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.

Digital Inkjet Printing: An Opportunity for Further Reductions in Solar Energy Costs

With solar on the cusp of economic feasibility in many areas, incremental cost reductions such as those offered by digital inkjet printing technologies can make the difference between moving ahead with solar and sticking with electricity from the local utility

Start of test with solar energy generating noise barriers alongside highway

Alongside the A2 highway near Den Bosch, The Netherlands, two test noise barriers are installed that generate solar energy. The aim of this practical test, that was officially launched 18 June is to assess the economic and technical feasibility of this form of energy generat

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...
