Tech Bundle


Sustainability is no longer a buzzword, but an environmental, economic and social driver that is changing our daily lives. In the business community, committing to sustainable practices is vital as the negative impacts of climate change have become more prevalent, with the potential to affect everything from supply chain to profitability.

To achieve sustainable development, the Singapore Green Plan sets bold targets to accelerate decarbonisation and sustainability efforts. Sustainability requires transformation, and most organisations are exploring how to consolidate new technologies and innovation to progress further. Technology is shaping sustainability and enabling advanced levels of productivity, efficiency, resource and cost savings, all of which can help to minimise the impact on the environment.

To catalyse enterprises’ net-zero journey, we have curated technological innovations and co-creation opportunities in four thematic areas: Circular Economy, Food Security, Low Carbon Economy and Sustainable Living.

Ambient Condition Mineral Carbonation for Carbon Sequestration
Carbon dioxide (CO2) captured from flue gas emissions need to be safely sequestered to prevent re-emission into the atmosphere. One promising method to do so is mineral carbonation, which converts the captured CO2 into solid carbonates that are inert and permanently stable. However, the process for mineral carbonation commonly involves high pressure, temperature and a pure CO2 supply, or the use of chemical additives to activate the raw materials for reaction which severely limits its application. This technology offer is an ambient condition mineral carbonation process which avoids the high energy requirements of traditional mineralisation processes. It is adaptable and versatile, able to use a mixture of various raw materials such as incineration ash, concrete waste and steel slag as feedstock. This technology can be coupled directly to an efficient CO2 capture process, which eliminates the need to purify and recover the CO2 prior to the carbonation reaction. The carbonated aggregates (e.g. sand) from this process can be used as material for construction or land reclamation. In addition, if incineration ash is used as a feedstock, the heavy metals in it can be immobilised using this technology. The technology owner is looking for partners especially those in building & construction, waste management and high CO2 emitting industries for further co-development and test bedding of the solution. The technology owner is also keen to license this technology as well.
Carbon Capture from Dilute Flue Gases Using Aqueous Ammonia
Nearly half of Singapore’s carbon dioxide (CO2) emissions come from dilute flue gases (3 – 5% CO2 concentration) emitted by natural gas-fired power plants and refineries processes. CO2 capture from dilute flue gases is very challenging due to the large volumes of gases that needs to be processed to capture each tonne of CO2. Moreover, conventional CO2 capture solvent such as monoethanolamine (MEA) is corrosive in nature and struggles to keep up with the CO2 volume requirements. Furthermore, using MEA as a solvent is an energy intensive process which severely limits its application. This technology offer is a process which uses aqueous ammonia as a substitute for MEA to capture CO2. Aqueous ammonia is cheaper, safer, and more readily available compared to MEA. In addition, absorption/desorption using aqueous ammonia occurs at much lower temperature (50-80°C vs >120°C) compared to MEA. This significantly reduces both the CAPEX and OPEX of the system. The technology owner is looking for partners especially those in high CO2 emitting industries for further co-development and test bedding of the solution. The technology owner is also keen to license this technology as well.
AI for End-To-End Carbon Accounting and Management
As governments and financial institutions take bold steps to reduce their impact on the environment, organisations of all shapes and sizes face immense pressure to accelerate their sustainability journey and reduce their carbon footprint. Most organisations currently rely on consultants and spreadsheets to calculate their carboon footprint using data that is up to a year old. This technology offer is an Artificial Intelligence (AI)-powered Software-as-a-Service (SaaS) platform that integrates with key enterprise IT systems and other platforms to obtain live activity data across the value chain. The technology is applicable across industries and provides better visibility into the organisation’s footprint and reduces the time required to generate disclosure report by up to 90%. The technology owner is looking for partners and collaborators in the Energy, Oil & Gas, Manufacturing, and Logistics industries to conduct pilot projects and further develop the niche industry requirements of the products.
Enabling Carbon Capture via Hydrogen Separation Membrane
Today, up to 95% of hydrogen (H2) produced is termed grey H2 as it is formed via steam methane reforming (SMR) using fossil fuels such as natural gas. This hydrogen is used in producing everything from fuels to plastics and is aptly named grey H2 as the carbon dioxide (CO2) from this reaction is expensive to capture and is often released or sent to the stack to be burnt off. With the global net-zero CO2 emissions target looming, there is an urgent need for technologies that can improve the efficiency of processes using grey hydrogen and economically capture the released CO2 making grey H2 into blue H2. This technology offer is a hydrogen separation membrane that reduces the cost of hydrogen purification and carbon capture. It is a temperature and corrosion-resistant membrane that is able to selectively filter out H2. By splitting syngas into H2 and CO2-rich streams, it simultaneously purifies hydrogen and pre-concentrates the CO2 for transport and sequestration. Furthermore, there is an additional benefit that waste H2 can be inexpensively recovered to improve the overall process efficiency. Hydrogen plants incorporating this technology now produce blue H2 and can generate additional income through higher efficiencies, hydrotreater margins, and carbon credits. The technology owner is seeking partners and collaborators, especially those in the oil and gas refineries or other H2 intensive industries, for pilot trials of their technology.
