Ports/Trains - Great Non-road EV Opportunities for Utilities

Unlike on-road electric vehicle programs which can be complicated and depend, in part, upon factors outside a utility’s control, non-road programs are less risky and comparatively simple to design, operate, and control.

New method can make cheaper solar energy storage

Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost.

The work is published in Nature Communications.

Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies but "2-D materials" have recently been identified as promising candidates. In general these materials—which famously include graphene—have extraordinary electronic properties. However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale and maintain good performance.

Kevin Sivula and colleagues at EPFL addressed this problem with an innovative and cheap method that uses the boundary between two non-mixing liquids. The researchers focused on one of the best 2-D materials for solar water splitting, called "tungsten diselenide". Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel while also being highly stable.  Cont'd...

Brandsmart USA and ABM To Fund $2 Million Retrofit With PACE Financing Through The Florida Green Energy Works Program

With the funding of a $2.225 million energy efficiency retrofit of the West Palm Beach BrandsMart retail store, the Florida Green Energy Works PACE program is pleased to announce the state's largest PACE project to date. Facility management leader ABM, which previously completed a $1.6 mil retrofit of BrandsMart's Miami location, has designed and is implementing the upgrades in the current project. This project represents the second PACE retrofit in the city of West Palm Beach, which is seeing its first retrofit completed in a few weeks. City officials have long supported PACE financing as a powerful tool for building owners who can utilize the program to fund improvements that pay for themselves with the savings on utility and insurance bills. The Florida Green Energy Works program is a statewide Property Assessed Clean Energy (PACE) program funding energy efficiency, renewable energy, water efficiency and wind mitigation improvements. Under PACE qualified property owners access the upfront cost for building improvements and repay the loan as a non-ad valorem assessment on the property tax.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
