Ballard Celebrates 40-Year Corporate Anniversary

• A global leader in the fuel cell industry
• Paving the way for widespread adoption of sustainable, zero-emission mobility solutions

VANCOUVER, May 22, 2019 /CNW/ - Ballard Power Systems (NASDAQ: BLDP; TSX: BLDP) today announced a celebration of the 40-year anniversary since its founding in 1979 (www.ballard.com). The Company is hosting a celebratory reception at its headquarters today, with a number of dignitaries in attendance including Mr. Paul Howard, a Ballard co-founder and energy visionary. Recognition of Ballard's longevity is also part of the 2019 Impulse Summit for Hydrogen and Fuel Cells (https://hyfcell.com), being held this week at the Sheraton Vancouver Wall Center.

Ballard - Celebrating 40 Years (CNW Group/Ballard Power Systems Inc.)

Ballard Power Systems was founded in Vancouver by Geoffrey Ballard, Keith Prater and Paul Howard to conduct research and development of high-energy lithium batteries. Four years later, after a research breakthrough, proton exchange membrane (PEM) fuel cells became a primary focus of the company's work and Ballard has since established itself as a global leader in the PEM fuel cell industry. Ballard's IPO and listing on the Toronto Stock Exchange occurred in 1993 and the Company was subsequently listed on the Nasdaq exchange in 1995. For further details regarding key milestones in the Company's history, please visit http://ballard.com/about-ballard/our-history.

Mr. Paul Howard, Co-founder of Ballard Power Systems commented in a recent interview, "It takes time for new technologies to really manifest themselves into practical use …. So, I say to the doubters: we need the benefits of hydrogen. For humankind to survive, we need hydrogen, which is essentially a limitless source of energy."

Randy MacEwen, Ballard President and CEO stated, "At Ballard, our vision is simple and enduring – we deliver fuel cell power for a sustainable planet. What has changed today is the ability to point to numbers – actual technology and products operating in the field. The industry today is powering over 25,000 fuel cell forklifts, more than 12,000 fuel cell cars, and over 2,000 fuel cell buses and commercial trucks, all of which are operating in the field. Two or three years ago, those numbers would have been de minimis. So for the first time in our 40-year history, we can point to real market adoption happening."

Mr. MacEwen continued, "At the same time, the technology has been validated. We've delivered dramatic cost reduction on the technology and product front while also seeing significant performance improvements. The next leg of cost reduction will continue to include innovations – technology, product and manufacturing innovations and improvements that will drive costs down – but it will also include, for the first time, the benefits of scaling and supply chain. There is mounting evidence that the shift to zero-emission transportation is accelerating and that fuel cell electric vehicles, or FCEVs, will play an integral role."

Over its history, Ballard has invested more than $1 billion in research and development to advance PEM fuel cell technology and has produced over 5 megawatts of PEM fuel cell products. Today Ballard's 700+ employees design, manufacture and sell fuel cell products that contribute to CO₂ emission reductions in various mobility applications.

Ballard believes there are large and attractive addressable markets and use cases for Heavy and Medium Duty Motive applications – such as city buses, coaches, delivery trucks, drayage trucks, long-haul trucks, trains, trams and certain marine applications – where FCEVs offer a strong value proposition. These vehicles require long daily range, fast refueling, carry a heavy payload and also enable zero-emissions. Ballard expects early adoption in markets where the value proposition is strongest and where the barriers to hydrogen refueling infrastructure are lowest, such as centralized depot refueling.  These market segments are now bracing for a shift away from pure diesel vehicles into alternative powertrain systems.
