ROLE OF INNOVATION AND INFORMATION IN THE GLOBAL QUEST TO ACHIEVE NET ZERO CARBON EMISSIONS
Yogi Goswami¹ ; ¹University of South Florida, Florida, United States;
Paper Id: 331 [Abstract]

As the global leaders grapple with their stated goals to achieve Net Zero Carbon Emissions (NZE) by 2050 or 2060, one must take a serious look at the trends and what needs to be done in the future. Despite all the trends in the right direction, both International Renewable Energy Agency (IRENA) and International Energy Agency (IEA) project that we will fall woefully short of achieving the NZE2050 or limiting the global temperature rise to 1.50C if we continue with the current policies of the countries. While IEA and IRENA, project future estimates of energy based on the present technologies and some incremental improvements, they are not in a position to foresee what innovative new technologies will be available in the future, which might completely change our predictions. As an example, about 25% of all the energy used in the U.S. is for cooling of buildings. Although that percentage is lower for the rest of the world, it is rapidly increasing. Since buildings are cooled exclusively by electrical power, at present we can only hope to replace that electricity with power from renewable energy. However, a very promising innovation on the horizon in scientific and engineering research is to develop coatings for building skins that will emit long wavelength infra-red radiation in the atmospheric window (8–13 mm wavelength) to deep space, which is at a temperature close to absolute zero. The technology known as plasmonic cooling, when developed, will cool the buildings simply by transferring the heat from the buildings to the outer space by radiation. When this technology becomes practical and commercially available, there might not be any need for mechanical cooling or heating of buildings in many parts of the world. Just as we have seen developments in computer and information technologies in the last two decades that we could not even imagine 30 years back, we will see developments in solar and ambient energy space that we can barely imagine today. The presentation will describe some of the transformative developments, including plasmonic cooling that we expect to see in the future. Such transformative information is being communicated via a new open access journal, Solar Compass, journal of the International Solar Alliance.

INNOVATIVE NEW PHOTO-ELECTROCHEMICAL TECHNOLOGY FOR PURIFICATION OF INDOOR AIR
Yogi Goswami¹ ; ¹University of South Florida, Florida, United States;
Paper Id: 332 [Abstract]

Air quality is deteriorating throughout the world due to emissions from power plants, automobiles and industrial processes. In addition, organics used in indoor building materials, carpets, paints and surface finishes add to the indoor air quality problems. According to USEPA, indoor air can be 5 times more polluted than outdoor air. Filtration of air has been the dominant way of improving the indoor air quality, HEPA filters being the standard for air filters. However, many recent studies, especially from the medical literature have shown that filtration of air is not enough to take care of the indoor air quality problems. This is because particles smaller than the pore sizes of the filters, especially, Volatile Organic Chemicals (VOCs) are able to pass through the filters and any micro-organisms trapped on the filters continue to multiply on the filters and eventually get back into the air. Photo-electrochemical oxidation (PECO) technology was introduced in the market by Molekule in 2016, which does not just capture the pollutants but destroys them by oxidation process. The technology has been shown to be effective against biological pollutants, such as, bacteria, viruses and spores and also against molecular pollutants, such as, VOCs. The latest innovative technology for indoor air disinfection and detoxification is Plasmonic Photonic technology. This technology uses nanoparticles to generate surface plasmons, which when subjected to an incident light of the same frequency causes resonance to multiply the effect of incident light to disinfect the indoor air by phtoctalysis. This technology is being introduced to the market as an integral part of the air conditioning system in buildings, as a protection against next viral pandemic.The lecture will describe the science and technology behind each innovation and its impact on indoor air quality and in keeping indoor air disinfected and alleviating the allergy and asthma symptoms of patients.
