Green Energy solutions for sustainable energy storage

Energy storage plays a crucial role in the integration of renewable energy by capturing excess generation and releasing it when needed. The production of green hydrogen through renewable energy-powered electrolysis is also a critical element of sustainability, in contrast to the emissions-intensive gray hydrogen, produced by fossil fuel sources. The widespread adoption of green hydrogen energy is essential to move away from reliance on fossil fuels and accelerate the transition to a more environmentally responsible energy future. However, without reliable green energy solutions to capture and retain excess renewable generation, the intermittency of adequate sunshine and wind can disrupt grid stability and clean energy supply.

Powering a sustainable future with MANN+HUMMEL's green energy solutions

MANN+HUMMEL's energy storage and green hydrogen solutions are instrumental in advancing renewable energy technologies. By integrating our high-performance components, customers invest in systems that drive sustainability and energy efficiency, helping to shape a more environmentally responsible future.

Energy Storage

The energy transition from fossil fuels to renewable sources, such as wind and solar, requires reliable energy storage solutions. This is due to the intermittent nature of renewable energy - the sun doesn't always shine and the wind doesn't always blow. Flow batteries, with their scalability and longevity, are uniquely positioned to fill this gap.

Electrolysis Green Hydrogen

Green hydrogen is produced using renewable energy sources, such as wind or solar power, to electrolyze water, separating it into hydrogen and oxygen. This process is carbon-neutral, distinguishing green hydrogen from other hydrogen types produced using fossil fuels. Its production aligns with the goals of the energy transition, striving to reduce carbon emissions and combat climate change.

Why choose MANN+HUMMEL Water & Membrane Solutions?

  • Consistently reliable system health and exceptional electrochemical performance

  • Best-in-class product match and performance to system requirements

  • Lower TCO (total cost of ownership) with our unrivaled desalination and RO membrane technologies

In addition to its energy storage and green hydrogen offerings, MANN+HUMMEL also provides a wide range of complementary solutions, including ion exchange membranes, ultrapure water systems, demineralized water technologies, and desalination systems.
