In Search of Perfect Power

What do you do when your research institution is losing roughly half a million dollars annually as a result of multiple electricity outages — and electricity demand keeps rising? If you’re the Illinois Institute of Technology, you turn the challenge into a campuswide learning experience by teaming with the Galvin Electricity Initiative and other experts to design and construct a prototype Perfect Power System (PPS). Even during its implementation, the PPS promises to provide more reliable and sustainable electricity to the university at a lower cost than it had been paying.

CERAWeek 2009: Floundering Economy Eclipses Renewable, Carbon Plans

For the past 26 years, Cambridge Energy Research Associates (CERA) has hosted an annual conference in Houston that is world-renowned for its high-profile speakers and attendees’ willingness to exchange ideas and share industry forecasts. The consensus this year was that the power industry remains strong but market and political forces, often working at cross-purposes, make bringing any new power generation to market more problematic than ever.


Consider CHP for LNG Vaporization

The conversion of liquefied natural gas (LNG) to pipeline-quality gas requires large quantities of low-grade thermal energy that may be available from industrial waste streams, steam power plants, or ocean water at the point of discharging LNG from the tanker. Alternatively, heat may be provided by the combustion of LNG or another fuel. In either case, the large temperature differences between these heat sources and the temperature of the LNG can be used to operate an engine that will offset or eliminate the pumping or fuel costs incurred.

Fast-Tracking a Control System Retrofit

Upgrading a 1970s-era generator control system to new millennium technology in 12 days during a three-week shutdown would require careful planning and teamwork under any circumstances. The quick replacement of the governor and control system at the PT Inco smelter’s hydroelectric generation system is even more impressive because the facility is located in the middle of an Indonesian jungle.

Fire Safety in Modern Hydroelectric Stations

It may seem counterintuitive, but fire can be a serious danger in hydropower plants. In some respects, the danger is even greater than in thermal power stations. Most U.S. hydro plants are 30 to 70 years old but can deliver another 20 or 30 years of service with upgrades — including state-of-the-art fire protection systems. The design options outlined here also apply in large part to other generating stations.


Fossil Fuels + Solar Energy = The Future of Electricity Generation

Renewable energy, though still accounting for a comparatively small portion of overall supply, generates a larger portion of the world’s electricity each year. Combining many of the available solar energy conversion technologies with conventional fossil-fueled technologies could reduce fuel costs while simultaneously helping utilities that are struggling to meet their renewable portfolio goals.

Hydrokinetic Plant Piggybacks on Existing Hydro Plant

Hydrokinetic energy — which generates power by using underwater turbines that harness moving water — is on the rise in the U.S. In January, the first U.S.-licensed, commercial, grid-connected hydrokinetic project installed the first of two 100-kW nameplate-rated turbines downriver from an existing run-of-river hydroelectric plant on the Mississippi River.

Transmission Superhighway or Interconnected Patchwork?

President Obama promoted "green energy" as a signature theme in his presidential campaign. During his first weeks, he reaffirmed his administration’s commitment to renewable resources. In a radio address, he promised to double the nation’s alternative energy capacity within three years and to construct a 3,000-mile transmission grid to "convey this new energy from coast to coast."

Compact, Portable System Converts Trash to Energy

Post-consumer waste could be the newest, ubiquitous fuel source for distributed energy generation if a mobile waste-to-energy conversion system launched this January finds its way onto the parking lots of facilities that produce more than two tons of waste daily. According to its developer, Massachusetts-based IST Energy, the GEM system can process up to 3 tons of waste daily — which can include paper, plastic, food, wood, and agricultural materials — and produce up to 120 kWe and 240 kWth.


New Biogas Plant Runs Purely on Nonedible Materials

German researchers in February said they had developed the first-ever biogas plant to run purely on waste instead of edible raw materials. The team from the Fraunhofer Institute for Ceramic Technologies and Systems IKTS (Institut Keramische Technologien und Systeme) in Dresden said that the plant, which uses a fuel cell to convert the gas into electricity, exclusively uses agricultural waste such as corn stalks — and it generates 30% more biogas than conventional plants.


Norway Leads the Way on CCS

According to a new study from Emerging Energy Research, more than $20 billion will be spent on carbon capture and storage (CCS) projects this year at 50 power generation projects totalling 16 GW around the world. The European Union (EU), with an investment of $11.6 billion, leads all efforts, because it is pressed to achieve a target to reduce carbon emissions by 20% of 1990 levels by 2020. In December, the governing body reached agreement on a climate and energy package, which includes a framework for CCS and a directive on the way EU members and Norway will regulate licenses to ensure reliable carbon storage. The U.S. takes second place, earmarking $6 billion, and Canada is third, at $2.7 billion.

Problems Plague Russia’s Nuclear Power Ambitions

"The Russian Nuclear Industry: Status and Prospects," a February report from a Canadian-based think tank, Centre for International Governance Innovation, examines a revival of Russia’s Soviet-era plans for a massive nuclear expansion within the current state of the country’s nuclear power industry. It concludes that although the industry has been greeted with renewed funding and enthusiasm, achieving its ambitious plans will require the federation to overcome considerable problems and limitations.


Researchers: Spanish Electricity Model Is Unsustainable

The current Spanish electricity model is unsustainable: Carbon dioxide (CO2) emissions are hard to control, demand shows no sign of weakening, and the country is overly dependent on imported fuel. These are the conclusions of a team of scientists from the Institute for Research in Technology of the University of Pontificia Comillas in Madrid, who looked at how the Spanish electricity sector would evolve in four different scenarios.


Toshiba Completes EPC Negotiations for STP

The pace at which next-generation nuclear power is developing in the U.S. accelerated this February as the U.S. arm of Toshiba inked an engineering, procurement, and construction (EPC) agreement with an advanced boiling water reactor (ABWR) nuclear development company jointly owned by NRG Energy and Japan’s Toshiba Corp. The agreement seeks to ensure that the two ABWRs planned to expand the South Texas Project (STP) in Bay City, Texas, will be constructed on time, on budget, and to exacting standards.

Turbines Spinning at Antarctica’s First "Zero-Emissions" Station

About 110 years after the Belgica expedition — a polar voyage organized by the Geographical Royal Society to establish the world’s first Antarctic scientific research program — a new, unique research station sponsored by the Belgian Federal Government has been commissioned. Inaugurated on Feb. 15 after two years of construction, the Princess Elizabeth Station (Figure 4) is the only polar base to run entirely on renewable energies.

Proposed Federal RPS Needs Rewrite

A 16% national RPS would require almost a 500% increase in renewable generation in the next decade, or about 32,000 MW. EIA data show that the U.S. had about 8% renewables online at the end of 2007. What’s worse is that very few existing projects would count toward the requirements of this proposed legislation.
