Periodic Reporting for period 1 - POWERICE (Organic Rankine Cycle Cogeneration Plant of one-farm size using rice straw as single fuel)
Reporting period: 2017-01-01 to 2017-03-31
POWERICE is the unique turn-key cogeneration plant designed for single rice farms, using rice straw as only source of fuel. While widening the potential market, this carries on a distributed energy production model, reducing the demand from the national grid, and reducing costs and wastes resulting from energy transportation.
Definition of an execution plan with the technical/operational conditions of the combined technology
Ensuring the freedom to operate analysis (FTO)
Study of the main features of rice farms around the world, to determine the most suitable areas for commercialisation
Study of silica market and financial approach considering silica withdrawal by POWERICE seller as a payment form
The results indicate that:
Rice straw ash has viable markets in POWERICE’s target markets.
The optimal solution is a 300 kWe type ORC unit (100kWe for Italy) recovering up to 710 kWth of thermal power from a boiler.
Several Nations were identified as a potential market, according to their specific rice growing model and public incentives for biomass energy
Silica can be used and valorised in exterior supply chains, thus allowing a lower equity and / or mortgage for the purchase of POWERICE
Currently, Italy has about 2,500 farms, out of a total 4,000 in Europe. The USA market has about 7,500 farms. Europe has 8 significant rice producing countries including Italy, Spain, Greece, Portugal, France, Bulgaria, Romania and Hungary that produce a combined total of 3 million tonnes of rice per year on average.
Given that each hectare of rice crop has the potential to yield approximately 9.2 tonnes of rice straw, a farmer producing 100 ha of rice yields about 920 tonnes of rice straw. About 15% of burnt rice straw becomes ash, implying about 150 tonnes of rice straw ash from 100 ha that can act as a source of income in silica markets.
