The operation has been led by Capital Sum through its Climate Tech SC Net Zero Ventures fund, with the participation of Shell Ventures and from the investor already present in the company Cemex Ventures.
WtEnergy transforms non-recyclable waste and biomass into renewable syngas, a gas that directly replaces fossil fuels in energy-intensive thermal processes, especially in sectors such as cement, paper, chemicals, and ceramics. Its modular plants, with capacities between 5 and 50 MW, They are integrated into the industrial facilities themselves, reducing energy costs, CO₂ emissions and dependence on imported fuels.
The technology is already operating on an industrial scale, with projects that cover up to 90–95 % of the thermal demand of the production processes, allow reductions of tens of thousands of tons of CO₂ per year and generate energy savings equivalent to more than 100 GWh of natural gas per year in certain facilities.
Furthermore, when clean biomass is used, the process produces biochar, a carbon-rich material with agronomic and industrial applications that contributes to permanent carbon sequestration. At the same time, the company is making progress in the upgrading of the syngas toward renewable hydrogen, methanol and synthetic fuels, expanding the climate and economic impact of their solutions.
With this investment, WtEnergy will execute its ongoing project portfolio, standardize its technological solutions and accelerate their implementation in key sectors for industrial decarbonization in Spain and Europe, consolidating the energy recovery of waste as a competitive path towards a low-carbon industry.
