Ahead of the curve in the green trans­ition

“The climate crisis and the energy revolu­tion chal­lenge both the energy tech­no­logy sector and com­pan­ies in general to improve their own busi­ness. Oilon stands at the fore­front of this change.”

Our climate is chan­ging, and with it, the rules and prin­ciples of busi­ness. Legis­lat­ors, investors, and con­sumers demand com­pan­ies to go green, and using big words is no longer enough.

In some com­pan­ies, this trans­ition causes con­cerns, and in others, it is seen as an oppor­tun­ity. Then there are the pion­eers, such as Oilon, who are willing to stand at the fore­front of the change. The company, which cel­eb­rated its 60th anniversary in spring 2021, has inves­ted in sus­tain­able devel­op­ment for decades.

“A good example is the nitro­gen oxides in burners. We’ve managed to reduce NOx emis­sions by 80–90 per cent in ten years,” says Oilon’s CEO Tero Tulokas with a hint of pride in his voice. After all, nitro­gen oxides are among the most harmful atmo­spheric emis­sions from energy pro­duc­tion.

This quantum leap in emis­sion reduc­tion was made pos­sible by digital twins. These are exact virtual models that allow Oilon’s experts to improve product per­form­ance at a fast pace, as fewer phys­ical pro­to­types are required for testing. Virtual twins are also used for burner and heat pump mon­it­or­ing and optim­iz­a­tion.

Extend­ing the range of com­pat­ible fuels has been another key focus in product devel­op­ment. Cur­rently, Oilon burners can fire prac­tic­ally any of the known bio­fuels.

“Bio­gases, bio-​oils, ethanol, meth­anol – we can use any liquid and gaseous fuel avail­able”, Tulokas says. One of the fuels on the list is green hydro­gen, which is believed to have huge poten­tial.

One million tonnes of CO2 elim­in­ated

When cal­cu­lat­ing carbon dioxide emis­sions for energy pro­duc­tion, the biggest factor is fuel choice. However, there is another effect­ive way of improv­ing emis­sion levels: increas­ing the burners’ adjust­ment range.

“The smaller the part load at which the burner can operate, the fewer fuel-​hungry boiler starts and stops there are,” Tulokas explains. For instance, being able to con­tinue firing at 10% load instead of 25% makes a massive dif­fer­ence. Increas­ing the burner’s control range can decrease fuel con­sump­tion by more than 10 per cent.

Another way to reduce fuel con­sump­tion is to reduce resid­ual oxygen content in flue gas, res­ult­ing in reduced CO2 emis­sions. The smaller the resid­ual oxygen content after com­bus­tion, the less energy is wasted. Thanks to intens­ive research and devel­op­ment, Oilon has managed to achieve increas­ingly lower resid­ual oxygen levels.

In Oilon burners, com­bus­tion is managed by an auto­mated system which optim­izes the ratio between fuel and oxygen.

The reduc­tion in CO2 emis­sions exper­i­enced by Oilon’s burner cus­tom­ers is often dra­matic.

“When an energy company from Beijing switched from coal to natural gas and Oilon burners, the company’s CO2 emis­sions were reduced by around one million tonnes per year. This cor­res­ponds to around 10 per cent of Finland’s trans­port emis­sions,” Tulokas says.

Energy com­pan­ies embrace heat pumps

In inter­na­tional scen­arios, heat pumps have been iden­ti­fied as one of the primary solu­tions for redu­cing green­house gas emis­sions. For example, the Inter­na­tional Energy Agency believes that by 2045, as much as half of the energy required for build­ing heating should be covered by heat pumps. This is due to climate goals – after all, heat pumps are very effi­cient in util­iz­ing renew­able thermal energy from sources such as soil and outdoor air.

“For years now, Oilon has inves­ted heavily in heat pump product devel­op­ment. We can already reach tem­per­at­ures of 120–130 °C, an inter­est­ing pro­pos­i­tion espe­cially for indus­trial cus­tom­ers,” Tulokas says.

One of the focal points in heat pump research is the coef­fi­cient of per­form­ance, COP. It conveys how effi­ciently the heat pump trans­forms elec­tri­city into energy.

“When pro­du­cing heating and cooling at the same time, we can produce up to 10 kilo­watts of energy per one kilo­watt of elec­tri­city,” Tulokas says. In ground source cooling, the COP can be as high as 20–30.

In indus­trial applic­a­tions, Oilon heat pumps are typ­ic­ally used for recyc­ling energy. What this means in prac­tice is that waste energy from one machine or process is recovered and reused else­where with a good COP.

Oilon has a wide variety of cus­tom­ers around the world. Data centers, wastewa­ter treat­ment plants, dairies, food pro­cessing plants, and chem­ical industry oper­at­ors all use Oilon heat pumps.

Com­pan­ies oper­at­ing in the energy sector are espe­cially inter­ested in carbon-​neutral heat pro­duc­tion. One reason for this is emis­sions trading, which encour­ages com­pan­ies to switch away from fossil energy sources. The Finnish energy company Fortum is a good example. The company has pro­cured Oilon heat pumps which will replace coal-​based heating in Espoo.

If the entire 11-MW scope of the project is com­pleted, the system will replace around 92 gigawatt hours of coal energy. This cor­res­ponds to 31,000 tonnes of CO2 per year or remov­ing 14,500 cars from Finnish roads.

Walking the talk

For several years, Oilon has worked act­ively towards redu­cing the company’s own carbon foot­print. Ground source heating is used where pos­sible, factory roofs are now peppered with solar panels, and there have been energy system upgrades at Oilon prop­er­ties.

In the fall of 2021, Oilon joined the Science Based Targets ini­ti­at­ive (SBTi), one of the most influ­en­tial climate ini­ti­at­ives for the private sector. Members commit to redu­cing emis­sions from their own oper­a­tions in line with the Paris Agree­ment’s goals.

Oilon has pledged that by 2030, the company will reduce both their direct and indir­ect green­house gas emis­sions by least 46 per cent from the 2019 levels. At the current rate, this goal will be reached ahead of time.

“Nearly 3,000 pion­eer­ing com­pan­ies have joined the ini­ti­at­ive. This is an excel­lent way to promote both internal climate goals and exer­cise cor­por­ate respons­ib­il­ity,” Tulokas says.

Even though envir­on­mental respons­ib­il­ity is a key part of Oilon’s busi­ness DNA, it is equally import­ant to develop our eco­nom­ical and social respons­ib­il­ity. “A three-​legged stool will always be more stable,” Tulokas sums up.
