The urgent need to address climate change is recognised globally with Australia adopting a net zero emissions target by 2050 and commitments to reduce carbon emissions by 2030. The adoption of hydrogen as a substitute for carbon-containing fossil fuels would prevent emissions of greenhouse gases. However, hydrogen is itself an indirect greenhouse gas and any leakage of hydrogen in the atmosphere because of fugitive emissions from a hydrogen economy will impact the climate, partially offsetting the climate benefits of a reduction in CO2. Hydrogen is a volatile, and odorless gas with relatively small molecular size and low viscosity; thus, hydrogen systems are highly prone to leakage. As such, there is an urgent need to build capacity to detect and minimise fugitive hydrogen emissions to the environment. To address the risk of hydrogen fugitive emissions and leaks, robust, reliable, real-time, power efficient, and scalable sensing and leak detection technologies, including advanced hydrogen gas sensors should be employed. Currently many different types of hydrogen sensor are commercially available or in development. However, to meet the demands of an evolving future hydrogen economy, ongoing research has focused on continuously enhancing sensitivity, selectivity, response time, low detection limit and reliability in addition to reducing sensor size, cost, and power consumption. We have developed innovative gas sensing technologies via synthesising hybrid photoactive nanomaterials using facile chemical methods. These nanomaterials include Pd-TiO2 hollow nanospheres, rGO-Pd-TiO2 and Pd-TiO2 solid nanospheres that have shown promising results to detect hydrogen gas at room or low operating temperature (i.e., low power requirements) with high sensitivity and selectivity and fast response (within seconds) by using photoexcitation. This talk discusses benefits of nanomaterial hybridisation and photoexcitation to hydrogen gas sensing, the underlying sensing mechanisms, and strategies to overcome current limitations.

The Vancouver Section of the IEEE promotes the exchange of technical information and awareness of the local engineering community by:
- Hosting evening, half-day, or full-day technical presentations and seminars on topics of current interest
- Organizing tours of local companies, research labs, and industrial sites
- Arranging for local support and participation in engineering conferences and symposia held in Vancouver.
Other important activities include:
- Recognizing local members by nominating them for advancement in IEEE membership grade and/or IEEE technical and service awards,
- Arranging for industry support of projects organized by IEEE student branches and chapters, and,
- Organizing events or activities concerning either technology or public policy for the general public.
The Vancouver Section was established on August 22, 1911. The Section encompasses the geographical area of the province of BC, except for Vancouver Island (which is part of the Victoria Section). The Section currently has about 2200 active members, including 325 students at BCIT, SFU, and UBC. It is the fourth largest Section in Canada.
The Section operates on a fiscal year that runs from May - April of each year. The Annual General Meeting and election of new officers are held on the second Monday of each May. Meetings and social events are generally held from September - April.
The Section's nine active technical chapters represent 15 of the 37 technical societies and councils of IEEE and are listed on the menu bar to the left. Each chapter holds 5-6 technical meetings or tours each year. Some chapters organize a few half or full day seminars, and a distinguished lecture or two.
The Section also has active committees responsible for:
- Advertising
- Awards
- Communications
- Conference Activity
- Continuing Education
- GOLD (Graduates of the Last Decade)
- History
- Membership Development
- Professional Activities
- Publicity
IEEE Continuing education courses are offered online at http://www.ieee.org/web/education/home/index.html
Local courses are also offered at the Department of Electrical and Computer Engineering at UBC, the School of Engineering Science at SFU, and at the British Columbia Institute of Technology.
The Section publishes a newsletter, "IEEE CONTACT", 9 times each year (from September - May) that is emailed to members.
