Accelerating Electrification in the Energy & Industrial Sectors with HeatPower

Electrification has been hailed as ‘one of the most important strategies for reducing CO2 emissions from energy’ (IEA, 2023), but will it deliver the environmental impact we need to achieve global net-zero targets and be a cost-efficient method of decarbonization?

Replacing processes and technologies that use fossil fuels, such as coal or gas, with electrically powered alternatives may seem like an obvious and easy way to mitigate the climate crisis but the success of electrification relies on two critical segments:

  • Power producers
  • Large-scale electricity consumers

In this article, we take a closer look at how energy companies and energy-intensive industries can embrace – and facilitate – electrification to achieve worldwide emissions reductions and accelerate the switch to a more stable and sustainable energy infrastructure.

Power Producers: Facilitating Electrification

As we transition to electrically powered technologies and processes, the demand for electricity will increase considerably (Enerdata, 2024). In response, energy companies will need to deliver higher power outputs. However, energy production remains a major contributor of global CO2 emissions:

To ensure electrification delivers maximum environmental benefits, it’s essential that power producers increase sustainable electricity outputs and make green energy easily accessible and cost-efficient.

The uptake in renewables is already predicted to fulfil the short-term increased demand for electricity (IEA, 2024) but the non-dispatchable, weather-dependent nature of major renewables mean they are not a cure-all for decarbonizing the energy sector. Instead, a combination of sustainable technologies is required to deliver the environmental, practical and economic benefits that are needed to facilitate a cost-effective and reliable energy transition.

For example, Climeon’s HeatPower 300 technology converts low-temperature waste heat generated via the production process into clean, dispatchable and weather-independent electricity.

This complements and safeguards the existing renewable mix while enabling energy companies to increase sustainable power outputs and enhance energy efficiency.

Low-Temp Waste Heat Recovery in the Energy Sector

Today’s energy sector is more diverse than ever before. From major utility companies to independent renewable producers, there are a variety of options when it comes to generating or sourcing power.

However, most methods of electricity production generate waste heat and a considerable proportion of this waste heat is produced at low temperatures. This means Climeon's HeatPower 300 systems can be deployed at a range of different types of power plants.

Using waste heat at temperatures as low as 80°C, a cold input source and an environmentally friendly working media, HeatPower 300 employs an Organic Rankine Cycle (ORC) to convert this heat into sustainable electricity. Our innovative technology is designed to enhance the cost-efficiency of clean electricity derived from low-temp waste heat sources, such as jacket cooling water.

When HeatPower 300 is integrated into power stations and plants, it enables energy producers to boost sustainable power outputs, lower operating costs and reduce emissions via:

  • Competitive payback periods
  • Uncomplicated installations
  • Dispatchability
  • Robust construction
  • Weather independence
  • Minimal maintenance requirements
  • Market-leading low-temp conversion efficiency

Crucially, HeatPower 300 enables energy companies to increase clean energy outputs in time to meet the enhanced demand for green electricity. As electrification intensifies, energy producers can rely on Climeon’s HeatPower 300 technology to help facilitate a successful and cost-efficient transition.

Example: Combustion Engine Power Plants

At combustion engine power plants, for example, the waste heat that’s generated via cooling streams and exhaust gases can be used as an input source for HeatPower 300 units. Crucially, this boosts the plants sustainable electricity output, as well as increasing the total power output.

Example: Biogas Power Plants

HeatPower 300 systems can be deployed at biogas power plants to leverage the low-temp waste heat that’s present in the cooling water system that operates alongside the gas engines that facilitate fermentation. By utilizing this heat and converting it into clean, usable electricity, biogas plants can benefit from enhanced energy efficiency and increased outputs, thus optimizing profitability.

Energy Consumers: Generating and Utilizing Clean Electricity

On a global scale, the industrial sector accounts for the largest consumption of energy yet it remains heavily reliant on fossil fuels and is failing to hit key net-zero targets (IEA, 2023).

Industrial electrification may be underway but a faster transition to electrically powered technologies, machinery and processes could significantly reduce industrial CO2 emissions.

If energy companies and power producers succeed in increasing the availability and cost-efficiency of green electricity, industrial companies can accelerate electrification and decarbonization by choosing to purchase clean electricity from the grid but this isn’t the only way to speed up electrification across the sector.

Many industrial processes generate waste heat, and this can be used to produce on-site sustainable electricity. High-temperature waste heat recovery (WHR) has been used in industrial settings for some time but, until now, low-temperature WHR has not been seen as a cost-efficient source of power.

However, Climeon’s innovative technology means that industrial low-temp WHR is now a cost-effective way for energy-intensive industries to reduce CO2 emissions. As low-temp waste heat is repurposed into clean electricity, industrial firms can generate more power from the original energy source, thus increasing energy efficiency and lowering energy costs.

By generating clean, on-site electricity, industrial businesses are also less reliant on the grid and less vulnerable to the volatility of the energy market.

As the recent energy crisis showed, domestic power production and improved energy stability are critical to maintaining a reliable and profitable global industrial infrastructure (IMO, 2022). With HeatPower 300, industrial companies can safeguard access to clean electricity at a low cost-per-kilowatt while cutting emissions and reducing energy costs.

This combination of economic and environmental benefits makes Climeon’s low-temp WHR system an ideal choice for energy-intensive industrial sub-sectors as they face increasing pressure to decarbonize.

Example: Industrial WHR at Steel Manufacturing Plants

Steel manufacturing produces a vast amount of heat but the low temperature waste heat that is generated during the production process is often overlooked. At SSAB, forward-thinking leaders were quick to recognize the value of low-temp waste heat when they integrated Climeon’s HeatPower technology at their plant in Borlänge, Sweden.

Using waste heat from the reheating furnace and continuous annealing line, along with cold water from the nearby Dal River, HeatPower ensures that low-temp process heat doesn’t go to waste. Operational since 2015, the HeatPower system continues to deliver clean, on-site electricity to power the site’s internal operations and supports SSAB's goal of eliminating all CO2 emissions by 2045.

Example: Low-Temp WHR for PET Resins and Polyol Production

Just last year, Engineering, Procurement and Construction (EPC) firm, UAB Termolink, selected Climeon’s HeatPower 300 system for integration at NEO GROUP’s PET Resins and Polyol plant in Klaipeda, Lithuania.

Here, the HeatPower 300 system will use excess steam generated when ethylene glycol and terephthalic acid are merged to produce PET resins as a hot input source. With the installation already underway, NEO GROUP will be producing on-site sustainable electricity with Climeon’s HeatPower 300 technology within a matter of weeks.

Boosting Outputs and Increasing Access to Sustainable Electricity

Despite the complexities associated with decarbonization, innovative cleantech solutions are already helping to reduce the CO2 intensity of electricity production and, by applying the right combination of technologies, we can successfully cut carbon emissions further.

Climeon’s low-temp WHR system allows us to take a two-pronged approach – enabling both power producers and energy consumers to generate sustainable electricity that can be used on site and/or added to the grid.

This not only accelerates electrification; it helps ensure that the increased demand for electricity comes from sustainable sources with no CO2 emissions being added to the mix. In turn, energy companies, independent producers and energy-intensive consumers can reduce their carbon footprint, increase energy efficiency and access clean, dispatchable electricity on demand.
