A new Fraunhofer study shows that gas network fees will increase tenfold by 2045. This is a game changer for the heating transition—and even more so for real estate investors. Those who still rely on gas today risk massive cost increases and losses in value. Digital and electrical solutions such as PAUL Net Zero now offer a clear financial advantage.

A recent Horvath study shows that energy suppliers are increasingly turning away from hydrogen as a solution for residential heating. Instead, they are investing in district heating, large-scale heat pumps, and digital services. This is exactly where PAUL comes in—with a technology platform that is already making existing buildings “green” today, without having to wait for the federal government's hydrogen strategy.
