Energy Landscape Model: Sector coupling with green hydrogen

To reach the target of net zero CO2 emissions by mid-century, the power, industry and mobility sectors have to be coupled in order to provide renewable energy to support their decarbonization. Green hydrogen is the technological answer for sector coupling.       

Offshore Power 

  • Renewable power from wind can be produced onshore or offshore.  
  • Offshore wind power far from the coast allows stable power supply and higher acceptance in society.
  • Additional costs for grid connection and power transmission to shore must be considered. 

Power Transmission

  • Power generated from renewable sources must be transmitted over long distances to load centers. 
  • An increasing share of fluctuating renewables requires measures to increase grid stability.  
  • We offer the entire portfolio of high-voltage products and systems including the Blue Portfolio.

Electrolysis

  • This innovative electrolysis system is based on the proton exchange membrane (PEM) technology. 
  • PEM technology is ideal for working with fluctuating renewable sources, as it enables a highly dynamic operation.
  • It delivers pure H2 and oxygen of the highest quality. Low maintenance and a compact design are further benefits.

Storage

  • The need for storage increases with the share of renewable energies such as solar and wind in the energy mix.
  • Green hydrogen plays a key role as an energy carrier and as long-term storage medium.   
  • Suitable infrastructures for large-scale storage include gas grids with enormous storage potential.

Re-electrification

  • Re-electrification is done either by combustion, e.g., in a gas turbine or reciprocating engine, or in fuel cells. 
  • It can be combined with battery energy storage (BES) in a hybrid generation unit to increase flexibility.
  • We offer fuel systems, combined heat and power plants, reciprocating engines, fuel cells with partners, BES, and grid connections.

Decarbonization of Industry

  • Worldwide, ~70-80 million tons of hydrogen are produced annually from natural gas with CO2 emissions.
  • H2 is used in various industries, such as the steel industry as well as the food industry.
  • In comparison, the production of green H2 by electrolysis of water with renewable energy is free of CO2 emissions.

Hydrogen Transport

  • H2 offers a transport energy density comparable to natural gas and thus provides the capacities of climate-neutral energy on the market.
  • Regarding e-Fuels, existing infrastructures can be used for fuel transport, storage and fueling.
  • For transportation by ships, they can even be fueled with e-Methanol.

Hydrogen Compressors

  • An essential component of the hydrogen value chain is compression
  • It is the enabling technology for safe and cost-effective transport, storage and use of hydrogen
  • From the point at which hydrogen is produced to the point where it is consumed, different types of compression (e.g. Reciprocating Compressors or Turbocompressors) are required
