Hungarian startup provides PCM-based thermal battery with vitality density of 30 kWh/m3 – pv journal Worldwide


Hungary-based Heatventors provides its new thermal vitality storage techniques with capacities of 10 kWh, 30 kWh, and 60 kWh. The thermal battery will probably be mixed with photo voltaic PV and has an anticipated service lifetime of over 10,000 cycles.

Heatventors Ltd. based mostly in Hungary has developed a non-flammable thermal vitality storage system that may report can save as much as 90% area in comparison with conventional storage applied sciences or water tanks.

“Our thermal battery can retailer vitality with a excessive vitality density of 30 kWh/m3,” stated the corporate’s CEO and founder Christoph Thomas. pv journal. “It may be built-in into the cooling and heating system of any constructing the place a liquid circulates within the system, which is right for top vitality consumption buildings reminiscent of accommodations, knowledge facilities, industrial premises, medical services, and places of work.It can be utilized in varied processes reminiscent of wine cooling, beauty manufacturing, and cooling processing machines and ovens.

According to the producer, the thermal battery can be utilized in mixture with a PV system, as a result of it might retailer the surplus vitality generated by the photo voltaic panels and use it when it’s most wanted. “Another benefit is that, even with PV, we will nonetheless preserve the specified temperature.”

The system relies on a non-specific kind of part change materials (PCM). PCMs can absorbs, shops, and releases giant quantities of latent warmth over specified temperature ranges. It is usually used on the analysis degree for PV module cooling and the storage of warmth. The battery can reportedly retailer vitality between -30 C and 120 C for lengthy intervals of time with solely 1-2% vitality loss per day.

Heatventors provides the system with a capability of 10 kWh, 30 kWh, and 60 kWh. It may be put in indoors and open air and “simply” related to any liquid-based cooling and heating system. “It may be related to any system if the top use is cooling or heating, and has an vitality converter that converts electrical vitality,” explains Thomas.

The firm additionally claims that the system has an anticipated service lifetime of over 10,000 cycles. “Our battery can guarantee ample vitality storage by means of a proprietary management system,” added Thomas. “This reduces consumption peaks, operating vitality producers with the very best partial load, which reduces upkeep prices.”

He additionally defined that the corporate is presently engaged on a brand new 1.2 MWh model of the system. “The modular construction of our answer ensures that each one capability necessities may be met,” he stated.

“The pricing largely is dependent upon the system necessities, however expertise exhibits that the return on funding is roughly 3-6 years, relying on the vitality worth,” concluded Thomas. “Currently, we’ve got greater than 40 put in batteries around the globe in international locations reminiscent of Hungary, Portugal, France, Spain, Italy, and Oman. Our essential shoppers are the key areas that constructing, reminiscent of places of work, accommodations, buying malls, factories, knowledge facilities, and any facility with important cooling and heating necessities.
