The backup and standby power sector is undergoing a significant transformation. Since the European Renewable Energy Directive came into force (RED II, and subsequently RED III), corporate decarbonisation pressure has grown steadily. As a result, one question is appearing more and more frequently on the desks of technical and procurement managers: should we switch to HVO?<\/p>\n<p>HVO \u2014 <em>Hydrotreated Vegetable Oil<\/em> \u2014 is presented as a drop-in substitute for conventional diesel. In theory, you could empty the tank, fill it with HVO, and cut your <strong>HVO generator set<\/strong>&#8216;s carbon footprint by half \u2014 or even tenfold. In practice, however, the reality is somewhat more nuanced.<\/p>\n<p>This article offers a rigorous technical comparison between HVO and conventional diesel for generator set applications: engine performance, material compatibility, physicochemical properties, environmental impact, regulatory requirements and real costs. Ultimately, the goal is to give you the information you need to make an informed decision.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_What_is_HVO_Definition_and_production_process\"><\/span><strong>1.

Unlike first-generation biodiesel (FAME \u2013 <em>Fatty Acid Methyl Esters<\/em>), HVO does not result from transesterification, but from a hydrogenation reaction at high temperature and pressure that completely removes oxygen from the molecule.<\/p>\n<p>As a result, the product is a hydrocarbon <strong>chemically very close to mineral diesel<\/strong>, but with a more homogeneous and pure molecular structure. The industry standardises HVO through the <a href=\"https:\/\/www.une.org\/encuentra-tu-norma\/busca-tu-norma\/norma\/?c=N0057455\" target=\"_blank\" rel=\"noopener\">European standard <strong>EN 15940<\/strong><\/a> (paraffinic diesel), while conventional diesel complies with standard <strong>EN 590<\/strong>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Raw_materials_and_sustainability_hierarchy\"><\/span><strong>Raw materials and sustainability hierarchy<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In line with the <a href=\"https:\/\/eur-lex.europa.eu\/legal-content\/EN\/TXT\/?uri=CELEX:32023L2413\" target=\"_blank\" rel=\"noopener\">RED III framework (Directive 2023\/2413\/EU)<\/a>, the RED III framework classifies raw materials for HVO production according to their impact on land use:<\/p>\n<table width=\"567\">\n<thead>\n<tr>\n<td width=\"159\"><strong>Category<\/strong><\/td>\n<td width=\"238\"><strong>Examples<\/strong><\/td>\n<td width=\"170\"><strong>GHG emission factor<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td width=\"159\"><strong>Tier 1 \u2013 Waste and residues<\/strong><\/td>\n<td width=\"238\">Used cooking oils (UCO), category 1 &amp; 2 animal fats<\/td>\n<td width=\"170\">Reduction of up to 90% vs fossil diesel<\/td>\n<\/tr>\n<tr>\n<td width=\"159\"><strong>Tier 2 \u2013 Dedicated crops<\/strong><\/td>\n<td width=\"238\">Rapeseed, soybean, palm (controversial)<\/td>\n<td width=\"170\">Variable reduction, high ILUC risk<\/td>\n<\/tr>\n<tr>\n<td width=\"159\"><strong>Tier 3 \u2013 Agricultural residues<\/strong><\/td>\n<td width=\"238\">Tall oil, wood residues<\/td>\n<td width=\"170\">60\u201380% reduction<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><strong>Key warning:<\/strong> The carbon footprint of HVO can vary considerably depending on its raw material.

For a generator set used in automatic standby mode, this is a tangible advantage.<\/li>\n<li><strong>The lower heating value<\/strong> of HVO, on the other hand, means volumetric fuel consumption is approximately 3 to 6% higher to produce the same power output. In practice, a set consuming 10 L\/h on diesel will consume around 10.3 to 10.6 L\/h on HVO100. Tank range is slightly reduced.<\/li>\n<li><strong>The low aromatics content<\/strong> reduces the production of PAH (polycyclic aromatic hydrocarbons) and fine particles, resulting in cleaner combustion and less strain on DPF particulate filters.<\/li>\n<li><strong>The superior storage stability<\/strong>, finally, is a major advantage for standby generator sets, whose fuel can sit in the tank for extended periods without use. Conventional diesel degrades after 6 to 12 months (oxidation, deposit formation, microbial growth); HVO, free from unsaturated fatty acids, is far more stable.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"3_HVO_generator_set_compatibility_what_you_need_to_know\"><\/span><strong>3.

This effect is generally minimal but should be verified.<\/li>\n<li><strong>High-pressure injection systems<\/strong>: older injection pumps and injectors have lubrication tolerances designed for diesel EN 590. HVO has slightly lower lubricity (HFRR &lt; 460 \u00b5m per EN 15940), though HVO formulators can add lubricity improver additives.<\/li>\n<li><strong>Injection timing adjustment<\/strong>: the shorter ignition delay of HVO may slightly shift the optimal combustion point. On engines with fixed mechanical timing, this difference is generally insignificant.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"33_HVOdiesel_blends\"><\/span><strong>3.3 HVO\/diesel blends<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>HVO and diesel EN 590 are miscible in any proportion.

Nevertheless, it is a high-quality paraffinic fuel with engine performance equivalent to diesel. Its main advantage is a substantial reduction in lifecycle carbon footprint \u2014 provided the raw material is certified and traceable.<\/p>\n<p>For recent generator sets (Stage IV \/ Stage V), the transition to HVO100 or HVO\/diesel blends is technically sound and operationally viable. This holds for engines carrying official HVO approval from their manufacturer, with a few precautions during implementation.<\/p>\n<p>The decision to switch to HVO must take into account:<\/p>\n<ol>\n<li>Verification of engine approval with the manufacturer<\/li>\n<li>The origin and certification of the HVO procured (priority to ISCC-certified UCO)<\/li>\n<li>Analysis of the fuel cost premium against the expected regulatory and CSR benefits<\/li>\n<li>A preventive maintenance plan for the transition<\/li>\n<\/ol>\n<p>For fleets subject to CSRD, GHG Protocol Scope 1 reporting or internal carbon neutrality policies, HVO is today one of the most accessible levers available.
