Brazil´s enormous SHIP potential

Businesses which require large amounts of thermal energy below 400 °C can be found in several sectors, from beverage, chemical and food production to leather and textile making – the right kind of clientele for solar thermal suppliers. These are two of the key findings from the Solar Heat for Industry: Brazil study (see the attached document written in Portuguese), which was published this month as part of the Solar Payback project. It will be presented during the Solar Payback Conference, a half-day event scheduled to take place on 30 August at the Intersolar South America in Sao Paulo (see the attached flyer).

The authors of the study analysed data collected in Balanço Energético Nacional describing industrial energy flows and sources across the country (see also the pie chart below): 
  • Energy demand in the industrial sector is now almost twice as high as it was in 1990 and increased from 43.5 Mtoe to 84.2 Mtoe.
  • Heat dominates final energy consumption in industry, while demand for electricity has been fairly stable over the last 20 years, failing to exceed 20 %.
  • Industrial heat demand below 400 °C makes up 59 %, or 67.4 Mtoe, of the total and solar thermal technologies are an efficient means of meeting that demand.
  • Biomass provides 47 % of the thermal energy consumed in industry. An estimated 25 % of the firewood used as fuel is harvested locally, which means that deforestation is an issue that has not yet been resolved.
  • Over 80 % of the heat consumed in the sugar industry is produced from bagasse, which is why the sector is not nearly as relevant as others regarding the use of solar heat for industrial processes, also known as SHIP.

Despite the high potential for SHIP technologies in Brazil, there have hardly been any efforts to build systems for industrial clients. Representatives from industry associations, universities, government ministries, development banks and the solar thermal sector met in the capital, Brasilia, on 23 May to discuss barriers to market adoption and opportunities to increase it.
 
“Currently, solar thermal technologies are mainly used in Brazil’s industry to heat changing rooms and canteens,” said Professor Elizabeth Duarte Pereira, who works at the university in Belo Horizonte, and called for a dedicated strategy to generate interest in industrial solar heat applications. She also criticised the focus on the electric power sector for providing energy efficiency. In addition, small and medium enterprises (SMEs), the backbone of the country’s industrial sector, had found it difficult to obtain funding from government programmes and development banks.
 
“We need credit lines that include SHIP technologies and target SMEs,” said Rafael Campos, President of the Brazilian solar thermal industry association Abrasol, one of the partners to Solar Payback.
 
The attendees supported the recommendation made in the Solar Heat for Industry study to set up an efficiency programme similar to the Programa de Eficiência Energética (PEE), which the Agência Nacional de Energia Elétrica established in the electricity sector. The scheme, which would be managed by the Agência Nacional do Petróleo, Gás Natural e Biocombustíveis, was thought to be an effective tool to stimulate the SHIP market. In the electricity sector PEE stipulates that electricity suppliers must invest 0.5 % of their net turnover in energy efficiency measures.
 
The attendees also agreed that considerable effort was needed to communicate the benefits of SHIP technologies to potential customers in industry, as most beverage, food, leather and textile companies had not yet been made sufficiently aware of their solar thermal options in production. The next item on Solar Payback’s agenda, a free-of-charge conference to be held in Portuguese during the Intersolar South America, is hoped to rectify the situation.
