As Chief Sales & Marketing Officer for Ener1/EnerDel, Dr Warner has global responsibility for both sales and marketing activities. In his previous roles, Dr Warner served as VP of Sales & Marketing for XALT Energy; Director of Sales & Marketing for Magna Steyr Battery Systems NA; Director of Product Management for Boston-Power and held multiple management roles over his 13 years at General Motors. He received his Doctor of Management, Organizational Leadership degree from the University of Phoenix, and his MBA, International Business and Leadership Studies and BA in Industrial Management from Baker College. 

Dr Warner also serves as the President-Elect for the international trade group NAATBatt International, as the Chair for the Society of Automotive Engineers (SAE) Battery Size Standardization Committee and co-Chair for the NAATBatt Bus Battery Safety committee. In 2015 Dr Warner published his book, “The Handbook of Lithium-Ion Battery Pack Design”.


Lithium-ion battery technology has made major strides over the past decade becoming the technology of choice for many major grid and stationary energy storage systems and the de facto solution for virtually all electric drive vehicles. Energy density has more than doubled since the technology was first introduced and costs are beginning to come in line with liquid fuels. With these advances lithium-ion is now making significant headway in the maritime vessel and off-shore platform applications as well as in some of the port-side applications such as gantry cranes.

In comparing these systems, we see many similarities with energy storage systems used in other markets. For instance, many vessels are getting electrified with multi-megawatt hour systems while on the shore many utilities and municipalities are investing in multi-megawatt hour energy storage systems to supplement and support their grid network. In remote regions, islands and military forward operating bases microgrid energy storage systems are being used to supplement diesel genset usage offering significant reductions in the cost of fuel used in those gensets and lengthening the life by reducing the run time. Similarly, for vessels and OSP’s that are using diesel gensets to provide power and housing loads, energy storage systems are being installed that offer up enough fuel savings to pay for themselves in just a few years.

In many cases, when companies begin looking at solutions for maritime applications they are able to start, not from a “clean sheet” but rather from an existing design. These current systems may not meet all of the requirements for a marine application, but most often they can be modified to meet the emerging certifications and type approval requirements for marine applications. In this presentation I will show how an existing energy storage system can be evaluated against marine requirements in order to offer a fast to market solution with high levels of safety, at affordable costs and conforming to multiple global standards.
