Energy technology firm Delta Green, formerly known as Nano Green, has announced the completion of a major €2.2 million financing. Three venture capital firms—Tilia Impact Ventures, which is leading the investment, Credo Ventures, and Purple Ventures—are supporting it. The money is intended to support the company’s growth into Western Europe and enable it to provide a more comprehensive sustainable energy management program for homes.

Co-founder of Delta Green Jan Hicl stated, “Our goal is to become a catalyst for innovation in household energy across Europe, and this investment represents a significant step towards that vision.” “We have designated the funds for three primary purposes: completing the software development to enable household participation in grid balancing, growing our business into Western Europe, and adding new personnel to our team, mainly in the software development domain.”

This week, Delta Green and representatives from Tilia Impact Ventures, Credo Ventures, and Purple Ventures closed the financing arrangement. This cooperation was arranged by Tilia Impact Ventures, which is committed to projects that tackle the most pressing social and environmental issues of the day and shares Delta Green’s values.

“In order to clean up the carbon footprint of our energy sector, we need more renewable sources on the grid. But wind and sun are unpredictable and this creates energy fluctuations which must be balanced out,” said Andrew Gray, General Partner at Tilia Impact Ventures. “Delta Green has developed a low-cost solution to this problem, and we believe that this could be a key puzzle piece in enabling more renewable energy generation and lowering the cost of electricity for everyone. We’re excited to partner with them in taking this global, ” added Gray.

As an energy flexibility aggregator, Delta Green is at the forefront of innovation in the energy industry. Its solution makes it possible to massively integrate renewable resources into the grid without jeopardizing system stability. The company’s goal is to integrate homes into grid balancing by grouping them into a massive virtual battery. Homes with electric vehicles, heat pumps, photovoltaics, or batteries can earn or save hundreds of euros a year with Delta Green. This entails planning the intended integration of houses into grid balance in addition to controlling electricity output and consumption. Currently, fossil fuel power plants dominate this billion-euro sector. And they are the very ones that the creative minds at Delta Green want to swap out for homes.

The last four months have been a blur of activity for Delta Green. The business quickly reported a successful pilot test incorporating household participation in grid balancing after a change in ownership at the beginning of the year, demonstrating the game-changing potential of their solution, which is anticipated to be completely available by year’s end.

“As our initial move, we’re introducing the service to Czech households, aiming to aggregate tens of megawatts,” explained Delta Green’s co-founder David Brožík. As Delta Green expands into Europe, they’ll be handling hundreds of megawatts. That’s why it’s crucial to develop a robust and stable solution now, which will help replace fossil fuel sources with electricity that’s currently being wasted in households. They estimate they’ll only need about 200 households per megawatt.
