South Africa: Solar Green Beer Production Creates High IRR

Submitted by Baerbel Epp on September 14, 2016
CBC Installation South AfricaSouth Africa’s solar process heat installations remain profitable when they have to compete against other heat sources, such as diesel, paraffin, petrol or gas, the Centre for Renewable and Sustainable Energy Studies (CRSES) at Stellenbosch University, South Africa, has concluded in a recently published paper. The researchers at the CRSES conducted a feasibility study of a 120.7 m² collector field that was to cover 60 % of the existing hot water requirements of Cape Brewing Company (CBC) based in Suider-Paarl, Western Cape, and analysed ten proposals submitted after the company’s invitation to tender in January 2015. South African E3 Energy won by offering an installation with a levelised cost of energy of 7.9 EUR cents/kWh, an internal rate of return of 16.7 % and a payback period of 9.3 years. CBC´s daily hot water demand is estimated to be 7,000 litres at 85 °C during 245 days a year, i.e., during a full year except for weekends, public holidays and two weeks of summer holidays. The system went into operation in November 2015 and the COO of CBC, Andy Kung, seems satisfied with the performance and the energy saving it offers.

Solar Process Heat in Breweries (2014)

Submitted by Raquel Ponte Costa on February 13, 2015

This presentation was given by AEE INTEC at a SOLTRAIN training in Pretoria, South Africa, in April 2014.  It provides an overview of the EU-funded FP7 project SolarBrew.  This project aims at developing the use of solar process heat in the brewing industry. 3 breweries are part of this project.  The Brewery Goess in Austria is using solar energy for its mashing process, relying on a 1.500m² flat plate collector field and a 200m³ storage tank.

Brewing Beer with Solar Heat (2010)

Submitted by Raquel Ponte Costa on August 10, 2012

This report gives case studies of two Germany beer breweries - the Hofmühl brewery in Eichstätt and the Hüth Brewiry in Kassel-Baunatal - that have integrated solar thermal energy into their production process. Although there is high potential for solar process heat to be used in industrial applications, the necessary technology remains relatively expensive when operating temperatures exceed 100°C, meaning that its penetration remains low.

Europe: Heineken Brewery to Install Three Big Solar Plants

Submitted by Baerbel Epp on April 18, 2012

 Heinecken brewery The famous beer brand Heineken has just placed an order for three big solar thermal plants that will produce the heat required for the brewery’s industrial processes at different company sites. Two of these systems will be installed at breweries – one in Valencia, Spain, and one in Göß, Austria - and one will be set up at a malting plant in Vialonga, Portugal. The photo shows beer bottles on their way into the tunnel pasteuriser at the Valencia brewery.
