The largest difference is that the Enjay energy is recovered thermal waste energy from the manufacturing processes on site, rather than new energy from the grid. The energy delivered from an Enjay installation will displace significant parts of the current fossil energy purchased – most likely natural gas. Recovered energy from Enjay has two main competitive advantages versus fossil energy: It is 100% renewable AND it is up to 50% cheaper.

Short answer: It is easier than it might appear: Enjay provides the money needed to finance the full installation and instead of charging for the components and labour, Enjay charges for the energy delivered – just like any other energy company. And since recovered energy is significantly cheaper than energy sourced from the grid, Enjay can offer the energy at half the price and yet cover the Capex investment.

Long answer: It is easier than it might appear: Enjay provides the money needed to finance the full installation and instead of charging for the components and labour, Enjay charges for the energy delivered over repeatable ten year periods. The enabler for this solution is: An industrial manufacturing company currently purchases natural gas to combust and generate the thermal energy required in the production processes. The natural gas cost consists of, 1) the natural gas stock exchange price (alternatively the agreed price in the procurement agreement), 2) transmission and distribution charges, 3) metering and service fees, 4) taxes and levies and last but not least – and often overlooked – 5) an inefficiency ratio in the burner, leading to losses. The recovered energy Enjay delivers, suffers from none of these five cost drivers, the energy, once recovered is zero cost. As Enjay sells the energy up to 50% cheaper than the cost for natural gas based energy, Enjay can, over the ten year contract, absorb the required installation and component Capex money and simultaneously generate the profit levels required for long term stable operation.

Short answer: You wouldn’t. You are welcome to purchase the Enjay equipment and make the investment as for any normal ROI project.

Long answer: You wouldn’t. You are welcome to purchase the Enjay equipment and make the investment as for any normal ROI project. However, generally, what is stopping you as an organization to get energy efficiency

improvement projects done, is not a lack of understanding that they would save you a shed-load of money from your energy budget, as well as decrease your fossil emissions, which would potentially save even more money. No, what’s stopping you is normally the fact that you cannot secure the required Capex – as Capex is severly restricted, even for projects with short ROI times. This is the reason why you would want to implement Enjay’s Energy as a Service – you would source a considerable amount of 100% renewable energy, making a significant contribution towards your Net Zero plan, and since the cost of the energy is 50% of what you would pay if you procured that energy via combusting natural gas, you will also create a considerable decrease in your energy cost budget from day one. Without having to fight to release Capex funds.

Because the kWhs delivered from Enjay, will displace kWhs you currently procure from your gas supplier. And the kWhs you procure from Enjay are cheaper than the ones you procure from your gas supplier, so if decreasing your total energy costs is at all part of your management agenda, then you would want to buy recovered energy from Enjay.

Recovered energy has the same inherent commercial benefit that renewable energy sources all have built in: Once the installation of the required equipment is made, the natural resource required to generate the power, is free, it carries no cost. However, when you procure your thermal energy from burning natural gas, you constantly need to purchase the gas from a supplier, at a hefty price. Compare it to Wind power, where once the wind power plant is built, the cost for wind is zero. Or compare it to solar power, where the solar influx also is zero cost. The same is true for the thermal energy recovered by Enjay’s technology – it carries no cost for energy generation, for energy transmission or distribution, and it even doesn’t register for taxes and levies.

Because the kWhs delivered from Enjay are up to 50% cheaper than the ones you procure from your gas supplier, so it’s a simple matter of decreasing your total energy costs.

A recovered kWh is the best kWh from a Net Zero Carbon perspective. Even if many things are hard for experts in fossil fuels and global warming to agree upon, this is one fact that everyone can actually rally around: A recovered kWh that displaces a kWh generated from fossil fuels, will result in a 100% decrease in fossil emissions.

Short answer: By purchasing recovered energy from Enjay, you significantly decrease the amount of fossil fuel you burn in your thermal processes, which leads to a direct decrease of your Scope 1 emissions. Long answer: By purchasing recovered energy from Enjay, you significantly decrease the amount of fossil fuel you burn in your thermal processes, which leads to a direct decrease of your Scope 1 emissions. The deeper explanation is that Scope 1 emissions are defined as the fossil emissions generated by internal production processes. A major component of those emissions, is the fossil CO2

emitted from burning fossil fuels in technical equipment for generation of thermal heat, like burners, boilers and generators. The recovered energy will directly decrease the amount of fossil fuel required to keep the process running, because every single kWh of recovered energy will displace a kWh of of fossil fuels used in burners, boiler and generators.

