Climate tech encompasses a range of technologies designed to combat climate change by reducing greenhouse gas emissions, advancing renewable energy, and enhancing energy efficiency. These technologies play a critical role in promoting environmental sustainability and implementing adaptation strategies to address the impacts of climate change.
 
Sharing a snapshot below.

The following are the innovations in climate tech technologies in different sectors:

Energy Sector:

Batteries:

• Innovations prioritize enhancing battery energy density and fast-charging capabilities, while advances in battery recycling technologies aim to reduce environmental impact.

Energy Storage:

• Innovation in high-performance materials is essential for advancing stationary batteries, with anticipated demand reaching 350 GW for short-to-mid-term and 400 GW for long-duration energy storage by CY30.

Hydrogen:

• Provides deep decarbonization of sectors responsible for approximately 20% of global emissions, enables renewable energy integration by storing it as molecules, enabling grid blending and transportation efficiency.

Nuclear:

• Generation II and Generation III+ nuclear reactors, totaling ~440 units and currently supplying ~10% of global electricity generation, require accelerated innovation in traditional Generation III+ and Generation IV technologies to achieve cost reductions

Renewable Energy:

• Renewable capacity additions increased by ~50% to ~510 GW in CY23, highlighting the need for technological innovation such as organic thin film cells to reduce costs and enhance efficiency.

Sustainable Fuels:

• Alternatives to fossil hydrocarbon fuels, such as conventional biomass-based fuels, drop-in sustainable fuels, and non-drop-in fuels, are essential to decarbonize hard-to-abate areas that cannot be electrified.

Environment Sector:

CCUS (Carbon Capture, Utilization, and Storage):

• Technologies capturing CO2 from industrial processes at point sources, followed by transportation, conversion, or storage, are employed to reduce residual emissions after other reduction efforts have been exhausted.

Circular Technologies:

• Attempts to reduce CO2 emissions from materials over their lifespan, while maximizing their lifetime value, involve shifting production from primary to recycling processes and reducing the greenhouse gas intensity of materials.

Engineered Carbon Removals:

• A variety of technology-based methods (such as DACS, BECCS, biochar, bio-oil, and enhanced weathering) are employed to eliminate atmospheric CO2, addressing residual carbon emissions once other reduction strategies have been implemented.

Technologies Supporting Natural Climate Solutions:

• Nature-based projects, including afforestation, reforestation, peatland restoration, fire and savannah management, etc., remove carbon from the atmosphere or prevent emissions from being produced.

Technologies to Produce Alternative Proteins:

• Innovation is essential to optimize plant genetics and extrusion technologies for maximizing health and sensory characteristics, and regulatory clarity is essential for alternative proteins to enhance consumer and investor confidence.

Infrastructure Sector:

Heat Pumps:

• Using a refrigerant cycle with gas compression and expansion efficiently transfers heat from the evaporator to the condenser, this technique is 2.0-4.5 times more efficient than conventional gas furnaces and boilers.

These technologies help reduce greenhouse gas emissions and promote sustainability.
