Ripasso Energy signs South African sales agreement

The Swedish cleantech company Ripasso Energy AB signed an agreement today with the South African ferrochrome producer Afarak Mogale (Pty) Ltd for the sale of 7 PWR BLOK 400-F’s. The order value is €3,766,000, with a delivery time of 12 months.

In September 2017, Ripasso Energy launched the PWR BLOK 400-F, a container-based solution in which the company’s Stirling engine is used to harness energy from residual gas combustion. The first sales agreement has now been signed, just three months after product launch. The buyer is the South African ferrochrome producer Afarak Mogale (Pty) Ltd. Afarak is part of the Afarak Group – a global manufacturer of specialty alloys with operations in South Africa, Turkey, Germany, London, Helsinki and Malta. The Afarak Group stock is traded on the London Stock Exchange, as well as on the NASDAQ OMX Helsinki. 

“Not only does this mark a major success for Ripasso Energy and show that we were right to invest in the PWR BLOK, but above all it provides very concrete evidence that Stirling technology can play a very significant role in the future generation of climate-friendly energy,” says Gunnar Larsson, CEO of Ripasso Energy

The deal is for the purchase of 7 PWR BLOK’s with a total of 98 Stirling engines that Ripasso Energy will deliver to Afarak within 12 months. The sale includes a credit and a repurchase clause that at the earliest may be utilised 36 months after the signature date and for a period of 18 months thereafter, entailing that Ripasso Energy repurchases the product at a price equivalent to Afarak’s acquisition cost, less the cost savings realised between initial delivery and the time of repurchase. These cost savings are calculated to yield a customer payback period of three and a half years.

“The sale of the PWR BLOK’s to Afarak, along with the agreement signed in May with the Italian company Horizon for the sale of solar hybrid systems, means that Ripasso Energy’s objectives are proceeding according to plan. We are very positive about the future,” says Sven Sahle, Ripasso Energy’s Chairman of the Board.
