COVER focus: Renewable Top Plants
Developing a Solution for Utility-Scale Storage
A long-duration energy storage solution has proved elusive, though a
Canadian company has developed a compressed air system technology,
showcased at a new plant in Ontario, that promises to deliver a range of
grid services to electricity markets.
Award-Winning Hydropower Project Helps Electrify Ethiopia
Ethiopia is among the African nations where a rapidly growing
population also means more electricity is needed to keep up with that
growth. A hydropower dam project that was years in the making, with
numerous construction challenges, is now part of the country’s solution
to providing more power.
Turning a Brownfield into a Brightfield
A $40 million remediation effort, including years of cleanup led by
the U.S. Environmental Protection Agency (EPA) and the Indiana
Department of Environmental Management, have turned an EPA Superfund
site into a solar power showcase in Kokomo, Indiana.
Delingha: A Leap for Molten Salt Tower CSP Technology
A concentrated solar power (CSP) tower plant located on a
high-altitude plateau in China is a model for solar tower technology.
The Delingha plant features several breakthrough technologies, including
pairing solar with molten salt storage, smart heliostats, and
large-scale mirror field cluster control.
WindGas Falkenhagen: Pioneering ‘Green’ Gas Production
A Uniper facility in Germany has been a proving ground for new
technologies to produce “green” hydrogen and methane from wind power,
approaches that could benefit several industries including the power
sector.
Floating Platforms Are an Offshore Wind Gamechanger
A wind project off the coast of Portugal may feature only three
turbines, but it’s the project’s design that sets it apart. The turbines
are sited on floating platforms, enabling their installation in a
deepwater area that previously would not be suitable or accessible for
wind turbines.
Features
Nuclear Waste
Age-Old Problem in Search of a Solution
The debate over how to safely store and dispose of the world’s spent
nuclear fuel and other radioactive waste continues. Analysts agree deep
geological repositories are the best answer, but decisions about where
to site such facilities, and what technologies should be used, remain
elusive.
Reciprocating Engines
Benefits of Reciprocating Engines in Power Generation
Power plants using reciprocating engines could provide the
flexibility needed to help stabilize the use of intermittent renewables
and support their integration onto the grid. The engines bring
reliability and resiliency, along with efficiency, and are often a
lower-cost option to turbines.
Energy Storage
Energy Storage: America’s New R&D Priority to Secure the Grid
The research and development of long-duration energy storage
technologies to partner with fossil fuel-fired power generation is now a
priority for the U.S. Department of Energy (DOE), as the DOE makes
reliable and affordable electricity a priority.
Plant Equipment
Putting Idle Turbine Generators to Work
The evolution of power generation has consequences for the equipment
used in power plants. There are many turbines that today sit idle, but
that doesn’t mean they’re obsolete. Old or underutilized turbines can be
converted fora dual purpose—generation and synchronous condensing.
Retrofits enable
these units to deliver reactive power.
Project Management
Technology in Construction: Matching Solutions to Specific Challenges
Companies building power generation projects need to cut through the
noise of new technologies. In the third and final part of this series,
we learn that instead of trying to guess what’s in the future, these
groups should familiarize themselves with tools already available and
adopted, and invest in them where it makes sense.
