STG International provides small-scale low cost solar thermal power plant for electrifying clinics and schools in developing countries. In the world's poor rural areas schools and health clinics struggle to provide adequate service without electricity or hot water. Electrification of these institutions proceeds slowly with expensive grid extension, photovoltaic (PV) panels or diesel generators. STG has developed a better solution: a miniaturized solar thermal power plant using low cost solar collectors and a novel ORC engine that can provide clean electricity and hot water at a fraction of the cost of competing systems.

Solar Engineering Solution (SES) offers breakthrough solar thermal technologies to deliver clean and cost-efficient cooling and heating solutions for commercial buildings. Heating, cooling, and hot water account for more than 40% of total energy use in buildings (over $170 B/yr), and represents 10% of US CO2 emission. Our solar thermal collector, smart control and other innovations, enable building owners to achieve payback within 3-5 years by a typical 85% reduction in energy operating costs.

ZCI Carbon to Methanol technology reduces greenhouse gasses while boosting energy independence and the bottom line.

hydroGEN Technologies is commercializing a novel technology that leverages energy stored in waste to produce low cost, predictably priced high purity hydrogen. High purity hydrogen is a $10B market and is primarily produced through the reformation of price volatile natural gas and the electrolysis of water. The high price is due to purification steps and high transportation costs. Our advantages include low cost energy input and scalability allowing for onsite generation at competitive prices.

Teleos Solar makes a solar energy widely affordable. Their patent-pending crystallization process-step solution will enable CIGS thin-film solar manufacturers to increase module power output by up to 80% and cut module cost per watt almost in half. The CEO was a manager at a global solar equipment supplier and the technical team has 35 years combined in semiconductor research. It is estimated that the CIGS manufacturing equipment market could reach $10 billion by 2020. They are seeking seed funding.

Clean Energy Innovations develops and markets a proprietary process capable of delivering an increase of at least 25% in the energy extracted from a battery during one discharge cycle. The CEI process promises to be a critical factor in the growth of rechargeable batteries which is expected to be a $50 billion market by 2015. Despite large R & D investment in the industry, the rate of performance improvement is relatively slow. Dramatic improvements in cost, performance, or weight of rechargeable batteries will add high value to the end products where they are used. The CEI reproducible laboratory test results of its patent pending process, IPS™ (Interfacial Process Stimulation), demonstrate its claims for significant performance improvements in both Nickel Metal Hydride and Lithium Ion batteries. The process will work with any type of rechargeable battery. The IPS™ process can be readily integrated into existing control systems, by adding a simple low cost logic component into the battery power management modules. This means there is a minimal amount of incremental development and incremental bill-of-material cost. This is a disruptive technology which brings immediate performance results that match the more costly industry developments underway in battery chemistries and controls. Through the implementation of software-driven advances in the operating system of the battery, IPS™ achieves clear improvements, but is also compatible and synergistic with these R & D efforts. Key is that CEI’s process has been shown to be far more cost effective - it achieves the same results with a lower investment by at least four orders of magnitude. CEI seeks partnership arrangements with market leaders where IPS™ will be a major driver to advances within important industry sectors such as mobile devices, electric vehicles and storage for renewable energy installations. CEI has a passion for solutions that support the major global objectives for environmental health and security, energy independence, and economic growth. CEI believes that IPS™ will have a major impact on these important objectives.
