Technology

One electrified platform, two applications.

Hyperion is a fully electrified solvent-based technology. The same core process captures CO₂ from industrial flue gas and upgrades raw biogas to grid-quality biomethane — engineered, piloted, and delivered as complete plants rather than a solvent alone.

Hyperion

Post-combustion CO₂ capture

Post-combustion capture removes CO₂ from flue gas after combustion, so it can be applied to existing emitters without redesigning the plant behind it. Hyperion targets hard-to-abate, point-source emitters.

Waste-to-energyCementPowerRefining & chemicals
Hyperion post-combustion CO₂ capture — process flow Animated schematic. Flue gas enters the direct contact cooler (DCC) for SO₂ removal, cooled by a recirculating cooling-water loop with a bleed. In the absorber a solvent captures CO₂ and treated gas leaves the top. CO₂-rich solvent passes through a cross heat exchanger to the stripper, where a steam-driven reboiler regenerates the solvent. Released CO₂ vapour is condensed to an approximately 98 percent by weight CO₂ product, with condensate returned to the stripper; lean solvent is cooled and returned to the absorber.

Why Hyperion

Fully electrified

The process runs on electricity and can operate in hybrid mode where waste heat is available. It needs no dedicated CHP unit, avoiding fossil-fuel dependency and the extra CO₂ that comes with it.

A better solvent

The Hyperion solvent is less toxic and more user-friendly than conventional amines, degrades less over time, and offers higher CO₂ capacity. Formulations are tuned to each gas input.

Lower energy demand

Overall process energy is reduced, with solvent regeneration at 100–110 °C versus roughly 120 °C for conventional amines.

Smaller footprint, lower CAPEX

A more compact plant means a smaller site footprint and lower capital cost.

High capture rates

Capture rates above 98% are achievable, with high-purity CO₂ product suitable for utilisation or storage.

Biogas upgrading

The same electrified process, extended to upgrade biogas to grid-quality biomethane.

The bigger picture

Hyperion-Bio upgrades biogas into grid-quality biomethane for homes, industry, and transport, while capturing the biogenic CO₂ for geological storage or use. Because that CO₂ is biogenic, storing it removes carbon from the atmosphere — turning organic waste into renewable energy and negative emissions.

Biogas value chain — biomethane and Bio-CCS with Hyperion Bio Organic waste feeds an anaerobic digester that produces biogas. Hyperion Bio upgrades the biogas into renewable biomethane, delivered to the gas grid for homes, industry and transport, while the separated biogenic CO₂ (Bio-CO₂) is sent to geological storage (Bio-CCS) or utilisation — delivering renewable energy and carbon removal.

The process

Unlocking biomethane's potential — a high-efficiency, low-energy process with near-zero methane slip.

Hyperion-Bio biogas upgrading — process flow Animated schematic. Biogas enters the absorber where a solvent captures CO₂ and biomethane leaves the top as product. CO₂-rich solvent passes through a cross heat exchanger to the stripper, where a steam-driven reboiler regenerates the solvent. Released CO₂ is condensed to a Bio-CO₂ product, with condensate returned to the stripper; lean solvent is cooled and returned to the absorber.

Why Hyperion-Bio

Higher-purity biomethane

Delivers biomethane at greater than 97.5% CH₄ purity.

Very low methane slip

Methane slip below 0.06% — around two orders of magnitude lower than membranes and PSA.

Robust to contaminants

High tolerance to common biogas contaminants and process upsets, such as oil-droplet carryover.

Carbon-credit revenue

When the captured CO₂ is stored, its biogenic origin makes it a negative emission — an additional revenue stream from carbon credits.

Reduced energy and CAPEX

Improved process economics unlocking biomethane potential.

Solvent-agnostic

Open solvents, when the site calls for it.

Hyperion isn't the only path. Where a project is better served by an established open solvent, we design and deliver capture plants on MEA, CESAR1, or aMDEA — with the same modelling, piloting, and engineering depth we bring to our own technology. The right solvent is always site-specific.

What drives the choice
  • Waste-heat availability
  • Chemical preferences
  • Site and regulatory constraints
From lab to plant

We deliver plants, not just a solvent.

Every stage — from the first model to a commissioned plant — sits under one roof, so the technology is de-risked before it scales.
