Real-time monitoring of wastewater quality remains an unsolved challenge in the treatment industry. The standard method of biological oxygen demand (BOD) yields slow results (five days); another standard method, chemical oxygen demand (COD), uses hazardous chemicals and does not provide direct information on potential for ecological pollution. The treatment industry has expressed need for the development of new, meaningful fast-responding measurement methods to complement (or replace) the current standard methods. The overall objective of this project is to develop deployable instrument for continuous in-line monitoring of treated wastewater quality. Phase I demonstrated a new electrochemical measurement process for the determination of wastewater constituents as alternative to present standard measurements. Laboratory studies and comparisons to standard methods confirmed the feasibility of the proposed approach in simulant mixtures and real-world wastewater samples. Phase II program will feature further optimization of the measurement process to define and establish a new metric paralleled with an extensive comparison with standard BOD and COD measurements. Phase II program will also include design, fabrication, and integration of Giners PureSens probe as a portable sensor for on-site testing of wastewater samples at multiple treatment facilities.

Measurement and monitoring of subsurface microbial activity plays an important role in studying the extent of heavy metal, radionuclide, and industrial chemical contamination at the Department of Energy (DOE) sites and their impact on the surrounding environment. Development of field-deployable microbial monitoring systems is critical in achieving long-term success for environmental restoration efforts. The proposed program will develop a field portable instrument that would enable rapid detection and continuous monitoring of select microorganisms in groundwater and soil samples. This electrochemical sensor instrument employs novel sample processing techniques and utilizes reusable electrodes and highly sensitive detection algorithms to allow for low level detection limits specific to the presence of targeted nucleic acid sequences judiciously selected from genes and microorganisms that have key roles in environmental restoration and bioremediation The feasibility of Giners electrochemical hybridization sensing approach has been demonstrated for detection of model Geobacter gene sequences in water and groundwater. The Phase I program achieved microbial level of detection (LOD) values that are three orders of magnitude lower than the average measured quantity of Geobacter population. The Phase II program will feature detection of additional microorganisms relevant to bioremediation applications, design and fabrication of a field prototype instrument, and an extensive environmental water and soil testing using field samples. Giner will advance its portable microbial sensor technology by expanding the portfolio of microorganisms, refinement of its sensing algorithms, and development of field-friendly sample treatment protocols. Commercial Applications and Other Benefits The highest initial impact of the proposed sensor technology would be for enabling sustainable bioremediation technologies to ensure the successful implementation of microbial communities in contaminated sites such as Superfund sites, wetlands, and coastal environments. Successful development of this technology will enable more effective management of environment to provide wide-spread application of bioremediation technologies and to help maintain biodiversity in ecosystem. Other versions of the proposed system could be used to monitor bacterial contamination of food, drinking water, and household or clinical surfaces to provide fast and accurate screening of microorganisms at low cost.

Hydrogen production for mobility and energy storage from proton exchange membrane (PEM) water electrolysis is attractive due to its efficiency, ability to quickly cycle up and down, and deliver hydrogen with high and differential pressure. However, capital costs are high due to expensive materials, especially the membrane and catalyst. Though membrane costs are predicted to decrease, precious metal catalysts costs will come to control capital costs as this technology matures. Decreasing the precious metal requirement for PEM electrolysis is therefore vital for the wide spread use of this technology. The overall objective of the Phase IIB project is to commercialize low precious metal loading, high-performance catalysts for PEM water electrolysis that we have successfully developed in our Phase II project, which may significantly lower the capital cost of water electrolyzers. In Phase II project, we have developed and demonstrated two advanced catalysts. These two catalysts enable reduction of the precious metal catalyst loading on the anode by an order of magnitude, while maintaining performance equivalent to an industry-standard anode. These catalysts also demonstrate good endurance over a 1000-hour test. In the proposed Phase IIB, we will further develop and transition the innovative catalyst synthesis technology to successful commercialization. First, we will scale up the catalyst synthesis process to make short production of these catalysts. Second, we will develop an effective Membrane and Electrode Assembly (MEA) fabrication process to make reproducible and full-sized MEAs. These MEAs will be subsequently integrated into large-size electrolyzers to test their performance and durability. The success of the Phase IIB project will lead to the commercialization of these advanced catalysts for hydrogen production from water electrolysis. These catalysts enable reduction of precious metal catalyst loading on the anode by an order of magnitude while maintaining performance equivalent to an industry-standard catalyst. Alternatively, operating costs (dominated by the cost of electricity), the highest cost of PEM hydrogen production, can be lowered by increasing the loading of these catalysts. These combined efforts will make the commercialization of PEM water electrolysis for production more viable.

