# Is there a warranty for Enapter products?

Yes. Enapter products are shipped with a standard warranty of one year. By activating the Enapter Management System (EMS), it can be extended to two years. Enapter is happy to set up customized service agreements with customers and partners requiring longer warranties.

# How much does it cost to produce hydrogen with Enapter’s AEM electrolysers? What is the price of a kg of hydrogen?

The cost of green hydrogen is a function of the volume of power needed, the cost of power supplied, the cost of the electrolyser and its system, and the operative system to run the system. We are suggesting to use these factors in a simple formula to transparently compare pricing.

With the current generation electrolyser EL2.1, the CAPEX1 cost to produce hydrogen is estimated at 6.67 Euro/kg. We are on a mission to bring the cost of hydrogen generation via AEM electrolysis to below 1.5 Euro/kg by 2025.

# Why is AEM the lowest cost electrolyser technology compared to PEM systems and traditional alkaline systems?

AEM is the most promising technology for bringing down the cost of electrolysis, because it combines low stack material cost and low BOP (Balance Of Plant) complexity and cost. The AEM technology allows small, scalable devices which produce pre-compressed, highly purity hydrogen.

# What are the maintenance and operational costs for an Enapter electrolyser, Dryer, water tank and water purification module?

The electrolyser requires a yearly change of electrolyte, which can be performed by the customer in an easy 20 minutes process.

The dryer is maintenance free.

The water tank is maintenance free if in use. If water is stagnant in the tank for a longer period, it may be necessary to wash the tank before usage.

The water purification system is a standard commercial unit with Reverse Osmosis + Resin Filter. The maintenance intervals (cartridge replacement) are typically around 4-6 months with daily use of the electrolyser, but it depends also on the size of the filter chosen and the input water quality.

# What is the cost for stack replacement?

Stack replacements are free within the warranty. Outside of the warranty, Enapter is happy to accept the units back in our factory for a diagnosis and refurbishment. The cost of a complete refurbishment of an EL2.1 has not been set yet, but is estimated to be roughly 50% of the cost of a new machine.

# Is there financing available to buy the Enapter electrolyser?

Currently, Enapter does not provide any financing options to customers. Any orders for electrolysers require a prepayment at order confirmation and are typically fully paid at the time of shipment from the Enapter factory.

# Is shipment included if customers want to return the product within warranty?

From the warranty conditions: Enapter will provide standard ground shipping. If expedited shipping is requested, the shipping costs will be billed to the customer. Enapter does not provide new replacement equipment to distributors or installers who exchange new equipment from their stock to customers in the field at their own discretion.

# What is the cost for Enapter to send technicians on site?

The daily rate for engineers to go on the customer site for installation and training support depends on the location and the nature of the work to be undertaken.

# Is there any consultation or service fee after warranty is expired?

Enapter provides free remote diagnosis and consultation even after the warranty is expired, as long as the Enapter Management System is active and collects monitoring data. After the warranty expires, a monthly/quarterly/yearly subscription is required to keep the remote monitoring system active.

# How does the use rate affect the cost-effectiveness of the electrolyser?

Enapter believes that all hydrogen production must be green, therefore Enapter electrolysers are intended to be run from renewable electricity, which by nature is decentralized and intermittent. If you had electricity available at the right cost for 24 hours, of course that would result in a faster return of invest of your electrolyser. However, that is a rare occurrence and so our machines are designed to be able to start, stop, and adjust production rate as needed.
