Renewable natural gas for the pipelines Europe already has

TURN2X builds modular plants that combine green hydrogen with biogenic CO2 in a honeycomb reactor. The result is e-methane, chemically identical to fossil natural gas, produced to RFNBO rules and sold through long-term offtake contracts.

Antwerpen Ventures leads the round, joined by existing investors LEA Partners, First Momentum Ventures and Verve Ventures.

Industry angels take part as well, among them Tilman Weide (formerly Linde Engineering), Christoph Zinsser (former Head of Project Finance at Stegra) and Marcelino Oreja (former CEO of Enagás). The capital goes into new commercial plants in Spain and further markets, lower production costs and a larger team.

Inside the honeycomb reactor

Instead of a fixed bed of loose pellets, the reactor is a metal body with many narrow channels, each coated with catalyst. Heat leaves through the metal quickly, so the plant can ramp up when wind and sun are plentiful and slow down when they are not.

From electricity and water to gas in the grid

Electrolysis

Renewable electricity splits water into hydrogen and oxygen. Plants sit next to wind and solar parks, so the power comes straight from the source.

Methanation

Biogenic CO2, for example from biogas plants, joins the green hydrogen in the honeycomb reactor and becomes methane.

Grid delivery

The gas is chemically identical to fossil natural gas. It travels through existing pipelines to factories, utilities and shipping without new equipment at the customer.

Miajadas, the first commercial plant

In Extremadura, TURN2X went from site selection to inauguration in under six months. Every cubic metre the plant produces is already sold through long-term offtake contracts.

“Energie 360° set the goal to fully switch to renewable energies by 2040. We see our collaboration with TURN2X as a promising option to achieve the transformation of the energy system from fossil based to renewable.”

Built by three friends from KIT

Philip Kessler, Benedikt Stolz and Dr. Dominik Schollenberger met at the Karlsruhe Institute of Technology, where Dominik spent more than a decade on methanation research. Today more than 20 people work on the mission from Munich's Werksviertel.
