Building a bridge between energy networks

The expansion of electric mobility and increased generation and use of wind and solar energy represent important steps forward – but they do not add up to a true revolution in the energy sector. The reason is that only a quarter of the energy we consume takes the form of electricity. A bridge between the energy, mobility and gas/heat supply sectors is therefore required if we are to make renewable energies a familiar part of everyday life.

Sunfire’s Reversible Solid Oxide Cell (RSOC) makes it possible to bridge the gap between the energy sector and the chemicals and fuel sector. It unites a fuel cell and electrolyser in a single system and turns wind and solar energy into green hydrogen ready for conversion into chemicals and fuels by industrial companies and refineries. The RSOC also offers the added benefit of a fuel cell mode: If the electricity grid experiences a sudden spike in demand, it takes just a few minutes to switch over to fuel cell mode and use the RSOC to generate electricity.

Renewable energy everywhere

In addition to producing hydrogen with the aid of wind and solar energy, Sunfire’s technology is also able to recycle atmospheric CO2. The subsequent combination of recycled CO2 with renewable hydrogen yields synthetic crude oil – and with it, a basis for all fuels and chemical products. The resultant fuels and products represent an opportunity to increase the environmental friendliness of not only long-distance road transport, aviation and shipping, but also everyday consumer products. What would be a huge step forward is nevertheless dependent on the creation of a political framework, which supports the profitable large-scale production of synthetic fuels.

Reversible electrolysis – the key to expand energy transition

The flexible Sunfire system already paves the way for substantial increases in the proportion of renewable energy within the overall energy system and ensures that wind and solar energy always flow to where they are needed most.
