Short Subjects

Next week, New York City. The Cleantech Venture Forum III starts on Tuesday afternoon Oct 21 with some pre-conference workshops. I’ll be presenting information about Federal technology resources. The conference gets into full swing on Wed.

DOE Office of Electric Transmission & Distribution (OETD)

Back in March, we thought announcements were imminent. (See UFTO Note – T&D R&D Gaining Attention, 21 Mar 2003.) Little did we realize the kinds of struggles that would ensue internally in DOE over which people, programs and budgets would be won or lost by which office. The new office started its work nonetheless, judging from numerous appearances by its chief.

Humid Air Injection Boosts CT Output

Additional megawatt-hours (MWH) can be obtained at low cost during peak demand periods from gas turbines and combined cycle power plants by injecting externally compressed, humidified, and heated air into a combustion turbine (CT) up-stream of combustors. This novel approach is denoted as CT-HAI, (Humidified Air Injection) for simple cycles and CC-HAI for combined cycles.

Update on Alchemix HydroMax

The HydroMax technology uses any carbon source including low sulfur and high sulfur coal to produce electricity, hydrogen and syngases which can be used as fuel for gas-fired power plants or converted into diesel, jet fuel, gasoline or ammonia. Alternate carbon sources include petroleum coke, municipal waste, biomass and shredded tires.

Bicarb Cleans Up Stack Gas Emissions

The same baking soda (sodium bicarbonate) sold in grocery stores and used for a 101 things around the home is also one of the best solutions to scrub emissions from coal-fired power plants. Purification of flue gas emissions using sodium bicarbonate has always been recognized as a highly effective process for removing SO2, SO3, NOx and heavy metal compounds from flue gas.

Non-Thermal Plasma H2, no CO2

There are dozens of plasma companies, often focused on medical waste, and some on power (with coal or some waste stream as the feedstock). (See footnote) Usually these are hot plasmas, and tend to be expensive due to the materials problems at high temperature. In a plasma, sometimes called the 4th state of matter, material is very highly ionized by an electrical arc discharge.

Firefly Re-invents the Lead Acid Battery

In early May, Caterpillar announced the formation of a new spin-off company called Firefly Energy Inc., whose purpose is to complete the development and commercialization of a dramatically improved lead acid battery technology. The entire research program, people and technology have been transferred out of CAT into the new startup after several years of in-house research.

Energy Efficiency as a Resource

This event was a real eye opener. The energy efficiency crowd is on a roll, very much back from near death. These are the champions of Energy Efficiency (EE) and Demand Response (DR, not to be confused with distributed resources) who push for equal treatment of the demand side “resource” alongside generation and supply.