The short answer: If the major contaminants in your warm exhaust air consists of particles, then the chances that our technology could provide significant energy savings to your manufacturing processes, are very good.

The long answer: This is however not the only prerequisite for a successful implementation, there are many questions regarding the set-up of your energy system on site to answer as well. This is why Enjay follows a designed 6-step program to efficiently find out where the opportunities are, how large they are, and how we could realize them. The first step of the program; “Screening”, answers the main questions regarding technical fit, energy saving potential and a first look at installation requirements. If the project clears this step, we move on to; Step 2 Feasibility Study, where all parameters are thoroughly canvased. It results in technical drawings, technical description and a business proposal, including a quote – all designed to provide the customer with all documentation required to make a yes/no decision to continue the project. The Feasibility Study involves detailed technical analysis, system design, and preparation of a formal proposal. To reflect the scope of this work, a fee of €2,500 applies. The fee is fully credited if you choose to accept the quote and proceed with the project. If the study concludes that the installation cannot be carried out due to technical constraints, or if we determine that the project is not viable, the fee is waived. Step 3 to 6 guides us the rest of the way to realization of the energy and emissions savings, from installation to commissioning to operation.

Short answer: Enjay’s breakthrough technology is the only heat exchanger technology that can be deployed in industrial exhaust air contaminated with high levels of air bourne particles.

Long answer: Enjay’s breakthrough technology is the only technology that can be deployed in industrial exhaust air contaminated with high levels of air bourne particles, because it is based on completely different design parameters than a standard heat exchanger for deployment in air streams. All standard heat exchanger designs are optimized for energy transfer using as small a physical space as possible. This design relies heavily upon attracting the air flowing through the unit towards the energy transferring surfaces. The problem is, when you attract the air, you also attract the air bourne particles towards the energy transferring surfaces. And once the particles collide with the surface, there is a very large risk that they stick. Over time the particles form a build up on the surfaces, which first decreases the efficiency of energy transfer, and eventually clogs the unit fully, leading to costly production downtime. Enjay’s patented breakthrough heat exchanger design is completely the opposite, it is designed to repel the air away from the energy transferring surfaces. This means that also the air bourne particles are repelled away from the surfaces, which means the risk for the particles to stick, is decreased by more than 95%, resulting in a heat exchanger that remains both efficient and unclogged over prolonged periods of time, despite sever particle loads in the axhaust air.

Short answer: No technical equipment can be deployed and then expected to operate without service, maintenance and monitoring, especially not in environments as aggressive and challenging as contaminated industrial exhaust air. But compared to a standard heat exchanger, Enjay’s heat exchanger will remain remarkably much cleaner. Still, the units will require periodical service and maintenance, typically 1 to 4 times per year.

Long answer: No technical equipment can be deployed and then expected to operate without service, maintenance and monitoring, especially not in environments as aggressive and challenging as contaminated industrial exhaust air. But compared to a standard heat exchanger, Enjay’s heat exchanger will remain remarkably much cleaner. Still, the units will require periodical service and maintenance, typically 1 to 4 times per year. Enjay’s energy recovery equipment is always installed as a ventilation by-pass, mainly as a contingency to avoid any risks of production down-time in the unlikely event of unforeseen issues with the Enjay equipment. The by-pass is also very useful during scheduled cleaning events, as the by-pass can be closed to re-route the extract air away from the Enjay units, allowing for maintenance work while the production could potentially continue running. It isn’t possible to answer the question “How often do the Enjay units require maintenance and cleaning?” with one standard answer. The frequency of maintenance and cleaning depends on the particle load and the type of contaminants present in the industrial exhaust air where the Enjay unit is deployed. However, it can be illustrated with examples from the more than 200 installations that are currently operational. In fastfood, represented mainly by Burger King, it is technically enough to clean the unit once every 12 months, but national rules may stipulate more frequent cleanings than technically required. In industrial laundries, represented by CWS and Cleanlease, the cleaning cycle varies from once per month to four times per year. In foundries the typical cleaning regime is twice per year. Enjay monitors all installations remotely and have early-warning systems in place, both to indicate if the efficiency is dropping, or if the air pressure drop for some reason increases, indicating that the installation needs maintenance. Equally important is that the maintenance team on site needs to include the Enjay units in their periodic inspections, and, if required, clean the unit according to the instructions.

Short answer: We mean that Enjay’s technology unlocks a new power source – comparable to solar power, nuclear power or hydro power. With Enjay’s technology, we can now recover waste heat from production processes around the globe, effectively unlocking a new power source: Waste Heat Power.

