Components, such as sealing, wires and cables, and protective (conformal) coating, are used in conventional energy generation (e.g., thermal or nuclear power plants, industrial heat generation). Some examples of conventional energy applications are:

As dielectric layer in high performance communication cables and connectors used in nuclear research and production and in the hydrogen market.   As primary insulation and jacketing on electrical cables used in power generation, e.g., in gas turbines, transformers and batteries. This can also include cables used in control rooms and as sensor cables in nuclear plants.   In pump elements, injectors and injection holders for marine, locomotive and stationary power generation   In heat exchanger tubing in power plants   In general, various sealing components, such as gaskets, O-rings and seals are used in large power generation installations, e.g., in steam turbines.   As binders in lithium primary and secondary batteries for various long-term applications. Fluoropolymer solutions are also part of the chemistry of Li-ion cells and lithium primary battery cells. Those batteries can be found in diverse applications, such as metering, tracking, alarm systems, medical devices and aerospace.   Insulation discs in Li-ion batteries also use glass fabric coated with PTFE as an industry standard, due to the chemical, electrochemical and thermal stability of the PTFE and the additional stabilization of the glass fibre. This is a critical safety application for users such as medical devices and aerospace.   Everflon™ Fluoropolymer membranes are used in flow batteries. These are electrochemical devices used to store electricity in liquid electrolytes that are stored in tanks and pumped through the cell in charge and discharge cycles. The ion exchange membrane allows the transfer of ions between the anode and cathode of the cell, providing ionic resistance, mechanical properties, durability, and chemical stability.

Protective coating and other structural components in renewable energy sources:

Solar panel front sheet laminates for lightweight and flexible photovoltaics. Also as back sheet layer of full sheet for bifacial photovoltaic panels.   Perfluorinated ionomers can be used as an organic passivation layer for crystalline silicon heterojunction (HJN) and tunnel oxide passivated contact (TOPCON) n-type solar cells. Solar PV market industry is dominated by crystalline silicon and the technology trend is towards n-type HJN or TOPCON solar cell technology.   Offshore wind turbine installations also need components that can withstand harsh conditions, such as saltwater and the presence of oil. Such components can be cable insulation and sleeving and microswitches.   Wind turbine blades often use a Everflon™ fluoropolymer coating. Furthermore, wind turbine base bearings may be made of or be coated by fluoropolymers (primarily PTFE).

The emerging hydrogen technologies rely heavily on fluoropolymers, including membranes used in electrolysis (proton exchange membranes – PEM, alkaline electrolysers – AEL, anionic exchange membrane electrolysers – AEMEL), compressors used in biomass gasification and biogas or methane reforming, as well as in hydrogen storage and transport applications (valves, sealing and pipes). More specifically, applications of fluoropolymers in hydrogen technologies include:

As membrane in Membrane Electrode Assembly (MEA), as binder material, bipolar plates, ionomer and membrane support in proton exchange membrane electrolyser (PEMEL) stacks, gas drying units in H2 conditioning, electrolyte pumps and valves in a PEMEL system.   As seals, membranes, diaphragms in AEL stacks and gas drying units in H2 conditioning, electrolyte pumps and valves in an AEL system.   As membrane in MEA in AEMEL stacks, as membrane ionomer, cell frames and seals in stacks and also in the gas drying unit.   In air or oxygen compression units and CO2 separation units used in biogas or methane reforming and biomass or waste gasification units.   In several applications in storage (compressed or storage) and transport of gaseous and liquid hydrogen. Fluoropolymers can be used as liners of pressurised cylinders, as pipe seals and fittings, as sealing in hydrogenation and dehydrogenation systems, in pumps, in transfer arms in liquid hydrogen transfer systems, etc.   Membranes, ionomer, membrane support in PEM fuel cell (PEMFC) MEA; ionomer in PEMFC catalyst layer; Gas diffusion layer (GDL), bipolar plates and seals in PEMFC stack; diaphragms and seals in liquid pumps.   As components and sealing in turbines, burners and boilers using hydrogen fuel.
