UK-based Ultra Green Group has made an investment in a start-up called OM Energy Ltd. OM Energy has been developing an Electro Hydrogen Generator (EHG), which produces hydrogen on board a vehicle from water for use as fuel. Anyone that has been following AutoblogGreen for a while is aware that we generally don't think much of such on-board hydrogen generators for cars. Until now, most of them have relied solely on drawing electrical energy from the alternator to electrolyze the water, a process

Last week we ignited some healthy discussion in the comments with my post on the (de)merits of on-board hydrogen generators and injectors. While few could argue with my basic thermodynamic analysis of the process, defenders repeated the claim from producers of these systems that something magical happens when you add hydrogen to the air fuel mixture of an engine. We've looked into this a little further in recent days including with a powertrain engineer that actually understands combustion proce

One of the biggest cost drivers for electrolyzers and fuel cells is the need for precious metals like platinum to act as catalysts. At $1,700-2,000 per ounce, it can rapidly drive the costs of a fuel cell through the roof. As a result one of the main areas of development in fuel cells has been reduced use of catalysts and new catalyst materials. MIT Chemist Daniel Nocera has been working on this problem and discovered that cobalt and phosphate may make an excellent substitute in electrolyzers. A
