A few years of significant disruption in the energy sector: 2025 Energy is a hot topic at the moment, as the world shifts to clean and sustainable energy methods, new startups are popping up with innovative ways to improve how we produce, store and use energy. In the process, these startups are fighting climate change and building a more sustainable and greener future.
Here's a deep dive into some of the top emerging global startups in the energy domain that are making waves this year.
Rondo Energy (USA)
Rondo Energy: Tackling One of the Most Boring and Yet Critical Problems in Renewable Energy. Their finished product, the "Rondo Heat Battery," converts excess renewable electricity into heat and stores it inside bricks. Subsequently, such heat can be utilised in various industries, primarily cement, glass and steel.
Why it's important:
The use of industrial heaters generates a lot of carbon. Its technology is helping to cut emissions cleanly and affordably.
Electric Hydrogen (USA)
Electric Hydrogen backs the company. These state-of-the-art electrolysers utilise water, but only renewable energy is consumed to produce Hydrogen and oxygen. Using this green Hydrogen, we can fuel industries, heavy transport, and ships.
Why it's important:
Hydrogen is the energy carrier of the future. This startup is working to scale it across the globe.
Octopus Energy (UK)
While it may seem like another power provider, Octopus Energy is a technology company. They apply AI and intelligent systems to manage energy supplies and their demand. Therefore, their customers receive immediate savings on the cost and a dramatic reduction in environmental impacts through using cleaner energy.
Why it's important:
Its tech-first approach is not only saving consumers money but also lowering carbon footprints across the board.
Sunfire (Germany)
Sunfire is working on high-temperature electrolysis and fuel cell systems. The approaches of these companies result in green Hydrogen and e-fuels (synthetic fuels made with renewable energy), respectively. Specifically, these fuels encode for the dense energy of traditional petrol and diesel in hard-to-electrify sectors.
Why it's important:
Sunfire provides cleaner fuel options for the heavy industries and transportation sector.
Solugen (USA)
Solugen replaced oil-based chemicals with those made from renewable plant materials. Bio-based production is derived from their enzymes and through renewable energy, which means a cleaner way of making industrial products.
Why it's important:
It diminishes the pollution from traditional chemical small production, one of the biggest carbon emitters.
EcoFlow (China)
EcoFlow is a rapidly growing startup that makes portable batteries and solar-powered home backup systems. They produce products for camping, emergencies, and off-grid living.
Why it's important:
Providing easier access to clean energy for people, places and small businesses globally.
Amogy (USA)
Amogy will be the first company to make ammonia as a future clean energy gas. Ammonia is also much easier to transport and store than Hydrogen, while Amogy has developed a system that can provide zero-emissions power for engines and ships.
Why it's important:
Namely, they solve a significant problem in the clean energy realm by allowing more efficient storage and transport of energy.
Gravitricity (UK)
Centralised energy storage and balancing response company Gravitricity is developing a gravity-based energy storage system. Massive weights are raised and lowered using electricity, acting as a super-sized battery (without chemicals).
Why it's important:
This is a clever and green way to stock up electricity for longer terms, particularly in old mine shafts.
Final Thoughts
Startlift, Cipharryhk: Ideas against Climate Change startups are examples of the many projects in Search of Innovation for Clean Energy. Including hydrogen and heat storage, smart grids, and sustainable fuels — all of which serve a purpose when transitioning into the global energy landscape.
By 2025, these rising startups are poised to meet the clean and renewable energy demand with creative solutions prioritising sustainability.
Watch them — the energy revolution is here!
