The intermittent nature of renewable energy sources is a huge burden on the power grid, making flexible and economical energy storage an essential step to a greener future. Researchers at Oregon State University (OSU) and the University of Florida have now devised a way to conveniently store and release energy harvested through concentrated solar power (CSP) plants, improving on the cost and energy density of previous systems and preparing this technology for the smart grid.While standard solar panels convert sunlight directly into electricity, concentrated solar power plants focus an array of mirrors onto a solar receiver and use the resulting heat to drive an electricity-generating steam turbine. These systems tend to be low-cost, safe, long lasting and highly efficient, but they must be coupled to powerful and flexible energy storage to work at full effect.

The smart grid: It’s the power-system modernization effort that U.S. utilities are building to meet the country’s growing demands for electricity. But it’s not confined to power plants and substations–if you have a smart meter, a key piece of smart grid technology already is attached to your house.That means that Americans’ willingness to accept those meters, and use the features they provide, serves an important role in developing a more reliable, secure electrical grid.

Demand response (DR) is becoming a growing part of the resource base that electric system operators rely on to maintain reliability on the grid. Market liberalization, economic pressures, and environmental regulations are all moving toward a path of fewer traditional central power plants and more distributed energy resources (DER) to address future energy needs. Advanced technologies can help speed this transition and make it more reliable along the way. For example, automated demand response (ADR) systems

The U.S. Environmental Protection Agency’s Clean Power Plan (CPP) Final Rule, issued earlier this week, sets goals and mandates for the nation’s power plants to reduce the greenhouse gas emissions that create pollution. But many of the nation’s largest electric utilities have already made significant reductions in the last couple years, according to a report produced, in part, by Ceres — the most comprehensive analysis to date on U.S. power plant air pollution emissions, which examined carbon dioxide (CO2), nitrogen oxides (NOx), sulfur dioxide (SO2), and mercury emissions from the nation’s 100 largest electric power producers.

Air pollution is a challenge everywhere and while, in the United States, the Environmental Protection Agency (EPA) is targeting power plants with its Clean Power Plan, other countries like China are capitalizing on the growing popularity of electric buses.
