Hydrogen-on-Demand (HOD) System for Fuel Cell Portable Power Applications

The lack of hydrogen infrastructure has been the major barrier to fuel cell commercialisation, especially for portable applications. Some companies offer hydrogen solutions based on liquid sodium borohydride. These commercial solutions, however, have some drawbacks. Sodium borohydride solution faces problems, such as, precious catalyst with short lifespan, leakage, orientation issues, complex maintenance and impurities in the hydrogen generated. The impurities in hydrogen would accumulate in the anode chamber of a polymer electrolyte membrane fuel cell (PEMFC) and deactivate the electro-catalysis of hydrogen oxidation reactions, resulting in system breakdown. The limitations of these commercial products highlighted the need for a hydrogen-on-demand system that satisfies the U.S department of energy's (DOE) standards in terms of system weight, volume, cost and efficiency. The hydrogen-on-demand (HOD) system developed by the technology provider, has the attributes of ease of control, good handling safety, full hydrolysis of NaBH4, low cost catalyst with durable lifespan and high energy density. The HOD system could possibly unify the PEMFC applications by offering common hydrogen platform, and thereby increasing the customers’ flexibility in choosing different products without getting tied to proprietary hydrogen solution. This would help to penetrate and grow the consumer electronics and lifestyle market that is currently dominated by batteries.

Non-iterative Simultaneous Localization and Mapping (NI-SLAM)

Non-iterative Simultaneous Localization and Mapping (NI-SLAM) is a patented method for position tracking and environment dense reconstruction, using affordable sensors such as depth camera and inertial sensors. Compared to traditional SLAM methods, the superior real-time processing speed of NI-SLAM is achieved by an innovative method of data registration that performs point-cloud matching in Fourier Domain.

A Novel Graph Optimization Approach to Localization (GOAL) for Unmanned Systems

GOAL is concerned with 2-D plane and 3-D space localization technology for robots. The methodology leverages on ultra-wideband (UWB) aided localization system and can be extended to application with other sensors such as inertial measurement unit (IMU), Wi-Fi, Optical Flow and Cameras.Unlike existing Filter-based localization algorithms which have unacceptable estimation error in altitude, this technology provides high accuracy in the estimation in altitude without adding other sensors for altitude estimation, which saves cost of localization system. Also, this technology has the function for rejecting Non-line-of-sight (NLOS) measurements, which enables this technology to NLOS environment. The design of flexible moving window in this technology decreases the computational resources and increases the robustness to short duration lost in signal, which enables this technology to be applied to robots with ultra-low power processor.

Intelligent Internet of Things (IoT) Data Management with Blockchain

The blockchain data management framework for the open, multi-party, and decentralized industrial & commercial markets. Blockchain has been introduced to support distributed, peer-to-peer (P2P) database in which no single entity maintains data and transactions of the system. Instead, all parties in the network can generate, verify, secure, and share the data with privacy and integrity.

Hierarchical Transactive Energy Management System

Hierarchical Transactive Energy Management System (HTEMS) is proposed not only to promote purchase/sale of energy transactions but also to solve the intermittency and variability of renewable energy sources (RESs) when they are integrated as part of the utility grid. A power hardware-in-the-loop (PHIL) platform is developed to test out the hardware controllers and converter design via the 4-quadrant three-phaser power amplifiers and to enhance the research capabilities for the smart grid technologies.A low-cost transformer-less flexible power quality conditioner (FPQC) is invented to solve the power quality (PQ) problems of power systems due to the increasing usage of power converters. A series of multiport converters are developed to facilitate the integration of RESs into the power grid with the least number of components and acceptable cost.

Recycling Plastics into Fuels and Chemicals Using Sunlight

This technology provides a more eco-friendly solution to convert non-biodegradable plastics into fuels and chemical feedstocks. In Singapore, about 96% of the plastics waste is incinerated, which contributes to Singapore���s CO2 emissions and aggravates global climate change. The remaining 4% is recycled only after the plastics have been cleaned and pre-treated by energy-intensive processes. Furthermore, many of these plastics are indiscriminately discarded worldwide, resulting in the widespread pollution of the marine ecosystems.The technology, when fully developed, offers a potentially greener solution to turn non-biodegradable plastics, such as polyethylene, polypropylene, polystyrene, and other such derivatives into chemical feedstocks, some of which can be directly used in fuel cells. The technology uses light to trigger the chemical degradation, but could eventually involve a combination of light and electricity instead of heat, which will be more easily deployed worldwide. This technology should be of interest to companies manufacturing plastics that need end-of-life solutions to their products, and also companies and government agencies that are working to recycle plastics.
