Energy Secretary Steven Chu recently met with a hydrogen technical-advisory subcommittee, raising hopes among hydrogen advocates that the Energy Department would be more receptive to the technology.
The parametric impacts along with some reactor configurations for maximum hydrogen production and technical challenges encountered during hydrothermal gasification processes are also discussed.

2 (1) Although platinum-group metals still play a dominant role as the most efficient catalysts used today for technical hydrogen production, considerable efforts are currently focused on the replacement of the required multielectron-transfer reactivity of these systems with environmentally benign and earth-abundant metals.
Hydrogen cars still face technical hitches, as well as the central challenge: how to cut costs.
On May 10, Dr. Chu participated in a closed-door subcommittee meeting of the department's Hydrogen and Fuel Cell Technical Advisory Committee, or H.T.A.C.
The application of reverse osmosis without any auxiliary technologies to the ultrapurification of technical grade hydrogen peroxide to obtain a quality enough for its use by the semiconductor industry is a great challenge.
In this paper, the potential of multistage reverse osmosis processes to reduce the metallic content of technical grade hydrogen peroxide below the limits fixed by the semiconductor industry is investigated.
In contrast to the conclusion, all of the studies, except one, cited in the AHW Report indicate toxic effects on the eye below 100 ppm H2S [Alberta Health and Wellness (AHW report). Health effects associated with short-term exposure to low levels of hydrogen sulfide (H2S): a technical review, Alberta Health and Wellness, October 2002, 81pp.].
In addition, the AHW Report (2002) mis-presented two studies as 'clinical studies', claiming they reported no evidence of eye effects in humans from 2 and 30 ppm H2S for 30 40 minutes [Alberta Health and Wellness (AHW report). Health effects associated with short-term exposure to low levels of hydrogen sulfide (H2S): a technical review, Alberta Health and Wellness, October 2002, 81pp.].
As a supplementary document to Technical Code for Hydrogen Fuelling Station, a new standard, Safety Technical Regulations for Mobile Hydrogen Refueling Facility, is now under drafting.
