Renewables and power to gas


Howden products and services offer the best long-term value across a wide range of renewable sector applications, ensuring consistent, safe and efficient site output

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.

Comprehensive, Customized Services

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

    • Centrifugal Fans
  • Forced draught fans


    Forced draught fans move ambient air at low pressure through the air preheater to provide heated oxygen for the combustion process.


    • Fans
  • Induced draught fans


    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.


    • Fans
  • Primary air fans


    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.


    • Fans
  • Secondary air fans


    Secondary air fans feed into the boiler combustion chamber at a higher point than the primary air to promote more complete combustion.
