Top 4 Renewable Energy Startups to Keep an Eye On

In the US, using fossil fuels for energy resulted in 73% of all GHG emissions and 92% of all human-caused CO2 emissions in 2020.
This is why we must constantly be on the lookout for new concepts and promote the development of renewable energy companies that can change the game.
After all, the transition to renewable energy will depend heavily on businesses that provide energy technology or egovernment software solutions.
The physics behind renewable energy is frequently rather similar, but the types of projects vary widely from one technology to the next and from one economic model to another.
The size and shape of startups in the renewable energy sector vary; some focus on developing novel solar and wind energy technology, while others are more interested in assisting in the planning and funding of such initiatives.
To take advantage of the local climate, other renewable energy firms develop efficient, ecologically friendly grid batteries or investigate the possibility of microgrids.
Let’s take a closer look at the selection criteria we utilized before we look at the best renewable energy firms.

You should pay attention to the following firms using renewable energy:


Chris Bale, the CEO of responsAbility Renewable Energy Holding, is located in Nairobi and oversees the co-financing and co-development of renewable energy projects throughout sub-Saharan Africa.
According to a market gap that responsAbility identified, most large businesses support sizable energy projects while small and medium-sized business owners are left out in the cold.
Furthermore, it is now even clearer that Sub-Saharan Africa has a growing need for affordable energy because of the COVID-19 pandemic.

Technologies from Proton

Although hydrogen manufacturing does not contain carbon, the fuel itself does. By utilizing cutting-edge technology that preserves carbon in the environment while producing hydrogen, Proton Technologies seeks to change that. Proton Technologies is one of the world’s top producers of renewable energy since they are almost done making the process of extracting hydrogen fuel emission-free.
Ian Gates and Jingyi Wang created this Canadian company providing energy technology solutions in 2015 in Calgary.
The cheapest and greenest way to extract clean hydrogen is from Proton, so Clear Hydrogen UK recently bought a license to use their technology to produce 5,000,000 kg of hydrogen daily.

Celtic Renewables

Let’s head to Scotland to start our list of businesspeople in the renewable energy sector. Their scotch whiskey is well known, but what about draff and pot ale, which are made using the same method as scotch whisky?
The biotech company Celtic Renewables in Edinburgh uses these waste products to produce renewable energy from sustainable ethanol and renewable chemicals. Low-carbon technology will eventually replace traditional fossil fuels.
Martin Tangney, who established the Biofuel Research Center at Edinburgh Napier University in 2007, started this business in 2011.
Biobutanol, a biofuel, is produced using the Acetone-Butanol-Ethanol (ABE) process, which uses bacterial fermentation.


The performance of photovoltaic modules is hampered by soiling, which is one of the key issues with solar energy.
If a solar plant is not properly maintained, dirt and dust deposits accumulate over the surface that absorbs the sun’s light, resulting in an average energy loss of between 3% and 45%.
In 2016, Camilo Flores and Camilo Contreras, former classmates, founded INTI-TECH in Chile. It’s intriguing how they approached the issue in a novel manner that effectively handles the loss of efficiency in photovoltaic systems and provides an alternative to cleaning techniques that consume many resources.
A solar system can now be operated and maintained more efficiently and affordably thanks to a development from INTI-TECH.
To achieve this, cleaners that are less labor- and water-intensive than conventional cleaning techniques are used to clean solar farms.
Depending on the size of the plant, these cleaners can be either fully autonomous or semi-autonomous.


As startups look for ways to increase operational effectiveness, teams of experts combine any available renewable energy to give the locals clean, zero-emission electricity. People concerned with sustainability work to supply off-grid areas with critical power.
Businesses utilize clean and sustainable energy to combat climate change and adhere to environmental regulations. Making renewable energy cost-competitive with fossil fuels is the challenge. While economies of scale address the cost issue, technologies like automation, blockchain, and machine learning increase the effectiveness of operations and maintenance.
