For a more sustainable world.

The world is evolving, as is the power rental market. We all work together for a more sustainable world. Energyst contributes to this as well. Vast amounts of energy and fuel are consumed, and unwelcome bi-products created, across the industries in which we operate.
We feel responsible to make a difference. We do so by always considering the following three opportunities; power management and selection of energy source to decrease the fuel consumption, to make use of alternative fuels and/or by adding ‘after treatment solutions’ to improve emissions.

Whatever your challenge is, we always strive to invent the best solution for you, keeping in mind the balance between sustainability, reliability and your economical situation.

On this page you can read about opportunities and examples on how to operate in a more environmentally friendly way.

SUSTAINABLE PRACTICES

Power Management

The first step we take to contribute, is to select the correct size of generator to make sure the engine runs most efficient and less fuel is being burned. When the application exists of 2 or more generators, we can get more creative in power management. We can apply:
– Load on demand, the generators are used based on your power use. Therefore, the engine runs less, drastically reducing emissions for the lifetime of your project.
– Load sharing and fuel optimization, where we sync generators to limit inefficiencies in the engines performance while monitoring the daily power demand.

In addition to syncing the generators, we can then include energy storage units (batteries) in the application. The energy storage unit is programmed to monitor your power demand and only use the generator to boost or charge when necessary. Together they provide the optimal power solution.

HVO AND GTL VS DIESEL

With an increasing focus on the environment and the reduction of different exhaust gases, oil companies are looking for fuels that can meet these requirements. Both HVO (Hydrotreated Vegetable Oil) and GTL (Gas-To-Liquid) are fuels that are more environmentally friendly compared to diesel. And we are excited to share that both can be used to run our entire range of machines as a direct replacement to diesel.

HVO and GTL ensure less Particulate Matter (PM), Nitrogen and Sulfur Oxides emissions. Because HVO is produced from biomass, therefore it is synthetic and not to be confused with ‘Biodiesel’, less CO2 is used in the production process. With the use of 100% HVO, this difference can even amount to 89% CO2 savings. This advantage does not occur with GTL, which is produced from natural gas.

We are performing research and tests to analyse on exact emission reductions whilst running our machines under various circumstances. We are looking forward to share the outcomes with you!

Fuel efficiency and reduction not only make dramatic savings on operational costs, but also Carbon footprint!

Use of Selective Catalytic Reduction (SCR) and Diesel Particle Filter (DPF)

Are you looking for a temporary power supply with low NOx emissions up to 90% to get in line with local legislations? We can provide generator sets with additional Selective Catalytic Reduction (SCR) and Diesel Particle Filter (DPF) to lower the NOx and Soot to the required levels. Furthermore, by injecting Adblue into the generators exhaust, we can reduce CO2 and NOx even further.

Full electrical solution at Berlin Airport

Flughafen Berlin Schönefeld urgently required additional capacity to cope with the growing number of visitors. Neptunus was appointed to deliver a temporary terminal, including a heating and air conditioning system which could produce a year-round room temperature of 21°C. Preferably, without using any fossil fuels due to the airport’s green ambitions. And that’s exactly where our expertise comes in.

Together with #Neptunus and by bringing our #RealEnergy we designed a fully electrical solution which supplies air conditioning during hot summer periods and enough heating capacity during the winter season. Our 300 kW heatpumps were extended with 80 kW electrical heating capacity, all fully PLC controlled. Resulting in a comfortable and automatically operating climate for all passengers.

Reduced fire risk of transformers

Energyst has a fleet of 8 MVA transformers which are designed with a reduced fire risk because we choose to use Biodegradable Synthetic Ester fluid. If you are interested in learning how we achieve this, just contact any Energyst office for more information.

The most energy efficient chillers

We offer EC500 and EC800 air-cooled chillers, which are the most energy efficient chillers available on the rental market today, with an optimal balance between footprint and refrigerant. The sound levels and electrical power-input to start and during operation are lower than most other rental-chillers.

Reliable and efficient cooling towers

Our cooling towers have a design capacity of approx. 2MW. The units are used to cool down your process water within a wide range of water and ambient air temperatures.

Cooling towers use the principle of ambient air to cool down process water. With a minimum use of power and a high cooling capacity it is a cost and energy efficient solution.

Air-to-air Heat Pumps

Our air-to-air heat pumps have a capacity of 50KW. These units offer an all-electric solution to condition the climate in your (temporary) location. Their compact design ensures an optimal flexibility with both a heating and cooling function.

The plug & play units work with the greenest refrigerant available in the market right now (R32). They are equipped with automatic controls which can support you with, for example, CO2 monitoring and control.

ADDITIONAL ACTIVITIES

The impact of fuel on our immediate environment

On our Group services yard we only use GTL fuel to test our equipment instead of conventional diesel. This prevents unpleasant smells and black smoke, so the inconvenience for our direct neighbors is reduced to a minimum and harmful emissions are reduced significantly.

Energyst is exploring the possibility of rolling this out across our entire network of depots.

Here you can see the difference between Diesel on the left and GTL on the right, with less smoke and smell. Do you want to discuss how we can be environmental conscience together? Contact us!

DEPOTS

Energyst encourages all its employees to run the business in a more environmentally sound and more sustainable manner. Therefor Energyst is ISO14001 certified. All depots are looking ways to improve their environmental performance and reduce impact on the environment.

This certification is recognised worldwide. At Energyst we are committed to reducing our environmental impact and meeting sustainability expectations and achieve this by continuously improving our environmental management system. Read more about our certifications.

LEASE CAR POLICY

Corporate social responsibility is one of our top priorities. We aim to make our company car fleet ‘greener’. The car choice is therefore limited to energy-efficient cars: cars with energy label A, B or C, with a preference for a car that is as energy-efficient as possible.

Employees that choose a car with an A or B energy level, receive a ‘green’ premium. If the car is not electrical, the standard fuel is petrol. In some countries natural gas / bi fuel / or hybrid cars are considered as an alternative.

SUPPLIERS

Many countries in Europe have committed to reducing their carbon emissions and Greenhouse Gases. This is the same for our suppliers who manage to embrace environmental sustainability. For example, we positively welcome our fuel suppliers who have a strategic policy for providing quality fuels that help reduce the impact on the environment from harmful exhaust emissions. They do this at source and are active in carbon offsetting operationally via their transport delivery fleet based on delivery mileage.

EXPLORING MORE AND MORE OPPORTUNITIES

We try to investigate every possible opportunity to work more sustainable. An option that we are currently exploring is the use of biogas in our generators. Also, we have developed applications which make use of the district heating network instead of connecting heating equipment that runs on diesel. Which means no use of fossil fuels!

If you have an environmental conscience and you feel strongly about making a difference to your carbon footprint, speak to our technical teams with what is important to you and we will demonstrate a way of helping you achieve it.
