Year Founded: 2020

Headquarters:  Barcelona, Spain

Total raised: $36.8 M

What they do: 011h utilizes timber, sustainable design methods, and software to rapidly construct affordable and eco-friendly homes. 

Scientific studies have shown that the built environment is responsible for 40% of yearly carbon emissions, encompassing both the energy used during a building’s operation and the emissions generated in the production of building materials. Consequently, sustainable housing is often associated with higher costs, impeding scalability and making the sector challenging to decarbonize. 

011h addresses this challenge comprehensively by uniting suppliers, builders, planners, and developers on a unified platform. This integrated approach streamlines the building process, reduces project management time, and enables the measurement of end-to-end embodied carbon in new constructions. Using several programs, they have reduced the time wasted on the design of the house. 

Notably, after designing, the program shows the approximate carbon footprint it’ll have by the end of the project. This positions 011h favorably, especially within the context of climate tech startups.

Redwood Materials

Year Founded: 2017

Headquarters:  Nevada, USA

Total raised: $1B

What they do: Redwood Materials, one of the top climate startups, is on a mission to build a circular supply chain that not only powers a sustainable world but also accelerates the reduction of fossil fuels. The company focuses on making batteries both sustainable and affordable by closing the loop at the end of their life cycle. 

Redwood is localizing a global battery supply chain, producing anode and cathode components in the U.S. for the first time, utilizing recycled batteries. It is creating a closed-loop, domestic supply chain for lithium-ion batteries, covering the collection, refurbishment, recycling, refining, and remanufacturing of sustainable battery materials. 

The team has also shared some of their predictions and goals. By 2025, Redwood plans to produce enough anode and cathode for one million electric vehicles annually, representing 100 GWh. 5 years later, the goal is to scale up production to provide enough anode and cathode for five million electric vehicles annually, amounting to 500 GWh.


Year Founded: 2013

Headquarters:  Berlin, Germany

Total raised: $200 M

What they do: At Infarm, the team is redefining the future of agriculture with its advanced farming system that prioritizes sustainability, efficiency, and environmental friendliness.

Impossible Foods

Year Founded: 2016

Headquarters:  California, USA

Total raised: $2 B

What they do: Who said that climate companies always have to deal with solar systems, technology, and solar panels? There are companies fighting climate change through the reduction of the usage of meat. 

One of the best examples of that kind of climate tech startups is Impossible Foods, which finds that animal agriculture uses lots of natural resources that could’ve been used in other spheres. 

Considering the fact that meat production requires approximately half of the land and is responsible for at least 15% of global greenhouse gas and 25% of the world’s freshwater, this company has decided to change the rules of the game by using a small amount of energy, water and land to “create” meat from plants. 

And so, firstly, the team behind Impossible Foods decided to produce a burger made of plants. Top scientists have been working on the idea of recreating meat, dairy, and fish using plants. This team’s mission is to transform the global food system in order to reduce carbon footprint.

Universal Hydrogen

Year Founded: 2020

Headquarters:  California, USA

Total raised: $82.5 M

What they do: It’s not a secret that the biggest climate tech companies mostly concentrate on the reduction of carbon footprint as nowadays it’s an immediate problem. 

Similar to many other climate tech startups, Universal Hydrogen has also focused on that problem yet in a very interesting way. It offers near-term, scalable, and true zero-carbon fuel for aviation. How is it possible? Easily! Hydrogen is made of water and consequently, its emission is only water which makes it safer than jet fuel. That makes hydrogen much safer. 

Not only the safety but also its affordability is a remarkable factor. Starting in 2025, this company’s product will have the same cost as jet fuel, with a decreasing tendency. It’s also more lightweight and contains 3 times as much energy per weight as jet fuel, ensuring longer flights and battery power. 

As for the airplanes, there’s no need to have additional infrastructure, because the team behind one of the top climate tech startups is working on the development of conversion kits to upgrade the current fleet with a hydrogen fuel cell system.
