Renewable energy is a fast growing sector where production and treatment processes are constantly improving. Changes in unit capacities and processes result in new challenges for operators, energy companies and plant designers. Howden have a complete set of solutions for every situation, and experience in gas handling solutions. Our solutions integrate renewable energy production, treatment, distribution and conversion units. Our blowers gather landfill gases for collection and transfer to treatment units. Our fans, blowers or screw compressor collect biogas generated in anaerobic digesters. Howden heaters, draught fans and air fans are used to increase efficiency of biomass, wood and waste boilers. Screw compressor feed biogas treatment units while bio-methane screw compressors deliver gas to the grid or gas turbines to the appropriate pressure. Howden fans extract residual gases from process capacities and ensure buildings ventilation and aeration. Cooling fans are used in HVAC and for refrigeration applications The amount of renewable energy generated from solar, wind, geothermal, hydropower can be higher than the quantity required by the grid therefore off grid electricity is converted to hydrogen via electrolysers. Our compression solutions cover Power to gas applications, like H2 high pressure capacity filling for distribution and dispensing solutions mainly for mobility projects. In dispensing stations for Fuel Cell Vehicles (FCV) and Heavy Mobility Equipments HME, compressors deliver high to very high pressures to fill vehicle tanks. H2 is transported and distributed to industries or used as clean fuel.
Howden owns a set of fluid handling technologies covering ventilation, compression and heat transfer. Howden brought solutions to many specific challenge met in renewable industry processes
Every project has different specific needs and operating conditions. Our ability to deliver custom-design solutions is extremely valuable. Whether supplied as a stand-alone unit or a complete package, our productss are designed to match the rigors of its environment as well as its specific task, and engineered to offer continuous uninterrupted operations.
Howden engineering teams and field engineers have access to our 160 years of learning, meaning we can offer our expertise at every step of the process from product selection to ongoing support. Our world organisation provide local responsive support to end users and customers.
Direct Heat and Power CHP : Electricity-Fuel gas. In site power plant equipments compress the feed gas for the turbines to the appropriate pressure.
Gas contains methane and carbon dioxide. Landfill gas is collected and sent to the gas treatment unit.
If biomethane is being fed to grid there may be a requirement for a biomethane compressor
BioMethane Compressed gas – vehicle fuel & distribution.
The biogas is first compressed, then cooled and desulphurized. A large plant may have 2 stages of biogas compression (up to 3 units – up to 11 bar).
Typically there will be 2 biogas compressors feeding the absorption column. If biomethane is being fed to grid there may be a requirement for a biomethane compressor
Membrane separation 1 or 2 compressor according to capacity
H2 Compressors for process
H2 is injected in city gas network. Pipeline injection compressors.
Residual fuel cells

H2 tank compressor. Fuel cells
Exhaust air
Shorebased wave systems (Wells turbines)
Forced draught fans move ambient air at low pressure through the air preheater to provide heated oxygen for the combustion process.
Induced draught fans are vital in maintaining furnace pressure at just below atmospheric pressure. They draw the flue gases out of the boiler into the air preheater.
Primary air fans are used to move air through the air preheater in coal and biomass fuelled stations. The size and configuration of the fan depends on the temperature of the primary air.
Secondary air fans feed into the boiler combustion chamber at a higher point than the primary air to promote more complete combustion.
