PAUL Tech concludes project financing with Solas Capital
Klaus Schmidtke

Mannheim/Munich, March 4, 2025 – PAUL Tech AG has concluded a project financing arranged by Solas Capital to equip the first 5,000 or so residential units with PAUL Net Zero as a technology solution for local building heating. The installations in the buildings will take place in the first half of 2025. Agreements with customers for a total of 26,000 units were already announced last year. A further 30,000 units are already planned for 2025.
Following the financing of the “PAUL Performance” product by the Solas Sustainable Energy Funds (SSEF) advised by Solas Capital, the successful financing partnership between Solas Capital and PAUL Tech AG is being continued with the financing for PAUL Net Zero.
PAUL Net Zero combines AI-supported energy management systems in the boiler room with heat pumps and photovoltaic systems. The technology significantly improves the energy efficiency of residential buildings up to class A and makes them future-proof for owners and tenants on the way to the heating transition. Equipping properties with heat pumps is subsidized by the Federal Office of Economics and Export Control (BAFA) as part of the Federal Subsidy for Efficient Buildings (BEG).
We are very pleased about the successful completion of the project financing and the innovative collaboration with Solas Capital and all partners involved. This financing is an important step on our way to realizing sustainable and emission-free solutions for existing properties. We will now implement PAUL Net Zero on a large scale and thus make our contribution to a successful heating transition. Owners and tenants alike will benefit from this.
Sascha Müller, CEO PAUL Tech AG
The positive results of the systems already installed in recent months confirm the success of PAUL Net Zero: the heat supply to the houses, most of which were built between 1950 and 1980, runs smoothly after the changeover, even in harsh winter conditions. The outstanding efficiency values - which result in a third of the primary energy requirement - have been further increased through the use of artificial intelligence and deep integration of the heat pump cascade control system.
With the installation of PAUL Net Zero, the direct CO₂ emissions of the buildings are reduced to almost zero. In the CRREM (Carbon Risk Real Estate Monitor) assessment, the degree of decarbonization improves considerably, as the use of heat pumps eliminates dependence on fossil fuels and significantly reduces the specific emissions per kWh of heat provided.
PAUL Tech AG has invested tens of millions in the development of this pioneering technology in the past year alone.
We are very happy to be able to support PAUL Tech AG in its next step towards becoming a supplier of decarbonized heat. The financing for PAUL Net Zero is in line with our corporate goal of saving CO₂ and energy with every investment.