Long answer: We mean that Enjay’s technology unlocks a new power source – comparable to solar power, nuclear power or hydro power. Currently, because there hasn’t been robust technology available, the thermal heat from production processes around the globe is wasted, as it is ventilated straight out to the ambient air. With Enjay’s technology, we can now recover this waste heat, effectively unlocking a new power source: Waste Heat Power. Waste Heat Power has the potential to displace significant fossil energy, as it excels at displacing natural gas from a wide range of thermal manufacturing processes. Waste Heat Power is available on the sites of industrial manufacturing companies, and since it is both 100% renewable and considerably cheaper than other thermal energy from other power sources, it has immense potential to save both cost and fossil emissions.

Yes indeed. There are different surveys published on the magnitude of Waste Heat Power. One of the surveys presenting the most conservative number for Waste Heat power potential, was published by McKinsey in 2024, and it concludes that the current potential for Waste Heat Power is around 3.100 GWh annually. To put that in perspective: All the nuclear power plants in the world, generated 2.800 GWhs of electricity in 2024.

So, yes, Waste Heat Power, being slightly larger in current potential than all nuclear power available, has considerable value at a commercial scale.

Short answer: No doubt. Waste Heat Power has the same inherent commercial benefit that renewable energy sources all have built in: Once the installation of the required equipment is made, the natural resource required to generate the power, carries no cost.

Long answer: No doubt. Waste Heat Power has the same inherent commercial benefit that renewable energy sources all have built in: Once the installation of the required equipment is made, the natural resource required to generate the power, carries no cost. Compare it to Wind power, where once the wind power plant is built, the cost for wind is zero. Or compare it to solar, where the solar influx also is zero cost. The same is true for Waste Heat Power – the thermal energy recovered by Enjay’s technology, carries no cost for energy generation, for energy transmission or distribution, and it even doesn’t register for taxes and levies. Enjay converts this business value to the Energy as a Service offering, enabling industrial manufacturing companies to decrease energy cost by 50%, while also offering to avoid the Capex investment, which generally is the reason why energy efficiency improvement projects are not realized.

The short answer: Enjay have spent a lot of time together with customers to device a design and an installation execution that minimizes the disruption to production. If your manufacturing runs 24/7, there is no avoiding some production disruption, but on other operation hours schemes, chances are the installation work involving the necessity to shut down, can be minimized, maybe even avoided.

The long answer: Enjay have spent a lot of time together with customers to device a design and an installation execution that minimizes the disruption to production. The result is that Enjay’s heat exchanger in the duct/chimney from the manufacturing process, is always built as a ventilation by-pass. This serves three main purposes; the first is that the initial installation can be well prepared, and the disruption of potential production time when the by-pass is integrated into the existing duct/chimney can be mimimized. The second purpose is contingency – if an unforeseen issue appears with the energy recovery installation, the by-pass can be closed, and the manufacturing process is instantly returned to the original state, thus avoiding potential production down time. The third reason is that the by-pass is very useful when it is time for the scheduled cleaning/maintenance, as it may allow for the production to continue running in parallel. If your manufacturing runs on a 24/7 basis, some production down time will be required, but on any other operating hour scheme, chances are production down time could be avoided altogether by careful preparation and execution.

The short answer: As this would represent a major risk to our customers, we have spent considerable time devising a design and a strategy to manage this risk. The main source of contingency is that the ventilation installation is built as a by-pass. By closing the by-pass Enjay’s installation is fully de-coupled and the extract air from the production process is immediately re-routed to the original configuration and any risks for production down-time due to the Enjay installation hence avoided. But this is a true last-resort action; more detail under “Long answer”.

The long answer: As this would represent a major risk to our customers, we have spent considerable time devising a design and a strategy to manage the potential risk.

By closing the by-pass, Enjay’s installation is fully de-coupled and the extract air from the production process is immediately re-routed to the original configuration and any risks for production down-time due to the Enjay installation hence avoided. Generally however, the closing of the by-pass is considered a true last-resort action, an action that is very rarely activated. The installation has a remote monitoring system, tracking parameters that will give early-warnings of any indication of building issues within the ventilation system or the energy recovery system. The early-warning indications are delivered directly to the site’s maintenance system, enabling staff to check on the source of the indications and rectify them before they grow to issues. Should the indications turn to issues despite the early-warnings, checks and attempts to rectify, the last-resort contingency where the by-pass I closed off can be activated. As already mentioned above, this immediately re-routes to the extract air to the original configuration, hence avoiding any risks for production down-time due to the Enjay installation. While the by-pass is closed, the Enjay installation can be debugged and measures to restore full functionality can be taken, before the by-pass is re-opened and the energy recovery restored.
