Abstract:
The project team conducted a site visit following the review of information provided by the customer to conclude a particular location as the preferred site for the first development of solar power plant on an island in the Philippines. This was concluded based on the assessment of four potential sites visited previously, taking into consideration energy reliability, future demand trend, generation capital and O&M cost, and tax and tariff structure as the evaluation criteria for bankability. The solar levelized cost of electricity (LCOE) was significantly lower for the recommended site compared to the other sites for a plant size up to 8MW over a span of 25 years. Based on the preferred location, a preliminary solar energy production assessment (EPA) using a representative block of 1 MWDC ground-mounted photovoltaic (PV) plant was conducted, to generate a site specific, hourly time series energy production profile. The technical modelling assumptions for the EPA was a 1 MWp system of polycrystalline silicon (p-Si) PV modules installed in 3 rows, connected to either one 880 kW central inverter (configuration C1) or forty 20 kW string inverter (configuration C2). Based on the high level long-term global horizontal irradiance (GHI) assessment conducted by the team. The team performed an exhaustive simulation that covered a wide range of energy configurations – over 50 combinations of Solar / Bunker / Energy storage – over a lifespan of 25 years. Simulation inputs were based on demand load trends, the local power supply agreement (PSA) as well as carefully taking into account customers’ comments and their feedback. The simulation study found that it is economically favorable to first install a 5MW solar farm that is progressively upgraded at 0.5MW per annum until the total power generation reaches 8MW so as to achieve the client’s targets of a minimum 16% IRR and an electricity tariff of 11.2295 PhP/kWhr. Based on the load profile of all the 4 feeders in the island and information provided for the 3 HFO low-speed generators and other information provided by the client multiple configurations of energy mixes were simulated.

Abstract:
The current works aim to investigate the energy performance of the building system at the planning stage for sustainable design. Building information modeling has been adopted to simulated a high rise multi-story building in a virtual environment. The Insight has been utilized to access the performance energy in terms of kWh/m2/yr. A case study of sixteen story building has been assessed at its current proposed location, which is at an angle of 370 from the centerline of the building along with the transverse axis and at true north. The study observed that the case resulted in annual consumption of 282 kWh/m2/yr and 276 kWh/m2/yr, respectively. The study has highlighted that adopting virtual technology at design building can help to achieve the optimized sustainable design solutions by accessing energy requirements at the early stage of design inception.

Title: Atoms for Peace, Atoms for War in a Post Inter-mediate Range Missile Treaty
Biography:
Margarita V. Alario, PhD is Professor of Environmental Studies and Sociology at the University of Wisconsin, Whitewater, WI., USA.

Abstract:
The “Atoms for Peace” program launched by president D. Eisenhower in his speech at the UN General Assembly of December 8, 1953, marked a turning point in the uses of nuclear technology. It promised to establish civilian uses of nuclear technology, no doubt one of the central scientific and technological achievements of modernity. The “Atoms for Peace” became the economic and foreign policy benchmark of the Eisenhower Administration, intended on promoting civic and industrial uses of nuclear technology. The results are a bit more complex than that. The recent announcement of USA and Russia to withdraw from the Intermediate Range Nuclear Forces Treaty only exacerbate the complexity. Using the mid-range, structurally informed social theories of risk, this research explores the “Atoms for Peace” program and the broader legacy of ongoing technological and environmental risks. I purport to do so in three steps: 1) I examine the peaceful uses of nuclear technology, and its promises. 2) I examine the legacy of the “Atoms for Peace” program, which paradoxically, may have been the turning point in the history of nuclear proliferation. 3) I explore the implications of the “Atoms for Peace” program with an eye on geopolitical events, as they are currently unraveling.

