GEA is investing twelve million euros in the British company Caldera. Caldera has developed electric Storage Boilers that can store electricity in the form of heat that can be extracted on demand. The product is suitable for a wide area of applications. GEA sees it as an important element within holistic concepts for decarbonising process heat demand between 100 and 200 °C, which is typical for many industrial processes.

Decarbonisation of industrial process heat: GEA heat pumps and Caldera Storage Boilers are complementing each other

GEA combines its process and heating expertise to develop systems to reduce energy consumption, reuse energy and upcycle waste heat streams in customer sites. Heat pumps are a key enabler for the decarbonization of process heating in industries such as food manufacturing, dairy production, breweries, distilleries and the pharmaceutical sector.

By combining GEA’s heating solutions with Caldera’s innovative storage boilers, it is possible to offer an affordable and reliable way of providing industrial customers with all-electric – and therefore low-carbon – heat. A combined system joins the benefits of a highly efficient heat pump with the flexibility and fast response time of a storage boiler. This allows for the efficient decarbonisation of steam networks with varying demand profiles that are typical across a broad range of industries.

High temperatures in São Paulo state in early October reinforced producers’ concerns, since this scenario can affect both fruits that are on the trees (from the current season, 2023/24) and the production of the next crop (2024/25), especially non-irrigated areas. Therefore, in mid-October, citrus growers were waiting for the rainfall in major producing regions.

So far, the biggest challenge for the current season (2023/24) has been the fact that fruits have wilted, which affects directly the quality, according to players surveyed by Cepea. In normal conditions, this quality loss would press quotations down; however, due to the limited supply this season, prices remain firm.

As for the 2024/25 crop, scenarios are distinct between irrigated and non-irrigated areas. In irrigated regions in São Paulo state, the fruit development is more advanced, but producers were still concerned with high temperatures.

On the other hand, most trees in non-irrigated areas have not blossomed yet. Thus, the return of rains is essential to mitigate the lack of soil humidity and encourage the blossoming.

Most part of São Paulo state registered high temperatures in early September. This scenario brought concerns for citrus growers, who may face another year of significant heat waves.

Climatempo says that heat waves in September have become more common in most part of Brazil; however, they have been more intense and are lasting longer.

2024/25 CROP – São Paulo state and Triângulo Mineiro may harvest 215.78 million 40.8-kg boxes in the 2024/25 orange season, according to data released by Fundecitrus on September 10. The volume may be 30 % less than in the crop before, which registered average production, and below the first projection, of 232.38 million boxes.

The decrease is related to the smaller fruit size, due to the dry and warm weather. The weather also accelerated the harvesting pace, since it influenced the ripening. More than half of the crop can be harvested in this dry weather scenario because rains are forecast only for late September.

The volume of rainfall was small in almost all areas in the citrus belt, except in the southwestern region of São Paulo. Fundecitrus indicates that the only area where the production is expected to increase in this season is the southwest of SP – the harvest may be 19 % higher than in 2023/24. In other regions, the production decrease can be between 28 % and 60 %.

The new heat wave in São Paulo state has been concerning citrus growers. Temperatures are higher than those registered in the last wave, in September, and lasting longer. Thus, many producers say that the weather may affect the 2024/25 production, but it is still early to estimate possible impacts.

Up until mid-November, high temperatures have been affecting areas with fruitlets. It is worth noting that, in the heat wave observed in September, areas with fruitlets (which had registered flowers in August) were the most affected, since weather conditions have caused fruitlets to fall.

Areas with late flowers (verified in less than 30 days) may also be damaged by the hot weather – these flowers blossomed earlier and the development stage is more advanced. Moreover, citrus growers indicate possible impacts on bigger fruits, especially in trees with high incidence of greening, with less leaves and/or in bad nutrition.

In irrigated areas, in turn, damages tend to be mitigated, since flowers are in a more advanced stage. However, these areas are located in the north of São Paulo state, where temperatures are usually higher.

As for 2023/24 oranges, players surveyed by Cepea report impacts on the quality. Many fruits are withered and sunburned, and consumers usually do not want to buy fruits with these conditions – in many cases, it is necessary to accelerate the harvest in order to avoid the premature fruit fall.

TAHITI LIME – The heat wave has also been affecting the tahiti lime. As rains have not been frequent in major producing regions, the supply has not increased in a significant way, and most fruits are small.

Despite the smaller size, producers have been harvesting fruits in order to take advantage of high prices and to avoid that the hot weather affects the quality even more.

The second fortnight of September was marked by extremely high temperatures in São Paulo State. This scenario warned citrus growers, since intense heat may damage the oranges from both the current (2023/24) and the coming seasons (2024/25).

In the 2023/24 crop – which is currently being harvested –, the biggest problem has been wilted fruits, according to Cepea collaborators. This feature reduces both quality and remuneration, since the oranges become lighter because of the loss of water. On the other hand, for the industry, fruits quality rises slightly, due to higher yield and ºbrix.

On the other hand, for the coming season (24/25), although the effects of the hot weather from September are still uncertain, growers are concerned about fruitlet fall, which may be higher than the usual. This context could lead to a lower number of fruits per tree.

Also, the fact that many orchards have been affected by greening makes the situation worse. A survey from Fundecitrus (Citrus Defense Fund) shows that 38.06 % of the trees in the citrus belt (São Paulo + Triângulo Mineiro) have had symptoms of the disease this year, 56 % above that from 2022 and the sixth consecutive year of increase in the incidence of greening.
