Architects of sustainable growth

Change is only sustainable if we can make it profitable. Therefore, we focus our activities in the field of renewable energy systems directly on increasing cost efficiency.

In 2015, based on our technologies, we confidently predicted a decrease in Levelized Cost of Electricity (LCOE) by 50% within the next five years. In fact, renewables have slightly outperformed our prediction with Heraeus technologies contributing to one third of this necessary and highly welcome reduction.

LCOE-Reduction of Renewable System

Perfectly matched solutions for increasing efficiency requirements

New technologies are transforming the use of photovoltaics and increase efficiency:
exciting architecture and design modules help to energize our daily lives.

+20% Cost Efficiency within the next 5 years with Heraeus Photovoltaics solutions

In cities, solar panels will be invisible:

  • Roof elements with integrated high efficiency thin film.
  • Windows coated with transparent organic or inorganic thin film material.
  • Façades made of thin film modules in all colors. Classical panels invisibly integrated into construction materials.

Crystalline silicon will remain a component in most panels:

  • Near-term efficiency increases are achieved from PERC to PERC generation.
  • Mid-term efficiency increases will be achieved by back-contacted heterojunction or tandem modules.

Increasing the reliability of wind parks: a double impact on cost efficiency

Maintenance costs account for 70% of overall operating costs for offshore wind turbines.

1% Cost Efficiency within the next 5 years

Thermomechanical stress results in failures of electronic components which are a main cause for downtimes and maintenance cost.
Heraeus technologies significantly contribute to a reduction of these costs.

Heraeus technologies allow you to reduce maintenance costs and increase your annual energy output.

The Heraeus Die Top System is an electronic packaging system used among others in inverters. It reduces thermal stress and increases a module’s lifetime. By enabling the use of copper wire in combination with sinter technology, it significantly improves the electrical, thermal and reliability performance of die connections and positively affects the performance of the entire module:

  • Up to 20x higher module lifetime.
  • Higher temperature resistance allows for junction temperatures of e.g. 200°C.

Heraeus platinum sensors for temperature control optimize a wind turbine’s capacity and increase its reliability.

Our maintenance-free slip ring contacts for data transmission to the rotor blades further decrease operational costs.

More efficient catalysts for PEM Electrolysis

Generation of Hydrogen via PEM electrolysis from excess energy of renewables is the key factor to realize clean mobility and affordable energy storage.

10% Cost Efficiency within the next 5 years

Today, 95% of all hydrogen is produced from fossil resources. Renewables are the only clean alternative.

Generation of hydrogen via Polymer Eletrolyte Membrane (PEM) electrolysis from excess renewable energy is a key factor in making clean mobility and affordable energy storage a reality – if it can be competitive.

For clean hydrogen to be competitive, the overall efficiency of hydrogen generation via PEM electrolysis must be increased. With oxygen evolution reaction (OER) limiting overall performance, the efficiency of hydrogen generation with platinum-based cathode material strongly depends on the anode catalyst material.

Heraeus provides advanced anode catalysts to enhance system efficiency, helping to bring down costs:

  • Power conversion increased by 20%
  • Precious metal content reduced by a factor of 10
  • Production cost reduced by >50% per kg H2

Advanced storage solutions for new energy concepts

The realistic and sustainable success of renewables depends on advanced storage solutions which can bridge the natural fluctuations in renewable generation and demand.

20% Cost Efficiency within the next 5 years

Increased demand for renewable energy storage and grid balancing will have a number of consequences for the future energy market:

  • Battery costs will decrease by 20% year on year to 150 USD by 2020.
  • Battery farms and batteries in every building will be an integral part of power generation.
  • Vehicles will form a massive electricity storage cloud.

Regardless of the rise of lithium-ion batteries and supercapacitors, advanced lead-acid batteries will have by far the biggest impact on cleaner mobility within the next 20 years. Growth in electro-mobility, electricity storage and decentralized storage systems for renewable energies demands flexible storage capacities, such as lithium-ion batteries or supercapacitors that can satisfy these requirements.

Heraeus has developed Porocarb® , an additive which enhances ion transportation in your batteries. With Porocarb® , Heraeus offers a solution not only for emerging battery technologies but also for widely-used lead-acid batteries:

  • up to +20% higher energy density
  • up to +50% higher rate capability
  • improved cycle life
  • uncompromised safety

Renewable Energies - a smart job motor

Renewable Energies will create new, high value and cleaner jobs.

Millions of new smart jobs

Universities curriculums

  • Renewable Energies integration will be mandatory for architecture, construction engineering and design.

Architects rethink

  • Architects will construct power plants when they design any building. Only power generating facades will be available.

New enhanced jobs develop

  • e.g. integration of facade builder, roofer and electrician in line with China 2025, also for craftsmen.
