Storing Power

Renewable energy solutions such as solar and wind power are more accessible and more cost effective than ever before, but challenges remain. What happens when the sun goes down and the wind stops blowing? How do you store all the excess power that’s been created?

Storage technologies pave the way for a renewable-powered future

Low-cost cleaner energy is altering conventional power generation models. As it reaches higher penetration levels in front of and behind the meter, it’s even altering the grid itself. Solar and wind power give power generators and consumers an affordable new option for producing and purchasing electricity, but also create new challenges. To match demand with intermittent supply, utility-scale energy storage remains a critical part of the flexibility puzzle.

The next generation of end-to-end renewable energy solutions is paving the way to abundant and affordable renewable energy storage. This storage enables a path to a decarbonized power grid by shifting renewable energy use a few hours, days, weeks or even seasons.

At Mitsubishi Power, our mission is to provide power generation and storage solutions that will empower you to combat climate change and advance human prosperity. Our hydrogen strategy is about enabling you to succeed in the next phase of decarbonization by providing solutions for a change in power.

Evolving Short-Duration Storage

Battery power storage systems are emerging as one of the solutions to increase system flexibility. As the global power sector experiences dramatic changes in power generation, lithium-ion batteries are great for intra-day storage and small-scale variations. With decades of experience creating power storage systems, Mitsubishi Power offers lithium-ion battery solutions either as an individual product or as part of a larger integrated energy solution.

Achieving Long-Duration Power Storage with Green Hydrogen

The potential of green hydrogen is inextricably linked with renewable resources such as wind and solar. During high generation periods, the excess electricity they create can power electrolysis equipment to produce green hydrogen. However, if the sun isn’t shining and the wind isn’t blowing, these energy sources need a backup to avoid an interruption of power. That’s where stored green hydrogen comes in. It can be mixed in increasing proportions with natural gas for power generation with reduced carbon emissions, up to 100% green hydrogen for zero carbon emissions.
