Switzerland-based energy provider Energie 360° AG and the Netherlands-headed "green and clean" hydrogen company Tree Energy Solutions B.V. (TES) have signed a Letter of Intent (LoI) regarding the supply of 1 TWh of renewable electro-synthetic methane (eSNG) annually from 2027.
Tree Energy Solutions (TES) aims to supply its customers exclusively with renewable energy by 2040.
The main goal of TES is to accelerate the energy transition by using existing global energy infrastructure to supply customers with renewable electro-synthetic methane (eSNG).
This is produced by combining green hydrogen and carbon dioxide (CO2).
TES aims to supply Energie 360° with around 1 TWh per annum of eSNG from 2027 while Energie 360°, in return, intends to supply renewable CO2 from its own energy plants to TES.
This creates and maintains a circular closed loop.
eSNG for industry
Majority owned by the City of Zurich which holds a 96 percent share, the company supplies the metropolis – and 42 other communities – with increasing amounts of renewable energy.

The municipal energy company is charged with the planning, building, and operation of various energy solutions and works with customers, partners, and communities to promote renewable energy and eco-mobility including electric charging stations, and is a supplier of biogas and wood pellets.
Fossil gas is being used less and less for heating or cooking in Switzerland. Energie 360° is therefore already implementing systems that use renewable energy sources, such as energy networks or integral solutions.
In the future, there will still be industrial companies that need gas – especially for special high-temperature applications – but we want to offer this gas completely from renewable sources. The transformation of the energy system from fossil to renewable is a major challenge. We look forward to working with TES and believe that the partnership we are seeking can contribute as an important piece of the energy transition puzzle, said Dr Jörg Wild, CEO of Energie 360°.
Zero-emission energy cycle
TES uses recycled CO2 as the transport medium for green hydrogen. The CO2 is captured at the source and then transported to locations where it can be combined with green hydrogen to create eSNG.
This creates a closed, emission-free energy cycle.
We are pleased to support Energie 360°’s efforts to decarbonize by offering them cost-effective, green energy. Energy suppliers play a critical role in the energy revolution realizing the goal of net zero and actively contributing to a truly circular economy, said Marco Alverà, CEO of TES.
