BIOMASS-TO-ENERGY CONVERSION
An increase in the demand for biomass for conversion to heat by combustion is likely. The potential role for hemp in supplying this demand is discussed in this article. For hemp, key characteristics such as net calorific value, ash content, and melting behavior, and the risk of corrosion or polluting emissions, are all favorable. Low bulk density and size reduction difficulties might limit its use for pellet production and in small boilers; its use in electricity generating plants and medium-to-large boilers would have better prospects. To mazimize profitability, an agronomy program to achieve high yields at the lowest cost is required. In the Irish climate, this would entail early sowing (late March/early April), a low seed rate (~30kg/ha), and variety selection for maximum stem yields over 10t/ha is attainable. Cost analysis shows that an energy price of about Euros6/GJ is required to achieve a profit level similar to conventional food enterprises. Arable farmers would welcome a break crop in rotation with cereals. Processors needing a year-round fuel supply might be expected to welcome an autumn-harvested crop as part of a mix with spring-harvested crops such as miscanthus and willows. A mix of energy crop species would improve biodiversity and visual impact. Hemp should be a strong contender to be part of the energy crop mix.
The varieties studied were Kompolti, Ferimon, and Fedrina 74. They had stem yields of 12.6t/ha, 11.7 t/ha and 11.6 t/ha respectively. A comparison of the net calorific value of hemp to other cellolusic biomass showed each as follows:
Hemp 13.4
Wood residues 10.0
Straw 13.0
Peat 8.9
(the gross values, respectively, were: 18.5, 19.7, 18.0, 21.5).

HEMP IN IRELAND
By the eighteenth centrury, hemp had been grown in every county in Ireland. Along with flax, it was a staple of the Irish economy. Textiles and cordage productions were main industries in the Emerald Isle, but time has eroded these and now hemp is scarce to be seen.
However, it is making a comeback. Jim McDonald and son a few years ago opened The Hemp Store in Dublin, selling clothes, paper and other hemp items. Farmers are taking it up again, as it is an easy crop to grow and harvest, and hemp provides fibre, pulp, food, oil, and now, building material.
This last use of hemp is covered extensively by Steve Allin in his comprehensive book Building with Hemp. In it he covers every angle of this aspect, going into great detail and providing 300 full colour images. He starts with the basic history of hemp and then goes on to examine the materials involved, mainly hemp hurds and lime, which is the shells of little sea creatures who died some millions of years ago.
Like all well written books on a current subject, it has an index and a resource guide, so it is a seminal work which is user friendly. I learned a lot from it myself, not just about hempcrete and other hemp building materials, but about architecture in general. Building with Hemp is published in Ireland by Seed Press; more information can be found at www.hempbuilding.com and the email address is seedpress@eircom.net
Another Irish effort in the realm of all things hemp is Simon Jennings' work to start using hemp biomass for blanks in surfboards, his surfing podcasts are famous the world over and include an interview with me about the future of the hemp industry. He is known as the Irish surfer, and can be found at times off the coast of Donegal when the waves are rolling in.
