Reducing generator running time by up to 90%.
The hybrid system provides power 24/7, and automatically controls the management of power delivery, enabling operators to focus on managing their workload without disruption, whilst saving costs and reducing emissions.
We used to be filling our diesel tank at least once a week and now we’re probably getting four times longer between fills.
Hybrid Energy Overview
How Hybrid Systems Work
The hybrid system can be set with several parameters which dictate when the generator is turned on or off. For example, timers can be set to ensure the generator does not switch on in quiet hours, or the generator can switch on or off if a certain power load threshold is breached.
Hybrid systems can be integrated into new facilities at the planning stage, or as a retrofit solution in existing operations. For permanent installations, the systems can be mounted alongside the electrical distribution panels. Or, if the system is to be operated at several different sites with short commissioning and decommissioning times, the system can be supplied in a mobile cabinet, which provides greater flexibility of system placement.
Alongside the savings in diesel consumption and the reduction in CO2 and No2 emissions, hybrid systems also provide the following benefits:
- Up to a 90% reduction in noise pollution, due to the batteries silently powering the loads.
- Increased longevity of the generator and a reduction in servicing and costs.
- Reduction in costs associated with fuel logistics and delivery.
- Early warning of generator failures or electrical issues within the powered loads.
- 24/7 power for sensors, CCTV, monitoring, lights, etc.
- Access to live data on the systems status via AquaStat IoT.
The real-time monitoring platform (AquaStat IoT) has offered an insight into the farm’s power use profile and given the company scope to manage that even better. This level of monitoring of our power use is something we wouldn’t have had otherwise. Aside from the direct benefits, there are a lot of other things we can learn.
Frequently Asked Questions
To consider the total environmental impact of hybrid systems, the CO2 emissions offset when in use need to be balanced against the CO2 emissions produced in the manufacturing stage. Typically, 1kWh of lithium produces 73kG of CO2e at the manufacturing stage.
To achieve a CO2 net gain, it is critical that hybrid systems are correctly configured to ensure that the emissions produced in manufacturing are offset within the anticipated lifespan of the system. Incorrect configuration can lead to battery arrays reaching their end-of-life before offsetting their own carbon impact in production. CO2 emissions produced within the manufacturing stages are rarely integrated into the analysis and configuration of hybrid systems and can lead to a false understanding of success, due to the emission reduction when in use only being considered.
Aqua Power Technologies integrates hybrid systems considering the total life cycle analysis of emissions, not just the emission metrics when in use.
- Integrated brands include Siemens, Schneider, Omron, ABB.
- OEM warranties ranging between 3-5 years, depending on specification.
Depending on the power profile and budget, a range of battery technologies can be integrated, ranging from flooded lead acid to lithium iron to saltwater. In any situation, the battery charge and discharge parameters recommended by the manufacturer are strictly adhered to, which ensures the warranty and maximum useable power can be extracted from the battery over its lifetime.
- Integrated brands include Samsung NMC, Rolls, Valence, Tesla.
- OEM warranties ranging between 3-10 years, depending on specification.
Maintenance & Servicing
As a byproduct of integrating a hybrid system, the servicing and maintenance costs required for the generator system reduce, due to the significant reduction in generator on time.
The constant stream of data provides the opportunity for customers to obtain a deep insight into their power usage over time, which can be useful to retrospectively assess the effectiveness of operations and provides the opportunity to effectively implement change to achieve efficiency gains.
Aqua Power Technologies wave energy converter, MANTA, is specifically designed to operate with hybrid systems, and provides the opportunity for wave energy to power ocean based industrial sites, such as aquaculture.
