Zenco Group Information

Zenco Group is a UK-headquartered renewable energy and infrastructure developer. We produce defossilised energy, fuels and chemicals from sustainable marine feedstock: grown, not extracted. Europe’s targets for renewable gas and fuels are fixed by law. What’s missing is enough reliable feedstock to meet them. Zenco produces a reliable, consistent, high quality feedstock at sea: with no farmland, no freshwater and no competition with food crops. Offshore seaweed cultivation are bio-remediation projects, aimed at restoring dead sea zone by removing run-off, reoxygenation of the marine area, and recovery of local ecosystem. Harvested biomass is converted intoa standardised pellet feedstock for AD, with predictable yields and chemical advantages. Zenco's products are Drop-In: they they run through the existing infrastructure - grids, pipelines, plants and refineries society already depends on: • Biomethane: through Anaerobic Digestion plants, into the gas grid • Renewable transport fuels: biocrude refined anywhere to a range of bio-fuel alternatives • Bio-chemicals and -fertiliser from digestate: keeping the value chain circular Zenco's flagship, Project Keystone, links offshore seaweed cultivation in Spain with a large-scale bioenergy facility planned at the Humber Freeport in the UK. For this site, we combine innovation with proven partners: Under our 400 GWh/yr offtake with SmartestEnergy (Marubeni group), we focus on producing the energy while they handle the route to market, trading and optimisation, drawing on decades of experience. Our team brings together marine science, oil and gas operations, infrastructure delivery, institutional finance and energy regulation: the skills a first-of-a-kind project needs. In 2026, we were selected for the Blue Earth Summit’s BE100. Grown. Not extracted.
