Who is Motus Energy?
-
Motus Energy is an EPC and Investment company part of Gruber
Logistics Group (www.gruber-logistics.com). The core business of the
company is the construction of renewable energy system and
biomass trading
-
Motus Energy is the first EPC contractor that has realized and
managed in Italy a combined pellet gasification and CHP Plant
providing to the Client as operation warranty a reimbursement of
production lack
-
Motus Energy is the first EPC contractor that has realized a biomass
gasification plant obtaining all the authorizations including the
emission authorization by Province of Bozen (Provincia di Bolzano, Ripartizione
29, Ufficio aria e rumore, autorizzazione n. 4679, prot. Nr. 366012)

Technology Innovations – Wood Gasifier
Core business: energy production from refined biomass
Profitability from an energy plant means:
-
Production planning with programmable sources
Availability, cost and environment impact of fuels
High efficiency of the production systems
System scalability
INNOVATION OF WOOD GASIFIER
Technology Innovations – Wood Gasifier
Why Innovation?
-
Production Planning with programmable sources
No programmable sources (sun, wind) in the renewable energy production
system of countries may result critical situations in terms of electrical grid
stability in long term period
In Italy recently  The electrical authority can disconnect arbitrary no
programmable plant for safety grid reasons = loss of profitability

Why Innovation of Wood gasifier?
-
Possibility to use low cost and low impact fuel, with high availability in an
high efficiency/scalability system
-
Low cost fuels  savings during purchasing and plant operation
Availability of fuels  warranty of supply
Low environment impact  accepted from local communities
High efficiency  more electrical production  higher revenues
High scalability  easier authorization path, localization near final users,
saving of electrical losses
Technology Innovations – Wood Gasifier
Why gasifier?
Wood is a solid fuel. If we want use it in a Diesel system we need gas or
liquid state
Wood fuel?
All fuels have to be refined, because energy production systems need stable
input
Stable Input = simplier processes  lower investment costs
Wood Cips (Not Fully refined)
Wood Pellet (Fully refined)
Technology Innovations – Wood Gasifier
Cips or Pellet Wood?
Wood -------- Refining 1 -------- > Wood Cips ----- Refining 2 ------> Wood Pellet
(solid state)

Refining 3

Gas ready

Engine
Refining phase 2 = Refining phase 3 but solid process costs less than gas
process
Pellet using is preferable

General technical details of our system
-
Modules of 199 kWp – 270 kWt (32% electrical efficiency)
Man diesel engine + turbine on exhausted gas
Assembled system, fast installation
Feed with wood pellet or other selected biomass (new development)
Low emissions level compatible with Italian law (DM 6 luglio 2012, art. 8 comma
7-allegato 5)
- Possibilities to combine modules in order to increase the power
- High availability of the system (> 7.500 hours guaranteed)
Other system infos
- Production warranty with an O&M contract
- Approved by more than one primary credit institutes in Italy
- Investment of Motus Energy / Gruber Logistics group in new plant during year
2012: around 7 milion € (first plants in Italy)
- 80 modules already installed in Europe (Germany and Italy) at march 2013, 3
years track record
Technology Innovations – Wood Gasifier
General financial / risks management
- Full EPC costs  (4,9 – 6,1 mln € / MWp) depends by specific site/n. modules
- Investment costs / EBITDA  5-6,5 years depends by specific site/heating using
- Risk of fuel supply  Motus is fully connected to Gruber Logistics Group, an
international company, and has agreements with different large biomass
producers
-
Risk of fuel price  pellet is a commodity with low inflation risk
Risk of fuel price  warranty price for a defined period
Risk of fuel price  partial compensation by heat contract updates
Risk of plant stop by authorities  biomass is a programmable source
