Solar Tech Outlook

Manufacturers scale up for utility applications.

Photovoltaics technology is emerging as a generation alternative—both for centralized and distributed facilities. Solar industry executives say their companies are overcoming obstacles to large-scale implementation. With advances in design and manufacturing, the future looks bright for utility-scale solar power.

Constitutional questions about state-mandated renewable tariffs.

Despite state efforts to follow the European model of state-mandated feed-in tariffs to promote renewable power, these actions won’t pass Constitutional muster. The Supremacy Clause makes a formidable legal barrier.

V2G Shuffle

Smart charging is just the start of the electric vehicle revolution.

Electric vehicles (EV) now rolling off automakers’ production lines are expensive and limited in range, but they mark a technological tipping point. By tapping into the smart grid, EVs promise to free transportation fuel from the physical medium—raising its practical value while simultaneously diminishing its cost.

Solar Eclipse

Wind faces a nano-scale threat.

For decades now, wind turbines have been generating electricity more cheaply than most other (non-hydro) renewable energy technologies. In particular, wind has maintained a comfortable lead over solar energy in the price-per-kWh race. That’s destined to change.

T&D and Smart Grid

The ZigBee Alliance and the Wi-Fi Alliance entered an agreement to collaborate on wireless home area networks (HAN) for smart-grid applications. The initial focus of the collaboration will be ZigBeeSmart Energy Profile 2.0, which is the next-generation energy management protocol for smart grid-enabled homes based on today’s successful ZigBeeSmart Energy Profile. The ZigBeeSmart Energy Profile 2.0 is expected to be extended to operate over Wi-Fi technology as a result of the collaboration.

Generation

FEI Company, a diversified scientific instruments company providing electron and ion-beam microscopes and tools for nanoscale applications, completed a multiple system installation at the Materials Ageing Institute (MAI) in France, a utility-oriented research center financed by Electricite de France, the Tokyo Electric Power Co., the Kansai Electric Power Co. and the U.S. Electric Power Research Institute.

Generation

Siemens Energy has been awarded an 18-month, $300,000 R&D program by the Illinois Clean Coal Institute to study the effects of coal and coal-derived syngas combustion on the behavior of material and coating degradation in utility boiler and gas turbine environments. Focus areas of the research program will explore materials degradation modes in integrated gasification combined-cycle (IGCC) systems and utility boilers.

Integrating Renewables

Opportunity for advancement or exercise in futility?

The power grid has been slow to embrace renewable energy sources. In order to allow renewable energy sources to evolve into a solution rather than a headache, new tools and processes will need to be developed to forecast and control renewable production capabilities.

Greening Connecticut

Aligning renewable energy incentives with RPS compliance.

States’ green energy policies are being used to serve multiple agendas. Lawmakers should revisit their renewable incentive programs to better align them with policy goals. A regional approach will yield a more efficient portfolio.

Solar Expansion

Technologies are scaling up quickly to meet industry needs.

Like other California electric utilities, San Francisco-based Pacific Gas & Electric (PG&E) has been scrambling to meet the state’s renewable portfolio standard (RPS), which requires suppliers to obtain at least 20 percent of their power from renewable energy sources by 2010. Though the RPS includes a variety of technologies, renewables developers are choosing utility-scale solar power more than any other resource, says Hal La Flash, PG&E’s director of emerging clean technologies.
