With so many of our customers now putting decarbonization at the heart of their operations, we’ve made it a priority to develop new technologies and partnerships that accelerate their moves in this direction. Let’s take a look.
Decarbonization is the main megatrend shaping our industry, while at the same time grids are becoming increasingly digitized and decentralized. This changing landscape is driving SFW to explore and innovate in energy generation, electrical and heat storage, carbon capture, the circular economy and more – all the areas that can help our customers transform their business.
Key to these efforts is the Innovation Program we established in 2018. It’s a dedicated forum that brings together people from across the company to work on challenges faced by our customers. The program has led to several new concepts and partnerships that diversify our portfolio.
Principal Engineer Eero Halikka manages the Innovation Program’s energy track. Halikka has worked in the Technology and R&D department at SFW and its predecessor for more than 20 years, so he’s been part of the industry’s shift towards decarbonization from the start.
Energy storage takes a center stage
Many of the ideas coming out of the Innovation Program are in the area of energy storage. Through discussions with customers, SFW has identified two main industry challenges that the program is addressing.
The first challenge is around the issue of storing energy so that grids can cope with the variability inherent in renewable energy. The sun does not always shine, and the wind does not always blow – so energy providers need efficient ways to store renewable energy that can be dispatched into the grid when needed. This capability brings more stability to grids as they increase their share of renewables.
The other challenge concerns co-generation plants that produce power as well as heat. These plants are increasingly looking for ways to store both, as this allows them more flexibility in switching their production balance from one to the other in response to market demand and price elasticity. This challenge has been getting even more attention recently with the wild up and down swings in electricity prices.
R&D and Patents Director Edgardo Coda Zabetta says the demand for innovation in heat storage is also coming from other industry sectors.
Going big on Long Duration Energy Storage
The Innovation Program is looking closely at the integration of Long Duration Energy Storage (LDES) with solutions that involve both power and heat, as well as that connect with the hydrogen economy.
SFW provides LDES through Liquified Air Energy Storage (LAES). The advantage with LAES is its ability to provide flexibility and stability in grids as renewables get added in a bid to achieve net-zero systems. The technology can also be integrated with other systems in the hydrogen economy.
SFW is now a leader in LAES thanks to a USD 46 million investment in the UK’s Highview Power. The investment is a direct result of work done in the Innovation Program.
Partnering in Sweden
For technology that’s optimized specifically to store heat, SFW is collaborating with Swedish energy-storage pioneer SaltX. The company has developed a thermo-chemical storage technique based on nanocoated salt. Charged salt can be moved from one location to another, which means that demand does not necessarily need to be met by production in the same location.
SFW is now working on a 100-kilowatt pilot with SaltX where the energy-storage medium is calcium oxide – commonly known as quicklime. When water is added to lime, then it becomes hydrated and releases lots of energy in a closed-loop cycle.
SFW also has work ongoing with the chemical looping of metal-oxides. With minimal modifications, existing plants that used to burn fossil fuels can be repurposed to burn iron, producing similar amounts of energy with no emissions. Renewable energy like solar and wind can then be used to return the burned iron back to iron – to be burned indefinitely.
SFW is always open to discussions on collaboration, partnership and co-creation opportunities. We welcome you to get in touch with us.
