HVO Carbon Savings: Real Results from Temporary Power
In 2024, MEMS Power Generation supported customers in reducing carbon emissions by switching from diesel to Hydrotreated Vegetable Oil (HVO) for temporary generator hire. We delivered over 214,000 litres of HVO, cutting emissions and providing measurable carbon savings. That’s the equivalent of 428,000 standard 500ml water bottles, enough to give two bottles to every person in Greater Manchester. A clear example of how small changes at scale can deliver real impact.
Why HVO?
HVO is produced entirely from 100% renewable raw materials sourced from waste and residues such as vegetable oils and animal fats. It offers significantly lower lifecycle emissions than traditional diesel and can be used as a direct replacement in diesel generators, with no engine modifications needed.
This makes it a practical and future-aware fuel option for customers seeking low-impact solutions that do not compromise reliability.
Verified Emissions Data (kg CO₂e per litre)
| Fuel Type | Emissions (kg CO₂e/litre) |
| Diesel (average biofuel blend): | 2.47960 |
| HVO: | 0.03558 |
( Saving per litre switched to HVO: 2.47960 – 0.03558 = 2.44402 kg CO₂e )
2024 Delivery & Carbon Impact
| Metric | Value |
| HVO delivered in 2024: | 214,014 litres |
| CO₂e saved per litre: | 2.44402 kg |
| Total CO₂e saved: | 522,933 kg (≈ 523 tonnes) |
By switching to HVO, our customers avoided releasing 523 tonnes of CO₂e into the atmosphere in 2024. That’s from HVO alone, a clear example of how emissions can be reduced without changing how power is delivered.
What This Means
Saving 523 tonnes of CO₂e in 2024 is equivalent to:
-
-
-
Powering 147 UK homes for a year (based on average UK household energy use).
-
Driving 1.3 million miles in a typical petrol car.
-
Charging over 63 million smartphones.
-
Flying 524 passengers roundtrip from London to New York.
- Planting 8,700 tree seedlings and letting them grow for 10 years
-
-
These HVO carbon savings demonstrate the real-world environmental impact of switching from diesel to Hydrotreated Vegetable Oil across temporary power deployments.
Why It Matters
Power reliability remains non-negotiable for our customers. But now, so is environmental responsibility. By prioritising HVO where possible, MEMS helps businesses meet their sustainability targets without compromising performance.
Our Ongoing Approach to Reducing Impact
-
-
- Fuel switching to lower-emission alternatives like HVO
- Upgrading to Stage V generators
- Investing in logistics and delivery efficiency
- Customising deployments based on site requirements
-
What’s Next?
We will continue to report on our carbon savings annually, backed by the latest conversion data and delivery volumes. Our HVO carbon savings, Cleaner Options, and low-emission technology investments reflect a practical approach to sustainability.
Temporary power doesn’t have to come at the cost of environmental impact. MEMS Power Generation takes a practical, data-led approach to sustainability. From fleet upgrades to fuel switching, we focus on delivering real reductions in carbon emissions across every part of our operation, not just for ourselves, but for every customer we support.
Additional Ways MEMS Helps Reduce Your Carbon Footprint
At MEMS, sustainability is built into every aspect of our service. Beyond HVO, we offer a suite of solutions under our Cleaner Options initiative that help reduce emissions, cut fuel use and improve efficiency.
Our Cleaner Options range includes advanced technologies designed to support lower-impact power generation across all sectors. This includes Stage V generators, Battery Energy Storage Systems, and Load on Demand configurations, all selected to reduce environmental impact without compromising performance.
Stage V Generators
These generators comply with the latest UK and EU emission standards, significantly lowering emissions of nitrogen oxides (NOx), particulate matter (PM), and carbon monoxide (CO). Ideal for operations needing low-emission equipment that still delivers.
Battery Energy Storage Systems
Our battery systems reduce CO₂e emissions by lowering generator runtime. They also offer silent operation, making them suitable for sensitive environments. When combined with generators, they help deliver optimised and efficient power.
Load on Demand
Load on Demand systems match generator output to actual site demand. This prevents overgeneration, reduces unnecessary fuel burn, and drives down overall emissions.