Spray Cooling System for Data Centres
Data centres in Singapore consume about 7% of the electricity generated annually. A large proportion of the energy consumption (~50%) is for the cooling system necessary to keep the servers operating reliably under Singapore’s hot and humid ambient conditions. Current cooling systems rely on energy-demanding chillers and computer room air handlers to produce cold air which is passed through the IT equipment to mitigate the heat generated via sensible cooling. The technology owner has developed a spray cooling system that aims to eliminate the need for chillers and reduce the energy requirements of the other associated equipment in the data centre cooling application. The spray cooling system uses dielectric coolant which is dispersed in small droplets through a spray nozzle that directly impinges on electronic components and absorbs heat from the operating heated server by evaporative or droplet impingement cooling mechanism. The vaporised coolant is then recovered by a condensing coil cooled by ambient temperature water (i.e. no cooling required by chillers) from a cooling tower, through which the heat is rejected to the environment. The technology owner is seeking industry partners to co-develop and pilot the technology for data centre applications and in space or equipment that require high heat load cooling applications.
A Sustainable Packaging Solution for Home Care Products
Through its proprietary encapsulation technique, the company converts a wide range of household chemicals, especially those in liquid forms, into solid, concentrated, water dispersible, single-use dosages that are completely water and plastic free. They can be easily diluted with water prior to use and ensure consumers do not use too much of the product, fulfilling consumers’ expectations for sustainability and user-friendliness. The company seeks partnership with consumer goods companies for a joint development of new home care products, putting together their competency in encapsulation technology and the partners' expertise in the actives and applications.
Advanced Materials For Sustainable Agriculture
The company helps growers and farmers become more efficient and sustainable in their practices by innovatively solving insect, weed, and diseases problems. Through applying its proprietary controlled release technology, the company converts a wide range of commercially available actives such as fertilizers, fungicides, herbicides, and pesticides into solid, ready-to-use, self-metering dosages that release actives only as needed. When applied, these products enable an overall operational cost reduction of 15-20%, reduce actives consumption by 2-3 times, and reduce application rates by 3-4 times. The company seeks to co-develop such products with growers and farmers. Once tested and ready for commercialization, it will undertake the local product registration (if required), as well as the manufacture and supply of the products directly to the growers and farmers at a pre-agreed price.
Spatial-Social-Economic Urban Analytics
Many existing smart city solutions only show the impact of urban development, but few show the impact that urbanisation imposes on daily activities and long-term outcomes such as population obesity and job availability/accessibility. In short, such solutions show the activities e.g. large crowds are visiting the neighbourhood park, that are happening in real-time (what), the location (where), and the time that they occur (when), but do not have the ability to include data that makes it possible to explain the reason for such activities (why). In order to bring about any intervention or identify missed opportunities, understanding the reason behind such activity is vital. This technology utilises data on city infrastructure systems to help users understand how and where the built environment creates a set of physical constraints that influence what planned and unplanned activities are possible, and in turn how this influences long term outcomes including health and climate change. This technology imports, translates and combines datasets into spatialised models which are used to generate analytics outputs. These outputs include a comprehensive explanation of the way streets, pedestrian networks, public transport and land use interact with each other. In this manner, socio-economic and/or demographic datasets can be linked, enabling people and places to be combined in a single analytical model.
Vanadium Redox Flow Battery for Enhanced Energy Storage Solution
Today, the cost of energy generated by renewable sources is less than conventional energy. However, current energy storage solutions (e.g. Lithium-ion battery etc.) used to harness energy from renewables are expensive, unsafe and unreliable which has severely impeded the adoption and development of such renewable sources. Hence, there is a need for a cost efficient, safe, environmentally friendly and reliable energy storage system (ESS) to address these existing issues. This technology offer is a vanadium redox flow battery (VRFB) as a promising ESS. Unlike lithium-ion and lead acid batteries, VRFB has the flexibility to design and customise its power and energy density independently. This results in enhanced performance in terms of round-trip efficiency, energy density and thermal window as well as lowered levelised cost of storage when benchmarket against lithium-ion battery based ESS for long discharge duration. The VRFB also uses a unique stack design and an organic additive mixture on the electrolyte that improves the thermal stability and allows for 25% increase in energy efficiency when compared to other VRFB solutions.It also reduces safety risks related to over-charging, discharging and thermal runaways. This VRFB ESS is stable for up to 25 years with no electrolyte degradation and is made with environemtally friendly materials. The technology owner is seeking partner and collaborators especially those in renewable energy, large scale utility and microgrid projects to test bed their technology.