The non-aqueous ionomer dispersion technology invented at Los Alamos National Laboratory (LANL) has demonstrated great potential to significantly improve the lifetime of proton exchange membrane (PEM) fuel cells and electrolyzers. However, further validation and improvements are needed to make this technology commercially viable. The overall objective of this project is to further develop and commercialize LANLs ionomer dispersion technology. The ionomer dispersion technology will be integrated with dimension- stabilized membrane (DSM) platform to create more durable membrane and electrode assemblies (MEAs) for PEM fuel cells and electrolyzers in an economically feasible way. In our Phase I project, this ionomer dispersion technology was successfully combined with DSM technology to create more durable MEAs. These MEAs simultaneously demonstrated remarkable chemical stability and mechanically stability after being subjected to accelerated stress tests. In the Phase II project, we will further develop this technology in more processable, scalable, and profitable ways. We will use a roll-to-roll process to make full-sized MEAs that combine non- aqueous ionomer dispersion and DSMs. We will evaluate these MEAs in more extensive and practical conditions and explore their potential markets. The successful completion of this project will improve the durability and performance of PEM fuel cells and electrolyzers, significantly reducing the cost of fuel cell vehicles. This will lead to a widespread deployment of fuel cell vehicles, which will relieve the nations heavy dependence on imported oil and reduce air pollutants.

Giner, Inc. has developed an advanced high pressure electrochemical oxygen concentrator (EOC) that offers a simple alternative to the use of pressure swing adsorption (PSA) systems to generate high pressure oxygen for the International Space Station (ISS) and future human space flight applications. The high pressure EOC is based on proven electrolyzer technology demonstrated at Giner and delivers a continuous stream of dry oxygen with a highly controllable oxygen pressure (0-3600 psi) by feeding a low pressure humidified oxygen stream into the cathode side of the stack where oxygen is consumed. The generation of pure oxygen at 3600 psig is particularly applicable for filling tanks used for extravehicular activity (EVA). The benefits of using this technology rather than a standard high or large pressure differential electrolyzer stack include: 1.) significantly reduced membrane degradation resulting in an improvement in stack lifetime, 2.) increased safety as there is no risk of producing a combustible gas mixture in the event of gas crossover through the MEA, and 3.) simplified balance of plant (BOP) for the reason that typical liquid cathode feed electrolyzer stacks require sophisticated water management. Giner further simplified the high pressure EOC BOP by integrating a low pressure static vapor feed electrolyzer (SVFE) into a shared-end-plate stack.

Ammonia (NH3) is an extremely important feedstock for producing nitrogen fertilizers, such as anhydrous ammonium nitrate (NH4NO3) and urea (CO(NH2)2), that provide essential nutrition for crop vitality. The worldwide production of ammonia is more than 100 million tons per year. The conventional Haber-Bosch ammonia production process requires high pressure and temperature (up to 300 atm and 500°C) and is, as such, extremely energy-intensive.The proposed Phase II project aims to further scale up the electrochemical synthesis of ammonia at lower temperature and pressure, and integrate this technology with off-peak renewable energy towards building distributed ammonia plants. The reactants are nitrogen and water that are immediately available and abundant. High-performance electrocatalysts and hybrid anion exchange membrane will be used to further enhance the ammonia production rate and process stability. These efforts may help transform the electrochemical production of ammonia to a more practical level.The successful application of this technology will lead to ammonia synthesis via a more environmentally-benign and economically viable approach, compared to the conventional Haber-Bosch process. The synthesized ammonia using renewable energy can be widely used as a feedstock for fertilizers in agriculture. The ammonia can also be considered as a means of storing surplus renewable energy during off-peak hours.
