Thermal Batteries Revolutionize Solar Energy Storage in the Netherlands
Netherlands, Monday, 13 January 2025.
A new thermal battery technology using salt offers an efficient solution for storing excess solar energy in the Netherlands, enhancing sustainability and reducing reliance on traditional energy grids.
Innovative Storage Solution
Dutch energy companies are introducing groundbreaking thermal battery technology that transforms excess solar power into stored heat using salt. The SGR (Smart Grid Ready) technology integrates solar panels, batteries, and heat pumps to optimize self-generated electricity usage [1]. This system demonstrates remarkable efficiency, consuming 75% of its energy from ambient air and only 25% from electricity [1].
Cost-Effective Alternative
The thermal battery solution presents a significant financial advantage over traditional energy storage methods. An SGR-warmtepompboiler costs approximately €3,500 including installation, making it substantially more affordable than conventional 14 kWh home batteries priced around €10,000 [1]. The system can heat water from 45°C to 70°C, storing excess solar energy for later use [1].
Technical Specifications and Performance
The technology comes in various sizes to suit different needs. The smallest model, the 150 XXS, offers 7 kWh capacity and weighs 136 kg, while the largest 300 S model provides 14 kWh capacity [1]. The Flamco 200 battery demonstrates practical utility by providing approximately 45 minutes of showering time, with a recharge period of about two hours [1]. Importantly, these systems are environmentally friendly, containing no toxic substances and being 100% recyclable [1].
Government Support and Future Implementation
The Dutch government is actively supporting this transition through the Energy Investment Deduction (EIA) scheme, which allows businesses to deduct 40% of investment costs for qualifying energy-saving equipment from their taxable profits [7]. This initiative promotes the adoption of sustainable energy solutions while helping reduce CO2 emissions [7]. For those interested in learning more about these systems, an informative presentation about thermal batteries is scheduled for January 14, 2025, at the WIJcafe in Delft [3].
