2 Lund Renewable heating strategies Smart Energy System Approach

b. Annex 3 Berenschot calculation of avoided system costs

c. Annex 4 Business case validation of Ecovat by DNVGL

2. Costs smallest ecovat: costs EUR 5,593 k. The heat network and other supplies (such as large heat pumps, delivery set, etc.) see appendix 4 page 7 where a calculation was made for a new-build project and a calculation for a renovation project.

3. Only SDE+ subsidy is applied for on the heat collectors. There may be SDE on (seasonal) storage in the future.

Description

Ecovat Seasonal Thermal Energy Storage

To maximise the use of renewable energy, there is a demand for flexibility. The share of sustainably generated energy is growing and with it the demand for flexibility. Energy storage ensures that we can handle our energy flexibly.

However, with the currently known thermal storage systems, energy can only be stored over short periods of time or the realisation is not profitable enough.

The company Ecovat has an innovative solution for heating homes. For details see the following website www.ecovat.eu. After several years of evaluation, they are now realising projects at new housing estates. The Ecovat energy storage system is the missing link here: affordable thermal energy storage across the seasons.

The purpose of an Ecovat in an energy system is to establish balance between supply and demand of sustainable energy by means of energy storage.
The large storage capacity and efficiency make it possible to store energy across the seasons.
This way, Ecovat responds optimally to energy supply and demand.

The company visit consists of a presentation with technical content of the Ecovat, how the system works and is controlled.

Afterwards, we will visit the premises where the components for the Ecovat are made.

Our host is Mr Aris de Groot (Ecovat).
