Their transparent solar cells can be applied to glass surfaces, allowing them to generate electricity while still maintaining transparency. This innovative approach opens up new possibilities for solar energy adoption in urban environments, where space for traditional solar panels may be limited.
2. Green Hydrogen Production
Hydrogen has emerged as a promising clean energy carrier, and in 2024, green hydrogen production technologies are taking centre stage. Electrolysis powered by renewable energy sources is being scaled up to produce hydrogen without carbon emissions. This development holds tremendous potential for decarbonizing industries like steel and cement production, where traditional hydrogen production methods rely heavily on fossil fuels.
Heliogen has done notable work in producing green hydrogen. Heliogen’s technology has demonstrated the ability to reach temperatures of over 1,000 degrees Celsius, which is higher than what traditional solar technologies can achieve. This high temperature is particularly advantageous for driving high-temperature electrolysis, a method known for its potential to increase the efficiency of hydrogen production.
3. Carbon Sequestration
Addressing the challenge of excess carbon dioxide in the atmosphere is crucial for mitigating climate change. In 2024, carbon capture and utilisation technologies are gaining momentum. Climate tech innovations in direct air capture and utilisation methods, such as converting captured CO2 into valuable products like synthetic fuels or building materials, are transforming carbon capture from a mitigation strategy to a resource for sustainable development.
CarbonCure Technologies is a cleantech company that has developed a unique technology to reduce the carbon footprint of concrete production. Concrete is a significant source of carbon emissions due to the chemical process involved in cement production. CarbonCure’s solution involves injecting captured carbon dioxide (CO2) into concrete during the mixing process.
4. Smart Grids and Energy Storage
To accommodate the growing share of renewable energy in the grid, smart grids and advanced energy storage solutions are becoming indispensable. In 2024, smart grids equipped with AI-driven technologies are optimising energy distribution, managing demand fluctuations, and enhancing grid resilience. Concurrently, breakthroughs in energy storage, such as advanced battery technologies and grid-scale storage systems, are addressing the intermittent nature of renewable energy sources.
