Top 5 clean energy startups

2023 is on track to be the hottest year since records began, but it’s estimated that in the future, these temperatures will be classed as average. Change to put the planet back on track needs to happen, and it needs to happen fast.

In the mission for a greener and more sustainable world, innovative startups are emerging as the driving force behind the global clean energy revolution. Startups are rising to the challenge, presenting solutions that harness the power of renewable resources while reducing the carbon footprint of traditional energy sources.

In this article, we will shine a spotlight on five clean energy startups that are making a significant impact on the transition to a cleaner, more sustainable future. Join us as we delve into the breakthrough technologies of these pioneering clean energy startups.

Carbo Culture

Carbo Culture is a climate technology company building a rapidly scalable biochar carbon removal solution. Carbo Culture take waste biomass and transform it using its patented reactors, permanently storing the carbon in an inert, solid form called biochar. Its unique process produces high-quality biochar for agricultural and construction applications, generates renewable energy, and creates some of the most tangible carbon credits on the market.

Freyr Energy

Freyr Energy is a full-service solar company that offers a range of smart solar rooftops, pumps, petrol pumps, and micro grids. Freyr Energy was founded on the principles of making solar energy affordable and accessible for everyone. In order to make adoption of solar energy a reality at the grass-root level, the startup identified that consumer awareness, affordability and accessibility play an integral role. With its platform, SunPro+, its extensive channel-partner network and efficient service, Freyr Energy ensure that these three factors are addressed to make sure your venture into solar energy is hassle-free.

H2GO Power

H2GO Power is a cleantech startup. It develops and delivers hydrogen energy storage technology for zero-emission, safe and reliable power supply, with a range of commercial applications. Its mission is to deliver clean, accessible and reliable hydrogen energy from renewable sources that can meet decarbonisation targets fast, as well as bring profitable social impact to millions across the world. The vision of the startup is to create technologies that drive the transition to a more sustainable planet.

Liquid Wind

Liquid Wind is an electrofuel development company with a vision to reduce the world’s dependency on fossil fuel. The startup develops, finances, builds, and manages facilities to convert carbon dioxide emissions and green hydrogen into valuable, carbon neutral fuel.

Liquid Wind facilities produce green electrofuel (eMethanol), made from biogenic carbon dioxide and renewable electricity. The fuel can be produced at scale to meet the growing demand for fossil-free alternatives. The production process mimics the model of photosynthesis in green plants, which uses the energy of sunlight to split water into oxygen and hydrogen. Using the same principle, it splits water into oxygen and hydrogen, using renewable energy (wind, solar, hydropower, or other) in an electrolyser. The hydrogen that comes out from this process is combined with biogenic carbon dioxide that has been captured from industrial waste gases, purified, concentrated and transferred to the nearby facility to form eMethanol.

Next Energy Technologies

Next Energy Technologies is a startup on a mission to bring solar energy to the masses, by creating a coating for windows that generates solar power the same way panels do. NEXT’s transparent photovoltaic nano-coating cost-effectively transforms windows into electricity producing assets by converting UV & IR light into electricity, allowing buildings to produce on-site renewable energy.

Using a surface area like windows means these can have the potential to generate a significant share of renewable power. Not only that, but a criticism of traditional solar panels is that they’re unsightly, which is not the case with NEXT’s coating. The product also eliminates the space needed to be used with traditional panels, and can be utilised by more people and companies.
