Greenovate! – ACAL Next Gen Fuel Cell Technology
Real world stories about innovators and innovative companies are an important way to learn and we place high value on them at Innovation Excellence. We are very pleased to begin a series of case studies on companies who have been curated by Hult International Business School and Center for Innovation, Excellence and Leadership (IXL Center) in their book Greenovate!
The book Greenovate! documents 53 case studies that are defined by “sustainable, green innovations” (or “green ovations”). Each profile combines business innovation with a synthesized concept of sustainability, from startups to leading global organizations. The first case study in this special series is:
ACAL ENERGY – Next Gen Fuel Cell Technology
ACAL Energy developed a new method for generating current within a fuel cell by using a proprietary recirculating liquid cathode technology that performs better and at lower cost than existing fuel cell systems.
As with other fuel cell systems, the only by-products of the fuel cells are water and heat
In addition, ACAL’s technology reduces the required amount of platinum, a rare and expensive mineral.
The new technology enables fuel cell systems to operate up to five times longer than is currently possible.
ACAL Energy cuts the amount of platinum used in fuel cells by 80% and reduces the price of fuel cells by 40%.
Fuel cells are unique in energy delivery, combining benefits such as: low or zero emissions, high efficiency and reliability, multi-fuel capability, no noise pollution.
Dr Andrew Creeth, the founder of ACAL Energy Ltd with more than 15 years scientific experience, invented a new technology for ACAL.
According to Clean Edge, the fuel cell market is expected to grow steadily to $15.6 billion over the next decade — about 10x its 2008 size.
To cut carbon emissions, UK government sets up organization and business incubators to support start-ups and emerging technologies.
Fuel cells require the use of precious metals (usually platinum) as catalysts — the scarcity and expense of these metals make the fuel cells unaffordable for mass use.
The company needed funds in order to take the technology forward from small-scale laboratory systems to manufacturable prototypes.
Sophisticated components and systems are required to ensure fuel cell reliability contributing to the high cost of current systems.
FlowCathTM technology is new on the market and the lack of brand recognition is a challenge to attracting customers.
Acal’s FlowCathTM technology removes the need for platinum, replacing it with a proprietary liquid that is continuously pumped through the cell.
The company is supported by UK VCs, Japanese and European corporations, and public investors — altogether, they provided £7 million in funding.
The use of liquid instead of platinum allows simplification of equipment, thus eliminating the need for a hydration system.
Carbon Trust, a UK government organization, assesses and supports the development of FlowCathTM, increasing its credibility.
FlowCathTM allows an 80% reduction of platinum used in fuel cells and a 40% decrease in fuel cell price
ACAL Energy built a state-of-the-art lab and a 4,000 m2 plant, growing from 5 to 23 employees in 18 months.
The use of the liquid improves the fuel cell’s durability to more than 1,500 hours with no loss in performance.
ACAL Energy was a finalist in 2009 Carbon Trust Innovation Awards, which recognize innovative, low-carbon companies.
The company’s near term strategy is to build partnerships with key supply chain companies and fuel cell OEMs. In the long term it plans to enter more markets: transportation as well as industrial and domestic distributed energy.
