We are looking for disruptive deep-tech solutions that provide scalable and impactful solutions to reduce carbon emissions across diverse industries.

‍

Examples of such solutions include, but not limited to:

‍

• Waste-to-resource
  Effective capture and conversion of key waste streams (e.g., point-source carbon, biomass-based or other waste carbon) into value-added products (e.g., point-source or direct CCUS into consumables such as sustainable aviation fuels, marine fuels, chemicals, higher carbon products, fertilisers, proteins) or permanent carbon removal and storage (e.g., point-source or direct CCUS into stable building materials)
• Renewable energy
  To generate cost-effective energy from renewable sources (e.g., wind, solar, hydropower), technologies that accelerate the clean energy transition (e.g., green hydrogen, ammonia), as well as solutions that facilitate the long-term storage of energy and address energy intermittency (e.g., batteries and battery energy storage systems).
• Energy efficiency
  Significantly reduce energy consumption and carbon emissions produced by built environment systems (e.g., building cooling systems) as well as hard-to-abate industries (e.g., manufacturing - food & agriculture, cement, steel, aviation, marine, logistics, healthcare).
• By-product valorisation
  Repurpose carbon- and potassium-rich by-products currently combusted into potassium salt solutions to avoid energy-intensive processing and create higher-value applications.
• Sustainable ammonia
  Develop low-emission, cost-efficient pathways for ammonia production that are less CAPEX-intensive

• Carbon capture
  Lower the cost of CO₂ capture and purification beyond conventional amine-based methods, using alternatives such as solid sorbents or membranes.
• Biofuel feedstocks
  Enable commercially viable use of lignocellulosic biomass(stems, leaves, fibres) to improve yield and cost efficiency in 2G biofuel production.
• Resource efficiency
  Advance solutions to reduce energy and water intensity, improve desalination efficiency beyond reverse osmosis. Manage grid challenges from rapid solar PV integration.

‍

Additionally solutions should be:

• Carbon negative in the overall lifecycle and have zero/minimal externalities
• Technology-based (e.g., physical, chemical); or nature-based solutions (e.g., community models)
• Commercially viable and scalable
• Able to conduct the pilot in Singapore (for technology-based solutions) or within Southeast Asia (for nature-based solutions)

The top two solutions will win S$1 Million each in grant funding.

Two solutions in the Decarbonisation thematic area each stand a chance to receive up to S$1 million in development funding from A*STAR.
