Thread by @EU_BUILDUP

Our #BUwebinar on the @CREATEproject1 is about to start, join us to discuss the possibilities of heat storage!

Or keep up through this thread ⬇️
#CREATEproject #EnergyStorage #RenewableEnergy

Let's begin with @AEE_INTEC Technology Development Department Leader Wim van Helden!

"Revolution in thermal energy storage", here we go 💪
#CREATEproject

CREATE stands for „Compact REtrofit Advanced Thermal Energy storage“

The #CREATEproject aims to tackle the thermal energy storage challenge for the built environment by developing a compact heat storage.

The aim is to develop a heat battery that fits the following conditions:

Let’s look into the main components of the design of a CREATE-storage system:
🔴a cluster of batteries
🟠 a water storage
🟡a thermal system
🔵a condenser
...

How does this work?🤔

The heat storage principle relies on the separation and reunion of 2⃣ elements:
🧂Salt hydrate
☁️Water vapour

Results:
🧱Stable salt hydrate storage material (cost<€1,6 per kg).
🏗️Prismatic storage modules, with storage density better than 115 kWh/m3 (virtually no losses)
🏠System demonstrated in a real house
🔢Cost reduction study
#⃣Further cost reduction needed and possible

We move to Heat storage expert Dr. Ir. Henk Huinink from @TUeindhoven to discuss the development of the storage material.

How can the #CREATEproject reach its goals?

🧱Identify low cost base materials with a high energy density
👩‍🔬Develop and characterize stable materials (composites)
🗺️Develop industrial scale production process
🔎Perform economic study of industrial scale process

Let’s take a look at the cost analysis:

Cost evaluation

Original aim reached?
Develop a compact and stable storage material to be produced at industrial scale at low cost.

Results are encouraging:
✅Compact: 1.3 GJ/m3, 3.6 kWh/m3 at particle level
✅Stable: 100+cycles
✅Industrial scale production: yes
✅Material costs: ~ 1.6 €/kg

Let's hear about the "performance of a small-scale test reactor" with @TNO_Research systems engineer Laurens van Vliet.

📷Take a look at the small test reactor:

📷After 5 cycles with the set up, material is affected by the heat process.

Samuel Knabl from @AEE_INTEC will share on system design of thermal storage systems.

Let's review the Storage System Concept:

💧Long-term heat storage for hot water preparation and space heating
☀️Solar thermal collectorsfor loadingthe TCM storage
♨️Heat pump as a supplementary heating system

How does the storage works in practice? ⬇️

CREATE Storage System key facts:

Modular expandable storage module
Central "corrugated tube" -evaporator/ condenser
Pumped system
Correlation between temperature and power
Maintenance-free operation, no material degradation
2.766W Avg. heating power
115kWh/m³ Storage density

Time for the concrete example with Juliusz Zach - Head of R&D department of Mostostal Warszawa.

Let's look at the #CREATEproject system in real conditions - a single-family house in Warsaw 🇵🇱 !

Let's review the timeline of the #CREATEproject:

🏠Meet the house: located in Warsaw 🇵🇱, with conventional heater and boiler, place for solar collector, and a garden to store the heat exchanger.

And now the inside of the system! 🤩

The last session of today´s webinar is on the "Market potential" of heat storage, by Filip Fišer from @FENIXTNT_CZ.

The building sector accounts for the largest share of energy consumption(approx. 4⃣0⃣%in EU).

Energy storage is a key in providing flexibility and supporting renewable energy integration in the energy system and can efficiently contribute to the decarbonization of buildings.

Several countries were identified as the ones with the biggest potential: 🇩🇪🇫🇮🇦🇹🇸🇪🇧🇪🇩🇰🇨🇾

What criteria? Household energy consumption, newly installed solar thermal capacity, recent development of solar thermal markets, general solar energy potential among the EU states, etc...

Thermal storage has a big market potential.

When extrapolated to the potential global market for thermal energy storage to the current global population, the overall market value for thermal energy storage systems in 2030 and 2050 might even grow to multiple times the number.

Market barriers to heat storage:

🔎Short-term testing of standards for validation of reliability and safety
🤷Low users confidence
⚡️Limited experience regarding balancing the electricity grid by converting to heat storage
📑Slow government acceptance of grid integration

Q&A time!

Thank you for your attention!😀
