Managing Member & CEO

Gibbs Energy, LLC

Since 2003, Mr Maceda has been Founder, President & Managing Member of Gibbs Energy, LLC, a privately held, business product and technology development company committed to the creation of a sustainable energy future. Its largest client was a Fortune 10 oil company for which it developed a liquid-phase, “step change” hydrogen generation technology that will reduce the cost of hydrogen by 50% while capturing all of the carbon as an integral part of the process. Gibbs also spent over six years developing the business plan that became PolyGen Energy. Gibbs also was a finalist in each of the first two rounds of the Department of Energy’s ARPA-E competition seeking transformation technologies, first for a “ Coal-Fired Power Plant Using Electrochemical, Pre-Combustion Carbon Capture,” and second for “The Biocolumn: a Consortial Bioreactor for Making Liquid Fuels, High-Value Hydrocarbon Products and Geocrude.”

Prior to Gibbs, Mr. Maceda was founder and CEO of Ocean Power Corp. a developed of modular, renewably powered desalination systems that had successfully met every cost and performance milestone up until its full listing on the NASDQ on September 10th 2001. As a result of 9/11, its funding sources became unavailable and it was forced into liquidation by two secured creditors who wished to have sole ownership of its flagship patent, “Stirling Engine Having Platelet Heat Exchanging Elements”, which was allowed without comment by the patent office and, of which, Mr Maceda was the lead inventor.

Mr Maceda’s prior company, H Power Corp went public on the NASDQ in 2000 with Lehman Brothers as the lead underwriter. The IPO raised ~$120M at a valuation of approximately $1B. H power was a developer of fuel cell technology that Mr Maceda spun out of an earlier startup in 1991. H Power built the first liquid-fueled fuel cell buses and the first commercially viable hybrid vehicles. The predecessor company, Teledata International, founded in 1987, was developing wireless, wide-area SCADA systems and passive RF ID tags. Fuel cells were in the original plan as power supplies but the company decided to focus on them as the most promising business opportunity.

In the decade before this Mr Maceda had started and sold companies involved in development of the universal power supply, lighting systems, electronic dimmers, video systems, trade show displays and video production and duplication. The common thread through all of these activities has been the development of low-cost, reliable systems.
