has started up a highly efficient electrolyzer
for the production of hydrogen. The system is
based on ceramic, solid-oxide electrolysis cells
(SOECs), and is said to consume less power than alternative
technologies, such as alkaline electrolysis (which
suffer from corrosion) or polymer electrolyte membrane
(PEM) electrolysis (which needs expensive rare-earth
metals). Also, no platinum catalyst is required.
Over the past eight years, Toshiba has been developing
SOEC systems based on scandia-stabilized zirconia
(ScSZ) as a solid electrolyte, and a hydrogen electrode
made of nickel-oxide-gadolinium-doped ceria (NiOGDC).
Since 2014, the 1-kWh system has undergone
testing, with support from the New Energy and Industrial
Technology Development Organization (NEDO; Kawasaki,
Japan; www.nedo.go.jp) under the authority of
Japan's Ministry of Economy, Trade and Industry.
This year, the company plans to demonstrate a
10-kWh-class system, and has the goal of producing
100-kWh-class systems capable of generating 30 m3 /h
of H2. Ultimately, Toshiba aims to create practical SOEC
systems that can produce (using electricity from solar
or wind generators) and store large volumes of H2, and
then utilize the H2 to generate electricity (using solidoxide
fuel cells) during nighttime or windless days. The
goal is for a charge-discharge efficiency of 80%.
Catalytic hot-gas filters
reduce dust and pollutants
I
n late April, Unifrax I LLC
(Tonawanda, N.Y. ; www.unifrax.
com) and Haldor Topsøe A/S
(Lyngby, Denmark; www.topsoe.
com) signed a partnership agreement
to begin a joint global effort to
commercialize an innovative new line
of catalytic filter candles. This new
product family - developed for industrial hot-gas filtration
- will be marketed as TopFrax filters.
The TopFrax catalytic filter candle is designed to remove
oxides of nitrogen (NOx) and particulate matter,
and will also be launched in a version capable of removing
volatile organic compounds (VOCs), CO and dioxin
that are generated in many industrial processes, including
glass, cement and metals production, waste incineration
and biomass processing.
Key features of these filters include: high-efficiency filtration
of particulate matter (>99%), NOx removal efficiency
(>95%), low ammonia slip, and filter porosity above 80%,
says Topsøe. TopFrax filters can operate at temperatures
up to 400°C (750°F), are compatible with sorbents, and
are non-combustible, and corrosion resistant. Like the
catalytic bag filters launched earlier this year (CE, March
2015, p. 7), these candle filters combine the removal of
NOx, VOC, CO, dioxin and particulate matter into one integrated
process, thus reducing capital and operating costs,
as well as the footprint for pollution-control equipment.
