Founded

2011

Size

Approximately 40 employees across European offices including Hamburg, Oslo, Rotterdam, Madrid, and Seville (source: linkedin.com)

What They Do

ENERGYNEST develops and delivers industrial power-to-heat and thermal energy storage systems designed to provide industrial heat more cost-effectively than gas while ensuring high operational reliability (source: energy-nest.com). Their core technology package combines power-to-heat, thermal energy storage, and continuous energy market optimization, enabling customers to generate heat when electricity is cheaper than gas and store it for later use (source: energy-nest.com). The patented ThermalBattery™ technology uses high-performance thermal concrete with embedded heat exchangers to store heat on a large scale (source: energy-nest.com).

The systems are specifically designed for energy-intensive industrial heat consumers requiring process heat or steam in the range of approximately 120°C to over 300°C. Typical customers have an annual heat demand exceeding 5 GWh and a grid connection capacity of about 1 MW per 5 GWh of heat demand (source: linkedin.com). ENERGYNEST offers its solutions both as Heat-as-a-Service with zero upfront investment and as turnkey EPC projects, handling planning, financing, operation, and optimization as a long-term partner (source: tesa.com).

Additionally, ENERGYNEST serves customers in power generation and renewable energy sectors, including large-scale energy storage solutions for solar thermal and other emission-free power plants (source: energy-nest.com). The combination of thermal storage, electricity market optimization, and industrial operational expertise, along with a business model that can reduce heat costs to or below the level of natural gas, distinguishes the company (source: energy-nest.com).

Projects & Track Record

ENERGYNEST's most notable project is the collaboration with tesa in Hamburg, where a large-scale power-to-heat plant with integrated thermal storage is being implemented at tesa's largest production site (source: tesa.com). The system features 10 MW power-to-heat capacity and 40 MWh thermal energy storage, covering about two-thirds of the site's annual steam demand and aiming to reduce emissions by approximately 4,600 tons per year. Construction is scheduled to begin in fall 2026, with commissioning planned for summer 2027 (source: tesa.com).

Other projects include a 30 MWh thermal energy storage system with 8 MW electric steam generation, indicating further integrated industrial heat solutions in the portfolio (source: energy-nest.com). According to company information, at least three to four projects are currently under construction, along with a proven pilot (source: energy-nest.com).

Additionally, ENERGYNEST completed a project with LEONHARD KURZ and a new electric steam generation plant at Peter Greven's site in Bad Münstereifel, highlighting its active presence in German industrial applications (source: energy-nest.com).

Recent Developments

In January 2025, Alex Robertson was introduced as the new CEO of ENERGYNEST, set to lead the company’s next growth phase starting February 2025 (source: energy-nest.com). The same announcement confirmed ENERGYNEST as a global market leader in thermal energy storage solutions, focusing on industrial process heat and large-scale storage for solar thermal and other emission-free power plants (source: energy-nest.com).

In January 2026, the major project with tesa in Hamburg was publicly unveiled, including technical specifications, expected emission reductions, and the planned commissioning date in summer 2027 (source: tesa.com).

In September 2026, ENERGYNEST published an update on the commissioning of the project with LEONHARD KURZ and reported on the new electric steam generation plant at Peter Greven in Bad Münstereifel (source: energy-nest.com).
