Newton Energy Solutions

What Newton Energy Solutions does

Newton Energy Solutions is a Dutch energy technology company headquartered in Delft that designs, manufactures, and sells the NEStore Warmtebatterij, a thermal heat battery that converts surplus solar electricity into stored hot water for use days or weeks later. Founded around 2022, the company targets Dutch homeowners with solar panel installations whose economics are set to deteriorate after the planned 2027 abolition of the Dutch saldering (net metering) regime, alongside commercial customers in sports facilities, municipalities, farms, campings, and utility buildings.

The core product is a vacuum-insulated thermal storage unit holding 20-30 kWh of usable heat, achieving less than 2% daily thermal loss compared with 20-40% for conventional boilers and heat pump boilers. The design avoids lithium, is fully recyclable, targets a 30+ year maintenance-free operating life, and integrates with a smartphone app that optimizes charging against dynamic electricity tariffs. The technology was developed in collaboration with TNO, the Netherlands Organisation for Applied Scientific Research, lending third-party scientific validation to the underlying vacuum insulation and storage performance claims.

Newton Energy Solutions operates a hybrid go-to-market: direct consumer engagement through the company website (self-service NEStore Check tool and 15-minute advice call booking) is paired with a certified NEStore dealer and installer network that performs on-site assessments and completes installations in one day. Revenue derives from one-time hardware sales of the NEStore unit plus installation services, with full pricing not publicly disclosed. The company has raised approximately €2.5 million (May 2024) from Carteman Ventures, Fair Capital Partners Impact Investing, König Metall, and TNO, led by Fair Capital Partners Impact Investing, and operates exclusively within the Netherlands.

Direct peers

• Sunamp: UK-based thermal battery manufacturer using phase-change material for residential hot water storage. Directly comparable to NEStore on product category, end-market (homeowners seeking hot water efficiency), and value proposition (decoupling hot water from grid/gas).
• Mixergy: UK smart hot water cylinder with stratified charging designed to maximize solar self-consumption and off-peak tariff optimization. Targets the same residential hot water efficiency use case as NEStore with a comparable technology approach (intelligent water storage).
• Triple Solar: Dutch company offering PVT (photovoltaic-thermal) panels integrated with a heat pump for home heating and hot water. Targets the same Dutch residential energy transition customer, with overlapping GTM and overlapping regulatory tailwinds (saldering abolition, gas reduction).

Broad incumbents

• Remeha: One of the largest Dutch heating manufacturers (part of BDR Thermea Group), producing boilers, heat pumps, and hot water solutions. Dominant incumbent in the Dutch residential heating market that Newton must displace or partner with.
• Intergas: Major Dutch boiler manufacturer specializing in high-efficiency gas combi boilers for residential hot water and heating. Direct competitor for residential hot water heating budget and installer relationships in the Netherlands.
• Itho Daalderop: Dutch company offering heat pumps, solar boilers, ventilation, and hot water solutions for residential and light commercial markets. Overlapping product portfolio and Dutch market focus with Newton.
• Bosch Thermotechnology: Global heating and hot water manufacturer with strong Dutch presence via the Nefit brand. Offers boilers, heat pumps, and hot water tanks, and is a major incumbent in residential heating across Europe.
• NIBE Energy Systems: Swedish manufacturer of heat pumps and water heaters, one of Europe's largest residential heating companies. Competes directly for the residential hot water + heating budget and is a key channel through which Dutch households decarbonize.
• Vaillant: German heating manufacturer offering boilers, heat pumps, and hot water solutions across Europe with a strong Dutch presence. Established incumbent competing for the same residential hot water retrofit opportunity Newton targets.
• Daikin: Japanese global HVAC and heat pump leader with significant Dutch operations. Daikin's heat pump systems address both space heating and hot water, positioning it as a primary substitute solution for the customer pain points Newton targets.
