Hydrogen, Wind & Storage: The Biggest Energy Top 10s in 2025
From the world's biggest hydrogen producers to the companies producing the most wind power, Energy Digital kept on track of who was on top of the industry throughout 2025.
Each of these lists was carefully curated by the team to rank by everything from capacity to influence.
To bring the year to a close, Energy Digital has ranked 10 of the top lists created in 2025.

Before the year 2030, more than half of the world’s electricity will come from low-emission sources according to the IEA.
A lot of progress has been made – a boom in solar and wind energy projects pushed the world past 40% clean energy used in 2024 according to think-tank Ember.
Carbon dioxide emissions, however, have risen to an all time high with hot weather pushing up overall demand for power.
To combat this, renewable energy has to start replacing fossil fuels – not just adding to the supply.
Around the world, enormous and ambitious renewable energy projects are operational and under construction.
Energy Digital ranked 10 of the largest renewable energy projects in the world.
19 February 2025
Energy technology platforms are essential to energy management across a broad range of industries.
Formed of interconnected digital systems, these platforms are part of an industry-wide move from traditional energy infrastructure models — focusing on integration, adaptability and resilience rather than isolated energy projects.
Energy Digital ranked some of the industry’s most innovative and cutting-edge energy technology platforms — as well as what sets them apart from others on the market.

Digital technologies are everywhere, from roads and street lights to smart meters and grids.
Urban areas account for more than two thirds of global energy consumption according to the European Commission.
Making cities smarter is not only benefitting the lives of those living in them, but also helping to simplify energy demand and meet sustainability targets.
Energy Digital ranked 10 of the top smart cities in the world.
5 March 2025
Building energy management systems (BEMS) monitor and control a building’s energy use.
The solution is a key component of a smart building technology as it acts as the building’s brains.
BEMS can be responsible for functions including managing HVAC and lighting based on real-time data — ultimately contributing to increased efficiency and sustainability in a smart building environment.

Ambitious government policies, technical advancements and increasing investor confidence are pushing wind energy to new heights around the world.
Wind farm projects are taking shape both onshore and offshore all over the world.
These projects are being scaled up to unprecedented sizes, pushing the boundaries of renewable energy technologies.
Wind farms are no longer just about generating power – creating jobs, stimulating local economies and fostering a sustainable future are just some of their benefits.
Energy Digital ranked 10 of the top wind energy projects around the world.
29 April 2025
Electrification, integrating renewables and making grids more reliable are all things the world needs.
However, these can’t happen without an increase in energy storage.
Battery storage in the power sector was the fastest growing energy technology commercially available in 2023 according to the IEA.
The demand for energy storage can only continue to grow, and a variety of technologies are being used on different scales.
Energy Digital ranked 10 of the top energy storage technologies.
16 April 2025
Energy underpins nearly every aspect of modern life, and demand for it is growing.
A lack of visibility, unreliable data collection and unnecessary energy waste are all making this growth a challenge.
Energy management platforms can help, offering automation, visibility and a central point for data.
With energy demand expected to grow as much as 18% by 2050 according to McKinsey research, it is time for businesses to get on top of where their energy is going.
Energy Digital ranked 10 of the top energy management platforms.
1 October 2025
Energy consulting companies are facilitating the energy transition by providing expert guidance to businesses in managing and optimising energy use, which is crucial for cost reduction, regulatory compliance and sustainability.
These consultants aim to help organisations navigate complex and evolving energy regulations, promoting adherence to policies that reduce carbon footprints and boost renewable energy adoption.
The transition can be facilitated through consultants evaluating, planning and implementing projects such as solar and wind, balancing initial investments with long-term benefits.
9 July 2025
Wind power has grown substantially and is hoped to provide a significant portion of the world’s energy by 2050.
This clean source produces electricity without emitting greenhouse gases or pollutants and harnesses natural resources that will not run out.
To achieve global decarbonisation goals in time, the International Energy Agency says annual wind capacity additions need to increase from around 115 GW in 2023 to 340 GW in 2030.
Energy Digital ranked 10 of the top wind power companies supporting wind development around the world.
2 July 2025
Hydrogen is a highly versatile and clean energy carrier that is set to play an important role in the energy transition.
In sectors that are difficult to electrify, like heavy industry or transport, it can be used as a fuel that only emits water vapour with no CO₂.
While it holds a lot of promise, infrastructure and technologies still need progress for hydrogen to be viable as a lever for decarbonisation.
Across the world, companies are making progress in developing hydrogen and setting up a hydrogen economy.
Energy Digital ranked 10 of the top hydrogen companies by market cap.
