The Climate Tech Startups to Watch This Month: September Week 3

September Week 3, 2023: In this monthly series, we highlight 5 climate tech startups to watch by featuring the incredible startups, companies, or projects that are leading the fight against the climate crisis. 

Each month, we add these startups to our running list, which we have categorized based on fuel emission sector data from the most detailed, recent data SBC could identify from the World Resource Institute in 2016.

This initiative from Startup Basecamp aims to support founders by giving them access to networking and exposure opportunities that help them to scale and finance their climate tech solutions.

Do not hesitate to join our collective movement by requesting your membership.

With care,
Guillaume and the SBC TEAM

Energy use in Industry and Buildings

1. HyperHeat GmbH


Founded: 2023 – Offenburg, Baden-Wüttemberg, Germany

Founders  & Leadership team: Lars Amsbeck & Frederick Lessmann

Elevator Pitch: Hyperheat is on a mission to enable the world’s most energy-intensive industries to reach zero carbon emissions at large scale, low cost and in the time to stop climate change.

Problem they solve: How to achieve precise high controlled temperatures for industrial processes whilst achieving carbon emission targets.

Impact: Process heat up to 1,950°C to run energy intensive processes like cement burning, steel & glass melting and basic chemical production.
All Electric: Using renewable electricity instead of burning fossil fuels – allowing for grid balancing demand in combination with inexpensive thermal storage.

2. Hide Biotech


Founded: 2019 – Cambridge, UK

Founders: Yudi Ding and Niels Ramay 

Elevator Pitch: Develops leather-like bio-based materials derived from waste to reduce the environmental footprint of leather in fashion.

Problem they solve: According to the UN, with global warming of 1.5 °C there would be increased risks to health, livelihoods, food security, water supply, human security, and economic growth. Preventing temperatures from rising beyond 1.5 °C would give us a fighting chance. As the fashion/textile industry is responsible for 10-15% of global green house gases emissions, various foundations, UN Alliance for Sustainable Fashion, and other organisations are calling for a new fashion economy.

Impact:  They are a keen advocate for sustainable economy. Not only do they develop sustainable high-quality biomaterial suitable for the fashion industry but also provide a technology platform for creating highly customisable collagen-based biomaterials for other industries.

Their product is intended for leather goods and fashion brands that are seeking sustainable alternative fashion materials, without compromising on quality. Their material is cow-free, climate friendly, non-plastic, waste-derived, non-polluting, while being made of collagen, the same protein that constitutes real leather.
