Biogas plants for project developers

A technology partner for biogas project development. HoSt Bioenergy Systems delivers turn-key EPC biogas plants with in-house upgrading and CO2 liquefaction, from feasibility to commissioning.

A technology partner from feasibility to commissioning

Project developers carry the risk of feedstock, technology, permitting and delivery in a single business case. HoSt works as the technology partner that de-risks the build: a global technology leader with more than 450 renewable energy projects delivered, offering the full biogas plant in one place. HoSt is currently building Lorca Bioenergy in Spain for developer Five Bioenergy, one of the largest biogas plants in the country. See our projects for the wider track record.

De-risking the business case

Before design, HoSt models the mass and energy balance and the carbon intensity (CI) score, and advises on feedstock configuration and offtake. This gives a developer the numbers behind the Total Cost of Ownership and the revenue case.
HoSt guarantees 95% availability and often reaches 98 to 99%, backed by 24/7 service and remote monitoring. Predictable uptime supports the financing model.
At Lorca, HoSt cools the digestate through external heat exchangers for the warm climate and recovers osmotic water from thin-fraction treatment to reuse in the process, avoiding scarce fresh water. Complex site conditions are solved in the design.

What we delivers to project developers

  1. Turn-key EPC or a flexible scope
    HoSt delivers a complete plant under a full EPC contract, or a reduced scope of design and key components where a developer wants to lead parts of the build. The contracting model flexes to the project.
  2. A full in-house technology portfolio
    Anaerobic digestion, biogas upgrading, CO2 liquefaction and bio-LNG come from one supplier. One-stop delivery removes interface risk between vendors and lets a developer sell biomethane, food-grade bio-CO2 and biofertiliser from a single site.
  3.  Feedstock flexibility and process stability
    HoSt engineers the feeding, mixing and digester design around the specific feedstock mix, including difficult and varied streams. Stable digestion protects the yield the business case depends on.

Frequently asked questions

What does the build process of a biogas plant look like?

It runs in clear phases: feasibility and FEED study, engineering, permitting, construction, and commissioning through to handover. HoSt can take the full turnkey EPC scope or a reduced package of design and key components, depending on how much you keep in house. More information.

How long does it take to build and commission a plant?

Timelines depend on scale, permitting and site conditions rather than one fixed figure, with permitting often the longest and least predictable phase. Early feasibility work and a structured engineering process keep the schedule realistic. More information.

What site and infrastructure does a plant need?

A plant needs space for digesters and feedstock handling, a secure feedstock supply, and a route to market for the energy: a grid connection, a heat user, or a gas or CO2 offtake. Assessing these early is central to a bankable project. More information. 

What subsidies and incentives can support a project?

Support varies by country and includes feed-in schemes, renewable gas certificates, blending obligations and transport fuel credits, which together shape project economics. Because the framework differs per market and changes over time, we assess the applicable incentives during feasibility. More information. 

What types of biogas plant can you build?

From farm-scale manure digesters to large organic-waste and industrial plants, with optional upgrading, bio-LNG, bio-CNG and CO2 liquefaction. The right configuration follows from the feedstock, the offtake and the site, which is where the configurator and feasibility work come in. More information.
