In this research project, the separator of rechargeable hybrid aqueous batteries (REHABs) is mechanically strengthened with graphene oxide derivatives. ReHABs comprise of a lithium intercalation cathode, zinc anode and an aqueous electrolyte. One of the problems with current ReHABs is the zinc dendritic growth and propagation from the anode, which significantly reduces its operating lifetime. After cycles of charge/discharge, these dendrites grow and propagate through the separator and eventually reach the cathode, thus shortening the battery.
Emissions control is an important part of any environmental policy. However, in dense urban environments and other locations, it is important to deal with sound as well. To ensure effective pollutant mitigation while also ensuring minimal acoustic disturbance, it is necessary to look at computer models that look at these factors simultaneously. This work will provide SPI with tools necessary for acoustic models while ensuring that their current products meet environmental requirements.
The proposed internship aims to study how the performance and the reliability of mechanical energy storage systems influence their life-cycle cost (LCC), including the acquisition cost, the maintenance, and the energy costs. First, the effect of the variation of the design parameters on the performance and acquisition cost of the product will be assessed. Second, the effect of materials and processes on the reliability and the LCC of product will be studied. Lastly, the energy cost associated with the operation of the product will be analyzed.
ABRI-Tech and Memorial University (MUN) have been collaborating to optimize ABRI-Techs pyrolysis system to convert woody biomass (i.e. demolition wood waste, sawmill residues, forest residues, agricultural and other residues) to bioproducts.
The Canadian government has increased its focus on regulating wastewater to the environment. The advent of new regulations has resulted in many municipalities requiring substantial upgrades to minimize release of nutrients promoting eutrophic water bodies. Traditional wastewater treatment technologies are in some cases cost prohibitive. Bishop Water Technologies (BWT) provides an ecofriendly and cost-effective technology for treating Canadian wastewater (municipal and industrial) while removing nutrients to rivers and lakes.
The proposed study will develop seismic design guidelines for retrofitting deficient concrete bridge columns with sprayed fiber reinforced plastic (FRP). Seismically deficient bridge columns (with different aspect ratios and transverse reinforcement ratios) retrofitted with composites will be tested under reverse cyclic loading. The tests will determine various damage states in terms of strain and drift.
Wind energy is the fastest growing source of electricity in Canada. However, its supply is not aligned with the energy demand, thus energy storage becomes important. The Power to Gas process (P2G) is a promising technology in which electrical energy is converted into chemical energy (methane). Methane can be stored in already existing natural gas distribution infrastructure. Within the P2G process, excess electricity is converted to hydrogen via water electrolysis and subsequently converted with CO2 (biogas upgrading) to methane.
The rapid depletion of fossil fuels (such as Coal, Natural gas, Oil etc.) and the escalation in environmental pollution have prompted increased investigations in the field of alternative energy sources. In this context, solar cells are being studied to satisfy the increasing power needs of today’s society as photovoltaic power uses pollution-free energy source, solar energy. Silicon solar cells are still very expensive due to both the using of expensive materials and the employing costly processing steps.
This research will identify best practices for the design of renewable energy investment programs targeting the social housing sector. Involving mixed methods of research, including literature review, interjurisdictional scan, and strategic interviews with third party experts, the research will result in a set of actionable recommendations for provincial and federal governments, municipal social housing authorities, and other third party private sector actors involved in the renewable energy and social housing sectors.
Ocean wave energy converters (WECs) are devices that utilize ocean energy to produce electricity or fresh water. A key stage in developing these devices is scale model testing in wave tanks, as it allows the power generation capabilities of a design to be evaluated at a much lower cost and with no environmental risk compared to full scale testing in the ocean. One of the challenges with designing scale models of WECs is the power take-off (PTO) system which can be infeasible to implement at small scales.
