Biogas Utilisation
There are multiple options for gas use:
- Combined Heat & Power (CHP)
- Heat
- Biogas
- Bio-methane
- Other
Option 1 – CHP:
- Most used for large scale digestion
- Production of electricity and process heat – Heat for own use
- Electricity partly for own use, partly sold
- For small scale heat valorisation is difficult
- Electricity feed-in is subsidised money
Pros:
- Simple technique
- Proven technology
- Easy offset of energy
- Heat for free on farm
Cons:
- Only electricity
- If electricity price drops, BC drops
- Difficult heat valorisation
- Low energy efficiency
Option 2 – Heat:
Heat production by boilers or CHP Heat delivery to:
- On farm processes
- District heating
- Industry
- Swimming pool, etc
Option 3 – Biogas:
Direct sales of (un-treated) biogas Transport via:
- Biogas grid
- Biogas tank transport
Delivery to:
- Industry
- Swimming pools
- District heating
In most countries biogas sales not subsidized:
- Option with satellite CHP
- Selling of the heat
- Lobby for subsidy scheme for raw biogas
Pros:
- No upgrading needed
- No CHP needed
- Proven technology
- High energy efficiency
- Low maintenance costs
- Possible at longer distances
Cons:
- Biogas often not subsidized
- Depended of end user(s)
- New infrastructure needed
Option 4 – Bio-methan:
Sales of bio methane as:
Natural gas substitute
- Grid injection
Transport fuel
- Feed-in in natural gas grid
- Selling via tank station
- Off set with tank transport
Frequently Asked Questions
What is Biogas Utilisation and how does it work?
Biogas Utilisation is an engineered water or wastewater treatment process selected to achieve a defined quality, recovery or discharge objective. Its operating principle and treatment stages depend on the application.
What contaminants or water-quality problems can Biogas Utilisation address?
Performance depends on the selected configuration. Water analysis is used to identify suspended solids, dissolved salts, hardness, oil, organics, nutrients, metals or other parameters that the treatment train must control.
How is a Biogas Utilisation system designed and sized?
Design uses flow and load profiles, laboratory analysis, target outlet quality, recovery, operating hours, redundancy, footprint, utilities, sludge or concentrate handling and lifecycle cost.
How much does Biogas Utilisation cost in Singapore?
Cost depends on capacity, feed quality, materials, automation, civil and installation scope, performance requirements and ongoing consumables. A site-specific assessment is needed for a reliable budget.
Can World Technologies upgrade or maintain Biogas Utilisation?
Yes. World Technologies can review existing performance and support suitable upgrades, equipment replacement, commissioning, troubleshooting, consumables and preventive maintenance.