Abstract:
Water and energy infrastructures are interdependent, as energy is required for water extraction, desalination, treatment and transportation. The energy industry also required water such as water is needed for resource exploitation (fossil fuels), energy conversion processes (refining), power production and transportation. Today, washing and cooling has now become the dominant processes for many of the substantial industries. These industries have in-return affected the quality of water and the aquatic ecosystems that depend on clean water. With continuously growing population and increasing demand for energy consumption is leading to water contamination and its proper treatment has now become a global issue of concern. The water used for energy production becomes contaminated through a variety of ways and carries wide range of contaminants such as inorganics (heavy metals), organics and other water soluble/miscible by-and co-products. Cost effective, sustainable and scalable treatment methods with high removal efficiency for the removal of multiple contaminants are highly desirable. Recently we have developed a sorption technology which uses modified/engineered keratin biopolymers from poultry feathers to remove heavy metals. Besides many other natural materials, keratins proteins provide an excellent role to be used as bio-sorbents or filtration systems to remove toxic contaminants because of their functional groups and side chains as backbone structures. The developed sorbents were tested at lab scale for the removal of 9 trace metals. The results are highly promising with very high sorption affinity ≤80% removal of metals. We are currently testing to expand applicability of these bio-sorbents for a wide range of contaminants. The overall aim is to develop an alternative, low cost and environment friendly sorption technology that is both effective as well as economically viable for industrial scale wastewater treatment to simultaneously remove multiple contaminants produced by energy generation processes.

Abstract:
Environmental health of earth is the primary determinant of the health of ecosystem, but unfortunately human activities, such as industrial development have tempered the natural composition of the environment. Worldwide, a number of industrial units are responsible for the release of effluents which are toxic and these toxins do not only enter in the environment but also tend to magnify as they travel through food chain. Amongst such toxins, manganese Mn (II) is one of the major culprits. This situation is worsening even more as the industrial progress is on its way. Recently, biosorption has come up as effective tool in which biomass of various organisms have been tested. In the present study, the biosorptive potential of algae biomass of green algae (Pithophora oedogonia) has been investigated for removal of toxic heavy metal, such as manganese Mn (II) ions. Various physico-chemical factors have been optimized for biosorptive capacities of sorbates by sorbents. Optimum pH was found to be 4 and optimum temperature was 30OC for manganese Mn (II). Various adsorption models were elucidated to data, such as Langmuir, Freundlich and Temkin isotherms whereas Freundlich model was found to be fittest showing multilayer sorption. Pseudo-second order kinetic model was also found to fit for this study with regression coefficient value of 0.97. Additionally, Fourier Transform Infra-red Spectroscopic studies (FTIR) indicated various electronegative functional groups on the surface of green algae (Pithophora oedogonia) which could possibly offer the binding sites for cations under investigation.

Abstract:
Bioaccumulation of heavy metals in agricultural soil is a serious environmental concern throughout the world. In order to clean up environment, metal sequestration using different plant species has gained considerable attention. One year old sapling of two native biofuel tree species Jatropha curcas L and Pongamia pinnata L, were exposed for 12 months under metal contaminated soil irrigated with textile industry effluent. Prior to application, the effluent was appraised for its physico-chemical analysis. The treatments comprised of T1 (20 ml L-1) and T2 (40 ml L-1) while T0 (control plants) were spiked with tap water. The effluent contained metals in amounts; lead (Pb 42 mg L-1), cadmium (Cd 0.33 mg L-1), arsenic (As 48 µg L-1), total chromium (Cr 41 mg L-1), chromite (CrIII 39 mg L-1) and chromate (CrVI 3 mg L-1). These levels were greater than permissible limits reported by USEPA (0.015 mg L-1 Pb, 0.005 mg L-1 Cd, 10 µg L-1 As and 0.1 mg L-1 Cr). Based on metal accumulation, J. curcas exhibited (P≤0.05) more ability to accumulate (Pb, Cd, As, Cr) in aboveground tissues than roots while more Zn in root than shoots. Memebrane injury index (%) was greater in roots (114%) than (95%) leaves and evans blue dye root uptake was also found higher in P.pinnata (0.92 A600nm) than J.curcas (0.42 A600nm) at elevated effluent level.Thus the two species exhibited differential response for their metal tolerance strategy. Being biodiesel/bioenergy plants and non-food specices, both tree species may be used to clean up metal-contaminated soils.
